Measuring video-program viewing
Abstract
A computer-implemented method of using video program viewing activity data as input to an aggregation engine built on the Hadoop MapReduce framework which calculates second-by-second video viewing activity for Linear, DVR, and VOD program level viewing including measuring trick play activity with results aggregated to the analyst's choice of program, program airing, channel, house attributes, device attributes, geographic area, demographic attributes, viewing date, or any combination of these fields, for each second of program content represented in the video program viewing data. The source data may be extracted from a database defined according to the Cable Television Laboratories, Inc. Media Measurement Data Model defined in "Audience Data Measurement Specification" as "OpenCable™ Specifications, Audience Measurement, Audience Measurement Data Specification" document OC-SP-AMD-I01-130502 or any similar format. These metrics provide detailed data needed to calculate information on customer viewing behavior that can drive business decisions for service providers, advertisers, and content producers.

BACKGROUND - PRIOR ART
0007I have not found any relevant prior art at the present time.
BACKGROUND INFORMATION
General statement of problem
0008With the ever increasing number of consumer choices for television viewing, it is important for advertisers, content producers, and service providers such as cable television and satellite television and internet protocol television companies to be able to accurately measure audience viewership. I have discussed this problem extensively in my prior applications. This application teaches how to analyze video viewing activity related to sessionized or program-based linear viewing, digital video recording playback viewing, and video on demand viewing using the Hadoop MapReduce distributed computing framework. The reader will readily recognize that video on demand encompasses a wide range of video content including, but not limited to, cable and/or satellite television video on demand, all variety of video content delivered electronically across a network, and online educational videos.
Existing Tools for Data Analysis
0009In my prior application <patcit id="pcit0007" dnum="US56707312A"><text>U.S. Application Ser. No. 13/567,073 filed on Aug 5, 2012</text></patcit> I taught how to analyze sessionized or program-based linear viewing, digital video recording playback viewing, and video on demand viewing by loading the viewing activity data into arrays in the memory of a computer and then running algorithms against that data. In certain cases, an analyst may wish to use the Hadoop MapReduce distributed computing framework to analyze sessionized or program-based linear viewing, digital video recording playback viewing, and video on demand viewing. I have not identified any patents that teach how to use MapReduce to solve this problem.
SUMMARY
0010In accordance with one embodiment, I disclose a computer-implemented method of aggregating sessionized or program-based linear viewing, digital video recording playback viewing, and video on demand viewing using the Hadoop MapReduce distributed computing framework. This will allow an analyst to aggregate second-by-second video viewing activity for this kind of viewing. Once this data has been aggregated, it can be used in any number of downstream analytic processes to provide detailed information on customer viewing behavior which can be used to drive business decisions for service providers, advertisers, and content producers.
ADVANTAGES
0011By using the Hadoop MapReduce distributed computing framework to aggregate sessionized or program-based linear viewing, digital video recording playback viewing, and video on demand viewing, an analyst can harness the power of hundreds or even thousands of processors working in parallel to solve the problem of aggregating this video viewing activity data. This will allow an analyst to work with data sets of all sizes including extremely large data sets. The resulting files can be loaded to a relational database for various analytics similar to what I have taught in my other Patent Applications referenced previously. Additionally, the resulting files can be used in other Hadoop processes to correlate video viewing activity with other social media activity, with weather, with other programming content, and similar uses.

Note on Media Measurement Data Model
0016Cable Television Laboratories, Inc. has published an "Audience Data Measurement Specification" as "OpenCable™ Specifications, Audience Measurement, Audience Measurement Data Specification" having Document Control Number <b>"OC-SP-AMD-I01-130502"</b> copyright Cable Television Laboratories, Inc. 2013 which describes a Media Measurement Data Model (MMDM) database design which can be used as a source of data for the MapReduce Aggregation Engine <b>200</b> which I teach how to build in this Application. The teaching in my present application can be implemented in conjunction with that Media Measurement Data Model or with any number of data models as long as the required input data is provided as described herein.
