Nec Full Hd Tv System Chip Emmatm2th/h
NEC Electronics has completed the application in Japan
, North America and Europe-wide HD Digital TV SoC "EMMATM2TH / H" in the development and start selling on the same day the sample.
The introduction of new products will be MPEG2 signal decoding, image display and other functions necessary for digital TV integrated into a system for image processing chip. Its biggest advantage is that: (1) brightness and color o Contrast o "quality control" for the first time is modified to support full high definition "1920x1080 (about 2.07 million pixels)" resolution; (2) with the previous EMMA products and hardware compatibility Therefore, there can still use the MPEG decoding software; (3) In addition to support Japan's wireless industry and commerce federation (ARIB, note) to develop the Japanese ARIB standards, also supports the North American ATSC, European DVB With the Chinese national standard for high-definition Radio and TV Standard. Samples of the new product price 7,000 yen / teeth, is expected to start mass production from the summer of 2008, the scale of mass production of 20 million / month.
In digital TV, at a time when "1366x768 (about 1.05 million pixels)," resolution of the popularity of HDTV panel stage. NEC Electronics in June 2007 introduced a resolution in support of this panel digital TV products. But with the TV to the big screen direction, a lot of TV manufacturers began to introduce integrated "1920x1080" high-resolution high-definition television panels, therefore, can maximize the early development of a high-quality high-definition broadcast television performance EMMA products increasing demands. In order to adapt to market demands, NEC Electronics introduced the new product "EMMATM2TH / H". The product is of quality control in the original EMMA2TH improvement based on a variety of image processing circuits, is a high-performance support full high definition products. Its main features include:
(1) can support full HD picture quality control
Control the pixel brightness, contrast, color, picture quality adjustment for quality control of processing bits per pixel than the original increase 2, the largest median 14-bit processing. Therefore, the original gray level can be increased to 4 times.
(2) software products backward compatible with existing EMMA
Compatible with since 1998 is about 10 years in the development of EMMA products have accumulated high-quality MPEG decoding software. Help significantly reduce the pressure of the user software development.
(3) support for Japan, North America, Europe and China's high-definition broadcast TV standard
Support Japan's wireless industry and the Trade Union Congress (ARIB) standard developed by Japanese ARIB, and the North American ATSC, European DVB, etc. with the Chinese national standard definition broadcast TV standards. There is no need for different procurement sold to different image processing system chips, you can develop a full high-definition digital TV.
(4) improve the external memory bus speed o
External memory connected with the memory bus width from 32 bits to 48 bits. Therefore, compared with the original EMMA2TH, within 1 second of data processing increased from 2.6G to 3.9G bytes bytes.
(5) LVDS output for dual-link extension
Image signal output to the LCD panel LVDS (LowVoltageDifferentialSignaling) circuit extended from the previous single-channel dual-channel. Improved output resolution, and the panel resolution from EMMA2TH of "1366x768" raised to support full HD "1920x1080".
