With more video decoder devices going from PCI interface to native PCIe®, the design of the video surveillance boards is evolving from PCIe Bridge to PCIe Packet Switch. In response to the trend, Pericom offers PCIe packet switches as a solution to integrate multiple PCIe video decoder devices in a single video surveillance card.
In a multiple video decoder configuration, a PCIe packet switch is used to fan out a single PCI Express port to connect to multiple video decoder devices. The block diagram shows a typical overview of a native PCIe Video Surveillance card. Pericom’s Packet Switches can help expand the connectivity to accommodate the need for multiple video encoders.
