Abstract: A system includes a circuit having a plurality of electronic function blocks interconnected in series, a power source unit coupled to the circuit, for supplying power to the plurality of electronic function blocks, and a control unit coupled to each of the plurality of the electronic function blocks and to the power source unit. The control unit is configured to monitor activity levels of each of the electronic function blocks, and adjusts the activity level of each of the plurality of electronic function blocks. The control unit determines a voltage level suitable for the corresponding adjusted activity level, and adjusts the power supplied to each of the plurality of electronic function blocks in order to achieve the corresponding determined voltage level at each of the plurality of electronic function blocks.

Abstract: A method for encoding video for streaming includes receiving a plurality of sequential image frames generated by a 3D graphics rendering engine. Graphics rendering contexts are obtained, including pixel depth map, rendering camera parameters, and camera motion from the 3D rendering engine. The method next entails selecting key frames among the plurality of sequential image frames, interpolating non-key frames via 3D image warping, and encoding all key frames and warping residues of non-key frames. The system is implementable on a server linked to a mobile user device for receiving the encoded frame data. The mobile user device is configured to decode the encoded frame data and display a corresponding image to a user of the mobile user device.

Abstract: For transmitting digital video information over a network such as the Internet, a hybrid coding scheme (FIGS. 9-18) with wavelet I frame coding and H.263 predictive coding produces a robust, low bit rate video coding scheme. A new packetization method analyzes macroblock level dependency structure (FIG. 19) and packetizes the bit stream so as to minimize dependencies between packets and thereby minimize packet loss damage.

Abstract: Among the embodiments of the present invention is a system for transmitting real-time continuous media information over a network. This continuous media information includes at least video or audio. A communication channel connects a server and client for communicating the continuous media information from the server to the client. This continuous media information is reproduced at least in part at the client during the communication from the server to the client of such information.
