  However, in the conventional video / audio editing apparatus, the user needs to assign audio material to an arbitrary audio channel. At this time, if different audio materials are assigned to the same channel in the previous and subsequent configurations, there are many cases where the audio effect expected by the user cannot be realized. On the other hand, in order to avoid the above-mentioned case, there is no method other than assigning audio material while the user is aware of the assigned channel, and the production of the cue sheet becomes very complicated.

  In addition, audio effects such as fade-in and fade-out associated with the video effect are additional information of the video effect and are not displayed on the screen. On the other hand, in order to realize the above audio effect, the user must always be aware of the video effect at the time of registering the audio material, and must create cue sheets so that the audio channels do not overlap, and is forced to perform complicated operations. .

  In particular, since the news support system is mainly used for news programs, it is necessary to cope with urgent editing such as change, insertion and deletion of materials because of the peculiarity that editing of a cue sheet immediately before broadcasting is indispensable.

  The news report support system 1 is linked with an external branch office or branch office and can share various data. It is also possible to receive data from an interviewee via an external network. The news report support system 1 is connected to the AV server system 2 via a gateway server.

  The AV server system 2 is provided with a material server 201 for storing various video materials and audio materials, and provides necessary video materials and audio materials according to the contents of the cue sheet created by the news report support system 1. It can be done. The AV server system 2 is also configured to connect various computers and servers to an internal network. For example, a nonlinear editing computer, a filing computer, a playout computer, and a material computer are network-connected. Such an AV server system 2 reads various video materials and audio materials from the material server 201 in accordance with the contents of the cue sheet created by the news report support system 1, and sends the transmission support system 3 via the playout server. Sent out.

  The transmission support system 3 is provided with switchers / mixers 301 and 302 for receiving various video materials and audio materials sent from the AV server system 2 in time series according to the contents of the cue sheet created by the news report support system 1. It is the part that controls the progression of the program by switching and synthesizing with other video, audio and graphic data.

  A program creation computer 101 (or composition input computer 102) of a news report support system to which the present embodiment is applied in such a broadcasting system has a configuration as shown in FIG. That is, the program creation computer includes a CPU 112 that executes various controls and a video / audio editing program according to the present embodiment, a main storage device 113 that temporarily stores programs and data, and a nonvolatile large-capacity storage that includes a hard disk drive.

The functions of this embodiment are realized by being executed by the CPU 112 in any case.

  FIG. 3 is a block diagram showing an example of the software configuration of the broadcast system shown in FIG. In the news report support system 1, a program table ST02 is created using a composition table ST01 that is a cue sheet template created by the composition input computer 102 (see FIG. 1). The user adds, corrects, deletes, etc. to the configuration of the cue sheet by the program operation by the program creation computer 101 (see FIG. 1) using the program table ST01 as a basic type, and then configures the program configuration table ST12 (cue sheet used as a program). STQ) is created. When the composition composition table ST11 (model of the program composition table) created in advance by the composition input computer 102 is used, the program composition table ST12 is created by copying it to the program composition computer 101. Also good.

  The transmission support system 3 uses the program configuration table ST12 created by the news report support system 1 as a cue sheet STQ, and various videos from the external AV server system 2 (see FIG. 1) in time series according to the contents of the cue sheet STQ. In response to the material and the sound material, the data is sequentially transmitted to the broadcasting device M.

  With respect to software executed in various systems, common setting / common function unit 10 performs system setting, user setting, and advance setting. These settings can be made by the user by the computer of each system. Settings for the entire system are made by an administrator as a user, and each user can make user interface and tool settings for each user.

  In the video / audio editing program according to the present embodiment, when creating cue sheets such as the program organization table ST12 and the organization structure table ST11, consideration is given so that the cue sheet can be created quickly and accurately.

