Description

  The present invention relates to a continuous reproduction system.

Conventionally, a method of switching and reproducing a plurality of moving image files using two decoders has been proposed.
JP 2001-177829 A

  However, in the above method, a plurality of moving image files are simply decoded continuously and the display is switched, and special effects such as wipe and overlap cannot be displayed when the display is switched.

  In view of such circumstances, the present invention proposes a continuous playback system that performs effect processing using image frame data for an arbitrary plurality of frames and performs effect processing so that the two files are naturally switched. . In order to realize such a continuous reproduction system, it is characterized by adopting a concept of a reproduction information file. While reproducing different types of data included in the moving image file for each type, the image frame data generated based on the reproduction information file is accumulated in a memory managed by the operation management unit and effect processing is performed. At this time, the moving image file reproduction processing unit may notify the operation management unit of the elapsed reproduction time during the reproduction processing of the moving image file. Further, the reproduction information management unit may notify the operation management unit of an analysis result obtained by analyzing the reproduction information file read by the reproduction information file processing unit. In addition, the effect processing unit is notified of the effect degree information, and the effect process is performed based on the degree information, the image data for a plurality of frames used for the effect process, and the effect type information. Sometimes it is done.

  Furthermore, the storage unit may be inside the terminal equipped with the continuous playback system, on a peripheral device outside the terminal, or on an external network. When streaming video files, the second and subsequent videos that are continuously played back are used. Effect processing may be performed during file buffering. In addition, when streaming playback of a moving image file, it may be specified that image data for a plurality of frames used for effect processing is generated on the client side or the server side.

  As described above, the continuous playback system according to any one or more of the inventions of the present invention uses the effect effect based on the playback information file when switching between playback of two moving image files, so that the user can Thus, it is possible to provide a variety of image display without the need for the user. In addition, since the effect of the effect based on the playback information file can be used to alleviate rapid image switching, an effect of promoting the playback and viewing of a large number of moving image files to the user can be expected. Furthermore, since information related to playback control can be described in the playback information file, it is possible to arbitrarily set the effect type between videos, the timing for effecting, the display period, etc. Is expensive.

  Also, by managing the timing of creating image frame data based on the description of the playback information file, it is possible to display the effect-processed image while decoding the two moving images, and various image switching effects can be achieved. Obtainable. On the other hand, if the playback elapsed time is notified, the elapsed playback time can be compared with the effect start time information contained in the playback information file, so it is immediately determined whether effect processing needs to be started. Can respond. On the other hand, if the analysis result of the reproduction information file read by the reproduction information file processing unit is notified to the operation management unit, various types of effect processing can be immediately handled according to the analysis result. These are particularly effective when information related to playback control is described in the playback information file and the timing for effecting is arbitrarily set. In addition, by receiving the notification of the degree of application, a natural effect effect can be applied without being biased.

  Furthermore, when the storage unit is inside a terminal equipped with a continuous reproduction system, it is advantageous that a moving image file and a reproduction information file can be accessed immediately. On the other hand, when the storage unit is on a peripheral device outside the terminal or on an external network, it is advantageous that a large file can be stored. Furthermore, even when streaming playback is performed, if effect processing is performed during buffering of a moving image file, it can be expected that the effect processing is performed smoothly. In addition, when generating the image data to be used for effect processing by specifying the client side or the server side, the image data generation processing can be distributed, so the processing load on the terminal device and the continuous playback system as a whole can be reduced. It has the effect that it can be reduced.

  The best mode for carrying out each invention will be described below. Note that the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the spirit of the present invention.

  << Embodiment 1 >>

  <Embodiment 1: Overview> Embodiment 1 will be described. The present embodiment is a continuous reproduction system that performs effect processing using image frame data for an arbitrary plurality of frames.

  FIG. 1 shows an example of the concept of this embodiment. The figure shows a scene in which the moving image files M and M + 1 are continuously effect-reproduced using the image frame data of the first frame of the moving image file M + 1. Here, the moving image file M shows a situation where dandelion fluff is scattered, and the moving image file M + 1 shows a situation where chicks crawl from eggs. If the effect processing is not performed after the movie file M when the movie file M + 1 is played back, the egg that is the first scene of the movie file M + 1 immediately after the dandelion scene with no fluff that is the final scene of the movie file M The scene where the crack begins to crack is played back.

