Abstract
In a recording device, a playback buffer is provided between a TS decoder and an AV decoder and an internal memory is provided within the AV decoder. This being so, a video frame which is being played precedes a video frame which is being received, by about six frames. This time interval between reception and playback poses a problem when manual recording is performed. To solve the problem, the same video frames which are to be played by the AV decoder are stored in a record buffer. In this way, even if the time interval exists between reception and playback, the currently played video frame and subsequent video frames can be read from the record buffer and written onto an HDD.
