Format Conversion Reference Design (V1)

The use of this design is governed by, and subject to, the terms and conditions of the Intel® Design Example License Agreement.

Overview

The Intel image format conversion design delivers two-channel high-quality up, down, and cross conversion of standard-definition and high-definition 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 standard definition (SD), high definition (HD), or 3G-SDI (full HD). The converted image is mixed and displayed over digital video interface (DVI). The design uses Intel’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.

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
  • DVI out, support for 480p/720p/1080p (run-time configurable)
  • Software configurable to speed up design cycles
  • High-speed DDR2 memory interfaces
  • Demonstration on Stratix® II GX Audio Video Development kit

Output is run-time configurable to 480p/720p/1080p resolution. For more information on this core, contact your local Intel sales representative.
