US 2012/0059496 A1 · Method and device for transmitting audio data over universal serial bus by a wireless data terminal

Abstract

A method and a device for transmitting audio data over Universal Serial Bus (USB) audio data by a wireless data terminal are disclosed. The method includes that: a USB audio data transmission channel between a wireless data terminal and terminal equipment is set as USB sound card equipment by adopting the standard USB AUDIO CLASS defined by the USB specification, to transmit audio data; the device includes a wireless data terminal, USB sound card equipment, and terminal equipment. The USB sound card equipment only transmits audio data, and does not process audio data; a USB audio equipment driver of the terminal equipment accesses a USB endpoint of the terminal equipment in a manner of accessing a sound card interface. By adopting the method and the device of the present invention, the USB audio data transmission channel is specifically optimized, and the powerful audio data processing capability of terminal equipment is fully utilized to enhance the effectiveness of Voice Over USB (VOUSB) in the practical application.
