Abstract:
1. A method for switching between channels of encoded media data comprising: receiving encoded media data for a plurality of channels, wherein encoded media data for each of the plurality of channels comprises a plurality of frames of data including reference frames and dependent frames, wherein each dependent frame refers to at least one reference frame; concurrently decoding frames associated with a first channel from the plurality of channels to generate a decoded signal for the first channel, and storing a latest-received reference frame associated with a second channel from the plurality of channels; in response to receiving a control signal for switching from the first channel to the second channel, decoding at least one dependent frame associated with the second channel, by utilizing the latest-received reference frame corresponding to the at least one reference frame associated with the second channel, to generate a decoded signal for the second channel.
