摘要：

In this paper, we propose a system which can easily control the existing serially connected multi-channel speakers using a USB(Universal Serial Bus) interface. The host computer chooses a sound source and sends audio data in a real-time fashion using isochronous transmission, which is one of four transmission methods provided by the USB interface. In addition, a channel is assigned to use the bulk transmission method. Transmitted data from the USB host are compressed and packetized before being sent serially to the speakers. Each speaker detects corresponding digital data and regenerates audio signals through DAC(Digital-to-Analog Converter). A user can easily select a sound source file and a channel by the use of a GUI environment in the host computer.
