Description

[Technical Field]

[0001] The present embodiment relates to a broadcasting / distribution system and a broadcasting / distribution method. [Background technology]

[0002] In recent years, there has been an increase in the amount of entertainment content, including the Olympics, sports, dramas, etc. In addition, consumer cameras have also been improving in image quality and decreasing in cost, making it possible to view entertainment from an increasingly diverse range of perspectives.

[0003] In contrast, with existing broadcasting, even if multi-channel content from multiple viewpoints is produced, the amount of content that can be simultaneously provided over a single line is generally limited to one. For example, in a baseball game broadcast, around 12 cameras are deployed, each capturing the target object simultaneously from a different viewpoint, but the images output from multiple cameras cannot be broadcast simultaneously, so the camera's image output is switched appropriately, or the images are combined into one image using picture-in-picture and broadcast on a single channel.

[0004] It would be beneficial for viewers to be able to select and watch multi-channel content from various perspectives according to their preferences, but with current broadcasting, viewers cannot watch content from perspectives other than the content being broadcast. While it is technically possible to simultaneously deliver multi-channel content by expanding the broadcasting station's facilities, this would increase the cost burden on the broadcasting station, making it unrealistic.

[0005] On the other hand, broadcasting stations are equipped with internet distribution facilities as ports for multi-channel broadcasting, but in reality, these facilities are not used for normal operations. Therefore, one possible broadcasting format is to use internet distribution facilities to distribute part of the multi-channel content (content related to the content currently being broadcast) over the internet in parallel with the content currently being broadcast. However, even if internet distribution is used, simultaneous distribution of a large amount of content inevitably increases the cost burden on a single broadcasting station.

[0007] As mentioned above, in conventional broadcasting systems, even if multi-channel content from multiple viewpoints is produced, the number of contents that can be broadcast simultaneously on a single line is basically limited to one, so viewers are unable to view content other than the viewpoint that is being broadcast. While it is technically possible to simultaneously distribute content from multiple viewpoints, this is not realistic as it would be costly for a single broadcasting station.

[0008] This embodiment has been developed in consideration of the above-mentioned problems, and aims to provide a broadcasting and distribution system and a broadcasting and distribution method that can simultaneously provide multi-channel content from multiple perspectives without imposing a large cost burden on a single broadcasting station. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the broadcasting and distribution system according to this embodiment includes a first broadcasting station and a second broadcasting station, each of which has a broadcast system and a distribution system via the Internet, wherein the first broadcasting station broadcasts program content in which multi-channel content consisting of content from a plurality of related channels is selectively edited over the broadcasting system, the second broadcasting station receives distribution and distribution of related content of an arbitrary channel from the multi-channel content, and distributes the distributed and distributed related content over the Internet in accordance with the program content broadcast from the first broadcasting station, and the first broadcasting station provides a user terminal receiving the program content by broadcasting and the related content by the Internet distribution with a program content and related content for selectively viewing the program content and the related content. The program data is multiplexed onto the broadcast of the program content and transmitted. do. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments will be described with reference to the drawings.

[0012] (First embodiment) Fig. 1 is a block diagram showing the overall configuration of a broadcasting and distribution system according to the first embodiment. In Fig. 1, 11 is a main broadcasting station (key station), 12-1 to 12-n are associated broadcasting stations (local stations belonging to the key station group), 13 is a terrestrial broadcasting network, 14 is an IP network, and 15 is a cloud server.

[0013] When main broadcasting station 11 receives n-channel content captured from different perspectives (e.g., video output from multiple cameras) as a multi-channel content program, it selectively switches the content of any channel using switch 111 and transmits it as a single-channel broadcast program to terrestrial broadcasting network 13. At the same time, it supplies the output of switch 111 to network distribution adapter 112. Network distribution adapter 112 is equipped with a distribution encoder, a Society of Cable Telecommunications Engineers (SCTE) processor, and a control computer, and is a converter that converts the input broadcast program content (broadcast data) into an SCTE signal and then converts it into a format for IP (Internet Protocol) distribution. The broadcast program content converted for IP distribution is distributed to viewer user terminals (mobile terminals, hybridcast-compatible TV receivers, etc.) via cloud server 15 connected to IP network 14.

