ABSTRACT:
Video data is managed in units of management blocks set in a storage area of a storage device. An access to the storage device is made in an access unit obtained for each video according to an encoding rate, etc. Additionally, a video is recorded so that only video data of the same program is recorded in one management block. As a result, an empty area can be prevented from being fragmented, and videos can be recorded even if the video data are recorded/reproduced at different encoding rates from a plurality of channels.
