FIG. 1 generally shows a broadcast service communication network distribution system 100 for a main broadcast station and a broadcast service communication network distribution system 200 for a subordinate broadcast station according to a first embodiment of the present invention. A main broadcasting station (headquarters station or key station) supplies part of its broadcast programs to subordinate broadcasting stations, and is sometimes called a distribution source station. A subsidiary broadcasting station (regional station) receives a portion of broadcast programs from the main broadcasting station, and is sometimes referred to as a distribution destination station. A broadcast service communications network distribution system is sometimes simply referred to as a communications network distribution system.

In FIG. 1, a communication network distribution system 100 of a main broadcasting station (headquarters station or key station) consists of a device group on the broadcasting station premises facility 100A side and a device group on the cloud 100B side. 110, browser system 180, TS reception section 120 of cloud 100B, broadcast signal decoding section 130, lid covering section 140, video file encoding section 150, SI/EPG extraction section 160, programming information storage section 170, programming control information user interface 190.

The TS transmitter 110 extracts a TS stream from a broadcast signal, for example, a DVB-ASI signal, from the broadcast equipment 101 of the main broadcast station and transmits IP packets using the IDP/IP protocol. Instead of the TS transmitter 110, equipment for transmitting SDI broadcast signals may be used. Regarding IP transmission of TS streams, for example, see Pro-MPEG Code of Practice #3 release 2, July 2004, "Transmission of Professional MPEG-2 Transport Streams over IP Networks", but is not limited thereto. The TS receiving unit 120 receives, for example, an IP packet and extracts a TS stream. The broadcast signal decoding unit 130 demultiplexes the TS stream to generate a video stream and an audio stream, and further performs MPEG decoding to generate a video/audio signal. The lid covering unit 140 covers the video/audio signals based on the programming information (including covering information) in the programming information storage unit 170. The video file encoding unit 150 receives the video/audio signal after the lid covering process, forms a video file using, for example, an HTTP distribution method (typically HLS method, HTTP Live Streaming, Apple Inc.), and responds to a user's request. transfer the file to the user based on the program so that the user can watch the program. The SI/EPG extraction unit 160 receives the TS stream from the TS reception unit 120, extracts SI (service information), extracts the SI or EPG (electronic program guide), and stores the programming information in the programming information storage unit 170. to be memorized. An operator at the equipment of the main broadcasting station operates the browser system 180 and inputs programming information via the programming control information user interface 190. The operator may input programming information based on the SI/EPG obtained by the SI/EPG extraction section 160. However, SI/EPG information only includes information about the entire program, does not distinguish between the main program and accompanying auxiliary frames (program promotion frame, information frame, commercial frame), and also does not distinguish between the program itself and accompanying auxiliary frames (program promotion frame, information frame, commercial frame) Do not distinguish between inappropriate parts. The operator inputs such lid covering information via the organization control information user interface 190.

The distribution method is not limited to the HTTP distribution method. Furthermore, instead of the HLS method, the MPEG-DASH method, Smooth Streaming (Microsoft Corporation), or HTTP Dynamic Streaming (Adobe Systems Corporation) may be used. Various methods other than HTTP protocol distribution, such as RTS (Real Time Streaming Protocol) and RTMP (Real Time Messaging Protocol), may be employed.

Note that it is optional whether or not to cover the auxiliary frames (program promotion frame, information frame, commercial frame) that accompany the main program (main program).
