[Embodiment 1]
FIG. 1 is a block diagram illustrating a broadcast content providing system 1000 according to the first embodiment. In FIG. 1, each block represents a functional unit configuration, not a hardware unit configuration.
  The broadcast content providing system 1000 includes a broadcast content providing apparatus 200 and a playback apparatus 300. The broadcast content providing apparatus 200 generates video data for television broadcasting (hereinafter referred to as video data for television broadcasting) and video data for network distribution (hereinafter referred to as network distribution video data). Television broadcast video data is video data that is broadcast on television, and is broadcast, for example, to the television of each home via terrestrial waves. On the other hand, the network distribution video data is video data distributed to the playback device 300 via the network. The playback apparatus 300 is various computers such as a mobile terminal such as a smartphone and a PC (Personal Computer). Further, the playback device 300 may be a television connected to a network. Hereinafter, distributing data via a network is also referred to as “distributing network”.
  Both the TV broadcast video data and the network distribution video data are generated based on the video data of broadcast content (hereinafter referred to as source video data). Broadcast content is content other than CM. FIG. 2 is a diagram illustrating the structures of source video data, television broadcast video data, and network distribution video data, respectively. FIG. 2A shows source video data. The source video data shown in FIG. 2 (a) is composed of three video data (source 1 to source 3) at the position where the CM enters.
  FIG. 2B shows TV broadcast video data. The TV broadcast video data is composed of source video data and video data of TV broadcast CM content (hereinafter, TV broadcast CM video data). Hereinafter, the period occupied by CM in TV broadcast video data and network distribution video data is called CM period. The CM period can be rephrased as a period between the time when the frame of the source video data just before the start of the CM is played back and the time when the frame of the source video data just after the end of the CM is played back. In FIG. 2 (b), CM video data 1 (TVCM1) for television broadcasting is inserted in the CM period 1 between the source 1 and the source 2, and the CM period between the source 2 and the source 3 is inserted. 2 is inserted into CM video data 2 (TVCM2) for television broadcasting.
  FIG. 2C shows network distribution video data. The network distribution video data includes the source video data as well as the television broadcast video data. The source video data included in the network distribution video data has the same content as the source video data included in the television broadcast video data. On the other hand, network distribution video data includes video data other than TV video CM video data in each CM period. In other words, the network distribution video data can be expressed as television broadcast video data in which a television broadcast CM is replaced with another video. Hereinafter, video data other than the TV video CM video data inserted in the CM period of the network distribution video data is referred to as default CM video data. The contents of default CM video data will be described later. Note that the various video data handled by the broadcast content providing system 1000 may be analog data or digital data.
  FIG. 3 is a diagram conceptually illustrating the operation of the broadcast content providing apparatus 200 according to the first embodiment. In FIG. 3, a broadcast content providing apparatus 200 generates television broadcast video data and network distribution video data from source video data. The broadcast content providing apparatus 200 broadcasts television broadcast video data and distributes network distribution video data over the network.
  FIG. 4 is a diagram illustrating a broadcast content providing apparatus 200 according to the first embodiment. In FIG. 4, each block represents a functional unit configuration, not a hardware unit configuration.
  In order to handle television broadcast video data, the broadcast content providing apparatus 200 includes a broadcast video data generation unit 202 and a broadcast unit 204. The broadcast video data generation unit 202 inserts CM video data for TV broadcast during the CM period in the source video data, and generates TV broadcast video data. The broadcast unit 204 broadcasts the generated television broadcast video data.
  In order to handle network distribution video data, the broadcast content providing apparatus 200 includes a distribution video data generation unit 206 and a distribution unit 208. The distribution video data generation unit 206 generates network distribution video data by inserting default CM video data into the CM period of the source video data. The distribution unit 208 distributes network distribution video data to the playback device 300 over the network.
<Action and effect>
According to the broadcast content providing system 1000, the video of the broadcast content portion can be made common between the video broadcast on the television and the video distributed over the network, and the video of the CM portion can be made different. Therefore, even if the TV broadcast CM cannot be distributed via the network due to the contract, the broadcast content broadcast on the TV can be distributed simultaneously on the network.
  Hereinafter, the present embodiment will be described in further detail.
<Example of Hardware for Realizing Broadcast Content Providing Apparatus 200>
Each functional component of the broadcast content providing apparatus 200 may be realized by hardware (for example, a hard-wired electronic circuit) that realizes each functional component, or a combination of hardware and software (for example, : A combination of an electronic circuit and a program for controlling the electronic circuit).
  FIG. 5 is a diagram illustrating a hardware configuration of the computer 100 that implements the broadcast content providing apparatus 200 according to the first embodiment. The computer 100 may be a dedicated computer designed for generating video data such as a television program, or may be a general-purpose computer such as a PC (Personal Computer) or a server.
  The computer 100 includes a bus 102, a processor 104, a memory 106, a storage 108, an input / output interface 110, and a network interface 112. The bus 102 is a data transmission path through which the processor 104, the memory 106, the storage 108, the input / output interface 110, and the network interface 112 transmit / receive data to / from each other. However, the method of connecting the processors 104 and the like is not limited to bus connection. The processor 104 is an arithmetic processing device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The memory 106 is a memory such as a random access memory (RAM) or a read only memory (ROM). The storage 108 is a storage device such as a hard disk, an SSD (Solid State Drive), or a memory card. The storage 108 may be a memory such as a RAM or a ROM.
