[General] I need some help

[Burhan Khalid]

I apologize because my Arabic is still not 100%, but if this has been 
mentioned already, then excuses in advanced:

In order to 'enhance' a video from a lower quality (framerate, film 
quality), you would need to re-interlace it using software that picks 
out color pixels and using a formula that I will never understand, is 
able to 'fill in' the remaining de-pixelated areas in order to give an 
'effect' of enchancement.

In truth, what it does is similar to anti-aliasing and anistropic 
filtering which is done for graphics rendering.

Anti-aliasing is the process of 'smoothing' out the edges of an image by 
increasing the degree of blend with the surrounding pixels; thus making 
them appear smoother when viewed from a wider angle. If you turn off 
anti aliasing, the edges of fonts appear more defined and jagged (this 
would be similar to a 'zoom in' affect at a camera lens).

All that is wonderful, but the point remains that such software:

1. Is very expensive, due to the nature of work.

2. Requires highly specialized components to make it work, due to the 
processing power involved. Some devices go so far as to have a 
'processing chip' that has some of the core math hard coded in the 
registers themselves.  The latest 'fad' in this arena is the 
introduction of GPGPUS (General Purpose Graphics Processing Units), 
since GPUs are highly parallel in nature, they make perfect candidates 
for such tasks. Since they are not specialized (they are mass market 
products), the devices that embed them are relatively cheap; they 
usually come with their own C++ compiler (gcc) and embedded Linux. The 
architecture that employ these GPGPUs is called CUDA (Compute Unified 
Device Architecture).

Example of such hardware is the nVidia Tesla:

Hope that helps somewhat :)
