Abstract
The present invention provides an AV data recording apparatus and method that facilitate various processes concerning a recorded video, including continuous reproduction, digital transmission, file operation, partial deletion, and post-recording. The AV data recording apparatus divides an audio signal and a video signal into transport packets having a predetermined unit length, assembles a plurality of transport packets as one transport stream and executes recording. Accordingly, this invention enables managing whether a logical block is used or not, detecting a continuous data area comprising plural logical blocks that ensure realtime continuous reproduction, and determining logical block numbers of continuous data areas to be recorded. As a result, the transport stream is recorded continuously on a plurality of detected continuous data areas.
