Abstract
A method for compressing video data, comprising: determining a compression target for a picture buffer; calculating a unit buffer budget for each compression unit based on the compression target, a size of the pixel array of the compression unit and a bit depth of pixels of the pixel array; receiving the video data; for a kcompression unit of each video picture of the video data: calculating a unit compression cost for the kcompression unit using a predetermined lossless compression algorithm and an accumulated compression cost, comparing the accumulated compression cost and an accumulated buffer budget for the kcompression unit, and selecting compressing the kcompression unit using the predetermined lossless compression algorithm or the predetermined lossy compression algorithm according to the comparison between accumulated compression cost and the accumulated buffer budget; and sending the compressed kcompression unit to the picture buffer.
