[Technical field to which the invention belongs]

The present invention provides a video signal used in an editing system, also called an authoring system, for producing media such as a video CD that is compressed and encoded with high efficiency and recorded in a format capable of real-time reproduction of moving image data. It relates to a video information editing device for editing and encoding.

[Conventional technology]

FIG. 5 is a conceptual diagram of a video information authoring system (in a broad sense) related to the conventional technology. The conventional authoring system is broadly composed of director work W1, post-production work (post-production work) W2, and authoring work W3. These three tasks are generally handled by different specialists.

【0003】

The plurality of video materials 11a, 11b, 11c ... Are tape-shaped recording media that record unedited video information in a commercial digital VTR used for broadcasting, for example. In many cases, each video material contains different scenes at random. In the director work W1, the primary editing machine 12 for business use is used to determine the necessary scene cuts for each video material 11a, 11b, 11c .... In addition, we will also decide what kind of effect processing will be applied to the part where the selected adjacent cuts are connected. The reproduced signal from the video material includes the video signal and the time code for each field or frame. Timecode is used to specify the beginning and end of the cut to be cut. For effect processing, crossfade (gradually blurring the end of the preceding cut and gradually clarifying the beginning of the succeeding cut), wipe (moving laterally to gradually reduce the area at the end of the preceding cut as if pulling the curtain). Roll (move laterally to gradually increase the area at the beginning of the subsequent cut), roll (turn the pages of the book to round the end of the preceding cut and shrink it to make the beginning of the succeeding cut a rounded mark of the preceding cut) There are various things such as mosaic (revealing the preceding cut in a mosaic manner while erasing the preceding cut in a mosaic manner). The editing work in the director work W1 is called rough editing, and is repeated by trial and error. In other words, cuts that were considered necessary at the previous point in time are discarded at a later point in time, and cuts that were not needed at a later point in time are incorporated later. You can also change the order of each cut. When performing rough editing for a video CD that records a movie (movie) or karaoke, select up to 74 minutes of video information.

【0004】

By such rough editing, in the primary editing machine 12, editing information (EDL: Edit Decision) of which cut of which video material is connected in which order and by what effect processing is performed. List) is obtained. That is, the editing information (EDL) including the identifier of the selected video material, the editing point information by the in and out time code of the selected cut, the effect information, and the like can be obtained. In the middle stage of rough editing, the editing information in the middle stage exists, and based on the editing information, the necessary cuts are played back from each video material at the timing indicated by the editing point information, and the rough editing result 13 is displayed on the monitor. While displaying it, check whether it fits the scenario. The scenario itself may be changed, and rough editing is performed by trial and error. The rough-edited result 13 is often the one in which the rough-edited content is recorded on a tape, but it may also be directly reproduced from the video material 11a, 11b, 11c ... Finally, the completed editing information (EDL) 14 will be obtained. This edited information is recorded on a recording medium 15 such as a floppy disk. This completes the director work W1. The primary editing machine 12 has relatively low initial cost and running cost (initial cost is several million yen).

【0005】

Next, the recording medium 15 on which the editing information 14 including the above-mentioned editing point information and the effect information is recorded and the original video material 11a, 11b, 11c ... are brought to the post-production company to post-production. Perform work W2. For post-production work W2, we use a secondary editing machine 16 whose initial cost and running cost are extremely high, which is incomparable to that of the primary editing machine 12 for director work W1 (By the way, the initial cost is hundreds of millions of yen. , The running cost is on the order of one million yen / hour). The primary editing machine 12 and the secondary editing machine 16 have almost the same functions, but the secondary editing machine 16 is overwhelmingly more accurate in terms of editing accuracy. In particular, the accuracy of effect processing is extremely high. Therefore, it is so expensive.

【0006】

In the post-production work W2, the secondary editing machine 16 starts from each video material 11a, 11b, 11c ... Based on the editing information (editing point information + effect information) 14 recorded on the set recording medium 15. The complete package material 17 is produced by cutting out the corresponding cut portion of the video signal including the time code at a predetermined timing and connecting the cut parts in sequence while inserting the effect processing. The specific state of the editing work by the secondary editing machine 16 will be described below with reference to FIG.

