Abstract: A sink device in a Wireless Display (WD) system may establish a user input device control communication channel between a source device and sink device in a WD system to allow the sink device to send device control inputs to the source device. The user input device control communication channel may include a reverse channel architecture referred to as the Wi-Fi User Input Back Channel (UIBC) that has been modified to transport one or more additional input types over UDP. For example, UIBC may be extended to transport voice input and VNC input types.

Abstract: In one example, a method includes receiving, from a user application and with a wireless docking service of a wireless docking communications stack executing on a computing device, a request to discover one or more peripheral functions within wireless communication range of the computing device. The method also includes, responsive to receiving the request, discovering, with the wireless docking service, the one or more peripheral functions without communicating with a wireless docking center. The method further includes consolidating the peripheral functions into a docking session for the user application. The method also includes, responsive to receiving the request, sending a docking session identifier and one or more respective references corresponding to the one or more peripheral functions to the user application.

Abstract: In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

Abstract: Apparatus and methods of using content information for encoding multimedia data are described. A method of processing multimedia data includes obtaining content information of multimedia data, and encoding the multimedia data so as to align a data boundary with a frame boundary in a time domain, wherein said encoding is based on the content information. In another aspect, a method of processing multimedia data includes obtaining a content classification of the multimedia data, and encoding blocks in the multimedia data as intra-coded blocks or inter-coded blocks based on the content classification to increase the error resilience of the encoded multimedia data. Apparatus that can process multimedia data described in these methods are also disclosed.
