Patent

CA 2182057

Apparatus and method of recording coded picture data on a recording medium which operates to receive the picture data (e.g., a video data), code the picture data using intra-picture coding and/or predictive coding to provide one I-picture and one succeeding P-picture, generate positional information representing the positions of the I-picture and the P-picture relative to the I-picture, and record the I-picture, the P- picture, and the positional information on the recording medium. The coded picture data is reproduced from the recording medium in a special reproduction mode by selectively reading the data using the positional information.
