Design considerations for interactive audio streaming on wireless handheld controllers

Interactive audio streaming over wireless network is usually carried out over high bandwidth wireless channels and is implemented using computationally well-resourced devices. This paper describes two basic design configurations for interactive audio streaming on a handheld controller that communicates with a host PC over a low data rate wireless network and operates under low power and processing capability conditions. The first design considers direct streaming of audio data over the wireless channel and the second considers audio data streaming from a local external memory within the remote device. We discuss issues related to audio playback quality and power consumption for each of this design configuration.
