Problems solved by technology

In the existing TV station broadcast program system, if the program has been associated with the program list after the review is passed, and the video and audio content of the program has been edited, but the program number remains unchanged, under the existing review method , it is impossible to find that the video and audio content of the program has been tampered with, but the program is still considered legal, but in fact the content of the program is already illegal. If it is played, it will cause security problems

Embodiment Construction

[0042] The basic idea of ​​the present invention is to extract the key frame of the corresponding program according to the text program list, and associate the text program list with the corresponding key frame. Before the program is played, according to the program number in the text program list, the verification frame of the corresponding program is extracted in the video server unit, and compared with the key frame of the program, it is checked whether the program is safe, and corresponding checks are carried out according to the detection results. deal with. By adopting the method of the invention, the safety of the broadcast program can be detected in real time, and the safety guarantee of the broadcast program content is strengthened.

[0043] The program playing system of the present invention will be specifically described below in conjunction with the accompanying drawings. Such as figure 2 As shown, between the two dotted lines is the system of the present invent...

Abstract

The invention discloses a program playing system, which uses an image frame extraction module to extract the key frame of the program, associates the text content of the program with the extracted key frame; the image frame extraction module extracts the verification frame of the program, and the image frame comparison module The verification frame is compared with the saved key frame, and the comparison result is sent to the playback control unit, and played according to the playback control strategy. The invention also discloses a corresponding method. The key frame of the program is extracted and saved. Before the program is played, the verification frame of the program is extracted, compared with the saved key frame, and the program is controlled according to the comparison result and the play control strategy. The invention has a simple structure and can effectively guarantee the safety of broadcast programs.

Description

technical field [0001] The invention relates to radio and television broadcast control technology, in particular to a program playing method and system. Background technique [0002] With the rapid development of computer technology, in the field of radio and television broadcast control, the traditional analog broadcast system has been gradually replaced by the digital broadcast control system with hard disk and multimedia server as the core. At present, the system for broadcasting programs by TV stations is as follows: figure 1 Shown: After the program is uploaded to the video server unit 18, the image frame extraction module 14 extracts the image frames in each program according to the text program list, and checks the safety of the program. After the review is passed, the program is considered safe. The text program list editing module 10 associates the program with the text program list, edits the text program list, and stores it in the text program list storage module...