  However, here, a reproduction information file describing control information for continuously reproducing the moving image files M and M + 1 is prepared, and effect reproduction as shown in the reproduction information file is performed. The reproduction information file includes an image frame data generation interval indicating a time interval for generating one frame of image frame data from the moving image file, moving image information indicating an effect start time, period, type, and the like. . Now, the image frame data generation interval is 30 ms, and one frame of image frame data can be generated every 30 ms from the moving image file M. Here, the four frames (120 ms) from the end of the moving image file M are called F1 to F4, and the three frames (90 ms) from the beginning of the moving image file M + 1 are called F'1 to F'3. I will do it.

  According to the moving image information of the moving image file M, the effect reproduction of the slide effect indicated by the effect type is performed for 90 ms that is the effect period from the time point of the frame F2 that is the effect start time (after 3S has elapsed from the beginning). In the figure, a mode is shown in which F′1, which is the first frame of the image file M + 1, slides from the right side so as to gradually overlap. After the end of the effect period, the moving image file M + 1 is played back. At this time, effect reproduction as shown in the reproduction information file for the moving image file M + 1 is performed, but is omitted here.

  <Embodiment 1: Configuration> FIG. 2 shows an example of functional blocks in the present embodiment. The “continuous playback system” (0202) of this embodiment shown in FIG. 2 includes a “storage unit” (0201), a “moving image file playback processing unit” (0202), and a “playback information file processing unit” (0203). , “Effect processing section” (0204) and “Operation management section” (0205).

  Each unit, which is a component of the present invention, is configured by either hardware, software, or both hardware and software. For example, as an example for realizing these, when a computer is used, hardware composed of a CPU, a memory, a bus, an interface, a peripheral device, and the like and software executable on these hardware are listed. be able to. Specifically, the functions of the respective units are realized by sequentially executing the programs developed on the memory, by processing, storing, and outputting data on the memory and data input through the interface. (The same applies throughout this specification.)

  The “continuous playback system” (0200) is a system that plays back moving image data.

  The “storage unit” (0201) stores a moving image file and a reproduction information file. The “moving image file” is configured by one or a combination of two or more of a plurality of different types of data such as image data, audio data, and telop data.

  The “playback information file” is a file describing control information related to playback processing including the playback position of a moving image file. The reproduction information file describes information relating to effect processing between the moving image file to be continuously reproduced and the preceding and subsequent moving image files. As shown in FIG. 3, the reproduction information file includes image frame data generation timing information indicating timing for generating image frame data used for effect processing, and moving image information corresponding to the number of moving image files. Here, the playback information file has a structure composed of single image frame data generation timing information for a plurality of video files. However, the present invention is not necessarily limited to this, and individual video frame data generation for each video file is possible. There may be a configuration having timing information. If the underlying image frame data does not exist, such as when a moving image file is not decoded every timing (for example, 30 ms) indicated by the image frame data generation timing information, the latest image frame data that currently exists is used. Image frame data used for effect processing is generated.

  As shown in FIG. 3A, the moving image information includes moving image file name information to be reproduced, time information for starting reproduction, effect start time information indicating the time for starting effect processing, and how long the effect processing is performed. There may be included effect period information indicating whether to perform, other effect types indicating the type of effect, and the like. The effect type corresponds to dissolve, fade, slide, turn, etc., as will be described later. As another application example, as shown in FIG. 3B, use frame information (for example, designation of F′1 or the like, which is information for specifying which frame is used for effect processing) is used. Note that there may be a dedicated frame used for the effect.) And playback order information that is information indicating the playback order of the operation file (for example, the order of the moving image files M and M + 1 can be specified). And so on. In addition, the degree-of-change change rate information, which is information indicating the change state of the degree of effect, may be included. As shown in FIG. 3C, the degree-of-appearance change rate information is a standard indicating how the effect is applied between the moving image files M and M + 1, for example. In the case of (1), it is recognized that the moving image file M changes in a proportional manner from M + 1 (the degree of change rate information is 50%). On the other hand, in the case of (2), the moving image file M is preferentially changed (the degree of change rate information is 90%), and in the case of (3), the moving image file M + 1 is preferentially changed. (The degree-of-change information is 10%).

