Taking the worst case scenario

Remote display function in the Remote Control requires a maximum bandwidth when the whole screen changes.

Assuming that on a 640x480 VGA display for a full screen on 16 bit color depth requires around 4 seconds on a 2.5G Edge n/w with 200kbps speed (640x480x2x8*0.20)/(1024x200) considering 80% compression

If we reduce the color depth to 2 bit then it would take 1/8th of that time (half second)

On a QVGA 16 bit it would take 2 sec; for 2 bit 0.25 second

However if there is only certain area in the screen changes transfer will be very minimal

With a better n/w obviously you will see much better result
