摘要： An apparatus and method for providing an enhanced Wireless Fidelity (Wi-Fi) display (WFD) session in a WFD network. 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.

摘要： A system that enhances Wi-Fi display and enables a non WFD device to establish a session with a WFD source in an existing WFD session and to function as an offline WFD source without terminating an existing WFD session. The system enables an offline WFD source to stream multimedia content and control packets to sinks via the WFD source and control packets from the sinks to the offline WFD source. The system eliminates a need to reestablish a new session and improves workflow and a user experience.
