Abstract

The invention discloses a voice data transmission method based on a USBHID protocol. The method comprises the following steps: defining a first interface for transmitting a standard instruction and asecond interface used for transmitting voice data and a passive instruction; arranging at least one interrupt pipeline in the IN direction below the second interface; and in response to an uploading instruction / passive instruction of the voice data, uploading the voice data to the equipment end through the interruption pipeline to complete transmission of the voice data. The invention also discloses a voice data transmission system based on the USBHID protocol and a remote controller, and according to the method and the system disclosed by the invention, the voice data and the control information can be efficiently and bidirectionally transmitted to the remote control end and the equipment end through a simple and convenient protocol.

Description

technical field [0001] The invention relates to the technical field of remote control, in particular to a voice data transmission method, system and remote control based on the USBHID protocol. Background technique [0002] With the popularization of scientific and technological products, remote control products are widely used in the control of televisions, air conditioners, computers, audio and other household appliances. The remote control mainly relies on an integrated circuit (also called a chip) to send instructions, and encodes related information such as buttons in the form of corresponding codes, and the codes of each button are different. At the controlled end, decode according to the received relevant information, and then make corresponding operations. According to the product form of the remote control, the market can be divided into infrared remote control, Bluetooth remote control, 2.4G remote control, and its transmission protocols include IR infrared, 2.G a...
