ENCODING METHOD AND ENCODER OF ANIMATION

摘要

PROBLEM TO BE SOLVED: To solve a problem that many unused disk regions are generated when data is stored in a storage device in the unit of GOV with the fixed number of frames since activity of a video is greatly different depending on time and place when surveillance monitoring is targeted in the case of encoding animation data.

SOLUTION: The number of frames in a random access unit is varied according to data quantity and encoding control is performed so that multiples of the data quantity of the random access unit approach prescribed data quantity of the storage device. Thus, the unused regions of the disk are reduced and use efficiency of the storage device is enhanced. In addition, retrieval time in random access processing is stabilized and throughput of data transfer processing is enhanced.
