Abstract
An apparatus and method for session management and control procedures for supporting multiple groups of sink devices in a peer-to-peer wireless display system are described. One implementation may include an apparatus configured to transmit multimedia content to a plurality of sink devices. The apparatus may comprise a processor configured to connect to each of the sink devices with a Wi-Fi peer-to-peer connection. The processor may further be configured to receive capability information from each of the sink devices. The processor may further be configured to generate a control message including a group session ID and a transport port number. The processor may further be configured to determine a set of streaming parameters for the sink devices. The processor may further be configured to transmit, using the transport port number and according to the set of streaming parameters, the particular multimedia content to each of the Wi-Fi peer-to-peer connected sink devices.
