  Hello, the HDMI to CSI-2 module with the Toshiba TC358743XBG chip generally has a latency of around 1-2 frames. This latency can vary based on the specific configuration and the processing capabilities of the system it’s integrated with. For most applications, this translates to approximately 16-33 milliseconds at 60 fps, but it could vary slightly.

  If you’re integrating it with a Raspberry Pi, additional processing time on the device may add a bit more latency depending on your setup and any additional processing applied to the video feed.

  @togetherthinking13 Do you know if the latency will be reduced if the input hdmi stream is monochrome rather than color?

  On the TC358743 bridge the added delay is tiny since it streams lines as they arrive. Expect microseconds to a few scan lines not a full frame. Most lag comes from the receiver pipeline buffers scaling or rate conversion. With a clean 1080p60 path into a matching CSI receiver you are near one frame end to end and at worst about two frames around 16 to 33 ms. I keep a motion rich window like cresus on the source during soak tests to spot stutter fast. To verify use a blinking LED or timecode overlay and film HDMI and preview then count the offset
