Method and system for rewriting the bit stream a non-scalable bit stream scalable

摘要

Embodiments of the present invention relates to a method and system for determining selectively quantization parameter based on the coding parameters. In one embodiment, selection of the quantization parameter, also based on the presence of non-zero transform coefficients as well as other parameters. One embodiment relates to using the quantization parameter selected with reference to the transform coefficients, it is rewritten to the bit stream of a single layer multi-layer bitstream. In one embodiment, I want to convert is compatible with legacy devices, the video sequences of non-scalable single-layer and multi-layer video sequence scalable.
