[video] Real Time Video Scaling

[konstantinos_aris@hotmail.com]

Hi all;
I have been thinking on a problem. Some of you might have an idea. 

The problem is : real time 640x480 video scaling without frame buffering. 
Is there a way to downscale(eq: 320x240) or zooming a specific part of 
a screen without performing any framebuffering?? System clock is of 
course 25Mhz.

Note: Pixel loss is not a big deal. You can ignore some pixels if 
neccessary.


Hope to hear some ideas..

See ya,
Cheers,

Aris
