Problems solved by technology

Since there are many kinds of programs and playing media at present, in fact, each channel is often equipped with two multi-media playing devices. However, in actual use, it is rarely necessary to use media playing devices. Each channel is equipped with separate media playback equipment, and there are disadvantages such as a large waste of equipment, complex systems, and difficult maintenance.

Embodiment 1

[0052] This embodiment is a method for dynamically allocating broadcast shared resources. The system used in the method is as follows: figure 1 shown. The system used in this embodiment includes: channel compilation workstation, message server, database, channel broadcast control workstation, shared scheduling device, shared control device, RS422 switcher, multiple media playback devices, multiple playback signal sources, X* Y switching matrix, the sharing control device includes: a master sharing control module and a backup sharing control module. figure 1 The thick solid line in the figure represents Gigabit Ethernet, the thin solid line represents the transmission of broadcast signals, the dotted line represents the transmission of control signals, the thin dotted line represents heartbeat, and the thick dotted line represents GPI signal transmission. It should be noted that figure 1 Only 3 media playback devices, 3 RS422 signal lines, and 5 playback output terminals C...

Embodiment 2

[0078] This embodiment is an improvement of Embodiment 1, and is a refinement of Embodiment 1 about the "steps of logical verification". The "steps of logical verification" described in this embodiment include the following sub-steps:

[0079] It is judged whether the medium of the program to be played is a traditional video tape. If yes, enter the "manual comparison and verification sub-step"; if not, enter the "automatic comparison and verification sub-step"

[0080] Manual comparison and verification sub-step: if the medium of the program to be broadcast is a traditional video tape, the comparison and verification work is completed manually; after the verification is completed, enter the "comparison and verification result processing sub-step";

[0081] Sub-step of automatic comparison and verification: if the medium of the program to be broadcast is a P2 card, Blu-ray disc, or easy-view card, the comparison and verification is automatically completed by the sharing schedul...

Embodiment 3

[0096] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment about "the steps of normal broadcasting". The "normal broadcasting steps" described in this embodiment include the following sub-steps, such as Figure 5 Shown:

[0097] The channel broadcast control workstation loads the program list, and according to the shared scheduling results, asks the shared control device whether the media broadcast equipment to be broadcast is ready for a certain time before the broadcast. If "No", an alarm prompt will be generated, and if "Yes", it will enter next sub-step;

[0098] After obtaining the ready information of the media playback device, the channel broadcast control workstation sends a playback control command;

[0099] After receiving the control instruction, the shared control device controls the corresponding media playing device to play through the RS422 serial port, and returns the status of the media playing device in rea...

Abstract

The invention relates to a method for dynamically distributing broadcast shared resources. The method comprises the following steps of: a step of distributing and scheduling the shared resources; a step of logically checking; a step of normally broadcasting; and a step of changing shared program information. According to the invention, a mode of carrying out centralized control by a medium video recorder is adopted to complete broadcasting of each channel under the urgency and emergency conditions; and compared with a conventional scheme of separately configuring medium play equipment for each channel, the method has the advantage of saving the investment of equipment resources. Moreover, due to the adoption of the uniform scheduling and control of the shared resources, the dynamic distribution of the resources is implemented, the using efficiency of the equipment is effectively improved, the system investment is reduced, the aim of balancing an equipment load is fulfilled and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to a method for dynamically allocating broadcast shared resources, which is a method used in a computer network of a broadcast television system and a method for broadcast control. Background technique [0002] In the traditional broadcasting system, it mainly depends on the video recorder, which is a tape-based playback device, to control the broadcasting according to the time sequence arranged by the program list. However, with the continuous development of computer technology, mechanical broadcasting equipment such as video recorders has been replaced by professional video servers. The main broadcasting business of TV stations is mainly undertaken by video servers. The uploading department files the tape programs in advance, and the collected programs After the files have been reviewed, they are migrated to the broadcast server, and finally the broadcast controller controls the video server to complete the broadcast according t...