  The input / output interface 110 is an interface for connecting the computer 100 and an input / output device. For example, a keyboard and a mouse are connected to 110.
  The network interface 112 is an interface for connecting the computer 100 to an external device so as to be communicable. The network interface 112 may be a network interface for connecting to a wired line or a network interface for connecting to a wireless line.
  The computer 100 is connected to the playback device 300 via the network interface 112. The network between the computer 100 and the playback device 300 is, for example, the Internet. By distributing the network distribution video data output from the computer 100 to the playback device 300 via the network, the function of the distribution unit 208 is realized.
  The computer 100 is connected to the television transmitter 10 via the network interface 112. The television transmitter 10 is hardware for broadcasting a video image via terrestrial waves or the like. The network between the computer 100 and the television transmitter 10 is an in-house network such as a television station. By broadcasting the television broadcast video data output from the computer 100 from the television transmitter 10, the function of the broadcast unit 204 is realized.
  The storage 108 stores program modules that realize each function of the broadcast content providing apparatus 200. The processor 104 implements each function corresponding to the program module by executing each program module. Here, when executing the above-described modules, the processor 104 may execute these modules after reading them onto the memory 106, or may execute them without reading them onto the memory 106.
  The hardware configuration of the computer 100 is not limited to the configuration shown in FIG. For example, each program module may be stored in the memory 106. In this case, the computer 100 may not include the storage 108.
<Process flow>
FIG. 6 is a flowchart illustrating the flow of processing executed by the broadcast content providing apparatus 200 according to the first embodiment. The broadcast content providing apparatus 200 acquires source video data (S102). The broadcast video data generation unit 202 generates television broadcast video data (S104). The distribution video data generation unit 206 generates network distribution video data (S106). The broadcast unit 204 broadcasts television broadcast video data (S108). The distribution unit 208 distributes network distribution video data over the network (S110).
<About acquisition of source video data>
The broadcast content providing apparatus 200 acquires source video data (S102). The method by which the broadcast content providing apparatus 200 acquires the source video data is arbitrary. For example, the broadcast video data generation unit 202 acquires the source video data from a storage device or server that stores the source video data.
  Note that there are various units of source video data acquired by the broadcast content providing apparatus 200. For example, the broadcast video data generation unit 202 may acquire source video data for one entire program at a time. Such acquisition is performed, for example, in the case of a program in which broadcast content to be handled is recorded. Further, for example, the broadcast video data generation unit 202 may acquire the source video data generated sequentially for each part of the program (for example, in units of frames). Such acquisition is performed, for example, when the broadcast content to be handled is a live broadcast program.
  Here, the source video data representing one recorded program may be composed of a plurality of video data divided before and after the CM, or may be composed of a single piece of video data. However, in the latter case, the broadcast video data generation unit 202 and the distribution video data generation unit 206 need to be able to grasp the position of the CM period. For example, the broadcast content providing apparatus 200 acquires the source video data together with information indicating the position of each CM period in the source video data. In addition, for example, the start position of the CM period and the metadata of the frame immediately before that indicate information indicating the start position of the CM period and the frame immediately before it.
<About Broadcast Video Data Generation Unit 202 and Broadcast Unit 204>
Since a technique for generating TV broadcast video data by inserting CM video data for TV broadcast into source video data is a known technique, detailed description of the technique is omitted. Further, since the technology for broadcasting on television broadcast video data and terrestrial waves is a known technology, detailed description of the technology is omitted.
<About Distribution Video Data Generation Unit 206>
The distribution video data generation unit 206 inserts default CM video data into the source video data to generate network distribution video data (S106). Here, the distribution video data generation unit 206 may 1) generate the entire network distribution video data in advance, or 2) generate the network distribution video data at a timing when the distribution unit 208 distributes the network distribution video data. May be.
  FIG. 7 is a diagram showing the difference between 1) and 2). In FIG. 7, S1 to S4 are frames constituting source video data, and C1 and C2 are frames constituting default CM video data. The CM period is between S2 and S3.
  In FIG. 7A, the broadcast content providing apparatus 200 acquires a video file representing the entire source video data of one program. This program is a recorded broadcast program. Distribution video data generation unit 206 inserts default CM video data in each CM period of source video data prior to distribution of network distribution video data to generate the entire network distribution video data. Thereafter, the distribution unit 208 distributes each frame of the network distribution video data.
  On the other hand, in FIG. 7B, the broadcast content providing apparatus 200 acquires the source video data constituting the live broadcast program frame by frame. The distribution unit 208 distributes each acquired frame until the commercial period starts. In the CM period, the distribution video data generation unit 206 distributes each frame of the default CM video data after the frame (S2) immediately before the CM period of the source video data. When the CM period ends, the distribution unit 208 distributes the continuation of the source video data (S3 transition).
<< About default CM video data >>
Arbitrary video data can be used as default CM video data. For example, default CM video data is video data in which a predetermined still image is repeated. The predetermined still image may be an arbitrary image, for example, a white or black image. The predetermined still image may be a plurality of still images. In this case, the default CM video data is an animation composed of a plurality of frames. For example, the predetermined image is assumed to be seven images each displaying the seven characters constituting the word “LOADING”. By doing this, the default CM video data becomes a video representing the word “LOADING” in animation.
  The default CM video data may be CM video data other than CM video data for television broadcasting. For example, the CM video data is a CM (for example, a CM of the TV station itself or a CM of a special program scheduled to be broadcast in the future) created by a TV station that broadcasts the source video data.
