Abstract: A multimedia display process executing in a mobile device traps user input signals to allow switching from display of multimedia to another task without requiring manual termination of the multimedia display process by the user.

Abstract: Multiple TRFC connections transport streaming data through a wireless channel, and the difference between measured round trip times of packets and minimum round trip time is used to adjust the number of TFRC connections to fully utilize bandwidth through the wireless channel.

Abstract: This invention relates to the creation of dictionary functions for the encoding of video signals using matching pursuit compression techniques. After an initial set of reference dictionary images is chosen, training video sequences are selected, and motion residuals are calculated. High energy portions of the residual images are extracted and stored when they match selection criteria with the reference dictionary. An energy threshold is used to limit the number of video signal “atoms” encoded for each frame, thus avoiding the encoding of noise. A new dictionary is then synthesized from the stored portions of the image residuals and the original reference dictionary. The process can then be repeated using the synthesized dictionary as the new reference dictionary. This achieves low bit rate signals with a higher signal-to-noise ratio than have been previously achieved.
