Development of World’s First Demodulator LSI for HD Television Conforming to DVB-T2 standard by SONY
Sony today made an announcement on development of world’s first demodulator LSI for high definition television that is in compliance to DVB-T2 (Digital Video Broadcasting- Terrestrial 2) standard adopted in the UK. The DVB-T2 is a new standard which improves on the current DVB-T standards through increase in data transmission capacity and enhancement of high definition broadcasts quality through optimization of band frequency. The new modulator LSI incorporates Sony’s proprietary reception algorithm and error correction circuits resulting in highly sensitive reception even in within weak electric fields as well as stable reception of within multipath environments, while reducing power consumption.
The new LSI is also backward compatible to DVB-T standard as well as DVB-C cable broadcast standard helping with flexibility for DVB-T2 set designs, while contributing to miniaturization and a reduction in the number of components. The newly developed CXD2820R LSI supports multiple-PLP, a technology capable of multiplexing plural transport streams adopted in DVB-T2 in a physical layer. The new CXD2820R LSI has a low power consumption of 700mW. The new LSI is targeted to be used in UK models of Sony’s BRAVIA LCD TVs scheduled to be released in 2010.
