1. A transceiver configured to operate according to different modes of operation:
- the transceiver is configured to operate according to a first mode of operation in order to transmit in a first direction bidirectional communication comprising data of at least two types, over a certain wire comprised in a cable, wherein at least one of the data types is uncompressed high definition digital video and another data type is bidirectional data;
the transceiver is further configured to receive in a second direction, while operating in the first mode of operation, data of the bidirectional data type;
the transceiver is further configured to operate according to a first low power partial functionality mode of operation in order to transmit and receive bidirectional communication comprising bidirectional data over the certain wire; and
the transceiver is further configured to transmit at least one data type in the first mode of operation that is not transmitted in the first low power partial functionality mode of operation;
wherein the ratio between power consumption of the transceiver in the first mode of operation and the power consumption of the transceiver in the first low power partial functionality mode of operation is at least 3;

Abstract
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.

16. A communication link comprising transceivers coupled by a cable, the transmitters configured to operate according to different modes of operation:
-
the transceivers are configured to operate according to a first mode of operation for transmitting data of at least two types, over a certain wire comprised in the cable, wherein at least one of the data types is uncompressed high definition digital video transmitted from a source device to a sink device and another data type is bidirectional data transmitted in a first direction between the source device and the sink device; the transceivers are further configured to transmit the bidirectional data in a second direction over the certain wire, while operating in the first mode of operation; the transceivers are further configured to operate according to a first low power partial functionality mode of operation for transmitting a second bidirectional data between the source device and the sink device over the certain wire; and the transceivers are further configured to transmit in the first bidirectional data at least one data type that is not transmitted in the second bidirectional data; wherein ratio between power consumption of the transceivers in the first mode of operation and power consumption of the transceivers in the first low power partial functionality mode of operation is at least 3;
