Abstract:
A computer-implemented method of uniformly encoding a video stream, the method comprising the steps of:(a) determining, for substantially each data type used in a video stream, a corresponding, type-specific quantization parameters;(b) selecting a first value from a first array of one of the data types used in the video stream;(c) quantizing the first value using the corresponding, type-specific quantization parameters;(d) selecting a second value from the first array of one of the data types used in the video stream;(e) determining a predicted value from the first value and the second value using the corresponding, type-specific quantization parameters;(f) quantizing the predicted value using the corresponding, type-specific quantization parameters;(g) encoding the quantized first value and the quantized predicted value into the video stream; and(h) repeating steps (b)-(g) for substantially all arrays to be encoded in the video stream.
