Abstract
Official abstract text for this publication.
Methods, apparatuses, and systems are presented for switching between channels of encoded media data involving receiving encoded media data including reference frames and dependent frames for a plurality of channels, wherein each dependent frame refers to at least one reference frame. Frames associated with a first channel from the plurality of channels are decoded to generate a decoded signal for the first channel. While decoding frames associated with the first channel, data corresponding to at least one reference frame associated with a second channel from the plurality of channels are stored. In response to a control signal for switching from the first to the second channel, at least one dependent frame associated with the second channel is decoded by utilizing the stored data corresponding to the at least one reference frame associated with the second channel, to generate a decoded signal for the second channel.
First claim
Opening claim text (preview).
What is claimed is: 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; decoding frames associated with a first channel from the plurality of channels to generate a decoded sign…