  The default CM video data may be stored in advance in a storage device accessible from the broadcast content providing apparatus 200, or may be dynamically generated by the broadcast content providing apparatus 200. When the default CM video data is dynamically generated by the broadcast content providing apparatus 200, for example, the broadcast content providing apparatus 200 generates default CM video data that displays the current time as an animation.
<About distribution unit 208>
The distribution unit 208 distributes network distribution video data (S110). Since the process of distributing video data via a network is a known technique, a detailed description of this technique is omitted.
<About the playback device 300>
The playback device 300 plays back the network distribution video data distributed by the distribution unit 208. Here, since a technique for reproducing video data distributed via a network with various computers is a known technique, a detailed description of this technique is omitted.
<Modification>
The broadcast unit 204 may be provided in a device (hereinafter referred to as a broadcast device) different from the broadcast content providing device 200. In this case, the broadcast content providing apparatus 200 includes an output unit that outputs television broadcast video data to the broadcast apparatus. Then, the broadcasting device broadcasts the television broadcast video data acquired from the output unit. The output of the television broadcast video data from the broadcast content providing apparatus 200 to the broadcast apparatus may be performed via a network or may be performed via radio waves.
  Similarly, the distribution unit 208 may be provided in an apparatus (hereinafter referred to as distribution apparatus) different from the broadcast content providing apparatus 200. In this case, the broadcast content providing apparatus 200 includes an output unit that outputs network distribution video data to the distribution apparatus.

In FIG. 8, each block represents a functional unit configuration, not a hardware unit configuration. Except as described below, the broadcast content providing system 1000 according to the second embodiment has the same functions as the broadcast content providing system 1000 according to the first embodiment. In FIG. 8, the configuration of the broadcast content providing apparatus 200 is the same as that of FIG. 3, and thus the detailed configuration of the broadcast content providing apparatus 200 is omitted.
  The playback device 300 according to the second embodiment plays back the network distribution video data distributed by the distribution unit 208. However, the reproducing device 300 reproduces the network distribution CM video data acquired from the advertisement providing device 900 during the CM period when reproducing the network distribution video data. Here, the CM video data for network distribution is not included in the CM period of the network distribution video data distributed by the broadcast content providing apparatus 200.
  FIG. 9 is a diagram conceptually illustrating the operation of the broadcast content providing system 1000 according to the second embodiment. The playback device 300 acquires network distribution video data from the broadcast content providing device 200. Furthermore, the playback device 300 also acquires CM video data for network distribution from the advertisement providing device 900. Then, when reproducing the CM video data for network distribution, the reproducing apparatus 300 reproduces the CM video data for network distribution in the CM period. Note that the playback apparatus 300 only needs to play the network distribution CM video data during at least a part of the CM period, and does not need to play the network distribution CM video data at all times.
  In order to perform the above-described operation, the playback apparatus 300 includes a distribution video data acquisition unit 302, a playback unit 304, and a CM video data acquisition unit 306 as illustrated in FIG. Distribution video data acquisition unit 302 acquires network distribution video data from broadcast content providing apparatus 200. The CM video data acquisition unit 306 acquires CM video data for network distribution from the advertisement providing apparatus 900. The reproduction unit 304 reproduces network distribution video data. As described above, the playback unit 304 plays back the CM video data for network distribution during the CM period.
  The advertisement providing apparatus 900 includes a request acquisition unit 902 and a CM video data distribution unit 904. The request acquisition unit 902 receives a distribution request for CM video data for network distribution from the CM video data acquisition unit 306. The CM video data distribution unit 904 distributes the CM video data for network distribution to the CM video data acquisition unit 306 based on the distribution request.
<About Distribution Video Data Acquisition Unit 302>
The distribution video data acquisition unit 302 acquires network distribution video data distributed via the network. Since a method for acquiring video data distributed via a network is a known technique, a detailed description of this technique is omitted.
<About CM Video Data Acquisition Unit 306 and Advertisement Providing Device 900>
CM video data acquisition unit 306 acquires CM video data for network distribution from advertisement providing apparatus 900. In response to the distribution request from the CM video data acquisition unit 306, the advertisement providing apparatus 900 distributes the CM video data for network distribution to the CM video data acquisition unit 306. Note that the playback device 300 and the advertisement providing device 900 are connected via a network.
  In response to the distribution request received from the CM video data acquisition unit 306, the CM video data distribution unit 904 of the advertisement providing apparatus 900 determines CM video data for network distribution to be distributed to the CM video data acquisition unit 306. There are various determination methods. For example, the advertisement providing apparatus 900 provides CM video data for one network distribution selected at random. In addition, for example, the CM video data distribution unit 904 provides CM video data for network distribution that satisfies a predetermined condition indicated in the distribution request from the CM video data acquisition unit 306.
  The predetermined condition is, for example, the length of playback time of CM video data for network distribution. Hereinafter, the length of the reproduction time of the video data is also simply referred to as “video data length”. In this case, the advertisement providing apparatus 900 provides CM video data for network distribution having a predetermined length or less. Further, for example, the predetermined condition is a condition representing the user's preference. Hereinafter, information representing user preferences is referred to as preference information. In this case, the advertisement providing apparatus 900 distributes the CM video data for network distribution that matches the user's preference based on the preference information indicated in the distribution request. For example, the preference information is information about a Web page that the user has recently accessed, information about a video that has been viewed, or information about a downloaded application. The CM video data acquisition unit 306 generates preference information using a cookie such as a browser of the playback device 300, for example.
