摘要： A cable modem (CM) device captures signals over a wide spectrum including one or more cable frequency bands and sub-bands, and extracts one or more cable channels from the captured signals. The CM device is operable to analyze the extracted one or more cable channels and assigns a portion of the extracted one or more cable channels for upstream and/or downstream communication based on the analysis. The CM device may recapture one or more previously unused cable channels to be utilized for the upstream and/or downstream communication based on the analysis. The CM device may determine noise, interference and/or blocker information corresponding to the extracted one or more cable channels based on the analysis. Based on the determined noise, interference and/or blocker information, the cable modem termination system (CMTS) may assign or block usage of one or more cable channels for the upstream and/or downstream communication.

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.

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.

摘要： A network device may be operable to receive an indication from a cable modem termination system (CMTS) that media access control (MAC) management messages will be transmitted by the CMTS at fixed intervals. Subsequent to receiving the indication, the network device may be operable to power down one or more components of the network device and set a sleep timer to a value equal to an integer multiple of the fixed interval minus a transition period. The network device may power up the one or more components of the network device upon expiration of the sleep timer. The network device may power up the one or more components of the network device upon an amount of traffic in a buffer of the network device reaching a threshold.

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： A CMTS may receive a request that a network device be permitted to enter a power-saving mode of operation. In response, the CMTS may enter a power-saving mode of operation wherein MAC management messages, transmission opportunities for the sleeping network device, and/or contention periods on one or more channels occur at independently determinable intervals. The CMTS may then transmit a message granting the network device permission to enter the power-saving mode of operation. The CMTS may start a sleep timer upon transmitting the MAC management message and may deregister the network device if no communication is received from the network device prior to expiration of the sleep timer. The CMTs may buffer traffic destined for the network device in a buffer of the CMTS while the network device is in the power-saving mode of operation, and may wake the network device upon the amount of buffered traffic reaching a threshold.
