Abstract
A decoded video signal which was encoded in accordance with a standard, such as MPEG-2, is encoded "on the fly" using a lossless linear predicted coding technique and stored in a compressed form in a RAM. A separate encoding technique is provided for B pictures and for I or P pictures. The compressed B pictures are decompressed for display. The compressed I or P pictures are decompressed for display or for use in decoding other P or B pictures.
