analogue to digital of AV systems

Hi people,

 

I have various BNC feed's that I want to distribute over a HDMI/Cat5 TV system, as well as send through to our main projector, which will take either a VGA or BNC.

Currently we use a phono input into a VERY old computer and use a program to stream the information through and back out via HDMI.

I need to upgrade the computer, as it keeps freezing, however I can not find another program that will take an input and send it out via the secondary screen.

 

It has been suggested to me that arkaos would take an input. If anyone knows of a better program, or indeed how arkaos would take an input, please do help/suggest something.

 

Many thanks.

 

Josh.

if it does have to be software, you could get away with using qlab (probably the free version as long as you set it up each time you start up the program) as this will take a live input from a cheap composite input card/USBand can then output using the computers graphics card, and as long as you are alright with it running on a mac?

 

if you would be happy with a standalone unit then it would be worth looking at Fulsom Image pro's, these will also leave room for any changes in future as they will convert between almost any signal!

CPC have various composite video to HDMI boxes at the budget end of the market. At the other end Kramer, Extron et al have standalone boxes too.

 

If you want to stick with using a computer VLC, as mentioned above, can be persuaded to do this. Screen Monkey may well also be capable, though I haven't checked.

Does it have to be a PC, or would a standalone unit work also?

It doesn't have to be a PC/Mac, but I was thinking that using a PC would give me the versatility I need. Because these systems are using in a multi-purpose venue. We have filming events to club night to accommodate for.

 

Just so you all know, the HDMI goes into a cat5 Expander distributing to 7/8 points/TVs.

 

I think you should be able to setup Videolan / VLC to do what you want to do.

 

It might be worth doing a bit of searching about "streaming live video using vlc"

 

Cheers,

Iv got VLC player on the computer already, however I can't see how to make it accept the video input. Also, if I only used VLC player, what kind of PCI/PCIE card would I need to integrate with VLC player?

using a PC for this is a very bad idea.

 

It will cause significant latency (2 frames minimum, maybe 2/3rds of a second maximum) this will break your lipsync.

 

It will not produce a good quality result, due to the PC failing to properly process the interlacing.

 

It will be more expensive and use a lot more electricity than a standalone converter.

 

I would get something like http://www.tvone.co.uk/1t-vs-658-main.shtml this will give you everything the PC does + more in a low cost, reliable package. (cheaper models are avaiable - but the TVOne stuff is professional quality with proper UK based support. TVone do more basic solutions which just convert a composite to HDMI but this would let you add HDMI video into your system with just a single box doing the source selection and scaling. )

Thanks for the suggestion. iv looked at the scaler and it doesn't look to bad.The only thing I'm concerned about it that to get a good quality scaler, it well cost more than £300+. Although saying that, to get a good program that could process the input it would cost just as much, if not more than the scaler.

I the audio that I would be using, comes straight from the SkyBox into O1V Yamaha sound desk. This does have internal delays which if needs be I could set up instead. If this gives rise to any alternatives you can think of, please do reply. I appreciate any suggestions.

 

Many thanks.

Josh
