SGI: Video

My VBOB definitely has 2 SD inputs (labeled 1,2) and 2 HD inputs (also labeled 1,2).
The documentation refers to Link A and LinkB for SD and HD.
Are LinkA,LinkB only meant for aggregating bandwidth onto a single stream, or are they supposed to be useable as separate streams ?

If they are usable as separate streams, then how are we supposed to access it via OpenML?

mlquery only shows 1 SD input jack and 1 HD input jack.
why does mlquery not show the 2nd SD/HD jacks ?



I am starting with some sample OpenML code from the OpenML tardist on nekochan's ftp site.
I will be morphing it into something cooler over time...

you can track progress here...

I think the closest we've got to a VBOB expert here is uunix, speaking for myself I've never been able to get mine to work properly...

Thanks for the honour Vishnu , but it may be miss-placed somewhat.

My VBOB usage has been strictly limited to using it with discreet products and if I get signal present output when I serial into the VBOB I'm generally happy.

What I do know, you can see serial 2 is receiving something by console access v --> s
Also in the init.cfg of a discreet product you can set the video line to serial1 or serial2 but not serial1and2 like you can with the output.

Probably not very helpful I'm afraid.

I think development of the VBOB was a collaborative effort between Discreet and SGI. A workstation and a VBOB by themselves aren't really good for much. There used to be a webpage or two that described how NBC used Octanes and VBOBs with Discreet products in their coverage of the Olympics around a decade ago, but looking for it now it appears none of that content appears to be around anymore.

multiple links are used for higher fidelity signals. 4:4:4:4 requires two links, for example. That was before 3GHz-SDI was available, which can do 4:4:4:4 over a single link.