  The CM video data acquisition unit 306 may use a combination of the length of the CM video data and the user preference as the predetermined condition. In this case, the CM video data acquisition unit 306 distributes the CM video data for network distribution whose length is equal to or shorter than a predetermined time and matches the user's preference.
  The CM video data acquisition unit 306 starts acquiring the CM video data for network distribution at the timing when the playback position of the network distribution video data being played back by the playback unit 304 is at or immediately before the start of the CM period. . There are various methods for the CM video data acquisition unit 306 to recognize that the reproduction position of the network distribution video data is the start position of the CM period or immediately before it. For example, information indicating the start position of the CM period or the frame immediately before it is included in the metadata of the frame of the network distribution video data immediately before the start of the CM period. The CM video data acquisition unit 306 detects the start position of the CM period by detecting that this information is associated with the metadata of the frame played back by the playback unit 304.
  Further, for example, an identifier indicating whether the frame is related to the source video data or the default CM video data is included in the metadata of each frame of the network distribution video data. In this way, the CM video data acquisition unit 306 checks the identifier shown in the metadata of each frame that the playback unit 304 plays back, thereby starting the playback of the default CM video data (the CM period is Can be detected).
  The CM video data acquisition unit 306 may request 1) CM video data for network distribution from the advertisement providing apparatus 900 one by one, or 2) request a plurality of CM video data for network distribution at once. May be. Each case will be specifically described below.
<< 1) When requesting CM video data one by one >>
The CM video data acquisition unit 306 repeatedly requests CM video data for network distribution one by one until the CM period ends. When requesting each video data, the CM video data acquisition unit 306 requests video data having a length less than or equal to the remaining time until the CM period ends. Therefore, the playback device 300 further includes a CM total time acquisition unit 308. The CM total time acquisition unit 308 acquires the CM total time indicating the length of the CM period. FIG. 10 is a block diagram illustrating a playback apparatus 300 having a CM total time acquisition unit 308.
  For example, the total CM time is indicated in the metadata of the frame at the start position of each CM period in the network distribution video data or the metadata of the frame immediately before the frame. The CM total time acquisition unit 308 acquires the CM total time from the metadata of these frames. Further, for example, the CM total time acquisition unit 308 may request the broadcast content providing apparatus 200 to transmit information indicating the CM total time at the timing when it is understood that the CM period starts. Further, for example, information indicating the length of each CM period included in the network distribution video data may be added to the head of the network distribution video data. In this case, the CM total time acquisition unit 308 can acquire the length of each CM period before the reproduction of the network distribution video data is started (before the program starts).
  FIG. 11 is a first diagram conceptually illustrating the reproduction processing of network distribution video data. It is assumed that the network distribution video data is played back by the playback unit 304 and that the playback position becomes the start position of the CM period. The CM video data acquisition unit 306 distributes a distribution request for requesting a network distribution CM having a length equal to or shorter than the remaining time of the CM period (here, the total CM time) to the advertisement providing apparatus 900. In this distribution request, a time equal to or less than the remaining time of the CM period is indicated as a condition to be satisfied by the requested CM video data for network distribution. A specific method for determining the length of the requested CM video data for network distribution will be described later.
  The request acquisition unit 902 acquires the distribution request. The CM video data distribution unit 904 searches for CM video data for network distribution under the condition that the playback time is equal to or shorter than the time specified by the distribution request. Further, the CM video data distribution unit 904 determines NWCM1, which is one of the network distribution CM video data satisfying the above conditions, as the network distribution CM video data to be distributed to the playback device 300. Then, the CM video data distribution unit 904 distributes NWCM1 to the playback device 300.
  As a result of processing by the advertisement providing apparatus 900, the CM video data acquisition unit 306 acquires NWCM1. Then, the playback unit 304 plays back this NWCM1.
  When the playback of the NWCM1 by the playback unit 304 ends, the CM video data acquisition unit 306 calculates the remaining time of the CM period and provides a distribution request for requesting a CM for network distribution with a length equal to or shorter than the calculated remaining time. To device 900. The advertisement providing apparatus 900 distributes NWCM2 to the playback apparatus 300 by the same processing as the distribution of NWCM1. The CM video data acquisition unit 306 acquires NWCM2 from the advertisement providing apparatus 900. The playback unit 304 plays back NWCM2.
  Thereafter, similarly, NWCM3 and NWCM4 are acquired and played back in order. At the end of the CM period, the playback unit 304 plays back the network distribution video data from the end position of the CM period (the start position of the next main part).
  FIG. 12 is a flowchart illustrating the flow of processing executed in the CM period by the playback device 300 that requests CM video data for network distribution one by one. The CM video data acquisition unit 306 requests the advertisement providing apparatus 900 to distribute CM video data for network distribution having a length equal to or shorter than the CM remaining time (S202). The playback unit 304 plays back default CM video data (S204). The reproduction of the default CM video data is performed before the reproduction of the CM video data for network distribution is started in S210 described later.
  The CM video data acquisition unit 306 acquires a response from the advertisement providing apparatus 900 (S206). Based on the content of the response, the CM video data acquisition unit 306 determines whether CM video data for network distribution has been acquired (S208). When the CM video data for network distribution can be acquired (S208: YES), the process of FIG. 12 proceeds to S210. On the other hand, when the CM video data for network distribution cannot be acquired (S208: NO), the process of FIG. 12 proceeds to S212.