  The “moving image file reproduction processing unit” (0202) performs reproduction processing of the moving image file. The moving image file stored in the storage unit (0201) is continuously reproduced according to the control from the operation management unit (0205). At this time, the reproduction order of the moving image file may be controlled from the operation management unit.

  The “reproduction information file processing unit” (0203) reads / writes and analyzes the reproduction information file. The reproduction information file is a file describing control information related to reproduction processing, and information on what kind of effect processing should be performed when reproducing a moving image file by reading the reproduction information file from the storage unit (0201) and analyzing it. Is obtained. This information is used when effect processing is performed in the effect processing unit (0204). Note that the reproduction information file is not only stored in the storage unit in advance, but may be sequentially generated by the GUI according to the user's operation. When changing or adding effect effects, it may be realized by sequentially generating corrected playback information files according to user operations, or correcting to playback information files stored in the storage unit in advance. You may implement | achieve by writing. The reproduction information file can be corrected, for example, for individual information such as the effect period and the effect type, or can be added or corrected in units of moving image information.

  The “effect processing unit” (0204) performs effect processing using image frame data for an arbitrary plurality of frames. Playback is performed using the effect identified by the effect type using image frame data for a plurality of arbitrary frames during the effect period from the effect start time of the movie file indicated by the movie file name included in the playback information file. At this time, in the example shown in FIG. 1, only F′1, which is the first frame of the moving image file M + 1 to be reproduced next, is used as the image frame data for an arbitrary plurality of frames. In addition, the number of frames is not limited to this.

  Note that the effect processing includes dissolve, fade, slide, turn, and the like. “Dissolve” refers to an image display method for gradually switching the image of the moving image file M to the image of the next moving image file M + 1. The dissolve can be displayed in various ways, for example, by a switching method in which images are diffused and collected in a granular manner, or by conversion of color and brightness. “Fade” refers to an image display method in which the image of the next moving image file M + 1 is displayed as the image of the moving image file M disappears. Fade can be displayed in various ways, such as by overlapping images, or by converting colors and brightness. “Slide” refers to an image display method in which the image of the next moving image file M + 1 slides with respect to the image of the moving image file M. When the image of the moving image file M + 1 slides, whether the pre-selection icon image is pushed out or whether it overlaps with the moving image file M, or the direction in which the moving image file M + 1 slides. Various displays are possible depending on the speed. “Turn” refers to an image display method in which the image of the moving image file M is rotated and the image of the moving image file M + 1 is displayed. The turn can be displayed in various ways depending on the direction of rotation, angle, and speed.

  The “operation management unit” (0205) controls the moving image file reproduction processing unit (0202), the reproduction information file processing unit (0203), and the effect processing unit (0204). When the moving image file is reproduced by the moving image file reproduction processing unit (0202), the effect processing unit (0204) performs effect processing based on the reproduction information file analyzed by the reproduction information file processing unit (0203). The operation management unit (0205) controls these processes centrally.

  Specifically, first, the reproduction information file name is acquired by the GUI according to the operation of the user, and this is notified to the reproduction information file processing unit. Further, after being analyzed by the reproduction information file processing unit, the reproduction information file is notified to the moving image file reproduction processing unit via the operation management unit. In addition, an effect instruction is sent to the effect processing unit to trigger the effect processing start. In addition, a breaking news or the like sent in a broadcast wave may be used as a trigger for starting the effect processing.

  <Embodiment 1: Process Flow> FIG. 4 shows an example of the flow of effect processing in the first embodiment. First, reading / writing and analysis of a reproduction information file describing control information related to reproduction processing including the reproduction position of the moving image file are performed (reproduction information file processing step S0401). Next, the moving image file is reproduced (moving image file reproduction processing step S0402). Next, the effect start time is compared with the time when the playback of the moving image file has progressed (referred to here as elapsed playback time) (effect start time comparison step S0403). If the elapsed playback time has not reached the effect start time, the process returns to the moving image file playback processing step (S0402). On the other hand, when the playback elapsed time reaches the effect start time, data for one frame of the moving image file and image frame data for one frame of the next moving image file are generated, stored in the work memory, and reproduced information Based on the file, effect processing is performed using a plurality of image frame data in the work memory (effect processing step S0404). By repeating this effect processing step (S0404) for an effect period, it is possible to perform effect processing over a plurality of frames.

