发明名称 Method and system for providing faster channel switching in a digital broadcast system
摘要 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.
