It should be appreciated that while the various embodiments of the current principles described above relate to the use of WAV files as one type of digital sound file to which the current principles can be applied, it is to be understood. appreciated that the current principles are not limited only to the use of WAV files and, thus, other types of digital sound files can also be used, while maintaining the spirit of current principles. Preferably, the type of digital sound file used is a lossless type of digital sound file, so that the original content included in the media file from which the sound file is created can be preserved in its entirety. Thus, in the case of WAV files, while a ηοη-PCM modulation technique can be employed to produce such WAV files, it is

<img file="MA31783B1_D0002.tif" />

ΜΑ 31783Β1 is preferred to employ pulse code modulation (PCM) modulation which can be configured to provide such lossless capability.

It is to be further appreciated that as used above, the term multimedia refers to content or a file which includes at least two different types of media which are directly perceptible to a user (such as video and / or data. which is seen and the audio against which is heard, for example, data (hereinafter referred to as other data) such as, but not limited to, side data which is not seen by a user, but rather can process data that is seen by a user). While it should also be appreciated that the media file can include such other data and, moreover, that current principles are also readily capable of processing such other data in the above-described processes of transformation and reconstruction, it should be appreciated that the multi aspect of the term multimedia as used above with respect to a multimedia file is nevertheless directed to the transformation of at least two different types of data which are directly perceivable to a user. Therefore, the current principles are particularly suitable for films, for example, as represented by files of MPEG-2 and MPEG-4 AVC, since such films will have a visual component and an audio component in the case of non-films. -silent, where the two components are directly perceptible to a user. Advertisements having a visual component and an audio component also particularly suitable for use according to current principles.

As stated above, current principles are directed to methods and systems for the transfer of multimedia content using an existing digital sound transfer protocol. It should be appreciated that the folder of the multimedia content to be transferred can originally be of any shape.

For example, a video clip can be represented by, but is not limited to, one of the following file formats: audio video interleave (AVI); the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Experts Group-l (MPEG-1) Standard; the ISO / IEC MPEG-2 Standard, the International Telecommunication Union, Telecommunication Sector (ΐτυ-τ) Η.263 Recommendation; the ISO / IEC MPEG-4 Part 2 Advanced Video Coding (AVC) Standard (hereinafter the MPEG-4 Part 2 Standard); the ISO / IEC MPEG-4 Part 10 Advanced Video Coding (AVC) standard / ΐτυ-τ Η.264 recommendation (hereinafter the MPEG-4 AVC standard); And so on

An image may be represented by, but is not limited to, any of the following file formats: Common Photographic Expert Group (JPEG); JPG; JPE; JFIF; JIF; bitmap (BMP); tagged image file format (TIFF); tagged electronic image / photograph file format (TIFF / EP); graphics interchange format (GIF); portable network graphics (PNG); And so on.

Data can be represented by, but is not limited to, any of the following file formats: text; RAR; portable document format (PDF); ZIP; ASCII, and so on.

An illustrative overview of an exemplary embodiment of the current principles will now be described. However, it is to be appreciated that, given the teachings of the principles

MY

31783Β1 provided above, one of ordinary person skilled in the art and allied arts will contemplate this and various other embodiments and variations thereof, while maintaining the spirit of the present principles.

In the embodiment, the media content is entered into a binary conversion process which converts the media content to corresponding, representative binary values.

The binary data is then transformed into a digital sound file using a transformation process as described in detail above. In one embodiment, the sound file cannot be, but be limited to, a WAV folder. In one embodiment, the WAV record has a frequency represented by a variable hereinafter referred to as the FS (with the unit of measure in it, for example. Hertz) and a number of bits represented by a variable hereinafter referred to as NBITS. The WAV file can be, for example, a WAV file using a lossless modulation format, a WAV file using a lossless modulation format (for example, Pulse Coded Modulation (PCM)), and so on. after.

It should be appreciated that the transformation of media file into sound folder is the same for all types of media files, that is, the transformation ignores the nature and structure of media files. As a result, a JPEG, MPEG-2 and RAR file is read in the same way in order to obtain representative binary values. In particular, in the case of files corresponding to MPEG-2 standard or MPEG-4 AVC standard, the synchronization between the visual part and the audio part is not changed during transformation, but rather preserved.

The WAV file, which includes the digital sounds corresponding to the above multimedia content, will be transferred to the destination with an existing protocol used to carry the digital sounds.

When the WAV file having digital sounds is received, the media content can be recovered intact using a recovery process as described in more detail above.

In one embodiment, the quality of the media content that is retrieved is the same as the quality of the media content before binary conversion, that is, one or more embodiments of the current principles provide a lossless manner. transform, transfer, and reconstruct multimedia content. If the course, such absence of loss relates to aspects of current principles regarding the transformation and reconstruction of multimedia content with respect to a sound file, and not to any compression initially applied to the content. multimedia as, for example, when the multimedia content which has entered a system according to current principles is already compressed as in the case of a file encoded according to the MPEG-4 AVC standard.

