Patent ID: 8155192

Claim:
A method for decoding a plurality of substreams of a bitstream representing an interlaced sequence of video data, wherein the single substreams are associated with either a base layer or an enhancement layer, the method comprising the steps of extracting from the bitstream those substreams that are associated with the base layer; performing spatio-temporal synthesis on said substreams, wherein a progressive mode video sequence is generated; selecting or determining a decode quality being either a basic or an enhanced decode quality, wherein control signals from a transmitter or content provider, technical capabilities at the receiver side and/or user preferences are evaluated; upon selection of an enhanced decode quality, performing spatial synthesis on said progressive mode video sequence and a substream associated with the enhancement layer, wherein the spatial synthesis generates an enhanced progressive mode video sequence; performing an inverse motion-compensated temporal filtering on said enhanced progressive mode video sequence and one or more of the substreams being associated with the enhancement layer; and performing inverse splitting on the output of said inverse motion-compensated temporal filtering and said enhanced progressive mode video sequence, wherein an interlaced video sequence of enhanced or full spatio-temporal resolution is generated.