0017Additionally, my MapReduce Aggregation Engine <b>200</b> creates files which may be used to load additional tables in a Media Measurement Data Model such as the one published by Cable Television Laboratories, Inc. These files are described in <b>FIG's 5</b> to <b>8.</b>
0018<b>Note: Numbering in the Drawings</b> - The numbers in the drawings are usually, but not always, in sequential order.
0019<figref idref="f0001"><b>FIG. 1</b></figref> provides an overview of an exemplary process for collecting viewer interaction data derived from a plurality of viewers interacting with video content that was delivered on a plurality of video asset viewing devices delivering content through a network and then loading that data to a Media Measurement Data Base <b>100.</b> This figure illustrates several viewers interacting with video asset viewing devices to view content which was delivered to those devices across a network and then to collect viewing activity from those devices.
0020In this nonlimiting example, the purpose is not to describe in detail the operations of a video content delivery network or a data collection process, but simply to show how the data that is collected from that system can be made available to my MapReduce Aggregation Engine <b>200.</b>
0021It begins with Viewer Viewing Linear Content <b>9200</b> who is interacting with a set-top box <b>9210</b> and television <b>9220</b> as he views linear content. The set-top box <b>9210</b> interacts with a Video Content Delivery System <b>9250</b> which delivers the content across a Network <b>9230.</b>
0022It continues with Viewer Viewing DVR Content <b>9202</b> who is interacting with a set-top box <b>9210</b> and television <b>9220</b> as he interacts with DVR content, recording content and playing back recorded content using various modes including trick plays. The set-top box <b>9210</b> interacts with a Video Content Delivery System <b>9250</b> which delivers the content across a Network <b>9230.</b>
0023It continues with Viewer Viewing VOD Content <b>9203</b> who is interacting with a set-top box <b>9210</b> and television <b>9220</b> as he interacts with VOD content, playing the content using various modes including trick plays. The set-top box <b>9210</b> interacts with a Video Content Delivery System <b>9250</b> which delivers the content across a Network <b>9230.</b>
0024It continues with Viewer viewing video content using tablet, smart phone, IP TV, or other video video viewing device <b>9204</b> who is interacting with a variety of Video Viewing Devices <b>9212,</b> including but not limited to tablet, smart phone, IP TV, PC, etc. The video viewing device interacts with a Video Content Delivery System <b>9250</b> which delivers the content across a Network <b>9230.</b>
0025Video Content Delivery System <b>9250</b> then interacts with a Viewer Interaction Data, Data Collection System <b>9260</b> which collects all manner of viewer interaction data including Linear viewing including time-shifted linear viewing, Digital Video Recorder recording and playback/viewing, and Video on Demand viewing. The Viewer Interaction Data, Data Collection System <b>9260</b> then processes the data as needed to load it to a Media Measurement Data Base <b>100.</b> The data in the Media Measurement Data Base <b>100</b> can then be used as input to my Aggregation Engine <b>200</b> as described in <figref idref="f0002"><b>FIG 2</b></figref><b>.</b>
0026<figref idref="f0002"><b>FIG. 2</b></figref> illustrates an exemplary media measurement process from creation of the <b>Video Program Viewing Activity Data File 130</b> to creation of the various aggregated viewing activity files <b>(Parts 220, 230, 240, 250)</b> which can then be provided to downstream analytic processes as shown by <b>Provide Files to Downstream Analytic Processes 210.</b>
0027As noted previously, the video program viewing activity may be sourced from a Media Measurement Database such as the one described in the Cable Television Laboratories, Inc. specification. The populating of the Media Measurement Database <b>100</b> is beyond the scope of this application and so only brief remarks will be made in reference to that. There are video viewing data collection systems that are commonly used in the industry for collecting channel tuning or video viewing activity data including switched digital video systems, set top box applications, internet protocol video viewing applications, and other video viewing applications. I have discussed these in detail in my prior applications. These systems enable the collection of the video viewing events which can be loaded to a Media Measurement Database <b>100.</b> From such a database, <b>Video Program Viewing Activity Data</b> can be extracted in a format similar to that shown in <figref idref="f0003 f0004 f0005 f0006 f0007 f0008 f0009 f0010 f0011 f0012 f0013 f0014 f0015 f0016"><b>FIG 3</b></figref> Video Program Viewing Activity Data File <b>130.</b>
0028Proceeding with the review of <figref idref="f0002"><b>FIG 2</b></figref><b>,</b> the process begins with <b>Media Viewing Measurement Process Overview 110.</b> The first step is to extract the video viewing events as per <b>Extract Video Viewing Activity Data from Media Measurement Data Base 120.</b> Those skilled in the art will have no difficultly creating a database query or similar process to extract data from a Media Measurement Database <b>100</b> or other source and making it available in a format similar to that defined in <b>Video Program Viewing Activity Data File 130.</b> The file structure is defined in <figref idref="f0003 f0004 f0005 f0006 f0007 f0008 f0009 f0010 f0011 f0012 f0013 f0014 f0015 f0016"><b>FIG 3</b></figref><b>Video Program Viewing Activity Data File 130</b> which describes an exemplary format for the input video program viewing activity data.
