Abstract

The embodiment of the invention discloses an ARC (Audio Return Channel) setting method and equipment. The method comprises the steps of transmitting a request of obtaining a logical address to the equipment when detecting that the equipment accesses to an HDMI (High-definition Multimedia Interface), judging whether a type of the equipment is a power amplifier according to the logical address returned by the equipment, generating an instruction of setting an ARC if the type of the equipment is the power amplifier and that the power amplifier is connected with an ARC pin of the HDMI is determined, and transmitting the instruction of setting the ARC to the power amplifier to indicate the power amplifier to set the ARC of the power amplifier as the current audio channel according to the instruction. The current audio channel is set by an adjusting knob on the power amplifier, the power amplifier can only set the channel corresponding to the current rotating position as the current audio channel each time, and the power amplifier can operate on the ARC by many attempts possibly in the prior art. Therefore, the method and the equipment improve control efficiency of an ARC function compared with the manner that the adjusting knob on the power amplifier sets the ARC of the power amplifier.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an Audio Return Channel (Audio Return Channel, ARC) channel setting method and device. Background technique [0002] The ARC function is a function in the High-Definition Multimedia Interface (HDMI) 1.4 port specification, which can improve audio quality, and its basic protocol is the Consumer Electronics Control (CEC) protocol. With the development of multimedia technology, many multimedia devices, such as televisions and power amplifiers, support the ARC function. [0003] Take the TV as an example, in the scene where the power amplifier is connected to the TV, and the TV sends the audio signal back to the power amplifier through the ARC function, the ARC port of the power amplifier is connected to the HDMI port with the ARC function on the TV. Based on this hardware connection method, HDMI1, HDMI2, HDMI3, HDMI4, Audio Video (Audio Video, AV)1, AV2, AV3, AV4 and ot...
