Audio/video streaming in a topology of devices with native WiGig sink

摘要

A method and system may include a source station to provide wireless multicast transmission to a plurality of destination stations according to a protocol adaptation layer multicast management protocol. The topology includes audio/video sources and sinks and intervening branch devices. Messages between sources and sink devices may be used for resource management such as device discovery and certification. If certification is shown, the disclosed transmission performs AV streaming directly to the least one sink device without the need for a displayport (DP) interface or a high definition multimedia interface (HDMI) or additional bridge devices/dongles that convert WiGig to some other interface supported by the monitor.

1. A method comprising:
establishment of streaming with a device in a topology of devices, including devices that source and sink video and/or audio data, if a field within a message contains a unique identifier certifying the device as capable of directly sinking a stream from a source; wherein the message is a capability response packet generated by the device; wherein the capability response packet is extended to include video endpoints, audio endpoints, and WiGig signature fields; wherein the device is at least one of audio device, video device, audio video device, a device with multiple audio video endpoints, a device with unequal number of audio and video endpoints, or a device with one or more downstream high definition multimedia interface (HDMI) or displayport (DP) connectors.
