4 Channel Video and Audio Controller for Security
Applications
TW2837
The TW2837 has four high quality NTSC/PAL video
decoders, dual color display controllers and dual video
encoders. The TW2837 contains four built-in analog
anti-aliasing filters, four 10-bit Analog-to-Digital
converters, and proprietary digital gain/clamp
controller, high quality Y/C separator to reduce cross-
noise and high performance free scaler. Four built-in
motion, blind and night detectors can increase
security system feature.
The TW2837 has flexible video
display/record/playback controller including basic
display and MUX functions. The TW2837 also has
excellent graphic overlay function, which displays
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 TW2837 contains two video encoders with three
10-bit Digital-to-Analog converters to provide 2
composite or S-video. The TW2837 also includes
audio CODEC that has four audio Analog-to-Digital
converters and one Digital-to-Analog converter. A
built-in audio controller can generate digital outputs
for recording/mixing and accepts digital input for
playback. The TW2837 can be extended up to 8/16
channel video controller using chip-to-chip cascade
connection.
