摘要： A method and apparatus for audio compression receives an audio signal. Transform coding is applied to the audio signal to generate a sequence of transform frequency coefficients. The sequence of transform frequency coefficients is partitioned into a plurality of non-uniform width frequency ranges and then zero value frequency coefficients are inserted at the boundaries of the non-uniform width frequency ranges. As a result, certain of the transform frequency coefficients that represent high frequencies are dropped.

摘要： Methods and systems may provide for receiving a decoded enhancement layer of a video bitstream, wherein the decoded enhancement layer is associated with a previous layer of the video bitstream, and wherein the previous layer is undecoded due to a packet loss condition with respect to the video bitstream. Additionally, an intermediate motion vector of the previous layer may be estimated, and a target motion vector of the decoded enhancement layer may be estimated based on the intermediate motion vector. In one example, an upsample output gate is maintained in a closed state until the target motion vector has been estimated.

摘要： A method and apparatus for performing video compression and decompression using dynamic quantization and/or encoding. According to one aspect of the compression method, an image is recursively filtered into its constituent components each represented by a matrix of coefficients. Next, the level of correlation of a first of the matrices of coefficients is determined. Based on the level of correlation of this first coefficient matrix, one of a first quantization technique and a second quantization technique is selected. The first coefficient matrix is then quantized using the selected quantization technique. According to another aspect of the compression method, an image is digitally filtered into its constituent components, each represented by a matrix of coefficients. At least certain matrices are quantized to generated a first quantized matrix. The first quantized matrix is then recursively divided until the first quantized matrix or each of the resulting submatrices is sufficiently dense or sufficiently sparse. Each of the sufficiently dense matrices are encoded using a first technique, while each of the sufficiently sparse matrices are encoded a second technique.

摘要： A method and apparatus for compressing video signals. The video compression may include row by row horizontal subband filtering of video data representing part of an image, and row by row concurrent vertical high and vertical low pass subband filtering of the results of the horizontal subband filtering. Less than the vertical filter length of rows of results of the horizontal subband filtering may be buffered at a time. The vertical high and vertical low pass subband filtering may include calculating a first result row by adding a first row of a recursion buffer to the results of multiplying a row of results from the horizontal subband filtering and a first vertical filter coefficient, calculating a second result row by adding the first row of the recursion buffer to the result of multiplying the row of results of the horizontal subband filtering and a second vertical filter coefficient, overwriting the first row of the recursion buffer with the second result row, and transmitting the first result row to be encoded.

摘要： A method and apparatus to achieve relatively high quality audio data compression/decompression, while achieving relatively low bit rates (e.g., high compression ratios). According to one aspect of the invention, a residual signal is subband decomposed and adaptively quantized and encoded to capture frequency information that may provide higher quality compression and decompression relative to transform encoding techniques. According to a second aspect of the invention, an input audio signal is compared to an encoded signal based on the input audio signal to detect and reduce, as necessary, distortion in the encoded signal or portions thereof.
