H.264 is an ITU-T standard for videotelephony based on video compression technology. It is designed to provide better compression of video images together with a range of features supporting high-quality, low-bitrate streaming video. H.264 is also called Advanced Video Coding (AVC), and is identical to the ISO MPEG4 Part 10 of MPEG4 standard. H.264 is now being widely used in HDTV ( high definition digital TV ) and HD-DVD video. Since H.264 aims at high-quality video contents at low bit-rates, the encoding and decoding processes require much more computation than most existing standards do. A recommended hardware configuration to play H.264 1080p video smoothly on Windows system is:
  • 2.0 GHz dual core processor or above
  • 1GB of RAM
  • 128 MB video card (Nvidia 6600 series above, or ATI 1000 series above)
