Hi,



This question concerns a JVC TK-1070U camera connected to a Hauppauge pci framegrabber card.



Specs for a similar JVC TK-870U are here.

A photo of the Hauppauge NTSC/NTSC-J 26552 is here.

The following lines are from mpv in Debian stretch. Reference

[tv] supported norms: 0 = NTSC-M; ... [tv] tv.c: norm_from_string(pal): Bogus norm parameter, setting default.

Suggests that the camera is delivering PAL whereas the card recognizes only NTSC-x. Correct?



Thanks, ... Peter E.

connect the camera to an NTSC monitor and see what happens?

Thanks for the reply.

A Sony Trinitron CVM-1270 is available here. I haven't found specs for it but the manual for the PVM-1353MD and PVM-1953MD is at

On page 13 "Color system NTSC, PAL". Haven't found anything about switching. Appears these monitors recognize NTSC and PAL and switch automatically.

When the JVC TK-1070U camera is connected to the Sony CVM-1270 monitor, it produces an image. Nothing yet convinces me that the camera output is NTSC or NTSC-J recognizeable by the Hauppauge card.

Can NTSC and PAL be distinguished reliably with an oscilloscope? Instructions on a Web page? I havn't found anything specific.

Thanks, ... Peter E.

We are presently using a 30" Sony that switches between NTSC, PAL, SECAM, et.al. as needed. So, this does not surprise me. Also between 100, 120, 220 & 240, 50/60 HZ.

In a few days I'll be at the site again and see what can be learned with the scope.