  In S210, the playback unit 304 plays back the CM video data for network distribution. Thereafter, the process of FIG. 12 proceeds to S202 again.
  In S212, the playback unit 304 plays back the default CM video data until the CM period ends.
<<<< Default CM Video Data Playback >>>>
Here, as shown in FIG. 11, after the CM video data acquisition unit 306 requests CM video data for network distribution, the playback unit 304 starts to reproduce the CM video data for network distribution. There is a delay. During this delay, the playback unit 304 plays back default CM video data included in the network distribution video data. In this way, because the default CM video data is inserted in the network distribution video data, not the CM video data for TV broadcasting, even if there is a time during which the CM video data for network distribution cannot be played back, Video with less discomfort is output.
  As shown in FIG. 11, there may be a plurality of sections in which default CM video data is reproduced in one CM period. In this case, the playback unit 304 may playback 1) default CM video data from the playback position corresponding to the point at which playback of the CM video data for network distribution ends, or 2) playback of the previous default CM video data. Playback of default CM video data may be resumed from the position where it was stopped.
  FIG. 13 is a diagram illustrating the difference in the playback method of default CM video data. FIG. 13A illustrates the case of 1) above. In FIG. 13A, since the CM video data for network distribution is reproduced from the time t2 to the time t3, the reproduction of the default CM video data is stopped. Then, the playback unit 304 plays back the default CM video data from the playback position corresponding to the time t3 (the position when t3-t1 has elapsed from the beginning) at the time t3. In this case, the portion of the default CM video data corresponding to the time t2 to t3 is skipped and is not played back.
  On the other hand, in the case of FIG. 13B, the playback unit 304 starts playback from the position where playback of default CM video data is stopped (position corresponding to time t2) at time t3. According to this method, since the reproduction of the default CM video data is resumed from the point where it was interrupted, the default CM video data is not skipped halfway.
<<< Acquisition and playback timing of CM video data for network distribution >>>
When playing the CM video data for network distribution, the playback unit 304 starts playback at the stage of acquiring a part of the data (so-called streaming) rather than starting playback after acquiring all of the video data. It is preferable to perform regeneration.
<<< Length of CM video data for network distribution >>>
As described above, there is a delay between the CM video data acquisition unit 306 requesting and acquiring the CM video data for network distribution. Therefore, it is preferable that the CM video data acquisition unit 306 acquires CM video data for network distribution having a length shorter than the remaining time of the CM period.
For example, the CM video data acquisition unit 306 determines the length of the CM video data for network distribution to be acquired by the following formula (1). L NWCM represents the length of the acquired CM video data for network distribution, and R CM represents the remaining time of the CM period.
  When the value of a is larger than 0, the length of the CM video data for network distribution becomes shorter than the remaining time of the CM period. For example, the value of a is determined in consideration of the time required to acquire CM video data for network distribution.
  The value of a may be a statically determined value or a dynamically determined value. In the former case, for example, the value of a is a value set in advance by the administrator of the broadcast content providing system 1000 or the user of the playback device 300 and is stored in a storage device accessible from the playback device 300. In the latter case, for example, the CM video data acquisition unit 306 determines the value of a based on the delay time when acquiring CM video data for network distribution in the past. For example, the CM video data acquisition unit 306 uses the value of a as the delay time when the CM video data for network distribution was acquired last time. Also, for example, the CM video data acquisition unit 306 uses a statistical value (average value, maximum value, etc.) of delay time for CM video data for each network distribution acquired so far in the current CM period as a value. Also good.
<<< Timing for acquiring CM video data for network distribution >>>
The CM video data acquisition unit 306 may start acquiring the next CM video data for network distribution before the reproduction unit 304 completes the reproduction of the CM video data for network distribution. As described above, there is a delay in acquiring the CM video data for network distribution. Thus, requesting the next CM video data for network distribution earlier can reduce the influence of the delay. it can. For example, the CM video data acquisition unit 306 makes a request for requesting the next CM video data for network distribution to the advertisement providing apparatus 900 at a timing when the remaining time of the CM video data for network distribution being played reaches a predetermined value. Send.
  This predetermined value may be a statically determined value or a dynamically determined value. In the former case, this predetermined value is stored in advance in a storage device accessible from the CM video data acquisition unit 306. In the latter case, for example, this predetermined value is determined based on the delay time when the CM video data for network distribution is acquired in the past, like the value of a in Equation (1) described above.
  The CM video data acquisition unit 306 may transmit a request for requesting CM video data for network distribution before the reproduction position of the network distribution video data enters the CM period. By doing so, it is possible to shorten the time from the start of the CM period until the start of playback of CM video data for network distribution.
  In this case, for example, information indicating a reproduction position where acquisition of CM video data for network distribution is to be started is included in the metadata of a frame a predetermined time before the start position of the CM period. The CM video data acquisition unit 306 performs processing for acquiring CM video data for network distribution at the timing when it is detected that this information is included in the metadata of the frame of the network distribution video data reproduced by the reproduction unit 304. Start.
