Innovative Custom Logic Solutions for Video Switchers
Video producers use switchers to help them create integrated video content for broadcast television and other video productions. Video switchers allow producers to utilize data input from a number of video sources, such as cameras and video servers. Using video switchers, producers can add key visual elements to a video production, including:
- Special effects
- Transitions between video sources
- Picture-in-picture, text, or still images added to existing video
Video switchers consist of a main control panel that acts as the user interface and a rack-unit (RU) of PCBs that performs various functions based upon the producer’s input. Switchers support standard-definition (SD) video, high-definition (HD) video, or both. Also, many studios are in the middle of an upgrade cycle to support the new and faster serial digital interface (SDI) standard—third-generation (3G) SDI (SMPTE 424M). 3G SDI, which runs at 2.97 Gbps, helps a switcher support 1080p resolution on a single SDI link. Figure 1 shows a typical video switcher solution using Altera® custom logic.