【0007】

For example, the editing information 14 recorded on the recording medium 15 cuts out a cut C1 starting from the editing point time code IN1 (cut IN point) and ending with the editing point time code OUT1 (cut OUT point) from the video material 11a, and the same video material. Cut out the cut C2 starting from 11a and ending with the editing point time code IN2, cutting out the cut C3 starting from the editing point time code IN3 and ending with the editing point time code OUT3 from another video material 11b, and yet another video. Cut out the cut C4 that starts with the edit point time code IN4 and ends with the edit point time code OUT4 from the material 11c, and cuts out the cut C5 that starts with the edit point time code IN5 and ends with the edit point time code OUT5 from the video material 11c, and after the cut C1. Cut C2 is connected by inserting the effect E1 between them, cut C3 is inserted after the cut C2 and the effect E2 is inserted between the two, and the cut C4 is inserted after the cut C3 and the effect E3 is inserted between the two. It is assumed that the cut C5 is connected after the cut C4 without inserting an effect.

【0008】

First, in order to cut out the cut C1, the secondary editing machine 16 controls the playback device of the video material 11a, runs the video material 11a at high speed, stops it at the editing point time code IN1, and records the complete package material 17. And the playback device of the video material 11a are synchronously controlled, and the cut C1 of the video material 11a is dubbed to the original tape of the complete package material 17. Editing point The recording device and playback device are stopped at the time code OUT1, and the recording device slightly rewinds the original tape of the complete package material 17, while controlling the playback device to cut out the next cut C2, the video material 11a Run at high speed and stop at edit point time code IN2. In the same manner as described above, the recording device and the playback device are synchronously controlled to start dubbing to the complete package material 17 from the edit point time code IN2 of the cut C2 of the video material 11a, and the effect E1 is inserted at the initial stage of this start. Editing point The recording device and playback device are stopped at the time code OUT2, and the recording device rewinds the complete package material 17. Next, in order to cut out another cut C3 of the video material 11b, the playback device of the video material 11b is controlled to run the video material 11b at high speed and stopped at the edit point time code IN3, and the recording device and the playback device are used. Is synchronously controlled to start dubbing to the complete package material 17 from the edit point time code IN3 of the cut C3 of the video material 11b, and the effect E2 is inserted at the initial stage of this start. Similarly, in order to cut out the cut C4 of yet another video material 11c, the playback device of the video material 11c is controlled to run the video material 11c at high speed and stopped at the edit point time code IN4, and the recording device and the playback device are used. Is synchronously controlled to start dubbing to the complete package material 17 from the edit point time code IN4 of the cut C4 of the video material 11c, and the effect E3 is inserted at the initial stage of this start. Furthermore, in order to cut out the cut C5 of the video material 11c, the playback device of the video material 11c is controlled to run the video material 11c at high speed and stop at the edit point time code IN5, and the recording device and the playback device are synchronously controlled. Editing point tie of cut C5 of video material 11c Start dubbing for complete package material 17 from Mucord IN5. At this time, the effect is not inserted. Edit point Stop the recording device and playback device at the time code OUT5. By executing the above editing processes one after another, a complete package material 17 (tape-shaped recording medium) in which a video signal of up to 74 minutes is recorded for a video CD is completed.

【0009】

Next, the complete package material 17 is brought to the authoring company and the authoring work W3 is performed. Authoring is also called premastering. In the authoring work W3, the encoder 18 is used to compress and encode the video signal reproduced from the complete package material 17 in accordance with, for example, MPEG (Moving Picture Coding Experts Group), which is an international standard for image compression, and video CD. Generates encoded data 19 for recording in. The coded data 19 is recorded on a video CD by mastering.

[Problems to be Solved by the Invention]

As described above, in the authoring system according to the conventional technique, the post-production work W2 is interposed between the director work W1 and the authoring work W3, and the secondary editing machine 16 used in the post-production work W2 Since the initial cost and the running cost are extremely high, it has been forced to take a very high cost to produce the complete package material 17. In addition, even if a post-production work contractor is requested to process, if a large number of requests are received first, the process may be awaited and a large amount of time may be required to obtain the complete package material 17.

【0011】

The present invention was devised in view of such circumstances, and eliminates the need for post-production intervention, which requires a great deal of cost and time, and is equivalent to a complete package that should be finally compressed and encoded in the authoring work. It is an object of the present invention to provide a video information editing device capable of obtaining a signal economically in terms of both cost and time.

【0021】

Hereinafter, specific embodiments of the video information editing device according to the present invention will be described in detail with reference to the drawings.

