  • Decoding frames
    Patent number: 10142644
    Abstract: A system for decoding a data stream, comprising: a first decoder configured to decode the data stream at a first rate so as to generate a first stream of frames for playback and arranged to continue generating the first stream despite encountering an error in a particular frame; a second decoder operable to decode the data stream at a second rate so as to generate a second stream of frames; and a controller configured to: detect the error and cause the second decoder to decode the data stream from the particular frame in dependence on error correction data, the second rate being faster than the first rate such that the second stream catches up with the first stream; determine when the second decoder catches up with the first decoder; and cause the second decoder to operate at the first rate so as to generate the second stream for playback.
    Type: Grant
