Video capture cards are needed when processing digital or analog video and audio on a PC, Mac, or broadcast equipment based on computing architectures. The cards are the interface between the video sources (that come in over HDMI, SDI, A/V, S-Video, or other connection standards) and the workstation or broadcast gear. In the broadcast market, video capture cards are an ideal way to add graphical elements to the video stream in a workstation environment. They are also often used to condition content for streaming. Capture cards come in multiple form factors including boards to fit in the PCIe slots on a tower PC or PCIe-based equipment, external boxes and even dongle-type devices the use a USB connector on a notebook. These products are distinguished by the number and type of inputs supported and the nature and level of processing in between.
Capture cards utilizing Intel FPGAs support capturing capabilities in both digital and analog video and audio, such as:
- Digital video over DisplayPort, HDMI, SDI and other connection standards
- Analog video over YUV, VGA, NTSC, PAL and SECAM formats are also allowed
- Embedded or separate analog or digital audio channels can be inputed.
- Audio television standard 24 bit at 48 KHz
