Abstract
Embodiments related to storing and utilizing information of a sink device for establishing communication. A source device retrieves the information of a previously connected sink device stored in the source device to reduce data exchanged during a handshaking operation. Information of the sink device not stored in the source device may be stored in the source device for future usage. The source device receives identification information of the sink device via a medium. The source device also searches for capabilities information associated with the identification information in the source device. In addition, the source device encodes the content for transmission to the sink device via the medium in a format compliant with capabilities of the sink device according to the capabilities information.