<< 2) When requesting multiple CM video data at once >>
The CM video data acquisition unit 306 may acquire a plurality of CM video data for network distribution at a time. Specifically, the CM video data acquisition unit 306 transmits a distribution request for requesting a plurality of CM video data for network distribution to the advertisement providing apparatus 900. In response to this distribution request, the CM video data distribution unit 904 of the advertisement providing apparatus 900 determines a plurality of CM video data for network distribution to be provided to the playback apparatus 300 and sequentially provides them to the playback apparatus 300. Note that, as described above, the playback unit 304 may start playback of network video CM video data before all of the requested network video CM data is acquired.
  The CM video data acquisition unit 306 preferably acquires a plurality of CM video data for network distribution so that the total length is equal to or less than the total CM time. In this case, the playback device 300 includes the CM total time acquisition unit 308 described above.
  FIG. 14 is a second diagram conceptually illustrating the reproduction processing of network distribution video data. It is assumed that the network distribution video data is played back by the playback unit 304 and that the playback position becomes the start position of the CM period. The CM video data acquisition unit 306 transmits a request for requesting a plurality of CMs for network distribution having a length equal to or shorter than the total CM time to the advertisement providing apparatus 900. The advertisement providing apparatus 900 delivers a plurality of CM video data (NWCM1 to NWCM4) for network delivery whose total length is equal to or less than the total CM time. The playback unit 304 plays back NWCM1 to NWCM4 in order.
  FIG. 15 is a flowchart illustrating the flow of processing executed in the CM period by the playback device 300 that requests a plurality of CM video data for network distribution at a time. The CM video data acquisition unit 306 requests the advertisement providing apparatus 900 to distribute a plurality of CM video data for network distribution whose total time is equal to or shorter than the total CM time (S302). The playback unit 304 plays back default CM video data (S304). The reproduction of the default CM video data is performed until the reproduction of the CM video data for network distribution is started in S310 described later.
  The CM video data acquisition unit 306 acquires a response from the advertisement providing apparatus 900 (S306). Based on the content of the response, the CM video data acquisition unit 306 determines whether CM video data for network distribution has been acquired (S308). When the CM video data for network distribution can be acquired (S308: YES), the process of FIG. 15 proceeds to S310. On the other hand, when CM video data for network distribution cannot be acquired (S308: NO), the process of FIG. 15 proceeds to S312.
  In S310, the reproduction unit 304 sequentially reproduces the acquired plurality of CM video data for network distribution (S310).
  In S312, the reproducing unit 304 reproduces default CM video data until the CM period ends (S312).
  The CM video data acquisition unit 306 may make a distribution request for CM video data for network distribution to the advertisement providing apparatus 900 a plurality of times. In this case, the process of FIG. 15 proceeds to S302 after S310. However, in this case, the total time of the CM video data for network distribution requested in S302 is not longer than the remaining time of the CM period. By requesting CM video data for network delivery multiple times in this way, for example, the CM video data acquisition unit 306 sets the total time of CM video data for network delivery requested in consideration of the delay to make a delivery request. However, if the delay time is shorter than expected, additional CM video data for network distribution can be acquired and played back. Therefore, it is possible to increase the length of reproduction of CM video data for network distribution.
  Due to the influence of delay in acquiring CM video data for network distribution, the acquired CM video data for network distribution may not be fully replayed within the CM period. In this case, for example, the playback unit 304 performs processing so that the playback of the CM video data for network distribution is not stopped halfway. Specifically, in step S310, the reproduction unit 304 determines that the length of the network distribution CM video data to be reproduced is equal to or less than the remaining time of the CM period before reproducing each network distribution CM video data. Check whether or not. If the length of the CM video data for network distribution is less than or equal to the remaining time of the CM period, the execution of S310 is continued. If the length of the CM video data for network distribution is longer than the remaining time of the CM period, A similar check is performed for CM video data for network distribution. If the length of any CM video data for network distribution is longer than the remaining time of the CM period, the process of FIG. 15 proceeds to S312.
  However, the playback unit 304 plays the CM video data for network distribution until the end of the CM period, stops the playback of the CM video data for network distribution at the end of the CM period, and shifts to the playback of the source video data. May be.
  Note that there are various methods by which the CM video data distribution unit 904 determines the distribution order of a plurality of CM video data for network distribution. For example, the CM video data distribution unit 904 distributes CM video data for network distribution in a random order. Further, for example, the CM video data distribution unit 904 distributes the CM video data for network distribution in descending order of the degree of matching with the user's preference based on the above-described preference information.
  The CM video data acquisition unit 306 may acquire a plurality of CM video data for network distribution without considering the total CM time. In this case, the total time of network distribution CM video data for requesting distribution to the advertisement providing apparatus 900 is determined in advance as a set value. In this case, the playback device 300 may not have the CM total time acquisition unit 308.
<About the playback unit 304>
The reproduction unit 304 needs to reproduce the network distribution video data from the position after completion of the CM period at the timing when the CM period ends. Therefore, the reproducing unit 304 needs to grasp the end point of the CM period. For example, the playback unit 304 sets a timer process to be executed after the CM total time has elapsed since the CM period started. In accordance with this timer process, the playback unit 304 plays back the network distribution video data from the position after the completion of the CM period. Here, the function of setting the timer process is implemented in, for example, an OS that operates on the playback device 300.

  The organization that owns the advertisement providing device 900 may be the same as 1) the organization that owns the broadcast content providing device 200, or 2) may be different. In the case of 1), for example, a television station owns both the advertisement providing apparatus 900 and the broadcast content providing apparatus 200. On the other hand, 2) For example, a television station owns the broadcast content providing apparatus 200, and an advertising company owns the advertisement providing apparatus 900.
