Features
The TW8811 incorporates many of the features required to
create multi-purpose in-car LCD display system in a single
package. It integrates a high quality 3D comb
NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs,
dual scalers for PIP and multi-PIP support, bit-mapped OSD,
TCON, triple DACs and images enhancement functions which
include Black and White Stretch, favorite color enhancement
and edge enhancement. To further facilitate the move to wide
screen displays, it also supports panoramic scaling. On the
input side, it supports a rich combination of CVBS, S-video,
YPbPr, analog RGB as well as digital YCbCr/RGB inputs. On the
output side, it supports both digital and analog panel type with
analog RGB output.
TW8811 also has a PIP (Picture in Picture) function that can
display two sources display simultaneously on single display
window. It also has built-in bit-mapped OSD with acceleration
as well as 16-bit external OSD support.
Analog Video Decoder
• NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N combination),
PAL (60), SECAM with automatic format detection
• Three 10-bit ADCs and analog clamping circuit.
• Fully programmable static gain or automatic gain control for
the Y or CVBS channel
• Programmable white peak control for the Y or CVBS channel
• Software selectable analog inputs allows any of the
following combinations:
- Up to 4 composite video
- Up to 2 S-Video
- Up to 1 YPbPr
• High quality motion adaptive 3D comb filter for both NTSC
and PAL with concurrent 3D noise reduction
• PAL delay line for color phase error correction
• Image enhancement with 2D dynamic peaking and CTI.
• Digital sub-carrier PLL for accurate color decoding
• Digital horizontal PLL and Advanced synchronization
processing for VCR playback and weak signal performance.
• Programmable hue, brightness, saturation, contrast,
sharpness.
• High quality horizontal and vertical filtered down scaling
with arbitrary scale down ratio
• Detection of level of copy protection according to
Macrovision standard
• Supports YPbPr input up to 1080i with sub-sampled
resolution
• Support automatic standard detection for YPbPr input
Analog RGB Inputs
• Triple high speed 10-bit ADCs with clamping and
programmable gain amplifier.
• Up to three independent RGB / YPbPr channels with
corresponding SOG
• Built-in line locked PLL with sync separator
• Allows high resolution components inputs like DTV 480p,
720p, 1080i