  The above processing can be executed by a program for causing a computer to execute, and the program can be recorded on a recording medium readable by the computer. (The same applies throughout the specification.)

  <Embodiment 1: Effect> This embodiment is a continuous reproduction system that performs effect processing using image frame data for an arbitrary plurality of frames so that two files are switched naturally. By using the effect effect when switching the reproduction of two moving image files, it is possible to provide the user with a rich image display without human intervention. In addition, since the effect of the effect based on the playback information file can be used to alleviate rapid image switching, an effect of promoting the playback and viewing of a large number of moving image files to the user can be expected. Furthermore, since information related to playback control can be described in the playback information file, it is possible to arbitrarily set the effect type between videos, the timing for effecting, the display period, etc. Is expensive.

  << Embodiment 2 >>

  <Embodiment 2: Overview> Embodiment 2 will be described. The present embodiment is a continuous reproduction system characterized in that the storage unit is located in at least one of a terminal on which a continuous reproduction system is mounted, a peripheral device outside the terminal, or an external network.

  <Embodiment 2: Configuration> FIG. 5 shows an example of functional blocks in the present embodiment. The “continuous playback system” (0500) of this embodiment shown in FIG. 5 includes a “storage unit” (0501) and a “terminal device” (0510). The terminal device is a “video file playback processing unit” ( 0511), “reproduction information file processing unit” (0512), “effect processing unit” (0513), and “operation management unit” (0514).

  The “storage unit” (0501) is in at least one of the inside of the terminal on which the continuous reproduction system is mounted, a peripheral device outside the terminal, or an external network. 2 shows a diagram in which the storage unit is inside the terminal equipped with the continuous playback system. FIG. 5 schematically shows a state in which the storage unit is on a peripheral device outside the terminal and on an external network. did. The storage part inside the terminal and the storage part on the external network are normally used by determining the path name when specifying the file name. Specifically, in the case of a storage unit inside the terminal, a combination consisting of a reproduction information file name after the drive name is used. In a case of a storage unit on an external network, a combination consisting of a reproduction information file name after the URL is used. Applicable. The processing of each other part is the same as in the first embodiment.

  <Embodiment 2: Process Flow> FIG. 6 shows an example of the process flow in the second embodiment. First, playback that describes control information related to playback processing, including the playback position of a video file, from a storage unit inside a terminal equipped with a continuous playback system, a peripheral device outside the terminal, or a storage unit on the external network The information file is read and analyzed (reproduction information file processing step S0601). Next, the moving image file is read out from the storage unit and the moving image file is reproduced (moving image file reproduction processing step S0602). Next, the effect start time is compared with the time when reproduction of the moving image file has progressed (referred to here as elapsed playback time) (effect start time comparison step S0603). If the elapsed playback time has not reached the effect start time, the process returns to the moving image file playback processing step (S0602). On the other hand, when the playback elapsed time reaches the effect start time, data for one frame of the moving image file and image frame data for one frame of the next moving image file are generated, stored in the work memory, and reproduced information Based on the file, effect processing is performed using a plurality of image frame data in the work memory (effect processing step S0604). The effect processing step (S0604) is repeated for the effect period.

  <Embodiment 2: Effect> In this embodiment, continuous playback is characterized in that the storage unit is in at least one of the inside of the terminal equipped with the continuous playback system, the peripheral device outside the terminal, or the external network. System. When the storage unit is inside a terminal equipped with a continuous reproduction system, it is advantageous that a moving image file and a reproduction information file can be accessed immediately. On the other hand, when the storage unit is on a peripheral device outside the terminal or on an external network, it is advantageous that a large file can be stored. In particular, since a moving image file has a large file size, it is preferable to have a storage unit outside the terminal. Further, since a third party other than the user such as an administrator can manage and maintain the storage unit, it is highly convenient.

  << Embodiment 3 >>

  <Embodiment 3: Overview> Embodiment 3 will be described. In this embodiment, the management of the timing for creating image frame data for an arbitrary number of frames, and the operation management of the image frame data generated by performing processing for reproducing different types of data included in the moving image file for each type. The continuous reproduction system is characterized in that it is stored in a memory managed by the unit.

