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.

摘要： Methods and systems for providing satellite television service to a premises may comprise receiving satellite television signals utilizing a satellite dish, converting received satellite signals to internet protocol (IP) signals, and wirelessly communicating the IP signals into a premises to which the satellite dish corresponds. The IP signals may, for example, conform to a multimedia over cable alliance (MoCA) standard or a IEEE 802.11x standard. The wirelessly communicating may comprise magnetic coupling. The received satellite signals may, for example, be converted to IP signals utilizing an IP low-noise block downconverter (IP-LNB) which may comprise full-band capture receivers. The wireless communication of the IP signals may, for example, be within a wireless network of the dwelling or may be independent of a wireless network of the dwelling. The wirelessly communicated IP signals may be beam-formed and may be communicated wirelessly over one or more industrial, scientific, and medical (ISM) bands.

摘要： A network device (e.g., a cable modem) may support a normal mode of operation and a sleep mode of operation. While in the normal mode, a PHY of the network device may process a received signal to recover MPEG-TS packets, and convey the MPEG-TS packets to other components of the network device for further processing. While in the sleep mode, the PHY may process received MPEG-TS packets having a particular packet identifier and drop received MPEG-TS packets not having the particular packet identifier. The PHY may control transitions between the normal mode and the sleep mode in response to received signals having particular physical layer characteristics. The PHY may demodulate a received signal to recover an MPEG-TS packet; descramble portions of the MPEG-TS packet; inspect portions of the MPEG-TS packet; and control a mode of operation of the network device based on the contents of the MPEG transport stream.
