The TVP5158EVM evaluation module is used to demonstrate the TVP5158. The TVP5158 is a Four-Channel NTSC/PAL Video Decoder with Independent Scalers, Noise Reduction, Auto Contrast, and Flexible Output Formatter for Security and other Multi-Channel Video Applications.
Composite input signal is sampled at 2x the ITU-R BT.601 clock frequency, line-locked alignment, and is then decimated to the 1x pixel rate. CVBS decoding uses five-line adaptive comb filtering for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter is also available. On CVBS inputs, the user can control video characteristics such as contrast, brightness, saturation, and hue via an I2C host port interface. furthermore, luma peaking (sharpness) with programmable gain is included.
All 4 channels are independently controllable. These decoders share a single clock input for all channels and for all supported standards.
TVP5158 provides a glueless audio and video interface to TI DaVinci™ video processors. Video output ports support 8-bit ITU-R BT.656 and 16-bit 4:2:2 YCbCr with embedded synchronization. TVP5158 supports multiplexed pixel-interleaved and line-interleaved mode video outputs with metadata insertion. TVP5158 integrates 4-Ch audio ADCs to reduce the BOM cost for surveillance market. Multiple TVP5158 devices can be cascade connected to support up to 8-Ch Video or 16-Ch audio processing.
The TVP5158EVM was designed for ease of use to minimize set up time while providing an evaluation system for the TVP5158 video decoder.
The TVP5158EVM includes the TVP5158 NTSC/PAL Video Decoder Board Module, a universal 5V power supply and a video data cable that connects to a DM6467 EVM.
It also includes a Windows™ compatible application called WinVCC (Windows Video Control Center). WinVCC communicates with the TVP5158EVM via I2C through a USB port connection and provides the means for manipulating system register settings. This software is provided with the TVP5158EVM.