  Next, the video / audio editing program according to the present embodiment will be described. In the present embodiment, a video / audio editing program that mainly performs two optimization processes is mainly used. One is realized by the user interface shown in FIG. 5 (first embodiment described later), and the other is realized by the user interface shown in FIG. 6 (second embodiment described later). In any case, a user interface called a pallet shown in FIG. 4 selects a configuration in the cue sheet, assigns video materials and audio materials to the configuration, and designates various video effects and audio effects.

  As shown in FIGS. 5 and 6, the palette is displayed beside the screen showing the contents of the cue sheet. When a desired configuration is selected from the screen display of the cue sheet, the palette is assigned in accordance with the configuration. Displayed video and audio materials. Here, the cue sheet displays a large item and a small item belonging to the large item. For example, when the user designates a large item with a mouse or the like, the user can refer to the display of the small items belonging to the large item. This small item corresponds to the configuration of the present embodiment, and each configuration (small item) is arranged in time series with the configuration time.

  In addition, the video material and audio material assigned in the cue sheet screen display and palette screen display are displayed in the index display (reduced display of the typical screen) and the display by file name. It is easy for the user to grasp whether or not.

  The basic operation when creating a cue sheet is to first select a configuration for assigning video material and audio material from the cue sheet displayed on the screen by a user operation with a mouse or the like, or create a new configuration. Start with the add operation.

  When the user selects or adds a desired configuration, the portion of the configuration to be edited is displayed separately from other configurations, and it can be understood that a specific configuration has been selected. Along with this selection, the video material and audio material currently assigned to the configuration are displayed on the palette. When a new configuration is added or nothing is assigned, nothing is displayed in the video material or audio material input fields.

  When assigning video material corresponding to the selected configuration, first, the “video” tab portion of the palette is selected with a mouse or the like, and the video material setting column 401 is designated with the mouse or the like. As a result, the assignable video material is displayed in the lower reference column 402 in the palette, and when the desired video material is designated with the mouse or the like, the designated video material is input to the setting column 401. In this video allocation, the main video material, video material to be synthesized, video effects, and other video material to be superimposed on the main video can be designated.

  In order to assign audio material, the “audio” tab portion of the palette is selected with a mouse or the like, and the audio material setting field 401 is designated with the mouse or the like. In this embodiment, the audio material is assigned to each of the two channels, but may be assigned to more channels because of the relationship with the hardware. Also, BGM (Back Ground Music) is secured as a separate channel.

  In the assignment of audio material, as in the case of video material, when a channel setting column 401 to be assigned is designated with a mouse or the like, the assignable audio material is displayed in the reference column 402 on the lower side of the palette, and desired audio is selected from that. When a material is designated with a mouse or the like, the designated audio material is input to the setting field 401. In the specification of the sound material, sound effects such as fade-in and fade-out, and sound effect parameters can be set.

  In the display example of the pallet shown in FIG. 4, the state of the audio material among the materials assigned to the predetermined configuration is shown. The predetermined audio material is assigned to the audio 1 and BGM setting fields 401, and the audio 2 In the setting column 401, nothing is assigned.

  The user repeats specification of the cue sheet display configuration, specification of various materials using the palette, and specification of the effect using an input unit such as a mouse or a keyboard to create the entire cue sheet.

(First embodiment)
FIG. 5 is a diagram illustrating an example of a screen of a program configuration table and an organization configuration table. In the upper diagram of FIG. 5, reference numeral 501 denotes a screen displaying a list of video materials and audio materials set manually in the palette shown in FIG. Indicates. In the lower part of FIG. 5, reference numeral 502 indicates a state after the optimization of the channel assignment of the audio material.

  In the optimization processing according to the first embodiment, the video material allocated to one configuration (for example, configuration 3-3 in FIG. 5) is allocated to the immediately previous configuration (for example, configuration 3-2 in FIG. 5). If the video material is not the same, a process of assigning the audio material selected corresponding to one configuration to a channel different from the channel of the audio material assigned to the immediately previous configuration is performed. That is, when different audio materials are assigned to the same audio channel in the front and rear configurations, the audio materials are optimized so as not to be assigned to the same audio channel.

