An RTL-SDR can work. NTSC is an analog signal using AM modulation. The
higher modulation frequencies just represent more detail in the video
image. They're not necessary to view a black and white lower resolution
version of the video.

Hi Andres,
just had a short look: doesn't NTSC use a nearly 6 MHz bandwidth?
Best regards,
Marcus
Yes, no way with the RTL to catch NTSC, it does in SDR mode only 2.smth MHz
bandwidth.