  FIG. 18 is a diagram exemplifying the owners of the devices constituting the broadcast content providing system 1000. FIG. 18A illustrates the case of 1) above. Specifically, both the broadcast content providing apparatus 200 and the advertisement providing apparatus 900 are owned by a television station.

<Action and effect>
According to the broadcast content providing system 1000 of the present embodiment, similar to the broadcast content providing system 1000 of the first embodiment, the video of the broadcast content portion is shared between the video broadcast on the television and the video distributed on the network. However, the video of the CM part can be different.
  Furthermore, the playback device 300 of the broadcast content providing system 1000 according to the present embodiment has CM video data (CM video data for network distribution) other than the CM video data for network distribution distributed by the broadcast content providing device 200 in the CM period. ) Can be played. Therefore, it becomes easy to give variations to CMs played back by the playback device 300. Further, if the advertisement providing device 900 provides the playback device 300 with CM video data for network distribution that matches the preference of the playback device 300, the user of the playback device 300 views a CM that suits his / her preference. become able to. Therefore, the video reproduced by the reproduction device 300 becomes more suitable for the user, and the satisfaction of the user who uses the reproduction device 300 is improved.
  Further, since the default CM video data is inserted in the network distribution video data reproduced by the playback apparatus 300 instead of the CM video data for television broadcasting, there is a time during which the CM video data for network distribution cannot be reproduced. However, CM video data for television broadcasting is not played back by the playback device 300. Therefore, according to the broadcast content providing system 1000 of the present embodiment, it is possible to reliably prevent CM video data for television broadcasting from being played back on the playback device 300.
[Embodiment 3]
FIG. 19 is a block diagram illustrating a broadcast content providing system 1000 according to the third embodiment. In FIG. 19, each block represents a functional unit configuration, not a hardware unit configuration.
  A broadcast content providing system 1000 according to the third embodiment includes a broadcast content providing apparatus 400 and a playback apparatus 500. The broadcast content providing apparatus 400 differs from the broadcast content providing apparatus 200 of the first and second embodiments that distribute network distribution video data to the reproduction apparatus 300 via a network, and broadcast television broadcast video data to the reproduction apparatus 500 via a network. To deliver. Unlike the playback device 300 of the first and second embodiments that acquire and play network distribution video data, the playback device 500 acquires and plays back TV broadcast video data. However, when reproducing the television broadcast video data, the reproduction device 500 performs processes other than the reproduction of the television broadcast CM video data during the CM period.
  FIG. 20 is a diagram conceptually illustrating the operation of the broadcast content providing system 1000 according to the third embodiment. Broadcast content providing apparatus 400 uses television broadcast video data generated from source video data for both television broadcast and network distribution. The playback device 500 acquires television broadcast video data distributed over the network. The playback device 500 plays back TV broadcast video data. However, the playback device 500 performs processing other than playback of CM video data for television broadcasting during the CM period.
  In order to realize the above-described operation, the broadcast content providing apparatus 400 includes a broadcast video data generation unit 402 and a distribution unit 404. The broadcast video data generation unit 402 generates television method video data. The distribution unit 404 distributes the television broadcast video data to the playback device 500 via the network. Here, the broadcast video data generation unit 402 generates television broadcast video data by the same method as the broadcast video data generation unit 202 of the first embodiment. In addition, the distribution unit 404 distributes the network distribution video data to the reproduction device 500 in the same manner as the distribution unit 208 distributes the network distribution video data to the reproduction device 300.
  In order to realize the above-described operation, the playback device 500 includes a distribution video data acquisition unit 502 and a playback unit 504. Distribution video data acquisition unit 502 acquires television broadcast video data distributed by distribution unit 404. The playback unit 504 plays back TV broadcast video data. At this time, the playback unit 504 performs processes other than the playback of CM video data for television broadcasting during the CM period. The distribution video data acquisition unit 502 acquires the television broadcast video data by the same method as the distribution video data acquisition unit 302 of the second embodiment acquires the network distribution video data.
<About processing performed during the CM period>
Various processes are performed by the playback unit 504 during the CM period. For example, during the CM period, the playback unit 504 stops playback processing of television broadcast video data, displays a predetermined still image, plays back predetermined audio data, or plays video data other than CM video data for television broadcasting. Do. The predetermined still image is an arbitrary still image, for example, a white or black image. Here, the predetermined still image and the predetermined audio data are stored in advance in a storage device or the like accessible from the playback device 300.
  The above-mentioned “video data other than CM video data for television broadcasting” reproduced by the reproduction unit 504 during the CM period is arbitrary. Specific examples will be described below.
<< Specific Example 1 >>
The reproduction unit 504 acquires and reproduces CM video data (such as video data in which a predetermined still image is repeated) having the same content as the default CM video data described in the first embodiment during the CM period. There are various methods by which the playback device 300 acquires the CM video data. For example, the playback device 300 acquires the CM video data stored in advance in a storage device or the like accessible by the playback device 300. Further, for example, the playback device 300 may acquire the CM video data from the advertisement providing device 900. In this case, the advertisement providing apparatus 900 has a function of providing CM video data having the same content as the default CM video data in addition to the CM video data for network distribution. Further, for example, the playback device 300 may acquire the CM video data from the broadcast content providing device 200. For example, the broadcast content providing apparatus 200 distributes the CM video data to the playback apparatus 300 at the same time as or before the distribution of the source video data. The playback unit 304 plays back the acquired CM video data during each CM period.
