Video solutions for PC platformsProduct Features
The TVP5010 NTSC/PAL decoder and TVP6000 NTSC/PAL encoder interface the analog world of video electronics to the digital domain of PCs. By combining a premier feature set with standard interfaces, these devices enable a new image quality level for video on a PC platform. The TVP5010 is a video decoder that accepts analog video inputs, composite or S-video, in NTSC or PAL formats then digitizes them. It then separates luminance and chrominance information, and outputs digital data in a variety of standard formats. The TVP5010 also provides adjustable contrast enhancement, brightness, saturation and hue control through the I2C bus interface. By offering comb filtering on both the luminance and chrominance paths, the decoder reduces both cross-chroma and cross-luma artifacts while preserving maximally flat frequency response over the entire video bandwidth. This device also features gen-lock circuitry which when used with a compatible video encoder provides accurate color reproduction with nonstandard or unstable video sources such as a VCR. To provide flexible system implementation, the TVP5010 supplies multiple output formats including 8- and 16-bit 4:2:2 and ITU BT.656 format with embedded syncs. The TVP5010 has four analog video inputs for up to 4 composite inputs or 2 S-video inputs. It also has two built-in analog signal processing channels with AGC and dual high speed 8-bit A/D converters for luminance and chrominance processing. The TVP5010 offers superior video performance to the typical lower quality decoders used in PCs. Its outstanding differential gain and phase, luma non-linearity and frequency response provides a no-compromise solution for both consumer and PC applications. The TVP6000 NTSC/PAL video encoder provides simultaneous composite and S-video to televisions and VCRs. The TVP6000 operates in both master and slave modes with 8-bit or 16-bit video port. It accepts digital YCrCb video data in either CCIR or square pixel format and converts into NTSC/PAL analog video. The encoder's flicker filter eliminates objectionable flicker typically generated when displaying computer graphics on an interlaced television. It also provides adjustable overscan compensation (0 – 12%) to ensure the entire graphics display is shown on the television output. A flicker filter and overscan compensation are essential features for reproducing high-quality graphics on a television display. Both encoder and decoder seamlessly interface to the VMI video ports of the TVP4020 (3D Graphics Processor). Together the TVP5010 and TVP6000 offer a competitive advantage to developers of video systems. Both the TVP5010 and TVP6000 will be available in an 80-pin TQFP package.