0029This data file may contain three types of viewing activity depending on the query defined by the analyst. The three types are: <ol id="ol0009" compact="compact"><li>a) Sessionized linear viewing activity (LVA)</li><li>b) Digital video recording viewing activity (DVR)</li><li>c) Video on demand viewing activity (VOD) These are defined next:</li></ol>
0030<b>Sessionized linear viewing activity (LVA) -</b> Sessionized linear viewing activity is derived from linear tuning events. For linear tuning events which fit within program boundaries, the tuning event may be enriched as described in the Cable Television Laboratories, Inc. specification. For linear tuning events which cross program boundaries, the tuning event is divided into shorter duration tuning events as needed to fit within program boundaries as described in the specification; they are also enriched with additional fields. Because the viewing activity has been transformed to fit within program boundaries, I refer to it as program-based viewing. Linear viewing activity may be extracted from the Cable Television Laboratories, Inc. MMDM or from any source that is able to provide the data in a format suitable for this process.
0031A non-limiting example will help to explain this: <ul id="ul0003" list-style="none" compact="compact"><li>Device 100 has a linear tuning event consisting of a Tune to ABC at 6:55:00 PM and tune away from ABC at 8:07:59 PM. Assume a program schedule on ABC of News from 6:30:00 PM to 6:59:59 PM, followed by Action Show from 7:00:00 PM to 7:59:59 PM, followed by Sports Show from 8:00:00 PM to 8:29:59 PM. Using this sample data set, we see that the linear tuning event from Device 100 can be sessionized as follows: <ol id="ol0010"><li>i. Session 1: Channel ABC from 6:55:00 PM to 6:59:59 PM tuned to Program 'News'.</li><li>ii. Session 2: Channel ABC from 7:00:00 PM to 7:59:59 PM tuned to Program 'Action Show'.</li><li>iii. Session 3: Channel ABC from 8:00:00 PM to 8:07:59 PM tuned to Program 'Sports Show.' This is defined in more detail in the specification that Cable Television Laboratories, Inc. has published as "Audience Data Measurement Specification" referred to previously.</li></ol></li></ul>
0032The same video content may air multiple times, so when viewing is being measured it is necessary to track the Program information, Program Airing information, and Channel information along with other fields.
0033<b>Digital video recording viewing activity (DVR)</b> - DVR viewing activity may be extracted from the Cable Television Laboratories, Inc. MMDM or from any source that is able to provide the data in a format suitable for this process. As a non-limiting example, a PROGRAM may be a baseball game and a PROGRAM_AIRING may be the initial airing of the game followed by a replay later that day (thus two airings). Because a DVR asset airs on a certain channel at a certain time, DVR assets are also linked with Channel.
0034When the viewer records a program, they may record any of several airings. Also the program my air on different channels for the original and the replay. For these reasons, the DVR recording and subsequent playback must identify the Program information, Program Airing information, and Channel information along with other fields.
