SPEEDING UP CHANNEL CHANGE

摘要

A method and apparatus is described to reduce delay when changing channels in a television environment. The method may comprise receiving a plurality of television channels from a remote content provider wherein each channel includes channel information required to display the channel. At least one channel of the plurality of channels may be identified as a stored channel and channel information of the at least one stored channel may be stored in storage (e.g. in a circular buffer). Thereafter, upon selection of the stored channel, the stored channel information is accessed for display. In an example embodiment, the storage may be updated to maintain a most recently received I-frame and subsequent MPEG signals of the stored channel. Accordingly, when changing channels it may not be necessary to wait for the next I-frame to display a newly selected channel.
