Abstract: 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.

Abstract: 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.
