Another new video standard, H.264 advances coding efficiency beyond existing MPEG-based technology. Bit rate reduction of up to 70% enables smoother delivery of broadcast quality video. Other features, such motion estimation, inter-prediction, intra spatial prediction, and improved encoding algorithms, result in improved image quality. H.264 is often called H.264/AVC (Advanced Video Coding), since it is identical to ISO MPEG-4 (also known as AVC). H.264 accomplishes two goals: provide good video quality at low bit rates and do it flexibly enough so that a variety of applications work well on different networks. The H.264 standard will likely apply to many upcoming applications. Some of these may include HD-DVD format, the Blu-Ray Disc, US Broadcast TV, MPEGs, Apple Computer's new OS, and Playstation Portable consoles.
New ITU standard for video compression (also known as AVC or MPEG-4 part 10)
H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors. The standard is expected to offer up to twice the compression of the current MPEG-4 ASP (Advanced Simple Profile), in addition to improvements in perceptual quality. The H.264 standard can provide DVD-quality video at under 1 Mbps, and is considered promising for full-motion video over wireless, satellite, and ADSL Internet connections.
A new encoding algorithm that effectively doubles video compression, increasing videoconference quality.
an ITU standard for compressing a videoconferencing transmission based on MPEG-4. Formerly known as "H.26L," it uses Advanced Video Coding (AVC) to achieve up to a 70% reduction in bandwidth over H.263. The encoding scheme is also known as "MPEG-4/AVC" and "MPEG-4 Part 10."
H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a high quality, small file size, video compression standard.
ITU-T recommendation regarding advanced video coding for high-quality motion video applications. This standard is the result of the merging of the ISO/IEC MPEG4 Part 10 AVC and the ITU-T H.26L committees, to avoid duplication of parallel development efforts. In general, H.264 provides quality superior to MPEG2 at about 30 per cent of the bit rate or less. It is expected to fully replace MPEG2 over time. There are two significant versions of H.264: Level 3 provides for mainstream video while Level 4 focuses on HDTV. Significant changes from MPEG2 include 4x4 PEL block-size and what is called foreground-background video coding.
A new format that encodes video at higher quality that MPEG-4 at a particular bit rate.
a.k.a. MPEG-4 AVC A high-compression, digital video standard that offers greater compression than previous standards. Considered an option for transmitting full-motion video over wireless and Internet connections. Jointly developed by the International Telecommunications Union (ITU) and the ISO Moving Picture Experts Group (MPEG). See Also: MPEG-4, ITU, ISO
H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors. It is one of the 3 CODECs that can be used by the Hollywood studios when authoring Blu-ray and HD DVD movies.
The latest ITU standard for video compression. It is based on MPEG-4 and renders roughly equal video quality with H.263, but at half the bit rate (e.g. 256 Kbps instead of 512 Kbps for an H.263 stream. It was ratified in July 2003.