(flowchart)
FIG. 7 is a flowchart showing the processing contents to be optimized so that the audio channels do not overlap when different audio materials are assigned to the same audio channel in the front and rear configurations. In the present embodiment, when the audio material is manually set on the pallet shown in FIG. 4, the channel of the audio material of the front and rear configuration is confirmed, and the audio channel is automatically optimized and changed.

  First, the composition information (video material / audio material / video effect) in the program is confirmed from the top of the created cue sheet (here, the cue sheet is called a program) (step S101). Next, it is detected whether a video effect is registered in the confirmed configuration (step S102).

  Here, when the video effect is registered, it is confirmed whether or not the audio material is registered in the configuration (own configuration) (step S103). If the audio material has been registered, it is confirmed whether or not there is a free space in the self-configured audio channel (step S104).

  If there is a vacancy, it is confirmed whether there is a vacancy in the voice channel of the previous configuration (configuration immediately before the own configuration) (step S105). If there is a vacancy in the audio channel of the previous configuration, the audio material assignment is changed (optimized) to the empty channel of the own configuration so that the audio channel of the audio material of the own configuration does not overlap with the audio channel of the previous configuration (step S106). ).

  On the other hand, if the optimization is impossible in Steps S103 and S104, the fact that the channel assignment optimization could not be executed is indicated to the user as an alarm target, and the user is prompted to perform manual setting (Step S110).

  Further, when changing (optimizing) the channel of the audio material of the own configuration in step S106, it is confirmed whether the same audio material as that of the own configuration is continuously used in the configuration subsequent to the own configuration (step S107). When the same audio material is continuous in the own configuration and the subsequent configuration, the allocation is performed so that the audio material becomes the same audio channel for all the configurations using the continuous audio material (step S108). ).

  Thereafter, it is confirmed whether or not there is the next structure in the program (step S109), and if it exists, the process returns to step S102, and the subsequent processes are repeated.

  With the above processing flow, since the audio material is automatically assigned to the optimum audio channel according to the situation of the front and rear configuration, manual setting by the program producer (user) is reduced, and work efficiency can be improved. .

(Second Embodiment)
FIG. 6 is a diagram showing an example of the screen of the program composition table and the organization composition table similar to FIG. This is an example of optimization. In the upper diagram of FIG. 6, reference numeral 601 denotes a screen displaying a list of video materials and audio materials manually set in the palette shown in FIG. Indicates. In the lower diagram of FIG. 6, reference numeral 602 indicates a state after optimization of channel assignment of audio material.

  In the optimization processing according to the second embodiment, the video material allocated to one configuration (for example, configuration 3-3 in FIG. 6) is allocated to the immediately preceding configuration (for example, configuration 3-2 in FIG. 6). When the video materials are the same, a process of assigning the audio material selected corresponding to one configuration to the same channel as the channel of the audio material assigned to the immediately previous configuration is performed. That is, if the audio material used in the front and rear configurations is the same, it means that the audio material is used continuously. At this time, if the audio material is continuously used in the same channel, the audio channel is effectively used and the time for performing standby processing of the audio device can be shortened, so that smooth broadcasting is possible.

(flowchart)
FIG. 8 is a flowchart showing the contents of processing for optimizing the same audio channel when the same audio material is assigned to different audio channels in the front and rear configurations. In this embodiment, when audio material is set manually using the palette shown in FIG. 4, the channels of the audio material of the front and rear configurations are confirmed, and the audio channel is automatically optimized and changed if possible according to the conditions. .

  The difference from the processing shown in FIG. 7 is that when the same audio material is registered in audio channels with different front and rear configurations, the same audio channel is assigned. As a result, the complexity of control for standby the same audio material on different audio channels when on-air, and the operability of audio effects such as manual faders are improved. Here, the fader is a part of the audio mixer, and is a part that is operated to determine the sound volume.

