MPEG-4.10 (H.264) Video

Previously known as “H.26L,” “JVT,” “JVT codec,” “AVC,” and “Advanced Video codec,” ITU-T H.264 is one of two new video codecs, the other being SMPTE 421M (VC-1), which is based on Microsoft Windows Media Video 9 codec. H.264 is incorporated into the MPEG-4 specifications as Part 10.

Rather than a single major advancement, H.264 employs many new tools designed to improve performance. These include:

• Support for 8-, 10-, and 12-bit 4:2:2 and 4:4:4 YCbCr
• Integer transform
• UVLC, CAVLC, and CABAC entropy coding
• Multiple reference frames
• Intra prediction
• In-loop deblocking filter
• SP and SI slices
• Many new error resilience tools