0035<b>Video on demand viewing activity (VOD) -</b> VOD viewing activity is extracted from the Cable Television Laboratories, Inc. MMDM or from any source that is able to provided the data in a format suitable for this process. As a non-limiting example, a program may be any VOD asset, a movie, a sporting event, an online class, etc. The concept of a PROGRAM_AIRING does not apply to VOD. As to channel, because a VOD Program airs on the preassigned VOD channel, the channel information is not particularly informative in the context of VOD, so it is ignored for purposes of this Application.
0036These three types of viewing, LVA, DVR, and VOD, all share the characteristic that for measurement purposes, the measuring activity must be based on position in the content rather than a time element such as UTC time or local time. Measuring viewing activity based on position in the content enables creation of metrics having the same basis across LVA, DVR, and VOD viewing. Furthermore, when measuring based on position in the content, it is necessary to use a fixed reference point such as the actual start of the content. To illustrate, for a DVR recording, not every viewer will record the content beginning at the start of the program. So using position in the recording for measurement would not yield comparable results. Instead it is required to use a fixed reference point (the start of the content), in the actual content, not the start of the recording, and measure viewing from that fixed reference point. By using this fixed reference point, we can measure consistently regardless of whether the user begins recording at the beginning or some other point in the content. The same concept is applicable to LVA and VOD viewing.
0037Resuming with the review of <figref idref="f0002"><b>FIG 2</b></figref><b>,</b> those with reasonable skill in the art will readily recognize how to create the <b>Video Program Viewing Activity Data File 130 (</b><figref idref="f0003 f0004 f0005 f0006 f0007 f0008 f0009 f0010 f0011 f0012 f0013 f0014 f0015 f0016"><b>FIG 3</b></figref><b>).</b> Note that there is a single record layout for LVA and DVR and VOD. In the case of VOD, the PROGRAM_AIRING_INFO <b>1020</b> and the CHANNEL_INFO <b>1030</b> may be left blank because these fields are not applicable to VOD.
0038Proceeding with the review of <figref idref="f0002"><b>FIG 2</b></figref><b>,</b> the <b>Video Program Viewing Activity Data File 130</b> is then passed to a <b>Data Explosion Process 140.</b> In this process the individual viewing events are exploded such that there is one record created for every second of the viewing duration represented in the video program viewing activity record. Depending on the criteria by which the analyst is aggregating the data, various fields can be omitted from the <b>Video Program Viewing Activity Data File 130</b> file because the MapReduce process will not use them. I have included these additional fields to provide a comprehensive picture recognizing that one can always drop the fields that they choose not to use.
0039The computer algorithm that the <b>Data Explosion Process 140</b> runs to create the Video Program Viewing Detail File <b>150</b> is as follows:
Looping process to create the video program viewing detail records:
0040<img file="EP2846292A1_D0001.tif" />
0041The explosion process can be run in an alternative manner to achieve the same result. I have included this alternative embodiment.
Alternative Embodiment #1
0042If the activity duration is provided, the looping construct can be done as follows: <img file="EP2846292A1_D0002.tif" />
0043Note: In each case the <b>Video Program Viewing Detail File 150</b> records can be written directly to the Hadoop Distributed File System (HDFS) so that the video program viewing detail records are ready for use by the MapReduce distributed computing framework.
Note:
0044The <b>Video Program Viewing Activity Data File 130</b> can be provided by the Extract <b>120</b> process in any computer readable format including, but not limited to, database tables, flat files, JSON messages, and XML messages. Alternatively, such video viewing events can be collected directly from the source without the need for a Media Measurement Database <b>100.</b> In such a case, those events can still be provided as video viewing activity in a format similar to that shown in <figref idref="f0003 f0004 f0005 f0006 f0007 f0008 f0009 f0010 f0011 f0012 f0013 f0014 f0015 f0016"><b>FIG 3</b></figref> for use by the <b>Data Explosion Process 140.</b>
0045For each of these embodiments, at the completion of Data Explosion Process <b>140,</b> one record has been written to the Video Program Viewing Detail File <b>150</b> for each second of the viewing duration represented in the video program viewing activity record. The Sample Data in <figref idref="f0003 f0004 f0005 f0006 f0007 f0008 f0009 f0010 f0011 f0012 f0013 f0014 f0015 f0016"><b>FIG 3</b></figref> shows a non-limiting example of the input data for the <b>Data Explosion Process 140.</b> The Sample Data in <figref idref="f0017 f0018 f0019 f0020 f0021 f0022 f0023 f0024 f0025 f0026 f0027"><b>FIG 4</b></figref> shows a non-limiting example <b>of a partial set</b> of the data produced by the <b>Data Explosion Process 140.</b> The reader will note that <figref idref="f0017 f0018 f0019 f0020 f0021 f0022 f0023 f0024 f0025 f0026 f0027"><b>FIG 4</b></figref> sample data contains one record for every second of the viewing activity represented in the input data.
