new scopes for HD

[Chris Seguine]

The hamlet hardware scopes are junk.

Their vx software scope is very promising. The interface is ok, it records too which is great, and price is reasonable, even including a pc. Levels were accurate, histograms are nice, pixel chooser is great.

Its similar to the omnitek minus the luts and bitstream decode.

Small problem, it is unusable, at least for HD – 422 or 444.

We tried it with the xena2k, decklink and intensity cards. There is a huge delay in screen updates, seconds, not frames. Around 5 seconds for 444 sources, slightly less for 422 and hdv sources.
This is on a 8core workstation. They said they were having ds problems with the input drivers and would have an update to fix it – this was december, still nothing.

It also currently truncates everything to 8bits.

They have a nice fluff piece on their site by some “DIT” in LA, he said he was using a multibridge. Must have been working with an SD downconvert, no way you can use this for live field monitoring in HD in its current state.

Its not rocket science, convert hex to decimal, plot on graph.

It would be great if it worked.

Omnitek is great, way overpriced, but I rather put money on something with software upgrades than on a dead end leader scope. Leader is the only other scope that shows 444, tek and videotek show 4:2:2 or 0:2:2 stream, not both simultaneously.

Ahhhh!!!! Seconds! Wow. Hopefully they improve this. I’ll have to check it out at NAB.

Thanks,

A setup where computer and a video I/O board act as a scope is too big, consumes too much power and there are too many chains in the link and opportunities to corrupt the signal.

Igor,

I would be interested in where you think the problem could occur to corrupt the signal?

Power consumption I agree with. A hardware scope could consume less power than a computer running with an I/O board
