Thank You

Right I don't know about specific pieces of software but about 9 megaBYTES(72 megabits per second) per second should in theory would handle the following
640x480
16bits
15 frames per second

Thats based on the following calculations:

1 byte can take a number of a number of upto 255

2 bytes can handle a number upto 65025 (255x255 = 65025)

That makes 1 16 bit pixel in 2 bytes

Then 640x480 = 307200
307200 x 2 = 614400 bytes (thats one image)
307200/1024 (1024 (NOT 1000) been the number of bytes in a kilobyte) = 600KB

So one frame is technically 600kb, although in reality it will be a few bytes bigger.

600kb x 15 = 9000 kilobytes perr second.

Divide that by 1024 to convert to megabytes = 8.78906

That how many megaBYTES per second the data transfer is without extra's like packet headers and possible something to say where an image starts and ends....