0046Those skilled in the art will readily recognize that the <b>Data Explosion Process 140</b> is suitable for running in parallel on multiple computers simultaneously with each process creating Video Program Viewing Detail File records that can be fed into the MapReduce Aggregation Engine <b>200.</b>
0047Proceeding with the review of <figref idref="f0002"><b>FIG 2</b></figref><b>,</b> the Video Program Viewing Detail File <b>150</b> data residing in HDFS is now ready for use by the MapReduce Aggregation Engine <b>200.</b> The MapReduce Aggregation Engine <b>200</b> runs various word count algorithms against the incoming data. Each word count algorithm will aggregate the data to a separate level as shown in <figref idref="f0002"><b>FIG 2</b></figref><b>(Parts 220, 230, 240, 250)</b> with the details shown in <b>FIG's 5 - 8.</b>
0048The MapReduce process can be coded in JAVA or in Pig. I have coded this in Pig. The code below can be used to create the four output files reviewed in the Drawings <b>(FIG's 5 to 8):</b><ul id="ul0004" list-style="none" compact="compact"><li>Aggregated Sessionized Linear Viewing Activity (LVA) File <b>220</b></li><li>Aggregated DVR Viewing Activity (DVR) File <b>230</b></li><li>Aggregated VOD Viewing Activity (VOD) File <b>240</b></li><li>Aggregated Video Program Viewing File <b>250.</b></li></ul>
0049Using these outputs, the reader will have a comprehensive set of aggregated video viewing metrics. The reader should recognize that the aggregation logic shown below provides several illustrations of what can be done. Additional aggregation combinations will be obvious to those skilled in the art.
Creating the Aggregated Sessionized Linear Viewing Activity (LVA) File 220
0050The Pig Latin coding to create the Aggregated Sessionized Linear Viewing Activity (LVA) File <b>220</b> is shown next.
0051This summarization aggregates Sessionized Linear Viewing Activity for each combination of Program, Program Airing, Channel, Geographic, Demographic, and Date by the Playback Mode. The result provides a summary of Sessionized Linear viewing for each second of the program content with the viewing activity broken out by the playback mode (PL, F1, F2, R1, R2, etc.).
0052As a nonlimiting example, if a program was 1800 seconds (30 minutes) duration, the analyst would have counts of how many devices viewed second 0 in PL mode, then second 1 in PL mode, etc. to second 1799. Additionally, he would have similar data for each of the other playback modes (F1, F2, R1, R2, etc.) for each of the 1800 seconds of the program. By matching this data with the content being shown, the analyst can now chart how many devices saw each second of the content in the respective playback modes. <img file="EP2846292A1_D0003.tif" /><img file="EP2846292A1_D0004.tif" /><img file="EP2846292A1_D0005.tif" /><b>Note:</b> VIEWING_TYPE <b>1290</b> is carried forward to identify the type of viewing when files are combined downstream.

0060The result provides a summary of DVR viewing for each second of the program content with the viewing activity broken out by the playback mode (PL, F1, F2, R1, R2, etc.).
0061As a nonlimiting example, if a recorded program on the DVR was 1800 seconds (30 minutes) duration, the analyst would have counts of how many devices played back second 0 in PL mode, then second 1 in PL mode, etc. to second 1799. Additionally, he would have similar data for each of the other playback modes (F1, F2, R1, R2, etc.) for each of the 1800 seconds of the recorded program and the corresponding viewing.

