Consider one of them (H.264) - an evolutionary species from M-PEG-4. The superiority of the evolutionary form of H.264 is that today it "works" on television (HDTV), showing high definition, and is much better than its predecessors, achieving the clarity quality of its improved function - increased stream compression. There is a smoother transition of colors, and a clear transfer of small details. Another advantage of the improved compression is the free up space for collecting archives by 30%, which is significantly higher than the M-PEG-4. The freed up space on the hard disk is an additional place for a video recording surveillance system, which often becomes a limiting factor in the registration of video surveillance.