[0014] The main broadcasting station 11 also includes an IP distributor 113 that distributes all or part of n-channel multi-channel content (hereinafter referred to as related content) related to the broadcast program content to a required number of systems, and a control unit 114 that controls the distribution process of the IP distributor 113. The related content distributed by the IP distributor 113 is supplied to one of the associated broadcasting stations 12-1 to 12-n via an IP network.

[0015] Each of the associated broadcast stations 12-1 to 12-n includes a master system 121 having an operating system 1211 and a non-operating system 1212, an IP gateway (IPGW) 122, and an internet distribution adapter 123. The master system 121 operates normal broadcasting using the operating system 1211, but also receives related content distributed from the main broadcast station 11 via the IPGW 122 using the non-operating system 1212, converts the distributed related content into a predetermined format, and sends it to the internet distribution adapter 123. The internet distribution adapter 123 further converts the related content from the non-operating system 1212 into a format for internet distribution, and distributes it to the viewer's user terminal (not shown) via a cloud server 15 on the IP network 14.

[0016] That is, the broadcasting and distribution system according to this embodiment distributes a plurality of contents related to currently aired program contents to one of n affiliated broadcasting stations 12-1 to 12-n. Main broadcasting station 11 selectively switches among arbitrary contents and transmits them to terrestrial broadcasting network 13, while simultaneously distributing the currently aired program contents over the Internet via IP network 14. Meanwhile, affiliated broadcasting stations 12-1 to 12-n utilize IP network 14 to distribute the distributed related contents over the Internet via cloud server 15.

[0017] In this way, in this embodiment, the equipment is secured in advance at each broadcasting station 11, 12-1 to 12-n, but the system parts that are not normally in operation (ports for multi-channel) are treated as a virtual platform, and the cloud server 15 of the IP network 14 is used to link broadcasting and online distribution.

[0018] Fig. 2 is a flowchart showing the processing procedure in the control unit 114 of the main broadcasting station 11 shown in Fig. 1. First, when the control unit 114 of the main broadcasting station 11 receives an instruction for multi-channel broadcasting (step S11), it requests the cooperating broadcasting stations 12-1 to 12-n for a broadcast slot for the IP sub-channel of the non-operation system 1212 (step S12), and reserves the number of multi-channels (step S13).

[0019] When the control unit 114 receives an instruction to start multi-channel broadcasting (step S14), it causes the main broadcasting station 11 to distribute the program content currently being broadcast online, and causes related multi-channel content to be distributed via IP to the associated broadcasting stations 12-1 to 12-n that have approved the broadcast slots (step S15). In response to this, it provides a hybridcast service to a hybridcast-compatible television or user terminal, allowing the user terminal to selectively display content distributed by data broadcasting from each broadcasting station (step S16). This allows the user terminal to receive the program content currently being broadcast online distributed from the main broadcasting station 11, and simultaneously receive related content distributed online from the associated broadcasting stations 12-1 to 12-n, and selectively play any content from among the multiple contents currently being broadcast via hybridcast.

[0020] The control unit 114 waits for an instruction to end the multi-channel broadcast (step S17), and upon receiving the instruction to end, stops the online distribution of the multi-channel broadcast of the broadcast content and related content (step S18), and ends the series of processes.

[0021] According to the above system configuration, multiple contents can be distributed in conjunction with broadcasts on multiple channels without large-scale expansion of facilities at individual broadcasting stations, and viewers can watch content on any channel according to their preferences.

[0022] In this case, it is possible to expect additional revenue in the form of viewing fees while paying the costs incurred up until now. It will also lead to more efficient facilities at affiliated broadcasting stations, resulting in cost benefits. Furthermore, while broadcasting stations have traditionally operated as a B2B (Business to Business) business, with revenues centered on commercials, by using viewer access logs as viewer data through multi-channel content distribution, i.e., secondary use data that directly connects viewers, it will be possible to build a B2C (Business to Consumer) market and develop data businesses (B2C businesses) tailored to viewer preferences.