Creating the Aggregated VOD Viewing Activity (VOD) File 240
0069The Pig Latin coding to create the Aggregated VOD Viewing Activity (VOD) File <b>240</b> is shown next.
0070This summarization aggregates Video On Demand Viewing Activity for each combination of Program, Geographic, Demographic, and Date by the Playback Mode. Note: VOD does not use Program Airing or Channel in the same way that linear and DVR use this, so those fields are not included in VOD. The result provides a summary of VOD viewing for each second of the program content with the viewing activity broken out by the playback mode (PL, F1, F2, R1, R2, etc.).
0071As a nonlimiting example, if a Video On Demand lease was for a program that was 1800 seconds (30 minutes) duration, the analyst would have counts of how many devices played second 0 in PL mode, then second 1 in PL mode, etc. to second 1799.

Creating the Aggregated Video Program Viewing File 250
0079The Pig Latin coding to create the Aggregated Video Program Viewing File <b>250</b> is shown next. (LVA), digital video recording viewing activity (DVR), and video on demand viewing activity (VOD) as these are provided in the input data. The viewing can then be grouped by each combination of Program, Geographic, Demographic, and Date by the Playback Mode. The result provides a summary of overall viewing from the various sources (LVA, DVR, VOD) for each second of the program content with the viewing activity broken out by the playback mode (PL, F1, F2, R1, R2, etc.) for the data as represented in the input data. As a nonlimiting example, this aggregation will provide insight into total viewing activity during each second of the program content.
0080This data can be used to create an overall picture of the viewing activity. It can also be used to determine as the denominator in calculations which compare the percentage of LVA viewing or DVR viewing or VOD viewing to overall viewing of this content.

Overview of FIG's 5 to 8
0096FIG's 5 to 8 review several outputs which are created by the MapReduce Aggregation Engine <b>200.</b> There are multiple ways to aggregate the data depending upon the desired result. In FIG's 5 to 8 I have shown several options. A person skilled in the art will readily identify additional aggregations options that fall within the spirit and scope of this Application.

0099The reader will note the sample data is organized by Program 1 Airing 1 and then Program 1 Airing 2 and then Program 1 Airing 1 and Airing 2 combined. Within these groupings, there are sections for the various playback modes of PL, F1, F2, R1, R2 as they occur.

0100The reader will observe that for each set of aggregated viewing activity, along with the identifying fields, there are <b>PLAYBACK_MODE 1710, PLAYBACK_POSITION 1720, and PLAYBACK_MODE_COUNT 1730.</b> As noted in the definitions, the Playback Mode identifies the type of viewing activity, the position identifies the location within the content, and the count identifies the number of devices viewing that second of content in that mode.
0101The reader will observe that for each Playback Mode <b>1710</b> there is a complete list of the Playback Positions <b>1720</b> or viewing seconds when that content was viewed along with the number of devices viewing the content as shown in Playback mode count <b>1730.</b> Thus, the computer has aggregated the Video Program Viewing Detail data <b>150</b> to create this Aggregated Sessionized Linear Viewing Activity (LVA) File <b>220.</b> This output file has value on its own, or it can be loaded to a data store for additional downstream analytics.
0102The reader will also observe that the Linear Viewing data can be aggregated across program airings in order to create a higher level aggregation of viewing activity. This is shown under the title Linear Program 1 Airing 1 and Linear Program 1 Airing 2 Combined. This aggregation, as a non-limiting example, provides insight into viewing of the content across multiple airings.

Alternative Embodiments
0120Although the description above contains much specificity, this should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of several embodiments. As a nonlimiting example, additional qualifiers may be added along with those provided. Additional aggregations can be done using other combinations of these identifiers.
Scope of Viewer Interaction Data Loaded
0121I presently contemplate that the MapReduce Aggregation Engine <b>200</b> will process viewer interaction data for whatever set of viewing activity is provided to it. This may be one Video Program at a time, one hour of the day, a primetime television viewing period, an entire 24 hour day of viewing, a week of viewing, a weekly program schedule time slot, or another time period decided by the analyst. Another embodiment may simply process viewing activity within the context of a single program, or a single advertisement, or some other combination.
