Abstract
Abstract Methods and apparatus for encoding and decoding an audio and/or video signal, and a record carrier for use with such apparatus. One or more audio and/or full motion video signals, e.g., a video signal (and possibly computer data), are recorded on an interactive compact disc. The video signal prior to being recorded is encoded into code blocks of variable lengths, each corresponding to a picture or picture pair. A decoder delay time parameter associated with one or more of the code blocks, which parameter represents a length of time (i.e., a delay time) with which the corresponding picture of a code block is to be displayed after that code block has been received by a decoding apparatus is determined and included in the video signal prior to being recorded.
