Description

[Technical field]

[0001] The present embodiment relates to a broadcasting system, a broadcast program transmitting device, and a broadcasting method. [Background technology]

[0002] As part of efforts to create a barrier-free information environment, the current broadcasting system provides a service that broadcasts commentary audio on an audio subchannel for the blind. However, in breaking news services such as news flashes, the processing of converting breaking news content into audio is extremely difficult, so the service only displays the breaking news in text and sounds a chime to notify the user of the news. As a result, audio-only viewers (those who cannot see the screen (drivers, workers, etc.)), including the blind, can only hear the chime and are unable to understand the content of the breaking news.

[0004] As described above, in the audio provision method used in conventional broadcasting systems, when providing breaking news, it is extremely difficult to convert the contents of the news into audio, so all that is done is to display the text and sound a chime, which creates the problem that viewers who cannot see the display screen are unable to understand the contents of the news.

[0005] The present embodiment has been developed in consideration of the above-mentioned problems, and aims to provide a broadcasting system, a broadcast program transmission device, and a broadcasting method that can provide breaking news content by audio through simple processing so that even viewers who cannot see the display screen can understand the content of the breaking news when it is provided. [Means for solving the problem]

[0006] In order to solve the above problem, the broadcasting system according to the present embodiment transmits a program broadcast signal including a base video and a base audio. and transmits the sub-audio of the program broadcast signal on a sub-channel. In this case, the breaking news data is imported in text format and superimposed on the base video, and the breaking news data in text format is synthesized into voice.

[0009] Hereinafter, embodiments will be described with reference to the drawings.

[0010] (First embodiment) Fig. 1 is a block diagram showing the configuration of the transmission side of the broadcasting system according to the first embodiment. In Fig. 1, 11 is a transmission server. Under the control of an APC (Automatic Program Control System) 12, this transmission server 11 takes in a base video broadcast signal (program broadcast signal) of a specified program in an SDI (Serial Digital Interface) format, and sends it to an encoder (encoding) 13 via a video multiplexer 111 and an audio multiplexer 112. The program broadcast signal encoded by the encoder 13 is multiplexed with a data broadcast, SI / EPG, or other MPEG2-TS format signal by a MUX (Multiplexer) 14, and is modulated for transmission by a modulation device 15 before being output as a transmission signal.

[0011] When the breaking news text is input, the video multiplexer 111 generates a breaking news superimposition from the breaking news text to be superimposed on the video, and multiplexes it onto the base video of the program broadcast signal. Meanwhile, the breaking news text is sent to the voice synthesizer 16, where it is converted into a voice synthesis signal. This voice synthesizer 16 can be realized on-premise or as a cloud service. The breaking news voice synthesis signal generated here is sent to the voice multiplexer 112, where it is multiplexed onto the program broadcast signal together with a separately prepared chime voice file.

[0012] In the broadcasting system configured as above, the process of the transmission server when breaking news occurs will be described with reference to the flow chart shown in FIG. First, it is determined whether there is breaking news (step S11), and if there is breaking news, a voice synthesis signal created by instructing voice synthesis is taken in (step S12), and the signal is decoded (step S13), and then multiplexed onto the base voice of the program broadcast signal together with the chime voice file (step S14), completing the series of processes. For example, in the 1 / 2ch subchannel, the base voice and chime are multiplexed, and in the 3 / 4ch subchannel, the chime and breaking news voice are multiplexed onto the commentary voice.

[0013] According to the above configuration, the breaking news text is automatically multiplexed onto the video in the form of a breaking news superimposition, and is also synthesized into voice and outputted as a multiplexed audio, making it possible to provide the breaking news content by audio with relatively simple processing.

[0014] Second embodiment Fig. 3 is a block diagram showing the configuration of the transmission side of a broadcasting system according to the second embodiment. In Fig. 3, the same parts as in Fig. 1 are given the same reference numerals, and overlapping explanations will be omitted here.

[0015] 3, the transmission server 21 includes a video branding unit 211, an audio MIX unit 212, a storage unit 213, an audio creation unit 214, and an audio decoding unit 215, and operates on software based on the IP (Internet Protocol) system. The video branding unit 211 takes in program-based video (material data) transmitted via IP by an IPSW (IP switch, a so-called LAN) 22, and creates a branding video by writing text data from the storage unit 213 in a predetermined area of ​​the image. The video created here is output to the encoder 13 via the audio MIX unit 212 as a program broadcast signal.

[0016] The storage unit 213 retrieves and stores the breaking news text created by the breaking news text creation device 23. It also sends the breaking news text to an external voice synthesis device (on-premise or cloud service) 16 via a voice creation unit 214, and retrieves and stores a voice synthesis file of the breaking news text created by the voice synthesis device 16 via the voice creation unit 214. The stored breaking news text and its voice synthesis file can be checked at any time on the breaking news text preview device 24.

[0017] The breaking news text stored in the storage unit 213 is sent to the video branding unit 211, and the voice synthesis file is converted into an IP format voice file by the voice decoding unit 215, and then sent to the voice MIX unit 212 where it is mixed with the chime voice file.

[0018] In the broadcasting system configured as above, the process of the transmission server when breaking news occurs will be described with reference to the flow chart shown in FIG. First, input and storage processing of breaking news text is performed in cooperation with breaking news text creation device 23 (steps S21, S22). Whether breaking news text has been stored is determined (step S23), and if it has been stored, the creation of breaking news voice is instructed, a voice synthesis file of the breaking news text is created in cooperation with voice synthesis device 16 (steps S24, S25), and stored in storage unit 213. If necessary, the stored voice synthesis file is confirmed by breaking news preview device 24 (steps S26, S27).

[0019] Here, an instruction to output the breaking news audio is awaited (step S28), and if there is no output instruction, the process returns to step S24, and if there is an instruction to output the breaking news audio, the breaking news audio file is read from the storage unit 213 and decoded (step S29), and the chime audio and the breaking news audio are multiplexed (mixed) onto the base audio and output (step S30), ending the series of processes. For example, in the 1 / 2ch subchannel, the base audio and chime are multiplexed, and in the 3 / 4ch subchannel, the chime and breaking news audio are multiplexed onto the commentary audio.

[0020] With the above configuration, it is possible to receive breaking news supers in text format, so the breaking news text is converted into audio and files, and the contents of the breaking news are mixed into the audio. This makes it possible to provide the breaking news in audio format following the chime sound, allowing people, including those with visual impairments, to understand what is happening even when they cannot see the display screen.

[0021] The present invention is not limited to the above-described embodiment as it is, and the components can be modified and embodied in the implementation stage without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining the multiple components disclosed in the above-described embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, components from different embodiments may be appropriately combined.
