发明名称 System and method for low-delay channel hopping
摘要 A system and method are provided for low-delay channel changes in a multicast/broadcast of compressed video. The method comprises: receiving a multicast/broadcast with a plurality of compressed video channels; buffering information from a plurality of channels; selecting a channel; and, decoding the selected channel in response to the buffered information. In some aspects, the method pre-identifies access points in the buffered information for each channel, prior to selecting the channel. Then, decoding the selected channel in response to the buffered information includes: accessing the buffered information at the pre-identified access point; and, decoding the selected channel, beginning at the access point. Alternately, access points are not pre-identified. Then, decoding the selected channel in response to the buffered information includes: discovering an access point in the information buffered for the selected channel subsequent to selecting the channel; and, decoding the selected channel, beginning at the discovered access point.
