Other Bridge Chips
Here are described chips for bridging video protocols.
DVI to CSI bridges are used heavily in the drone industry. Here is a list of https://openhdfpv.org/hardware/cameras/hdmi-cameras-rpi/HDMI Cameras and DVI/CSI bridge boards [7].
Camera Stacks do Bridging
Several companies sell camera stacks. They usually include a sensor board, an adaptor board and a communication board. Some contain a processor board. The communication board is always a bridge chip.
Arducam USB 2/3 Shield is the base board for the Arducam camera stack. They operate at 100 Mhz and both support two cameras. The USB 2/3 version has a maximum pixel width of 14/15 single ended wires. The USB 2 version costs $92 and includes H.262 compression.
reCamera is an open source camera stack. Their stack also includes a MCU processor board, and a nice metal case for cooling the MCU.
FramOS is a camera stack for ndustrial cameras.
Protocol bridges are a low cost, and simple solution to connecting video circuits which use different protocols. Advanced bridge chips provide additional useful functionality.
