Background

A doctor is performing microscopic surgery. An in-body camera is capturing the video and an LCD is displaying the surgery site. The doctor is operating by looking at the LCD display. Even a latency of 50 ms will effect the doctor's ability to operate. For this RidgeRun customer, the solution was to feed the video though an FPGA and straight to the LCD to minimize latency.

A police officer has an A/V capture device with an LCD on the back. The police officer occasionally turns on the LCD to verify the camera is working as expected.

What causes latency

ALSA or JACK for audio
