Altera’s 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 Altera® 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 Altera’s 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.
