NTT Electronics Releases High-Quality Full HD H.264 Encoder/Transcoder LSI
April 20, 2009
Tokyo, Japan - NTT Electronics Corporation, headquartered in Tokyo's Shibuya Ward (hereafter, NTT Electronics), today announced the release of the Matiz-Advance H.264/AVC encoder/ transcoder LSI.
Matiz-Advance is a single-chip encoder/transcoder LSI for professional use that performs real-time transcoding of high-quality video. Since Matiz-Advance's encoding control is compatible with CBR (*1) and VBR (*2), as well as with the optional Capped VBR (*3), it can be applied to a wide variety of video and audio equipment for professional use. Matiz-Advance also has an HDTV-SDTV downscaler and optionally supports flexible encoding control with its seamless bit rate change capability.
An increasing number of digital broadcasting systems are employing H.264/AVC as a video compression format these days because it provides both high compression and high quality video simultaneously. Most professional video equipment has traditionally used MPEG-2, but today's equipment is increasingly using H.264/AVC for applications such as image editing and archiving, which involves recording images, and for bandwidth-constrained services such as satellite broadcasting and IPTV. Matiz-Advance provides the best solution for these applications.
Matiz-Advance transcodes MPEG-2 images into the more compression-efficient H.264/AVC format, effectively reducing video data sizes by 50 percent or less while retaining high video quality. Matiz-Advance is especially useful in applications such as IPTV headends, video servers, and video editors. These applications require high-end encoders that can transcode content distributed and stored in MPEG-2 format into H.264/AVC format. The single-chip design of Matiz-Advance enables a more compact yet high-performance design of equipment.
NTT Electronics plans to add other functions to this LSI, such as closed captioning (*4), which is required for digital terrestrial broadcasting, CATV, and IPTV. This upgrade will be available to customers via a future firmware update.

Supplementary information
Terminology
- *1
- CBR
- Abbreviation for Constant Bit Rate
- Since it provides stable image transmission, it is mainly employed in communication lines. - *2
- VBR
- Abbreviation for Variable Bit Rate
- Storage media, such as DVD and Blu-ray Disc, use this method. - *3
- Capped VBR
- VBR with a threshold value for the maximum bit rate. This method controls the generation of bitrates smaller than the threshold level.
- This method is used for applications where data streams share the bit rates within a limited bandwidth, such as multichannel broadcasting. - *4
- Closed Caption
- A textual video overlay representing the audio within an image stream for the hearing impaired.
