Method and apparatus for providing an enhanced Wi-Fi display session in a Wi-Fi display network, and system thereof

An apparatus of multicasting multimedia streaming content to a plurality of WFD sink devices in a Wireless Fidelity Display (WFD) network, comprising:

• a control unit;
• and
• a Wi-Fi module communicatively coupled to the control unit,
• wherein the control unit is configured for:
• setting up a WFD connection with a plurality of WFD sink devices;
• broadcasting a WFD capability request frame to the plurality of WFD sink devices;
• receiving via the Wi-Fi module, a WFD capability response frame comprising capability information and an audio and video intent value from each of the plurality of WFD sink devices, wherein the capability information includes information indicating whether the WFD sink device is able to render audio or video data;
• establishing a WFD session with multiple WFD sink devices in the plurality of WFD sink devices based on the capability information and the audio and video intent value;
• and
• streaming multimedia content to the multiple WFD sink devices during the WFD session,
• wherein the control unit is further configured for:
• selecting at least one renderer device from the plurality of WFD sink devices based on the audio and video intent value in the WFD capability response frames;
• and
• broadcasting a WFD renderer announcement frame indicating selection of the at least one renderer device to the plurality of WFD sink devices.

A Wireless Fidelity Display (WFD) system, comprising:

• a WFD source device;
• and
• a plurality of WFD sink devices,
• wherein the WFD source device is configured to set up a WFD connection for wirelessly communicating with a plurality of WFD sink devices in a WFD network, broadcast a WFD capability request frame to the plurality of WFD sink devices over the WFD connection, receive a WFD capability response frame from each of the plurality of WFD sink devices in response to the WFD capability request frame, wherein each WFD capability response frame comprises capability information and an audio and video intent value of a respective WFD sink device of the plurality of WFD sink devices, wherein the capability information includes information indicating whether the WFD source device is able to render audio or video data, establish a WFD session with multiple WFD sink devices among the plurality of WFD sink devices based on the capability information and the audio and video intent value from respective WFD capability response frames from the multiple WFD sink device, and stream multimedia content to the multiple WFD sink devices during the WFD session, and
• wherein the WFD source device is further configured to select at least one renderer device from the plurality of WFD sink devices based on the audio and video intent value in the WFD capability response frames, and broadcast a WFD renderer announcement frame indicating selection of the at least one renderer device to the plurality of WFD sink devices.