【0022】

[Embodiment 1] The first embodiment corresponds to claim 2. FIG. 1 is a block diagram showing a configuration of an authoring system using the video information editing device according to the first embodiment of the present invention. Codes 11 to 15 are the same as the configuration shown in Fig. 5. Briefly, 11a, 11b, 11c ... are unedited video information in a commercial VTR, 12 is a low-cost primary editing machine, and 13 is a low-cost primary editing machine. Rough editing results for display on the monitor, 14 is the editing information (EDL) including the finally determined editing point information (video material identifier / editing point time code) and effect information as a result of the rough editing, 15 Is a recording medium such as a floppy disk on which the editing information 14 is recorded, and W1 indicates the director work.

【0023】

Further, in FIG. 1, 100 is a video information editing device according to the first embodiment of the present invention, and the video information editing device 100 is composed of an editing information input means 21, a video input means 31, and an effect processing means 41. ing. The editing information input means 21 inputs the editing information 14 from the recording medium 15 on which the editing information (EDL) 14 including the editing point information and the effect information is recorded, and the editing point information (video material identifier) of the editing information 14 is input. The edit point time code) is output to the video input means 31, and the edit point information and the effect information are output to the effect processing means 41. The video input means 31 is composed of an input control means 32, individual video signal input lines 33a, 33b, 33c ..., a video signal selection means 34, and an output buffer means 35. The input control means 32 uses the video material identifiers in the edit point information as the video material 11a, 11b, 11c ... The playback device (not shown) in which the video material to be played is set is started, and the playback device is driven and controlled based on the edit point time code from the cut IN point of the cut to be cut out from the video material. The video signal selection means 34 is connected to the video signal input line 33a when the video material 11a is being played, and the video signal selection means 34 is connected when the video material 11b is being played. The video signal selection means 34 is controlled based on the video material identifier so as to connect to the video signal input line 33b and connect the video signal selection means 34 to the video signal input line 33c when the video material 11c is being played. is there. The output buffer means 35 is for temporarily storing a digital video signal including a time code reproduced from any video material selected by the video signal selection means 34. The effect processing means 41 is composed of an effect control means 42 and an effect execution means 43. The effect control means 42 inputs the edit point information and the effect information from the edit information input means 21, and compares the time code of the video signal output from the output buffer means 35 of the video input means 31 with the time code of the edit point information. , When the video signal input from the output buffer means 35 by the effect executing means 43 is a video signal other than the editing point where the effect processing should be executed, the video signal is directly used as the encoder 18 without activating the effect executing means 43. As a result of comparing the time code of the video signal with the time code of the edit point information, the video signal input by the effect execution means 43 should execute the effect processing. When it is a point video signal, effect information is given to the effect execution means 43, and the video signal input to the effect execution means 43 is subjected to effect processing according to the effect information and output to the encoder 18. It is configured to control the effect execution means 43. Encoder 18 The video signal input from the effect executing means 43 is compressed and encoded according to, for example, MPEG, and encoded data 19 for recording on a video CD is generated. W3 shows authoring work. In this authoring work W3, the original tape of the complete package material 17 as in the case of the conventional technique is not required. The video signal 51 output from the effect executing means 43 corresponds to a complete package. In other words, the post-production work W2 in the case of the conventional technology is omitted.

【0024】

The operation in the director work W1 is the same as in the case of the conventional technology, and a recording medium such as a floppy disk on which the editing information (EDL) 14 consisting of the editing point information (video material identifier / editing point time code) and the effect information is recorded. You get 15.

【0025】

Next, the operation in the authoring work W3, that is, the operation of the video information editing device 100 configured as described above will be described. The unedited video materials 11a, 11b, 11c ... used in the director work W1 and the recording medium 15 on which the editing information 14 obtained by the director work W1 is recorded are brought in. Each video material 11a, 11b, 11c ... is set in a playback device (not shown), and the recording medium 15 is set in the editing information input means 21. The editing information (EDL) 14 including the editing point information (video material identifier / editing point time code) and effect information recorded on the recording medium 15 is read into the editing information input means 21. Then, the editing information input means 21 transfers the editing point information (video material identifier / editing point time code) of the read editing information 14 to the input control means 32 in the video input means 31, while the editing point information and the effect information are combined. Is transferred to the effect control means 42 in the effect processing means 41.

