Overview
The video processing reference design shows how the cores provided in the Video and Image Processing Suite can be used to create a complete video system. The design performs format conversion on a standard definition video stream (NTSC or PAL) to output high definition video over a digital video interface (DVI). The design uses Altera's SOPC Builder tools and several of the IP cores, including a motion adaptive deinterlacer, polyphase scaler, mixer, chroma resampler, color space converter, Nios II processor and DDR2 Memory Controller.

Table 1 contains a complete list of the cores that comprise the Video and Image Processing Suite.
| Table 1. Video and Image Processing Suite Intellectual Property (IP) MegaCore®Functions | |
| Core | Description |
|---|---|
| Deinterlacer | Converts interlaced video formats to progressive video format |
| Color Space Converter | Converts image data between a variety of different color spaces |
| Scaler | Resizes and clips image frames |
| Alpha Blending Mixer | Mixes and blends multiple image streams |
| Gamma Corrector | Performs gamma correction on a color space |
| Chroma Resampler | Changes the sampling rate of the chroma data for image frames |
| 2D Filter | Implements 3x3, 5x5, or 7x7 finite impulse response (FIR) filter on an image data stream to smooth or sharpen images |
| 2D Median Filter | 3x3, 5x5, or 7x7 filter that removes noise in an image by replacing each pixel value with the median of neighboring pixel values |
| Line Buffer Compiler | Efficiently maps image line buffers to Altera®on-chip memory |