[0023] Here, conventionally, one broadcasting station has created broadcast content from multiple input materials, broadcast it, and then distributed online content linked to the broadcast that utilizes materials not used in the original content.

[0024] In contrast, in this embodiment, rather than one broadcasting station independently carrying out broadcasting and online distribution, channels not being used by affiliated broadcasting stations such as local broadcasting stations are treated as cloud channels on cloud server 15, and online distribution is coordinated between main broadcasting station 11 and affiliated broadcasting stations 12-1 to 12-n, thereby distributing the costs required for maintenance by one broadcasting station to multiple broadcasting stations.

[0025] Figure 3 is a conceptual diagram showing the cloud configuration that realizes online distribution of one broadcasting station in the broadcasting and distribution system shown in Figure 1, and in particular shows an example of B2B business and B2C business through multi-channel content distribution at affiliated broadcasting stations.

[0026] 3, the master system 121 of the cooperating broadcast station 12-i operates broadcasting unchanged from before (including B2B business in which viewing results are provided and paid for) in the operational system 1211, receives advertising fees from advertisers, and provides the viewing results to the advertisers. In the non-operational system 1212, the video of the related content and its accompanying information are sent to the IP network 14 via the network distribution adapter 123.

[0027] A plurality of cloud servers are connected to the IP network 14 according to their functions. For example, there are provided a cloud server (hereinafter referred to as a replacement server) 200 that replaces commercials, a cloud server (hereinafter referred to as an ad server) 300 that cooperates with the replacement server 200 to provide target commercials in a spot (Spot X) based on viewing information from user terminals, and a cloud server (hereinafter referred to as an information server) 400 that generates secondary use data from viewing information and broadcast data to be inserted into content video and provides it as needed.

[0028] The replacement server 200 retrieves the video of the multi-channel content from the network distribution adapter 122, presents viewing information from the user terminal to the ad server 300, retrieves the target commercial for the spot (Spot X) based on the viewing information from the ad server 300, appropriately replaces it with the video of the distribution content, and provides it to the user terminal. The viewing results of the user terminal are registered in the information server 400 as viewing information.

[0029] The information server 400 collects and registers viewing information from user terminals that are recipients of multi-channel viewing content (broadcast data) distributed by broadcast station 12-n. The viewing information from the user terminals is then linked to the broadcast data to analyze viewer preferences, and secondary use in data business (B2C business) is promoted, thereby realizing the co-creation of new value between the broadcast station and the user. The information server 400 may also function as a billing server for secondary use.

[0030] FIG. 4 is a functional block diagram showing an example of the information server 400 shown in FIG. 3, and FIG. 5 is a flowchart showing the flow of data processing by the information server 400 shown in FIG.

[0031] In FIG. 4, the server 400 is a computer and includes a processor 401, a storage unit 402 such as a hard disk drive (HDD), a ROM (Read Only Memory) 403 and a RAM (Random Access Memory) 404, a communication unit 405, and an optical media drive 406.

[0032] The ROM 403 stores basic programs such as a Basic Input Output System (BIOS) and a Unified Extensible Firmware Interface (UEFI), various setting data, etc. The RAM 404 temporarily stores programs and data loaded from the storage unit 402.

[0033] The optical media drive 406 reads digital data recorded on a recording medium such as a CD-ROM 407. Various programs executed by the information server 400 are recorded on, for example, a CD-ROM 407 and distributed. The programs stored on the CD-ROM 407 are read by the optical media drive 406 and installed in the storage unit 402.

[0034] The communication unit 405 is an interface that enables access to a database 500 connected to the IP network 14, and interprets a protocol for communicating with, for example, a server on a cloud. The database 500 stores content data 501, such as broadcast content, metadata 502 associated with the content data 501, and secondary use data 503 generated by processing these data. The content data 501 and secondary use data 503 may both be in, for example, an MXF file format, which is advantageous for data distribution, and the metadata 502 may be data in, for example, a CSV format or a general-purpose text format.

[0035] The information server 400 can download various programs to be executed from other servers via the communication unit 405, for example, and install them in the storage unit 402. It can also download the latest programs from other servers via the communication unit 25 and update already installed programs.

