The use of this design is governed by, and subject to, the terms and conditions of the Intel® Design Example License Agreement.
The Intel image format conversion design (V2) delivers two-channel high-quality up, down, and cross conversion of standard-definition (SD) and high-definition (HD) video streams in interlaced or progressive format. This design is verified in hardware, and a demonstration is available from your local Intel® field applications engineer (FAE).
The format conversion design illustrated in Figure 1 implements image format conversion for two channels of video. The design ingests video over two serial digital interface (SDI) channels, which can handle SD, HD, or 3G-SDI (full HD). The format converted images are displayed over SDI. The design uses Intel intellectual property (IP) for SDI and video and image processing functions.
Image format conversion is a commonly used function in various broadcast infrastructure systems, such as servers, switchers, head-end encoders, and specialty studio displays. The need for image format conversion is driven by the multitude of input image formats that must be converted to HD or a different resolution before they can be stored, encoded, or displayed.
Features and Benefits
- Two-channel up/down/cross conversion: Polyphase scaling, motion adaptive deinterlacing, mixing, and frame-rate conversion for resolutions up to 1080p
- SDI input (SD/HD/3G-SDI), interlaced, and progressive support
- SDI output, support for interlaced and progressive outputs
- Software configurable to speed up design cycles
- High-speed DDR2 memory interfaces
- Demonstration on Stratix® II GX Audio Video Development Kit and Arria® II GX Audio Video Development Kit
