4-Channel Video QUAD/MUX Controller for
Security Applications
TW2824
The TW2824 has four high quality NTSC/PAL video
decoders, dual color display controllers and dual
video encoders. The TW2824 contains 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 to provide various pictures. Four built-in
motion and blind detectors can increase the feature
of the security system. The TW2824 has a flexible
video display controller including QUAD and MUX
basic functions. The TW2824 also has an excellent
graphic overlay function which displays
character/bitmap, box and mouse pointer. The
TW2824 contains two video encoders with four 10-
bit digital-to-analog converters for providing 2
composite or S-video.
Auto sequence switch with 64 queues and/or
manual switch by interrupt
Various channel attribute control
Image enhancement for still image
High performance 2x zoom for horizontal and
vertical direction
Supports save and recall function
Last image capture when video-loss
Extendable to 8-/12-/16-channel video controller
using cascade connection
Path-to-path cascade
Character/bitmap overlay for OSD
16 programmable single boxes
4 2D arrayed boxes for motion result display
Mouse pointer overlay