Use of Hadoop and MapReduce
0122I presently contemplate that the MapReduce Aggregation Engine <b>200</b> will take advantage of Hadoop MapReduce technology. Another embodiment may load the Video Program Viewing Detail records to a relational database and run various SQL queries to produce results similar to those shown.
Data Explosion Process
0123I presently contemplate that the Data Explosion Process <b>140</b> will generate one record for each second of viewing activity with the field Count_of_1 <b>1390</b> having a value of 1. This method provides flexibility in terms of possible data aggregation, but it does consume more resources to process all the records. In another embodiment logic could be added to the Data Explosion Process <b>140</b> so that various records end up with a count of 2 or 3 or some higher number reflecting that multiple devices were viewing that content. The outcome is that fewer records would be sent into the MapReduce Aggregation Engine <b>200</b> thus reducing the load on the system.
Identifiers for Data
0124I presently contemplate using a combination of numeric and mnemonics for the various fields such as program info, program airing info, channel info, house info, device info, viewer info, geographic info, demographic info, viewing type, video server identifiers, system health info, and other similar fields, but another embodiment could use only numeric values as identifiers with links to reference tables for the descriptions of the numeric identifiers or only mnemonic identifiers.
Data Explosion Process
0125I presently contemplate that the Data Explosion Process <b>140</b> will generate one record for each second of the tuning activity. Another embodiment may generate one record for each video frame of viewing activity. In this case, the playback begin position and playback end position would be replaced by a frame number for each of these fields.
0126Yet another embodiment may generate records at a one minute level with the count being the number of seconds tuned to the content during that minute (in this case there would be 1,440 possible one minute intervals during a 24 hour day).
0127Yet another embodiment may generate records at a 10-second level with the count being the number of seconds tuned to the content during that 10-second interval (in this case there would be 8,640 possible 10-second intervals during a 24 hour day).
Programming Algorithm Scope
0128I presently contemplate executing the algorithms described herein separately in some sequence, but another embodiment could combine multiple simple algorithms into fewer complex algorithms.
Receiving Date and Time Information
0129I presently contemplate receiving all of the date and time values in local time, but another embodiment may provide these in Coordinated Universal Time (UTC time).
General Information
0130I presently contemplate using variables having the data types and field sizes shown, but another embodiment may use variables with different data types and field sizes to accomplish a similar result.
0131I presently contemplate tracking viewing activity at the granularity of one second, but another embodiment may track viewing activity at a finer granularity, perhaps half-second, or tenth-second, or millisecond. Yet another embodiment may receive data at a granularity finer than one second and round to the nearest second for use by the MapReduce Aggregation Engine <b>200.</b>
0132I presently contemplate using record layouts similar to those defined herein, but another embodiment may use a different record layout or record layouts to accomplish a similar result. As a nonlimiting example, another embodiment may use database tables or other objects instead of record layouts similar to those I have defined herein to accomplish a similar result while still working within the spirit and scope of this disclosure.
Implementation Information
0133I presently contemplate using the generic Apache Hadoop distribution, but another embodiment may use a different Hadoop distribution.
0134I presently contemplate using Linux operating system, but another embodiment may use a different operating system.
0135I presently contemplate using the Pig along with the Pig Latin dataflow language, but another embodiment may use Java or Python or some other language alone or in combination with Pig Latin.

Conclusions, Ramifications, and Scope
0144In my previous Applications, I have identified numerous Conclusions, Ramifications, and Scope items. Many of those are similar for this application. The Conclusions, Ramifications, and Scope items from my <patcit id="pcit0008" dnum="US8365212B1"><text>U.S. Patent 8,365,212 B 1 issued on Jan. 29, 2013</text></patcit>, and my <patcit id="pcit0009" dnum="US8365213B1"><text>U.S. Patent 8,365,213 B 1 issued on Jan. 29, 2013</text></patcit>, and my <patcit id="pcit0010" dnum="US36070412A"><text>U.S. Application Ser. No. 13/360,704 filed on Jan. 28, 2012</text></patcit>, and my <patcit id="pcit0011" dnum="US56707312A"><text>U.S. Application Ser. No. 13/567,073 filed on Aug 5, 2012</text></patcit> and my <patcit id="pcit0012" dnum="US74019913A"><text>U.S. Application Ser. No. 13/740,199 filed on Jan 13, 2013</text></patcit> are included herein by reference but not admitted to be prior art.
