    摘要: Apparatus that compresses video data using a compression coder having control registers loaded with compression parameters, the apparatus being controlled to sense the size of compressed video data resulting from compressing a portion of source video data using a set of compression parameters, to automatically reload compression parameters that change as a function of the sensed size of compressed video data (the changed parameters being used with the next portion of video data to be compressed), and to store with each compressed portion an indication of the compression parameters used in compressing the portion.