  Note that the length of the CM video data may be shorter than the length of the CM period. In this case, the playback unit 304 repeatedly plays the CM video data until the CM period ends.
<< Specific Example 2 >>
The playback unit 504 plays back CM video data for network distribution during the CM period. The method for acquiring CM video data for network distribution is as described in the second embodiment. In this case, the playback device 500 includes a CM video data acquisition unit 506 having the same function as the CM video data acquisition unit 306 of the second embodiment. In this case, the broadcast content providing system 1000 includes an advertisement providing apparatus 900.
  Here, as described in the second embodiment, acquisition of CM video data for network distribution involves a delay. Therefore, the reproduction unit 504 stops the reproduction process of the television broadcast video data, displays a predetermined still image, reproduces the predetermined audio data, or default CM video until the reproduction of the CM video data for network distribution is started. Play CM video data with the same content as the data. For example, like the playback unit 304 of the second embodiment, the playback unit 504 plays back CM video data having the same content as the default CM video data until playback of CM video data for network distribution is started. After that, CM video data for network distribution is played back.
<Hardware Configuration Example of Broadcast Content Providing Device 400>
The broadcast content providing apparatus 400 of the third embodiment is realized using the computer 100 as in the first embodiment (see FIG. 5). In the present embodiment, the storage 108 described above includes a program module that implements each function described in the present embodiment.
<Example of Hardware Configuration of Playback Device 500>

[Embodiment 4]
FIG. 21 is a block diagram illustrating a broadcast content providing system 1000 according to the fourth embodiment. In FIG. 21, each block represents a functional unit configuration, not a hardware unit configuration.
  The broadcast content providing system 1000 according to the fourth embodiment includes a broadcast content providing apparatus 600 and a playback apparatus 700. Unlike the broadcast content providing apparatus 200 and the broadcast content providing apparatus 400, the broadcast content providing apparatus 600 according to the fourth embodiment transmits source video data (video data into which no CM video data is inserted) to the playback apparatus 700 via a network. To deliver. The playback device 700 plays back source video data. However, the playback device 700 performs processing other than playback of the source video data during the CM period.
  FIG. 22 is a diagram conceptually illustrating the operation of the broadcast content providing system 1000 according to the fourth embodiment. Broadcast content providing apparatus 600 distributes source video data to playback apparatus 700 via a network. The playback device 700 plays back the distributed source video data. However, the playback device 700 performs processing other than playback of the source video data during the CM period. The television broadcast video data to be broadcasted on the television is generated from the source video data and the television broadcast CM video data as in the first embodiment.
  In order to realize the above-described operation, the broadcast content providing apparatus 600 includes a distribution unit 602. The distribution unit 602 distributes the source video data to the playback device 700 via the network. The distribution unit 602 distributes the source video data to the reproduction device 700 in the same manner as the distribution unit 208 distributes the network distribution video data to the reproduction device 300.
  In order to realize the above-described operation, the playback device 700 includes a distribution video data acquisition unit 702 and a playback unit 704. The distribution video data acquisition unit 702 acquires source video data distributed by the distribution unit 602. The playback unit 704 plays back the source video data.
  The distribution video data acquisition unit 702 acquires the source video data in the same manner as the distribution video data acquisition unit 302 acquires the network distribution video data.
  The reproduction unit 704 grasps the start time of the CM period in the same manner as the reproduction unit 304 of the second embodiment grasps the start time of the CM period.
  There are various methods for the playback unit 704 to grasp the end point of the CM period. For example, the playback unit 704 sets the time when the total CM time has elapsed since the start of the CM period as the end of the CM period. In this case, the playback device 700 has a CM total time acquisition unit 706. The CM total time acquisition unit 706 has the same function as the CM total time acquisition unit 308 of the second embodiment. Further, for example, the playback unit 704 may acquire information indicating the end of the CM period from the broadcast content providing apparatus 600. In this case, the playback unit 704 sets the time when this information is received as the end time of the CM period.
  “Processing other than playback of source video data” performed by the playback unit 704 in the CM period is similar to “processing other than playback of CM video data for television broadcasting” performed by the playback unit 504 of the third embodiment during the CM period. It is. Note that when the playback unit 704 plays back CM video data for network distribution, the playback device 700 further includes a CM video data acquisition unit 708. In this case, the broadcast content providing system 1000 includes an advertisement providing apparatus 900. The CM video data acquisition unit 708 has the same function as the CM video data acquisition unit 306 of the second embodiment and the CM video data acquisition unit 506 of the third embodiment.
<Action and effect>
According to the broadcast content providing system 1000 of the present embodiment, similar to the broadcast content providing system 1000 of the first embodiment, the video of the broadcast content portion is shared between the video broadcast on the television and the video distributed on the network. However, the video of the CM part can be different.
  Furthermore, since the CM video data is not included in the video data distributed from the broadcast content providing apparatus 600 of the present embodiment to the playback apparatus 700, the size of the video data distributed via the network is reduced. Therefore, the load on the network for distributing video data is reduced. Further, by not distributing to the playback device 700 video data that is not played back by the playback device 700 (such as CM video data for TV broadcasting), waste of network bandwidth and computer resources of the playback device 700 may occur. Can be prevented.
