LVDS Panel HDTV-Ready Signal Processor

OVERVIEW

The SVPTMAX-32/68 video processor is a highly integrated system­on-a-chip device, designed for the advanced HDTV-ready LVDS
panel TV applications. SVP
advanced multi-standard audio decoders, advanced audio
processors, embedded MPU and HDMI, triple 10-bit high-precision
and high-speed video ADCs, the 7th generation high-performance
multi-format 3D digital comb video decoder that supports NTSC,
PAL and SECAM*, a HDTV sync separator, motion and edge
adaptive de-interlacing engine, and the video format conversion
engine, supporting many output modes.
Trident's DCRE
integrated inside the SVP
cinema-realistic images. The DCRE
advanced 3D-comb video decoding, advanced motion adaptive de­interlacing, object-based digital noise reduction, advanced 7th
generation scaling engine, film mode support, average picture level
(APL), edge smoothing and dynamic sharpness enhancement.
Trident's patented Unified Memory Architecture (UMA) allows
frame rate conversion, 3D comb video decoding, and video
enhancement processing to share the same frame buffer memory.
All these advanced digital processing techniques are combined
with a true 10-bit video data processing for the most optimal video
fidelity to provide the most natural and cinema-quality video
images.
Designed for maximum system design flexibility, SVP
integrates all video interfaces to support converging digital video,
analog video, and PC data applications. The users of Trident's
single chip SVP
many features while maintaining a price competitive advantage
over the existing solution(s).
