Problems solved by technology
Although the digital and networked document review process has greatly improved the efficiency of review, there are still problems: technical review is still in the state of manual review
The technical review is different from the content review. During the technical review, the reviewers need to carefully review the film from beginning to end, and if necessary, play and check frame by frame, which is very inefficient.
Due to the manual technical review, some image problems are difficult to distinguish with the naked eye, requiring the reviewers to concentrate
Therefore, manual technical review is not only annoying, but also very easy to miss

The invention discloses an audio and video technical examination method, which includes the following steps: S1: parameter configuration: configuring the duration of badness detected by each item, the value range of each item, and a collection of various color bar samples; S2: configuring audio and video files Carry out block division; S3: Carry out different item detection for different blocks, and exchange the detection items for detection after the detection is completed; S4: According to the detection results, send a report of the abnormal position and type of audio and video. The method of the present invention can set the parameters of technical examination items according to audio and video requirements, and at the same time select technical examination items according to audio and video requirements, and generate an inspection report including abnormal audio and video positions and abnormal types after technical examination, which is more beneficial Repair the video and audio, change the face of the video and divide it into blocks for detection, effectively improve the detection efficiency and save the time of technical review.
Description
technical field [0001] The invention relates to an audio and video technical examination method. Background technique [0002] During or after the production of digital TV programs, it is necessary to review its content, image and sound quality, which is called film review. The review of image and sound quality is called technical review, or technical review for short. The program review process of traditional TV stations is in a very primitive state: After the program producers complete the program production, they send the program tapes to the reviewers. The reviewer uses a special video recorder for the TV station to play the program tape, watches the output screen through the monitor, and conducts program review during the playback process. The review comments shall be returned to the program production staff together with the program tape by dictation or signature. This process generally needs to be repeated several times before it can be completed. [0003] With th...
