  • Patent number: 11139902
    Abstract: An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

  • Patent number: 11036270
    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.

  • Patent number: 10848340
    Abstract: Methods and systems are provided for power management in communication devices, particularly based on cable connectivity. In a communication device that includes a communication port, including a first connector and a signal path communicatively coupled to the connector, measurements associated with the signal path may be obtained. Based on the obtained measurements, it may be determined whether an external cable is mated to the connector, and the communication device may be transition to a sleep mode when it is determined that the external cable is not mated to the connector. Determining whether the external cable is mated may be based on detecting presence or absence of a signal on the signal path, based on evaluating signal characteristics of a signal present on the signal path, measuring of voltage or current at the communication port, and/or energy measurements associated with one or more particular frequencies.

  • Patent number: 10659103
    Abstract: Systems and methods are provided for synchronizing multiple channels in an access network, where the multiple channels are neighboring channels such that a guard band between them or use of a diplexer to prevent inter-channel interference is not required. Synchronization is achieved by defining channel MAP (media access plan) cycle structures such that all channels work in the same direction (upstream US or downstream DS) at any given time. Moreover, the network controller of channel may send out a beacon to allow new nodes to join. A long MAP cycle (402) may be followed by three consecutive regular MAP cycles (404, 406), and (408). These MAP cycles are repeated between beacon transmissions. Synchronization allows multiple channels to be configured contiguous (without a guard band between neighbouring channels) and without utilizing diplexers. A plurality of customer premises equipment may operate on each of the communications channels.