[0036] The processor 401 is, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and executes an OS (Operating System) and various application programs.

[0037] The processor 401 also includes an application data creation unit 401a, a distribution unit 401b, and a conversion unit 401c as processing functions according to the embodiment. These functional blocks can be understood as processes that are generated when a program 402a stored in the storage unit 402 is loaded into the RAM 404 and executed. In other words, the program 402a causes the server 400 to operate as the application data creation unit 401a, the distribution unit 401b, and the conversion unit 401c.

[0038] The usage data creation unit 401a creates secondary usage data 503 for each pre-registered user according to the specifications requested by that user from the content data 501. In other words, the content data 501 is processed to create secondary usage data 503 for each user. If necessary, the usage data creation unit 401a also refers to the metadata 502 of the original content data 501 to prepare secondary usage data 503 according to the user's request.

[0039] For example, in the case of commercial content, metadata is the broadcast date and time of the commercial content. Other metadata may also include information about the product being promoted by the commercial content, the sponsor, the performers, the age, gender, and generation of the promotional target, the start and end times of the commercial broadcast, whether or not subtitles are present, the industry, the product name, the content, and the image resolution (low-res, HD, 4K, etc.). In particular, when handling data in MXF file format, both commercial content and program content are accompanied by detailed metadata. Metadata can also be understood as broadcast operation data for operating a broadcasting system.

[0040] The distribution unit 401b distributes the secondary use data 503 created by the use data creation unit 401a to the destination user. The conversion unit 401c converts broadcast data such as multi-channel content from a broadcast station into digital data with the consent of the broadcast station, to generate content data 501. It is not essential that the function of generating content data from broadcast data be provided as a function of the server 400. For example, the broadcast station may generate content data itself and upload it to the database 500. Alternatively, the function of the conversion unit 401c may be implemented in the database 500, making it available as a cloud service.

[0041] Furthermore, a billing server 600 may be provided on the IP network 14. The billing server 600 is responsible for processing billing for users registered with the service provider according to the required specifications of the secondary use data. For example, the user can be billed based on a flat-rate service (subscription format) according to the rank of the contract content.

[0042] 5 is a flowchart showing an example of a processing procedure by the information server 400. The information server 400 generates content data 501 from broadcast data stored in a broadcast station, for example, and stores the content data 501 in the database 500 (step S21). The information server 400 also creates secondary use data 503 for each registered user and stores the data in the database 500 (step S22). The information server 400 then distributes the secondary use data 503 to each user (step S23). The above processing procedure is repeatedly executed. Note that steps S21 to S23 do not have to be executed in this order, and some steps may be executed simultaneously in parallel.

[0043] As described above, the configuration according to this embodiment not only saves on equipment costs, but also makes it possible to secure the necessary channels when needed, and by effectively utilizing the facilities of affiliated broadcasting stations, it is possible to increase the number of online distribution channels according to the number of channels. Currently, local broadcasting stations are reluctant to use online distribution from the perspective of cost-effectiveness, but by adopting this embodiment, it becomes possible to rent out one of the cloud channels, which can be expected to develop not only B2B business but also B2C business, and can become a source of income that is commensurate with the cost.

[0044] (Second embodiment) Fig. 6 is a block diagram showing a specific configuration of a broadcasting and communication system including a relay van. In Fig. 6, 21 is a relay van, 22 is a main broadcasting station, 23-1 to 23-n are associated broadcasting stations, 24 is a satellite line, 25 and 26 are terrestrial broadcasting networks, 27 and 28 are IP networks, and 29 is a cloud server.

[0045] A plurality of cameras 211-1 to 211-m arranged at the site or the like are connected to the broadcast van 21. The video content captured by the cameras 211-1 to 211-m is sent to a switch 213 via IPGWs 212-1 to 212-m. The switch 213 switches between the plurality of video contents as appropriate, and this output becomes the program content. The program content generated by the switch 213 is superimposed with auxiliary data such as subtitles in a super superimposer 214, multiplexed with audio data in an audio mixer (MIX) 215, and then power-amplified in a transmitter 216 before being sent to the main broadcasting station 22 via a satellite line 24.

