Abstract

The invention discloses a voice data transmission method based on the USBHID protocol, comprising the following steps: defining a first interface for transmitting standard commands; and a second interface for transmitting voice data and passive commands; setting at least An interrupt pipe with direction IN; in response to the voice data upload command / passive command, upload to the device through the interrupt pipe to complete the transmission of voice data. The invention also discloses a voice data transmission system and a remote controller based on the USBHID protocol. According to the method and system disclosed in the invention, the voice data and control information can be transmitted bidirectionally for the remote control terminal and the device terminal efficiently 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...
