Abstract:
A video recording and playback equipment which plays video data of a program memorized in an MXF file without playback delay is provided. It has a receiver, an analyzer, a playback information table, a program data memory and a decoder. The receiver receives the MXF file which includes the video data and metadata including information about an identification tag to identify the video data and data size of the video data. The analyzer judges whether the data contained in the file is the video data. If it is the video data, the analyzer analyzes a memory location where the video data is memorized in the file and memorize it on the playback information table as playback information, and also memorize the file to the program data memory. Only the video data is played by the decoder from the file based on the playback information.
