A low power partial functionality communication link that includes a first mode of operation for transmitting a first high throughput data stream including a plurality of data types over wires, and a second low power partial functionality mode of operation for transmitting, over a subset of the wires used for transmitting the first data stream, a second low throughput bidirectional data stream that may include less data types than the first data stream.

Low power partial functionality communication link

Methods and devices for a low power partial functionality communication link having an Ethernet mode of operation and a low power partial functionality mode of operation. The communication link may process only frames containing predefined data types while in the low power partial functionality mode.

Ethernet low power partial functionality communication link

A daisy chain device including a first active mode of operation and a second low power mode of operation. In the first active mode of operation the daisy chain device supplies or receives multimedia data containing at least two types of data. In the second low power mode of operation the daisy chain device relays only predefined data types and consumes less power. Wherein the daisy chain connection includes wires and the transmissions in the different modes of operation are over the same wires.

Methods and devices for daisy chain CE device power save modes

Power saving techniques for a device including an active mode of operation for transmitting a first data stream of at least two data types over wires, and a low power partial functionality mode of operation for transmitting a second data stream over a subset of the wires used for transmitting the first data stream. The power saving techniques may utilize different modulation schemes, different throughputs, different symbol rates, or other techniques.

Power saving techniques for a partial functionality communication link

Communication link including a cable containing four pairs of wires, three transmitters to transmit uncompressed video data and audio data over three of the pairs of wires to three receivers, and two transceivers to form a bidirectional multi data type communication link over the fourth pair of wires. An active mode of operation for transmitting the uncompressed video data and the audio data over the three pairs of wires, and for transmitting bidirectional data over the fourth pair of wires. And a first low power partial functionality mode of operation for transmitting bidirectional system controls.

High definition and low power partial functionality communication link

Methods for operating a multi data type communication link transceiver, including: testing the type of the link partner transceiver. If the link partner transceiver is not a multi data type communication link transceiver, operating the multi data type communication link according to the detected type of the link partner transceiver. If the link partner transceiver is a multi data type communication link transceiver, further including the steps of negotiating the functionality required from the multi data type communication link with the link partner, and switching to an appropriate mode of operation.
