3D comb filter
From WikiCover
On August 20, 2007, Toshiba announced the introduction of a second-generation, high-performance 3D comb filter front-end processor targeted at advanced analog and digital televisions, audio/video systems, set-top boxes and other video-processing systems. The highly integrated device provides a complete solution for analog-video processing. It integrates a 3D comb filter for NTSC, a multi-standard 3-line comb filter, 3D noise-reduction functions, a digital multi-standard decoder and 5 Mbits of embedded DRAM for frame-buffer memory in a compact 144-pin LQFP package.
Highlights of the TC90103AFG include the following:
- Built-in, high-performance 3D and 3-line comb filters and 3D Y and C noise-reduction functions - Y/C separation: 3D YCS (3.58 NTSC), 3-line YCS (NTSC/PAL) and band-pass filter (SECAM) - 3DNR: CVBS (3-line comb mode), S-video, YCbCr, RGB
- Adaptive digital multi-standard color decoder; this multi-format decoder capability makes it suitable for use in a worldwide chassis.
- Adaptive multi-standard detection and sync processing
- 5 Mbits of embedded DRAM for frame-buffer memory
- 10-bit and 8-bit analog-to-digital converters to support various input interfaces, including CVBS, S-Video, YCbCr and 10-bit 4fsc digital CVBS
- Digital ITU-R656 and ITU-R601 output for high-quality pictures
- Signal-/noise-level detection, data slice functions for world regions (ID-1, WSS, CCD) and a Macrovision signal-detection circuit
- Analog automatic gain control (AGC) with sync AGC and peak AGC
- RGB fast blanking mixer
- Picture-improvement functions: - Y: V enhance, LTI, sharpness, noise cancel, contrast and brightness; - C: take-off filter, ACC, color gain, CTI and noise cancel
- SCART interface support
- Gemstar G-guide support
- I2C bus control
- Power supply: 3.3 volts (V), 2.5V and 1.5V
- Housed in a 144-pin LQFP package (LeadPb-free)