  First, the configuration information in the program is confirmed from the top of the created cue sheet (here, the cue sheet is referred to as a program) (step S201). Next, it is confirmed whether or not audio material is registered in its own configuration (step S202). When the audio material is registered in the own configuration, it is confirmed whether the same audio material is registered in the previous configuration (the configuration immediately before the own configuration) (step S203).

  If the same audio material is registered, the own audio channel is changed (optimized) so that the audio channel of the own audio material is the same as that of the previous audio channel (step S204). At this time, if there is no vacancy in the audio channel of its own configuration, the other audio material and the audio channel are switched.

  When changing (optimizing) the audio channel of the audio material of its own configuration, it is confirmed whether the same audio material as that of its own configuration is continuously used in the following and subsequent configurations of the own configuration (step S205). When the same audio material is continuous in the own configuration and the subsequent configuration, the allocation is performed so that the audio material becomes the same audio channel for all the configurations using the continuous audio material (step S206). ).

  Thereafter, it is confirmed whether or not there is the next structure in the program (step S207), and if it exists, the process returns to step S202, and the subsequent processes are repeated.

  With the above processing flow, since the audio material is automatically assigned to the optimum audio channel according to the situation of the front and rear configuration, manual setting by the program producer (user) is reduced, and work efficiency can be improved. .

  FIG. 9 is a diagram illustrating an example of an audio crossfade as an example of the audio effect that can be realized by the present embodiment. Here, cross fading means that by assigning different audio materials to different audio channels, the audio 1 fades out and the audio 2 fades in (audio cross fade) to produce an attractive broadcast. .

  Here, the execution timing of the process shown in FIG. 7 (the process of the first embodiment) and the process shown in FIG. 8 (the process of the second embodiment) will be described. The process of the first embodiment and the process of the second embodiment are the program creation used when the user creates a cue sheet by the program creation computer 101 (see FIG. 1) or the composition input computer 102 (see FIG. 1). It is implemented as a function of the application software for the user, and it is possible to select whether or not to execute the process of the first embodiment and the process of the second embodiment with an arbitrary setting by the user. This setting is stored in the user setting of the common setting / common function unit 10 shown in FIG.

  In user settings, (1) execute only the process of the first embodiment, (2) execute only the process of the second embodiment, (3) execute both the process of the first embodiment and the process of the second embodiment. Either (4) Do not execute any process can be set according to the preference of each user.

  In addition, as the execution timing of the set processing, the above processing is automatically executed when a desired audio material is selected in order to allocate video material to one configuration and then allocate audio material to the same configuration. In addition, after the video material and the audio material are assigned to a desired configuration, the above-described processing may be executed at the stage when the user gives a start instruction.

  In the former case, even if there is an urgent configuration change, it is possible to respond quickly without making the user aware of the assignment channel, and in the latter case, a manually created cue sheet or stored once It is possible to use such as calling a certain cue sheet and correcting the allocated channel in a batch as needed. In addition, it is possible to determine at which timing automatic assignment is executed by user settings.

  Thus, by using this embodiment, the user can prepare the necessary audio material without being aware of the audio channel at the stage of creating the cue sheet. This is especially important in news production sites where preparations are made in a short time. In addition, in the present situation where one broadcast program is made up by a large number of persons in charge, news items before and after are often replaced. By using this embodiment, since the voice channel straddling the news item is also targeted, the effect of convenience is great.

  In addition, since the prepared audio material is immediately assigned to the optimum audio channel, it is possible to cope with a configuration change in a short time even when a sudden change in broadcast content occurs during on-air. Furthermore, by optimizing the allocation of audio channels, audio material is also effectively transmitted in accordance with the video effect desired by the user in actual on-air, so it is possible to produce a more attractive broadcast (for example, Voice cross fade: see FIG. 9).

  Further, by assigning the same audio material before and after to the same audio channel, the operability of the manual fader during on-air is improved, and the audio level can be effectively switched during on-air.

  Furthermore, in this embodiment, an optimization method can be set in accordance with the user needs of video and audio, and whether or not to use the processing contents of this embodiment can be switched. It can be realized over