  <Embodiment 3: Configuration> FIG. 7 shows an example of functional blocks in the present embodiment. The “continuous playback system” (0700) of this embodiment shown in FIG. 7 includes a “storage unit” (0701), a “movie file playback processing unit” (0702), and a “playback information file processing unit” (0703). , “Effect processing unit” (0704) and “Operation management unit” (0705). Furthermore, the moving image file reproduction processing unit (0702) includes a “data processing unit” (0706) and an “image frame data generation unit” (0707).

  The “data processing means” (0706) performs processing for reproducing different types of data included in the moving image file for each type. The moving image file is composed of one or a combination of two or more different types of data such as image data, audio data, and telop data. Reproduction is performed according to these types. In order to reduce the file capacity, image data and audio data are often encoded and stored in a compressed state. In this case, it is necessary to perform a decoding process to reproduce the data. is there.

  As encoding methods, there are a method of generating and encoding one basic frame data and its difference frame data, and a method of generating and encoding data completed in each frame. The former is a known method as an image encoding method and decoding method using inter-frame prediction. For images, MPEG4, H.264. There is a system such as H.263, and the AMR system is famous for voice. On the other hand, the latter is a method called motion JPG, in which each frame is coded continuously using a coding method called JPG. Since the difference information between the preceding and succeeding frames is not used, the compression efficiency at the same bit rate is lower than that of the former method, but any part can be easily edited. Here, image data and audio data included in a moving image file are encoded using inter-frame prediction, and different types of data such as image data, audio data, and text data (telop) are multiplexed. A description will be made assuming that the file format is used. However, other forms are not excluded.

  As shown in FIG. 8, the moving image file is roughly divided into a header portion (0800) and a data portion (0810). The header portion includes playback time information (0801) of the moving image file, image encoding format information (0802) included in the file, encoding format type information (0803) such as an audio encoding format, and minimum management in the data portion. Address information (0804) indicating the position of each management unit of image data, audio data, and telop data stored separately in units is included. The data portion stores a plurality of minimum management units of image data, audio data, and telop data (0811 to 0816). Here, the minimum management unit of data is an image, audio stream data, and a series of character strings. For example, in an image, one frame is composed of one minimum management unit V1, V2,. In a voice, an arbitrary plurality of frames are composed of one minimum management unit A1, A2,..., And in a telop, an arbitrary plurality of characters having the same telop attribute are defined as one minimum management unit T1, T2,.

  First, prior to data processing, the address of the minimum management unit included in the header of the moving image file is searched, the data of the minimum management unit is extracted for each image, audio, and telop, and a series of image and audio stream data and telop are extracted. Performs processing to reconstruct all characters on the work memory. Next, in order to perform processing for reproducing different types of data included in the video file for each type, data corresponding to each block (image processing block, audio processing block, telop processing block) is transferred to the video file. Is decrypted.

  Here, the contents of the stream data of the image will be described. The stream data is a series of data in which data in units of frames are continuous, and is composed of basic frame data, that is, I frames, and difference frame data, that is, P frames. The I frame is a frame including all data of information necessary for decoding one frame, and the P frame is a frame having only difference data from the immediately preceding frame. That is, for example, when decoding image data, first, decoding processing for one frame is performed using an I frame, and then based on decoding-completed data for one frame and a P frame with only a difference. Then, the decoding process for the next one frame is performed. Effect processing may also be performed for audio and telop. At that time, each of the image, the sound, and the telop may perform the effect processing synchronously or may perform the effect processing asynchronously.

  “Image frame data generation means” (0707) manages the timing for creating image frame data for an arbitrary number of frames, generates image frame data from the moving image file processed by the data processing means (0706), The data is stored in a memory managed by the operation management unit (0705). Specifically, the timing for creating the image frame data is managed by comparing the effect start time with the time at which the reproduction of the moving image file has progressed (referred to here as the elapsed playback time) in the data processing means (0706). . The video file playback process is continued until the playback elapsed time reaches the effect start time. On the other hand, when the playback elapsed time reaches the effect start time, data of one frame of the latest moving image file among the decoded frame data is stored in the memory managed by the operation management unit (0705). Next, the subsequent moving image file is read, image frame data for one frame is generated, and stored in a memory managed by the operation management unit. The effect processing unit (0704) generates one piece of image data to which a special effect is applied using two pieces of image frame data in the memory. By continuously displaying the image data generated by the effect processing on the screen, various screen switching effects can be obtained.

