The TW2834 has four high quality NTSC/PAL video decoders, dual
color display controllers and dual video encoders. The TW2834 contains
four built-in analog anti-aliasing filters, four 10-bit Analog-to-Digital
converters, proprietary digital gain/clamp controller, high quality Y/C
separator to reduce cross-noise and high performance dual scaler. Four
built-in motion and blind detectors can increase the feature of a security
system. The TW2834 has a flexible video display controller including basic
QUAD and MUX functions. The TW2834 also has excellent graphic overlay
function that displays character/bitmap for OSD, single box, 2D array box,
and mouse pointer. The built-in channel ID CODEC allows auto decoding
and displaying during playback and the additional scaler on the playback
supports multi-cropping function of the same field or frame image. The
TW2834 contains two video encoders with four 10-bit Digital-to-Analog
converters for providing 2 composite or S-video outputs. The TW2834 also
can be extended up to 8/16 channel video controller using chip-to-chip
cascade connection.
