Abstract: Japan Broadcasting Corporation is shifting to file-based systems for its television production and playout systems, including videotape recorders and editing machines. A variety of codecs and formats based on the material exchange format for broadcast equipment have been adopted. These include Motion Picture Experts Group 2 (MPEG-2) or advanced video coding and operational pattern 1a or atom. Video files need to be converted into the selected codec and format to operate efficiently. The quality of video and audio must be checked during this conversion process, because degradation and noise may occur. This paper describes equipment that can quickly convert files to multiple formats, as well as intelligently check the quality of video and audio during the conversion. The equipment automatically adjusts thresholds to detect anomalies in the video quality check, depending on the type of codec and the spatial frequency of each area. This can be done in less time than the actual video duration by optimizing the processing software.