- fmt.Data Coding Format = 1 if NBITS &lt;32 = 3 if NBITS = 32

- fint.Number ofChannels = channels

- fint.Number of Sample Per Second = FS

- fmt. Average Transfer Rate = channels * bytes per sample: FS

- fmt.Block Alignment = channels * bytes per samples

- mt. Number of Bits Per Sample = NBITS

In step 640, the binary data included in matrix Y is written to the media content file (opened in step 635).

It should be appreciated that embodiments of the present principles can be readily performed to achieve the intended result. For example, consider the following illustration example. A visual order encoded using MPEG-4 and having a file size of 227,562 KBs, with a resolution of 640x480 and a duration of 44 minutes is transformed into a WAV file (e.g., according to step 410 of method 400 of FIG. 4. and / or steps 505-570 of method 500 of FIG. 5) in less than 50 seconds. The reciprocal process (eg, according to step 430 of method 400 of FIG. 4 and / or steps 605-640 of method 600 of Fig. 6) also takes no more than 50 seconds. These results are obtained with a PC of the following type, with the following characteristics: TOSHIBA MSAT010AIV10 with 1 gigabyte of RAM memory and an INTEL CENTRINO DUO Τ2400 processor having a processor speed of 1.83GHz. The CPU time for the transformation depends on the characteristics of the video to be processed.

As is evident to an ordinary person skilled in this art and related arts, the present principles have wide applicability in many fields. For example, the current principles can be employed, but are not limited to the following applications: mobile telephony; satellite television transmission; And so on.

An application of current principles related to mobile telephony will now be described. It should be appreciated that FIGs. 2 and 3 illustrate examples of systems involving mobile telephony.

As noted above, the second generation of Global System for Mobile Communications (GSM) in Europe and Personal Communications Service (PCS) in the United States are both limits in their possibilities with regard to the transfer of content. multimedia including, for example, visual content. Additionally, while Universal Mobile Telecommunications System (UMTS) provides a solution for the transfer of multimedia content using a telephony network, UMTS also includes at least one significant drawback. Namely, the cost is very high for each operator and, therefore, for the customer as well.

Advantageously, the current principles provide a solution to the transfer of multimedia content which is precise and less complex than prior art approaches, while thus doing very at a low cost.

In a mobile telephony embodiment, two new functionalities can be added in the existing mobile telephone, such as based on, but not limited to, for example, GSM1

PCS, and / or UMTS. These two new features include the transformation of multimedia content into digital noise, and the corresponding reciprocal process.

The aim of the first transformation process in the Handy is to transform a visual order, for example, captured by an integrated camera of the Handy, into digital sound. This same digital sound will be transported to another mobile phone using an existing protocol of GSM, PCS, UMTS, and so on.

The mobile operator could also use the first transformation process to turn a movie into digital sound, and then send that sound to the customer's mobile phone.

The object of the second transformation process is to re-transform the received digital sounds, as included in the received file (e.g. a WAV file), into, for example, a visual order or in a movie from a mobile phone operator or another mobile phone user.

Advantageously, the current principles provide a solution to the saturation problem of the prior art and to the scarcity of frequencies available for use in the transfer of multimedia content over a telephone network. Embodiments of the current principles allow a mobile telephone operator to use its usual frequency (i.e., the frequency typically reserved for voice communications) or any other frequency to carry multimedia content. , with the additional cost not essentially significant.

Thus, embodiments of the current principles will be able to utilize existing equipment and will not suffer from the current problem of scarcity of available frequencies. Moreover, the embodiments of the current principles will contribute to the protection of the environment as an additional relay station will not have to be manufactured and maintained to support the device of transferring multimedia content over a telephone network. mobile according to current principles.

Moreover, in the case of a sector without a network of telephony or satellite coverage, the current principles take into account the transfer of multimedia content by radio waves and the subsequent reconstruction of such content, for example, d 'a display screen and / or one or more loudspeakers.

It should be appreciated that the current principles can be applied in connection with any network capable of carrying digital sounds. A movie recording in the high definition will be able to transit at a frequency other than that specific for the transmission of the high definition media content, while keeping the high definition media content intact at the wrong side.

It is yet to be appreciated that a significant advantage is obtained by employing a digital sound file to transfer a multimedia file. For example, the use of a digital sound file allows the digital sound file and, therefore, the multimedia content represents thereby, to be transmitted and received using a protocol which is generally reserved for voice communications. and which is the popular protocol used in telephony applications. In this way, the use of a separate protocol (dedicated for multimedia transmissions) and, in some cases, a separate channel (dedicated for multimedia transmissions), can be avoided.
