WIRELESS QUIET ENROLMENT

摘要

In a wireless media network a source device provides entertainment content to a sink device over a radio frequency (RF) wireless channel. The source device can go into a receive only quiet enrolment mode until activated by a sink device transmitting enrolment trigger packets or having a signal strength above a certain threshold, thereby improving coexistence with other wireless devices. The source device changes from the quiet enrolment mode to an active enrolment mode when activated by the sink device.

主权项

1. A wireless media network, comprising:
a source device for wirelessly transmitting media data packets; and at least one sink device for wirelessly receiving the media data from the source device; the source device comprises an active enrolment mode, a quiet enrolment mode and a data mode, wherein the source device transmits enrolment packets and listens for response packets from the at least one sink device when in the active enrolment mode, if valid response packets for active enrolment are received from the at least one sink device then the source device goes into the data mode with the at least one sink device and transmits the media data packets thereto, and the source device listens for a signal from the at least one sink device when in the quiet enrolment mode, when the signal is received then the source device goes into the active enrolment mode, and if the valid response packets for active enrolment are not received from the at least one sink device then the source device goes back into the quiet enrolment mode after an enrolment timeout.
