Embodiment Construction

[0035] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0036] Such as figure 1 Shown is a structural principle block diagram of the system of the present invention. The system of the present invention includes a control module 1 , a video frame picture data acquisition module 2 , a frame image block division module 3 and a CRC check module 4 .

[0037] The video frame picture data acquisition module 2 decodes the input video information, and then captures the decoded video data, thereby obtaining continuous video frame picture data, and sends related information to the control module 1 . Wherein, when decoding the video information, any decoding technology can be used, and then the decoded video data can be captured by u...

Abstract

The invention discloses a video static frame detection system based on CRC check and a method thereof. The system comprises a video frame picture data acquisition module which is used for decoding video information so as to acquire continuous video frame picture data; a frame image block division module which is used for dividing each video frame picture into multiple frame image blocks; a CRC check module which is used for performing CRC checking on each frame image block so as to acquire a corresponding CRC check value; and a control module which determines whether the frame image block is a static frame image block based on the CRC check value, determines whether the frame picture is a static frame picture according to the number of the static frame image blocks and determines existence of a static frame fault according to the number of continuous static frame pictures. Algorithm performance is simple, resource occupation is low and performance efficiency is high so that performance time of video static frame detection is shortened, the static frames can be accurately detected and detection efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of broadcasting and television, in particular to a video still frame detection system and method based on CRC check. Background technique [0002] At present, with the rapid development of the radio and television industry and the continuous acceleration of the digitalization process, the situation of safe broadcasting has become more and more serious. In the broadcasting of digital TV, various broadcasting anomalies usually appear, such as black field, color field, color bar, still frame and so on. There are many reasons for these broadcast failures, usually hardware system failures, such as receiver failures, or software system failures, such as abnormal code stream transmission. With the increase in the number of programs, manual detection can no longer meet the requirements, and people have developed various methods of video quality monitoring. Among the various anomalies mentioned above, video freeze ...