【0026】

In the video input means 31, the input control means 32 is a playback device (shown) in which the video material to be reproduced among the video materials 11a, 11b, 11c ... is set based on the video material identifier in the edit point information. The playback device is driven and controlled based on the edit point time code to play back from the cut IN point to the cut OUT point of the cut to be cut out from the video material. Here, it is assumed that, for example, the video material 11a is selected based on the video material identifier. That is, the input control means 32 first detects the time code from the video material 11a while traveling the selected video material 11a at high speed, compares the detected time code with the cut IN point of the edit point time code, and then compares the detected time code with the cut IN point of the edit point time code. When the detected time code matches the cut IN point, the running of the video material 11a is temporarily stopped, the input control means 32 controls the video signal selection means 34, and the video material 11a whose selection actuator is selected is connected. It is connected to the video signal input line 33a, and then the playback device in which the selected video material 11a is set is driven to start normal playback from the cut IN point. The digital video signal accompanied by the time code input by the normal reproduction is temporarily stored in the output buffer means 35 one after another. During the input of the reproduced video signal, the input control means 32 monitors the time code of the video signal and compares it with the cut OUT point of the edit point time code. When the time code of the video signal matches the cut OUT point, the input control means 32 stops the reproduction from the video material 11a and turns off the selection actuator of the video signal selection means 34. The above operation is repeated based on the video material identifier and the edit point time code included in the edit point information. That is, the video materials are sequentially selected, the selected video materials are sequentially reproduced from the cut IN point to the cut OUT point, and the reproduced digital video signal is stored in the output buffer means 35 together with the time code. To go.

【0027】

When the output buffer means 35 stores a predetermined amount of video signal data, the input control means 32 gives an activation signal to the effect control means 42 in the effect processing means 41 and gives a read command to the output buffer means 35. At this time, the effect control means 42 has already input the edit point information and the effect information from the edit information input means 21. The effect control means 42 compares the time code output in synchronization with the video signal from the output buffer means 35 with the edit point time code, and the time code of the video signal is a video signal other than the edit point where the effect processing should be executed. When is, the effect execution means 43 is controlled so that the video signal is output to the encoder 18 as it is without activating the effect execution means 43, and the result of comparison between the time code of the video signal and the edit point time code is the effect. When the video signal input by the execution means 43 is the video signal of the editing point at which the effect processing should be executed, the effect information is given to the effect execution means 43 with respect to the video signal input to the effect execution means 43. The effect execution means 43 is controlled so that the effect processing according to the effect information is executed and output to the encoder 18. The effect executing means 43 outputs a video signal 51 equivalent to a complete package to the encoder 18.

【0028】

The encoder 18 compresses and encodes the video signal 51 input from the effect executing means 43 in accordance with, for example, MPEG, and generates encoded data 19 for recording on a video CD or the like.

【0029】

As described above, according to the video information editing device 100 according to the first embodiment, the cuts to be edited required are sequentially read from the video materials 11a, 11b, 11c ... You can connect matching cuts by applying effect processing between them. Then, the post-production work W2 required in the conventional technology is omitted, the video signal 51 equivalent to the complete package is generated, output to the encoder 18, and the encoded data 19 for recording on the video CD or the like in the encoder 18 is stored. Can be generated. The configuration of the video information editing device 100 is relatively simple, and the initial cost and running cost are significantly higher than those of the extremely high-cost secondary editing machine 16 used for the post-production work W2 of the conventional technology. Can be reduced. Moreover, since the need for waiting time is eliminated, the time cost can be reduced.

【0030】

The director work W1 contractor and the authoring work W3 contractor are generally separate, but may be carried out by the same contractor. In this case, in transmitting the editing information 14 from the director work W1 to the authoring work W3, instead of using the recording medium 15, the primary editing machine 12 and the editing information input means 21 of the video information editing device 100 are connected by a line to perform data.

[Effect of the invention]

According to the video information editing device according to the present invention, an editing information input means for reading editing information consisting of editing point information and effect information, and a time code from an unedited video material from which the editing information is obtained. A video input means that selectively captures a digital video signal and a time code of a cut to be edited from the video material based on a comparison with edit point information acquired from the edit information input means, and an output from the video input means. An effect processing means that processes a digital video signal with a time code based on the edit point information and effect information acquired from the edit information input means, and a digital video signal output from the effect processing means are input. Since it is composed of an encoder that compresses and encodes to generate encoded data, the cuts to be edited required are sequentially read from the video material, and the read adjacent cuts are subjected to effect processing between the two. By connecting in the applied state, it is possible to obtain a video signal equivalent to a complete package to be input to the encoder for final compression coding in the authoring work, and further, encoded data for recording on a video CD or the like in the encoder. However, the configuration required for this is relatively simple, eliminating the costly and time-consuming post-production intervention required by conventional technology, both in terms of cost and time. It is possible to achieve a significant economic improvement.
