Abstract
A video codec comprising a processor configured to compute a difference between an original pixel and a prediction pixel to generate a prediction residual, and binarize an absolute value of the prediction residual. A method for video coding comprising computing a difference between an original pixel and a prediction pixel to generate a prediction residual, and binarizing an absolute value of the prediction residual. A video encoder comprising a processor configured to set a number of syntax elements to indicate lossless encoding of some or all coding units (CU) in a video frame, a transmitter configured to transmit a bit stream comprising the syntax elements. A method for video encoding comprising setting a number of syntax elements to indicate lossless encoding of some or all coding units (CU) in a video frame, and transmitting a bit stream comprising the syntax elements.
