| Abstract: How does MP3 work? How about MPEG-2, DVDs, Blu-rays, and HDTVs? I'll
talk about the nuts and bolts and big picture of audio and video compression, including psychoacoustics, filterbanks, variable quantization, colorspaces, chroma subsampling, Huffman codes, the discrete cosing transform, and the amazing data-saving technique of blurring. I'll include some demos and a special SNEAK PEAK of my own stateless MPEG-2 inspection and decoding library. |
