    摘要: A method for decoding a video frame includes receiving a slice header of at least one of a plurality of slices, identifying a type of a first slice and a type of a second slice, and initializing a first context associated with the first slice and a second context associated with the second slice using one of a first initialization method and a second initialization method. The first initialization method or the second initialization method is selected according to the type of the first slice and the type of the second slice.

    摘要: A system for decoding video including receiving quantized coefficients representative of a block of video representative of a plurality of pixels and dequantizing the quantized coefficients. The system inverse transform the dequantized coefficients using a first one dimensional inverse transform and a second one dimensional inverse transform to determine a decoded residue where the result of the first one-dimensional inverse transform are shifted different amounts using a shifting process based upon the magnitude of the dequantized coefficients.

    摘要: A method is provided for adapting models on the basis of link quality indicators. A plurality of statistical models which predict whether a given data bit in a stream of data bits is in error are first defined, where each model includes an indicator of bit errors in the bit stream used to train the model. The method then includes: receiving a data packet at a receiver in a wireless network; determining an indicator of bit errors for the received data packet; and processing the data packet at the receiver using a model from the plurality of models which correlates to the bit error indicator for the data packet.
