The present invention relates to a communication system, a transmitter, a receiver, a communication method, a program, and a communication cable for providing high-speed bidirectional communication while maintaining compatibility. When an HDMI (R) source 71 performs bidirectional IP communication with an HDMI (R) sink 72 using a CEC line 84 and a signal line 141, a switching control unit 121 controls a switch 133 so that, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a converting unit 131 and, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a receiver 82. When bidirectional communication is performed using only the CEC line 84, the switching control unit 121 controls the switch 133 so that the CEC signal output from the HDMI (R) source 71 or the receiver 82 is selected. The present invention is applicable to, for example, HDMI (R).

A differential includes first and second current mirror circuits that provide the gates of slave transistors with gate voltages of master transistors via a voltage follower where a slew rate at a rise time is equal to a slew rate at a fall time. Thus, when the master current is increased or decreased, an incremental change in slave current and a decremental change in slave current are symmetrical with each other. The use of such current mirrors in a differential manner leads to no generation of common mode noise even in these changes.

A video signal and an audio signal are TMDS transmitted from a source device to a sink device. Through a reserved line and a HPD line provided separately from a TMDS transmission line, an Ethernet™ signal is bidirectionally transmitted, and also, a SPDIF signal is transmitted from the sink device to the source device. The Ethernet™ signal bidirectionally transmitted between Ethernet™ transmitter/receiver circuits is differentially transmitted by an amplifier and is received by the amplifier. The SPDIF signal from a SPDIF transmitter circuit is common-mode transmitted from an adder and is received by the adder to be supplied to the SPDIF receiver circuit.

The present invention provides a data transfer system including a data transmitter and a data receiver. The data transmitter converts a plurality of bits of transmission parallel data into serial data and generates a multi-level logic signal representing a plurality of bits of information in one symbol, the information being obtained by combining the serial data with a word clock as one-bit information. The word clock indicates a word delimiter in the serial data. The data receiver receives the transmitted multi-level logic signal, extracts the serial data and the word clock from the signal, and reproduces the parallel data based on the extracted word clock. In the data transfer system, a multi-bit digital signal can be transmitted as one signal including a word clock. Thus, components and mounting space to be allocated to transfer can be reduced.

This device has a first circuit including a first field effect transistor and a second circuit coupled to a source of the first electric field transistor. The second circuit applies a first source bias voltage, which does not reversely bias between a source and a body of the first field effect transistor, to the first field effect transistor during the operation mode of the first circuit, and applies a second source bias voltage, which reversely biases between the source and the body of the first field effect transistor, to the first field effect transistor during the standby mode of the first circuit. During the standby mode of the first circuit, the leakage current that flows through the first FET is reduced by means of the reverse bias effect produced by applying the second source bias voltage to the source of the first FET.
