The main goal of the performed comparison is getting answers on the following questions regarding lossless video codecs:
What codec or codecs are best for video capture and video editing applications?
What codec or codecs achieve the best compression ratio?
What advantages multithreading gives to modern codecs supporting it?
Only absolutely lossless codecs were studied in this comparison. Only progressive test video sequences were used.
Was tested folowing codecs:

Based on tutorials by the authors in several forums, introduces the underpinnings of compression for still images (JPEG), video teleconferencing (H.261 and H.263) and video storage and broadcasting (MPEG-1 and MPEG-2); and briefly describes the next generation of audiovisual coding standards such as MPEG-4 and MPEG-7. Emphasizes foundations such as predictive coding, transform-based coding, motion estimation and compensation, and entropy coding. Suitable for self-study by engineers or as a supplementary text in a graduate course, and assumes no prior knowledge of image or video compression theory or architecture, but some background in high-level hardware design.

Your Microsoft Xbox is a great gaming platform, but it also has the capability to do much more. What a bargain it would be if you could use it as a digital media player, serving up MP3 files across the network, perhaps with nice videos on the high-definition outputs. All this becomes possible with just two things. First, you need to get a copy of the free Xbox Media Player, which lets you play DVDs, Internet Radio, MP3 files, etc. Second, the hard part: you need to get an Xbox Modchip, which lets you bypass Microsoft's security restrictions and do as you please with your hard-purchased computer.
