NTSC to SDI

[John]

This is a rather generic question, as the standards, and final
requirements, are not really well defined for me to deal with at the
moment.

A company I sometimes work for, sells character generators. They are
analog outputs, and of course, in the broadcast world, that is not
very appealing any more.

I am researching alternatives to some very expensive "black box"
solutions that they have been offered, which will convert the CG
output, to SDI, or HDTV, or if its a better term, digital video. These
boxes are overkill, and overfeatured, and include audio channels,
which do not apply to the CG application in its application.

Many head ends are using these kinds of 'black boxes' as a solution to
the fact that they do analog commercial insertion, while the
broadcasters are quickly moving to digital delivery. A stopgap, but a
popular one nonetheless, at this point in the changeover.

What I am searching for, is information and ideas as to how to create
our own 'black box' that only converts video, more of a custom
solution. The management is convinced this is doable, and so I have
been tasked with finding out how to proceed.

Its not my field of expertise, but I think if I can find the basic
requirements of the circuits, and hopefully the IC building blocks, I
could handle it, or at least find the help I need to provide their
solution.

Again, rather a generic inquiry, as opposed to all the dirty details.
Can anyone point me to a source for such components, or discussions on
this issue?

Just hoping to get a road map, to find out how to proceed.

Thanks very much for any suggestions or references.

Why not make your product directly compatible with the systems your
customers have, rather than try to create a "convertor" box?

The installed base, is very, very large, and so upgrading, or swapping
out, is just not a possibility.

Thanks,

Then you have an upgrade market that someone will exploit, will it be you or
a competitor?

Is the design a single board? If not, hopw about a new board for
the video portion?
