H.264 Camera Display Changing And Key Frames

Hi

Our application has groups of 4 cameras that are displayed sequentially moving around the facility perimeter and changing every 3-4 seconds. With H.264 encoding, it could take up to the key frame time (1 second for us) to get a full picture on the screen. Is there a standard solution to this problem such as streaming a secondary MJPEG stream for live view or forcing a key frame at the camera when selecting it for live viewing to allow apparently instantaneous changes?

Sincerely,

Mark...
