Claim Text:
1. An adaptive decoding multi-layer video system comprising: a base layer decoder; one or more enhancement layer decoders; a reference processing unit connected with the base layer decoder and the one or more enhancement layer decoders, the reference processing unit being configured to store reference frames; and a decoding adaptor connected with the base layer decoder, the reference processing unit and the one or more enhancement layer decoders, the decoding adaptor receiving feedback from the base layer decoder, the reference processing unit and the one or more enhancement layer decoders, the decoding adaptor controlling operation of the base layer decoder, the reference processing unit and the one or more enhancement layer decoders, the decoding adaptor being configured to: read a frame under consideration; set a decoding mode for the frame under consideration based on a decoding time of previously decoded frame; calculate a decoding time for the frame under consideration; determine whether the decoding time is higher or lower than a first threshold; if the decoding time is higher than the first threshold: determine whether the decoding time is higher or lower than a second threshold, the second threshold being lower than the first threshold; and decode the frame under consideration according to the set decoding mode; update the decoding time of the previously decoded frame after each decoding, wherein the decoding time comprises an average decoding time or a nonaverage decoding time; and repeatedly read, set, and decode if further frame is available.
