Abstract:
An apparatus and method for providing an enhanced Wireless Fidelity (Wi-Fi) display (WFD) session in a WFD network, and system thereof. Once a WFD connection is setup, a WFD source device broadcasts a WFD capability request frame to multiple WFD sink devices over the WFD connection. In response, each of the WFD sink devices sends a WFD capability response frame to the WFD source device. The WFD capability response frame contains capability information and audio and video intent value associated with the respective WFD sink devices. The WFD source device consolidates a sink property table using the capability information and the audio and video intent value associated with respective WFD sink devices. The WFD source device establishes a WFD session with the multiple WFD sink devices. The WFD source device streams multimedia content to the WFD sink devices in a multicast manner.