0145In this discussion below, I will focus on new ramifications introduced by this Application.
0146From the description above, a number of advantages of some embodiments of my MapReduce Aggregation Engine <b>200</b> and its supporting processes become evident: <ul id="ul0009" list-style="none" compact="compact"><li>In this specification I have taught how to measure or analyze video program viewing activity at a second-by-second level using the Hadoop MapReduce framework. This teaching allows measurement of linear program viewing, DVR viewing, and VOD viewing with the ability to understand how the viewer uses "trick plays" when viewing this content. This insight gained from this can be valuable to advertisers, content producers, and content providers. As a non-limiting example, this provides detailed measurements into the amount of fast forward activity that occurs during commercials. Additionally, by teaching how to include numerous identifiers and then aggregate the detailed viewing activity to various combinations of those identifiers, an analyst will now be able to slice-and-dice the data in numerous ways to understand how different content is consumed by various people in various geographic locations.</li></ul>
0147Once the metrics are calculated, the resulting files can be loaded to a database for longitudinal analysis. As a nonlimiting example, the program level metrics can be tracked to identify week- to-week activity such as, for example, total seconds viewed in Play mode. Then the more detailed metrics can provide additional insight into the causes behind the overall trends.
0148The ability to produce these metrics using the Hadoop MapReduce framework provides a new tool for data analysts to use in understanding viewing behavior.
0149This method of using the Hadoop MapReduce framework to calculate second-by-second viewing activity for program based viewing such as linear, DVR, and VOD by aggregating individual viewing records that were created by exploding the viewing period into individual records where each record represents one second of viewing activity is contrary to the teaching of those who work with start time and duration (seconds viewed). Thus I am able to solve problems previously found insolvable when limited to using the existing techniques. I am able to provide metrics that could not be produced using existing techniques.
0150Additionally, I have shown how this teaching is application to online education for use in analyzing video viewing in that context.
Subsequent Usage of the Metrics
0151The metrics produced by the MapReduce Aggregation Engine <b>200</b> readily lend themselves to dimensional analysis using contemporary data warehouse methods. I have reviewed this extensively in my prior applications.
0152The metrics produced by the MapReduce Aggregation Engine <b>200</b> can be loaded to a data warehouse to support additional longitudinal analysis beyond what is done by the Engine <b>200.</b> Thus we can readily envision a myriad of uses for the metrics produced by the MapReduce Aggregation Engine <b>200.</b>
0153Numerous additional metrics can readily be identified by those skilled in the art. Additionally, numerous additional uses for the metrics identified herein will be readily evident to those skilled in the art.
Summary
0154In accordance with one embodiment, I have disclosed a computer-implemented method of using video program viewing activity data as input to an aggregation engine built on the Hadoop MapReduce framework which calculates second-by-second video viewing activity for Linear, DVR, and VOD program level viewing including measuring trick play activity with results aggregated to the analyst's choice of program, program airing, channel, house attributes, device attributes, geographic area, demographic attributes, viewing date, or any combination of these fields, for each second of program content represented in the video program viewing data. The source data may be extracted from a database defined according to the Cable Television Laboratories, Inc. Media Measurement Data Model defined in "Audience Data Measurement Specification" as "OpenCable™ Specifications, Audience Measurement, Audience Measurement Data Specification" document OC-SP-AMD-101-130502 or any similar format. These metrics provide detailed data needed to calculate information on customer viewing behavior that can drive business decisions for service providers, advertisers, and content producers. The ability to use the Hadoop MapReduce framework to aggregate this data will meet pressing needs for detailed audience viewership information that is not presently available and thus the metrics will be of great value to the industry.
