Abstract: A receiver, transmitter, and method for a dynamic forward error correction (FEC) are provided. In one embodiment, the method includes: 1) transmitting frames of data during a streaming session according to a FEC repair rate, each frame being contained in a plurality of source packets and having at least one repair packet; and 2) changing the FEC repair rate at least once during the streaming session based on at least one of a number of unrecovered source packets and a number of unused repair packets.

Abstract: Systems and methods for multiplexing audio/video data and generating transport streams for WiFi network with reduced latency for real time playback at a remote device. A virtual presentation clock reference (PCR) representing a scheduled transmission time of a transport stream packet at a transport stream multiplexer is calculated based on the network transmission rate and generation of the data packets. The virtual PCR is compared with the corresponding system PCR to derive a time difference. Based on the time difference, the transport stream multiplexer is configured to adaptively drop packets or throttle packet generation so as to synchronize the playback of audio/video data on a sink device with the generation of interleaved audio/video packets.

Abstract: A graphics server and method for managing streaming parameters. One embodiment of the graphics server includes: (1) a real-time bandwidth estimator (RBE) configured to generate a bandwidth estimate for a network over which a rendered scene is transmittable, (2) a quality-of-service (QoS) manager configured to generate streaming parameters based on the bandwidth estimate, and (3) a graphics processing unit (GPU) configured to employ the streaming parameters to at least partially prepare the rendered scene for transmission.
