Abstract:
In response to a video and audio bandwidth allocation request command signal and an audio bandwidth allocation request command signal from a source device, a coordinator device allocates a first reservation period for transmitting AV stream data from the source device to a sink device and a second reservation period for transmitting audio stream data from the source device to a sink device within a predetermined frame period, and transmits a beacon signal including information on allocation of the first reservation period and the second reservation period.