  The processing of each other part is the same as in the first embodiment. Further, as in the second embodiment, the storage unit of the present embodiment may be provided in at least one of the inside of the terminal on which the continuous reproduction system is mounted, the peripheral device outside the terminal, or the external network.

  <Third Embodiment: Flow of Processing> FIG. 9 shows an example of the flow of effect processing in the third embodiment. First, read / write and analysis of a reproduction information file describing control information related to reproduction processing including the reproduction position of a moving image file is performed (reproduction information file processing step S0901). Next, a process of reproducing different types of data included in the moving image file for each type is performed (data processing step S0902). Next, the effect start time is compared with the time when the playback of the moving image file has progressed (referred to here as elapsed playback time) (effect start time comparison step S0903). If the elapsed playback time has not reached the effect start time, the process returns to the data processing step (S0902). On the other hand, when the playback elapsed time reaches the effect start time, the latest one frame data of the decoded video file and the image frame data of one frame of the next video file are generated and stored in the memory. (Image frame data generation step S0904). Finally, effect processing is performed using the image frame data in the memory (effect processing step S0905). These image frame data generation step (S0904) and effect processing step (S0905) are repeated for the effect period.

  <Embodiment 3: Effect> This embodiment is generated by managing the timing of creating image frame data for an arbitrary number of frames and processing for reproducing different types of data included in a video file for each type A continuous reproduction system characterized in that image frame data is stored in a memory managed by an operation management unit. By managing the timing of creating the image frame data, it is possible to display the effect-processed image while decoding the two moving images, and various image switching effects can be obtained.

  << Embodiment 4 >>

  <Embodiment 4: Overview> Embodiment 4 will be described. The present embodiment is a continuous playback system that notifies the operation management unit of an elapsed playback time during playback processing of a moving image file.

  <Embodiment 4: Configuration> FIG. 10 shows an example of functional blocks in the present embodiment. The “continuous playback system” (1000) of this embodiment shown in FIG. 10 includes a “storage unit” (1001), a “moving image file playback processing unit” (1002), and a “playback information file processing unit” (1003). , “Effect processing section” (1004) and “Operation management section” (1005). Furthermore, the moving image file reproduction processing unit (1002) has “reproduction elapsed time notification means” (1006).

  The “reproduction elapsed time notification means” (1006) notifies the operation management unit (1005) of the elapsed reproduction time during the reproduction process of the moving image file. If the elapsed playback time is notified to the operation management unit along with the playback processing of the moving image file, it can be compared with the effect start time information in the playback information file analyzed by the playback information file processing unit (1003). If the elapsed playback time has not reached the effect start time, normal playback processing may be continued. On the other hand, when the elapsed playback time reaches the effect start time, it is necessary to start effect processing in the effect processing unit (1004).

  The processing of each other part is the same as in the first embodiment. Further, as in the second embodiment, the storage unit of the present embodiment may be provided in at least one of the inside of the terminal on which the continuous reproduction system is mounted, the peripheral device outside the terminal, or the external network. Further, as in the third embodiment, the moving image file reproduction processing unit of the present embodiment manages the timing for creating image frame data for an arbitrary number of frames, and sets different types of data included in the moving image file for each type. In some cases, the image frame data generated by performing the reproduction process is stored in a memory managed by the operation management unit.

  <Fourth Embodiment: Processing Flow> FIG. 11 shows an example of the flow of effect processing in the fourth embodiment. First, reading / writing and analysis of a reproduction information file describing control information related to reproduction processing including the reproduction position of a moving image file are performed (reproduction information file processing step S1101). Next, reproduction processing of the moving image file is performed (moving image file reproduction processing step S1102). Then, the elapsed playback time during the playback process of the moving image file is notified (reproduction elapsed time notification means step S1103). Further, the reproduction elapsed time notified in the reproduction elapsed time notification step (S1103) is compared with the effect start time (effect start time comparison step S1104).
