摘要： In an encoding process, video data are represented as a bitstream of a quantized base layer and one or more enhancement layers, which capture the difference between a quantized base video picture and an original unquantized input video picture. Due to bandwidth constraints on a communication channel, it may be unfeasible to transmit all enhancement layers. During the encoding process, the enhancement layer data may be adjusted to give transmission priority to information in the enhancement layers that is visually important. Following transmission, the adjustment may be undone during the decoding process.

摘要： A method for decomposing signals into efficient time-frequency representations for data compression and recognition which uses adaptable wavelet basis functions and concentrates a signal or image's information to a higher degree than methods based on the discrete fourier transform, the discrete cosine transform, the standard wavelet transform and known adaptive transform techniques. The purpose of the present invention is to enable data signals and images to be stored and transmitted very efficiently. The time-frequency plane is broken up into subspaces. The method determines the optimum basis function for each of the subspace regions. Basis functions are chosen such that much of the information in the signal is contained in a small number of coefficients. The resulting coefficients form a set that represents the signal in the most concentrated manner.

摘要： Participants in a teleconference may exchange multimedia data, such as audio, video, documents, thumbnails, white board, buddy list, control data, etc., for example. The end-point devices may be located in different locations, may have different capabilities, such as processing power, amount of random access memory, amount of graphics memory, and display size, and the links among terminals may have different bandwidths. A real-time routing server may scale features available, such as video capture/encoding size, video decoding/display size, number of video display windows, quality of video pictures, whether to have thumbnails, etc., to the end-points based on the capabilities of the particular end-point device and/or its link bandwidth to the real-time routing server.
