Abstract
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.

A wireless media network, comprising:
- a source device including a non-transitory machine-readable medium, the medium including instructions, the instructions, when loaded and executed by a processor, configure the source device to wirelessly transmit media data packets;
- and
- a sink device including a non-transitory machine-readable medium, the medium including instructions, the instructions, when loaded and executed by a processor, configure the sink device to wirelessly receive the media data from the source device;
- wherein the source device further includes instructions to configure the source device to:
- operate in an active enrolment mode, a quiet enrolment mode and a data mode;
- when in the active enrolment mode:
- transmit enrolment packets and listen for response packets from the sink device;
- and
- if valid response packets for active enrolment are received from the sink device, go into the data mode with the sink device and transmit the media data packets thereto;
- if the valid response packets for active enrolment are not received from the at least one sink device after an enrolment timeout, enter the quiet enrolment mode;
- when in the quiet enrolment mode:
- listen for a signal from the sink device, the signal comprising an average RSSI having a level greater than a quiet enrolment trigger threshold;
- and
- when the signal is received, go into the active enrolment mode.