[0046] The main broadcasting station 22 receives program content from the satellite line 24 via the line system 221 and sends it to the master system 222. The master system 222 sends the received program content to the transmission system 223, which then transmits it to the terrestrial broadcasting network 25 as a single-channel broadcast program. At the same time, the program content currently being broadcast is supplied to the internet distribution adapter 224. The internet distribution adapter 224 converts the input broadcast program content (broadcast data) into an SCTE signal, and then converts it into a format for IP distribution. The broadcast program content converted for IP distribution is distributed to the viewer's user terminal (such as a mobile terminal or a hybridcast-compatible TV receiver) via a cloud server 29 connected to the IP network 28.

[0047] The broadcast van 21 also includes IPGWs 212-1 to 212-m that distribute all or part of n-channel multi-channel content related to the broadcast program content (hereinafter referred to as related content) to the required number of systems, and a control unit 217 that controls the distribution process of the IPGWs 212-1 to 212-m based on broadcast program information. The related content distributed by the IPGWs 212-1 to 212-m is supplied to one of the cooperating broadcast stations 23-1 to 23-n via the IP network 27.

[0048] The associated broadcasting station 23-1 (to 23-n) receives the related content from the relay station 21 through the IPGW 231 and selectively outputs it to an operating system or a non-operating system using a switch 232. The content output to the operating system is superimposed with auxiliary data such as subtitles by a super superimposer 233, multiplexed with audio data by an audio mixer (MIX) 234, and then power-amplified by a transmitter 235 before being sent to the terrestrial digital broadcasting network 26.

[0049] Meanwhile, the content output to the non-operating system by switch 232 has auxiliary data such as subtitles superimposed on it by super superimposer 236, audio data multiplexed by audio mixer (MIX) 237, and then power amplified by transmitter 238 and supplied to network distribution adapter 239. Network distribution adapter 239 is a converter that converts the input broadcast program content (broadcast data) into an SCTE signal and then converts it into a format for IP distribution. The broadcast program content converted for IP distribution is distributed to viewer user terminals (mobile terminals, hybridcast-compatible TV receivers, etc.) via cloud server 29 connected to IP network 28.

[0050] According to the broadcasting and distribution system configured as described above, multi-channel content is edited in OB van 21, and the program content broadcast from main broadcast station 22 is distributed over the Internet via cloud server 29. At the same time, multi-channel content is selectively distributed over IP from OB van 21 to affiliated broadcast stations 23-1 to 23-n, and then distributed over the Internet from affiliated broadcast stations 23-1 to 23-n via cloud server 29, allowing user terminals to view content of any channel. In this case, viewer access logs can be acquired by cloud server 29, making it possible to distribute information tailored to viewer preferences, enabling B2C business as a new data business. As described above, according to the broadcasting and distribution system of the above embodiment, the main broadcasting station selectively switches and broadcasts multi-channel content on the operating system, distributes the multi-channel content by channel to the non-operating systems of the main broadcasting station and affiliated broadcasting stations, and distributes the distributed channel content from the non-operating systems of the main broadcasting station and affiliated broadcasting stations via an IP network in conjunction with broadcasting. To achieve this, the system parts (ports for multi-channel broadcasting) that are installed but not normally used at each broadcasting station are treated as virtual platforms, and the IP network is used to link broadcasting and online distribution via hybrid casting.

[0051] This will allow content from any channel to be provided to users without a large-scale expansion of facilities. It will also enable the company to expect increased revenue in the form of viewing fees at the same cost as before, and will also lead to more efficient facilities at affiliated broadcasting stations, resulting in cost benefits.

[0052] Furthermore, while broadcasters have traditionally run a B2B business, primarily based on commercials, these broadcasts will enable them to build a B2C market that connects directly with viewers, and will also enable them to develop data businesses tailored to viewer preferences.

[0053] The present invention is not limited to the above-described embodiments, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be created by appropriately combining multiple components disclosed in the above-described embodiments. For example, some components may be omitted from all the components shown in the embodiments. Furthermore, components from different embodiments may be appropriately combined.
