摘要:
One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.

A first network device may discover one or more values of one or more parameters corresponding to a plurality of links and/or devices of the network. The first network device may compare the discovered one or more values of the one or more parameters to an expected one or more values of the one or more parameters. The first network device may determine whether to transmit data onto a network path between the first device and one of the plurality of devices based on a result of the comparison, wherein at least one of the plurality of links and/or devices are not part of the network path. The first network device may be operable to utilize the discovered parameter values to generate a security key which may be utilized to encrypt and/or scramble content prior to transmitting the content onto the network.

A first device of a multimedia over coax alliance (MoCA) network may grant a second device of the MoCA network permission to enter a power-saving state. While the second device is in the power-saving mode, the first device may grant bandwidth to the second device during one or more predetermined timeslots. The bandwidth may be granted without a corresponding reservation request from the second device. While the second device is in the power-saving state, it may track time utilizing a clock that is synchronized to the system time of the MoCA network, and transmit during one or more of the predetermined timeslots without first transmitting a corresponding reservation request. The second device may utilize a first modulation profile when not operating in the power-saving state, and utilize a second modulation profile when operating in the power-saving state.

Methods and systems for improved cross polarization rejection and tolerating of coupling between satellite signals may comprise receiving radio frequency (RF) signals on a chip, where the RF signals comprising a desired signal and at least one crosstalk signal. The received RF signals may be down-converted to baseband frequencies, and the down-converted signals are converted to digital signals. Crosstalk may be determined by estimating complex coupling coefficients between the received RF signals utilizing a de-correlation algorithm across a frequency bandwidth comprising the desired and crosstalk signals. The down-converted signals may be low-pass filtered and summed with an output signal from a cancellation filter. The complex coupling coefficients may be determined utilizing the de-correlation algorithm on the summed signals, and may be used to configure the cancellation filter. Crosstalk may be canceled in a receiver path from a cancellation filter receiving low-pass filtered down-converted signals from another path.
摘要:
Methods and apparatus for power control in a communications device are described. Bonding of channels in a modem may be dynamically adjusted responsive to user activity or demand for bandwidth. Bonded channel configurations may be adjusted to single channel configurations for low power operation. Modem configuration may be dynamically adjusted so as to maintain only required synchronization and system information to facilitate rapid data transfer resumption upon demand.

A integrated broadband transceiver is operable to communicate signals at a power level that is below a spurious emissions mask and to spread said communicated signals over a designated frequency spectrum band. The integrated broadband transceiver is operable to detect usable channels within the designated frequency spectrum band and wirelessly communicate content with one or more other integrated broadband transceiver enabled devices over the one or more of said detected channels. The one or more other integrated broadband transceiver enabled devices are also operable to communicate signals at the power level that is below the spurious emissions mask and to spread said communicated signals over said entire designated frequency spectrum band. The integrated broadband transceiver may be paired with the other integrated broadband transceiver enabled devices utilizing broadband near-field communication (BNC) protocols. The integrated broadband transceiver may be configured with security levels during the pairing based on corresponding.

摘要:
Methods and systems for cross-protocol time synchronization may comprise, for example in a premises-based network, receiving a signal that conforms to a first communications protocol (e.g., a general-purpose communications protocol), extracting a global time of day (GTOD) clock from the received signal; and synchronizing communication on the premises-based network in accordance with a second communication protocol, based at least in part on the extracted GTOD clock. The first communications protocol may comprise data over cable service interface specification (DOCSIS) or any protocol that provides a GTOD. The second communication protocol may comprise a multimedia over cable alliance (MoCA) standard, an IEEE 802.11x standard, or any non-public wireless network protocol. The GTOD clock may comprise a GPS clock, a GLONASS clock, and/or a Galileo clock. One or more of the networked devices may comprise a network controller, where the network controller comprises wireless network and wired network capability.

This sit-up support device is designed to hold a person's feet when they are performing bent knee sit-ups. Primarily, it consists of a base plate that is rendered stationary to the floor by a clamp that fastens to a door. The device also includes quick-release straps on the base plate, for comfortably holding the user's feet, and a threaded shaft and sleeve are provided in conjunction with the clamp, to force the base plate hard down to the floor.
