    摘要： A wireless communication system is enhanced to allow for low-latency channel surfing and to enable a user to quickly see the content carried over a selected channel while searching channels for desired content. The techniques for reducing the channel change latency may be implemented in a transmitter, receiver, or in a combination of transmitter and receiver. The wireless communication system is optionally a DVB-H communication system. The transmitter may generate and transmit one or more auxiliary channels, where each auxiliary channel contains reduced resolution content corresponding to one or more channels. The receiver may process the one or more auxiliary channels to present the reduced resolution content while processing the full resolution channel for display. The receiver caches portions of content from one or more non-selected channels and presents the cached content when the channel is selected while concurrently searching and processing the full resolution channel content.
