Quick help needed on BNC to S-Video!
 

I have a chance to pickup a used Sony Broadcast monitor. It only has component BNC inputs. Any quality issues as I will be using the monitor for DVX100 critical viewing and NLE color correction? Any good source for adaptor cable from s-video out into component BNC in?

S-Video can be broken out to Luma and Chroma, but not component (R/G/B). If the "component" connectors are luma/chroma, you just need to find or make a breakout for the svid lines to BNC. Otherwise, you're going to need some much heftier adapting (converter box kind of stuff)

Is there a quality loss with a convertor box?

Out of curiousity, what kind of monitor has ONLY component inputs? Are you sure it's not composite or something? It seems rather silly to have only that kind of input.

It's a Sony Sony PHM-20M8U

Several high grade Sony monitors have only YUV (component)
analog input.
Qualitywise - the main reason for useing YUV in is that it has
far higher quality than composite or Y/C (S-video) YUV is a
production "thing" and this signal is not a coded NTSC or PAL
signal but rather three video signals Y (someting like black
and white) and two colour signals U and V both on video
level and not a subcarrier coded signal like NTSC etc.
The DV/DVCAM digital "stream" is also an YUV signal, but
a seriel one (one after the other on one cable) while the
analog YUV (used in and out of a Beta SP etc.) is a parallel
thing (three cables). Some of these Sony monitors can also
use RGB (like in a normal computer monitor) but that is not
the same thing as YUV.
Quality when transcodeing from Y/C to YUV - you wont get the same quality as with direct YUV but with a good (not cheap)
transcoder it well look okey.

PHM-20 is quite a high level monitor, it's better to use a good converter to get out a best possible quality. Maybe it would be better to use firewire to analogue component converter instead of Y/C to analog component. I know company named Miranda makes such things, but there is alot more of them out there.
