- So, if I understand you correctly, you contend that grabbing an
- NTSC signal on a 512x480 x 24-bit frame grabber "offers more than
- NTSC resolution".
-
- How is it possible to increase the resolution of a given signal
- simply by digitizing it at 24-bits (and at less than the commonly
- accepted 640 x 480 resolution, at that)?
