Abstract: Systems and methods for providing power to a home entertainment integrated circuit chip are disclosed. The home entertainment integrated circuit chip can operate in at least two power control modes: “power on” mode and “standby” mode. In power on mode, power is supplied to IC core module from a main power supply. The power supplied to the IC core module is isolated from power supplied to a standby island. Accordingly, during the second mode power is applied only to the standby power island through a regulator internal to the integrated circuit chip. The regulator is coupled to an external peripheral input/output (I/O) power supply that is independent of the main power supply.

Abstract: A method, system and computer program for decompressing video data, storing the compressed video data in such a way that random access is possible and the data can be mapped efficiently into existing memory systems and interface protocols. The compression is accomplished via lossless compression using an algorithm optimized for video data. Due to the compressed format, data transmission consumes less bandwidth than using uncompressed data and prevents degradation in the decoded video.

Aspects of the disclosed method and apparatus make use of the RVU messaging protocol, which include a Discovery phase and a Description phase. In one embodiment, a stand-alone testing device includes functionality that can test for the existence of RVU capability in a network connected device; in another embodiment, a cable/data network interface device may be modified to include such functionality. One detection method exams messages transmitted by a device during a Discovery phase for unique indicia of RVU compliance by the device. Another detection method reads a data structure from a device during a Description phase and looks for unique indicia of RVU compliance by the device. An installation method provides a process for quickly and definitively detecting an RVU compliant device.

Abstract: A cascaded diplexer to create a cascaded diplexer leg with selectable passbands has a cascaded diplexer circuit. The diplexer circuit has a plurality of first bandpass filters, each having a passband. The diplexer circuit has a second bandpass filter having a passband and two terminals, coupled in series with a first bandpass filter. First and second switches are coupled in series with the second bandpass filter and the first bandpass filter, the first and second switches being configured to selectably switch the second bandpass filter into the circuit. The passband of the second bandpass filter is chosen to limit the passband of the first bandpass filters, such that when the second bandpass filter is switched into the circuit, the passband of the diplexer leg is reduced. The passband of the second bandpass filter may be a subset of, or overlaps with, the passband of the first bandpass filter.

Abstract: A method, system and circuit for providing for part or all of a transmitter, when it is in mute mode (not actively transmitting), to be turned off, removed, decoupled or modified in general in order to reduce the total noise submitted by the transmitter to the wired network into network controller. In parallel, an auxiliary circuit or impedance is added or coupled to the transmitter in order to mitigate the total return loss change of the transmitter. When in active transmitter mode, this auxiliary circuit or impedance will be removed or decoupled from the transmitter and transmitter will transmit in normal mode.

Abstract: Systems and methods for removing interference from a received signal. A model of a leakage path from a transmit section to a receive section is used to assist in designing a set of iterative filters to remove interference. Modeling the leakage path allows generation of the first approximation of the transfer function of the leakage path traversed by the signals coupled from the transmit section to the receive section. The first approximation narrows down the universe of possible distortions that might occur due to the transfer function of the leakage path. Narrowing down the universe of possible solutions makes the complexity of the interference control section more manageable. An iterative LMS function is used to further refine the coefficients of the adaptive filters.

Abstract: A non-transitory computer readable media having instructions stored thereon that, when executed by a processor, cause the processor to optimize a network that is formed from a plurality of nodes. The instructions cause the processor to execute an order that the plurality of nodes perform a probing operation. The order is typically round robin. The processor receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the processor changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.
