ATi今天宣布推出“Theater 310”视频处理器，这种视频处理器支持数字电视接收、PC-DTV（个人电脑数字电视）、机顶盒、数字广播等等方面。

THEATER 310 is able to deal with strong co-channel NTSC interference, burst noise, adjacent channel interference and single-frequency interferers in addition to its multipath canceling capability. Performance in the field has been substantially improved over past generations by optimizing over hundreds of captured RF (radio frequency) signals representing difficult indoor and outdoor reception conditions. Performance improvements are due in part to increased equalizer span, new and enhanced semi-blind and blind equalization algorithms, faster equalizer update algorithms, and improved synchronization algorithms for timing and carrier recovery.

In addition to embedded VSB, QAM, NTSC, and BTSC in one device, the THEATER 310 integrated analog front-end reduces the number of intermediate frequency (IF) components that are required in a DTV. The THEATER 310 eliminates the need for a separate analog IF strip and reduces the digital IF strip component count. Furthermore, THEATER 310 includes an EIA/CEA-909 industry standard smart antenna interface to select the best setting on an optional electronically steer-able antenna to further simplify indoor reception.
