Video Resolution/Color and TX frequency (900Mhz vs 1.3Ghz vs 2.4Ghz vs 5.8Ghz)

I see several threads mentioning better video sharpness and color from higher frequency (2.4Ghz vs 900Mhz and 5.8 Ghz vs 2.4Ghz).

Interference and line of site obsticles aside, does higher frequency video give you better video quality (resolution/sharpness, colors)?

Is this due to newer equipment design or can the higher frequency equipment carry more resolution and color info due to better bandwidth or other factors?

Given no interference, I would prefer 900Mhz and lower for range and gradual signal loss vs complete drop out, but if I can get more video data, I would like to go with the higher frequencies regardless.

I get some of my most beautiful video from my 900 MHZ video systems. The brand of transmitter and receiver has a much greater impact on picture quality than the frequency does. I have tried some 2.4 systems that give a great picture, and some that make a horrible picture no matter what.

Lawmate and the 900 mhz systems that Range, NG hobbies sells are very good quality. Chose based on your frequency requirements, the picture will be good with either 2.4 or 900 MHZ

The teoretical would be 480 TLV for NTSC and 625 TLV for PAL.
Or in resolution terms, 720 * 576, as is a DVD frame.

So would a higher resolution camera like the KPC 650HQ have any benefit? Would a 480 line camera be ideal when pared with higher resolution goggles?

thanks
