Abstract: Times of receipt of start-of-frame indications associated with frames received from multiple image sensors at a video controller are monitored. Time differences between the times of receipt of the frames are calculated. One or more frame period determining parameter values associated with the image sensors are altered if the time differences equal or exceed frame synchronization hysteresis threshold values. Parameter values are adjusted positively and/or negatively to decrease the time differences. The parameter values may be reset at each image sensor when the time differences become less than the frame synchronization hysteresis threshold value as additional frames are received at the video controller.

According to yet other techniques, a PLC detector may be capable of receiving and decoding two or more types of PLC frames (e.g., using different PLC standards).
