Live Streaming from Rome - Quick Ustreaming at a Multicam Event

For the past week (and the next), I've been in the Eternal City, helping the Redemptorist community stream their 24th General Chapter. They wanted to share the proceedings in a more immediate fashion with the broader Redemptorist community around the world, and this is probably the best way to do it.

A few months ago, I was approached by the Redemptorists' communications director and asked what kind of equipment he would need to take a live video feed from a multi-camera setup, and broadcast it on Ustream (free streaming = a good solution - you can also use Watershed or a similar paid service if you need it).

Ustream - PC Solution - DV Bridge

I found a great little Analog-to-Digital converter from Canopus, the ADVC-55, and also purchased the ADVC-PSU5V AC Adaptor Kit with it (since the PC laptop the Redemptorists have has only a 4-pin/no-power FireWire port. I've used a variety of DV bridges in the past, and always had trouble with keeping a reliable DV stream into the computer. Luckily, the Canopus does a great job, and has not once caused a blip in the DV stream - it takes composite video in (along with audio, if need be), and converts it to a DV stream over firewire.

I didn't even have to install a driver on the Vista PC, as the DV stream acts as a generic DV-over-FireWire stream. Therefore, Ustream immediately recognized it and put it online.

For audio, we are using an output from the sound mixer, converted from XLR to 1/4" stereo minijack, and it sounds pretty good. You can easily control the volume of the signal either (a) at the board itself, or (b) using Ustream's volume slider. Note, however, that you should listen to the stream so you can see whether or not the sound is clipping. If it's clipping, you may need to use a different signal, or change the input on your computer from mic to line level.

This kind of setup works great for those who have in-house video systems, as it is probably the easiest way to convert analog video (composite, RCA-jack video, or S-video) into a usable source for Ustream, Watershed, and the like.

Jeff,
Great write up on your setup. Would love to see the finished result.

Couple more questions if you have time...

1. Did the order pay for the gear?
2. How many cameras did they have running? Do you know what make/model they were?
3. If more than 1, what kind of video console/mixer did they use?
4. What kind of internet connection did you have?

In reply:

1. Yes, they paid for the converter and the laptop we're using, as well as the cables to connect everything.

2. They have 3 cameras total, and they are part of a closed-circuit tv system in the auditorium (I think they're sony 1CCD models), all on remote control mounts (tilt/pan, zoom, and focus control).

3. They have a very rudimentary switcher. It's not made for live production, but rather video signal routing. At the New Cathedral in St. Louis, we have a much nicer one - it is the Tricaster Studio model.

4. We have a shared T1 - uplink is only 40-50 Kbps, downlink hovers around 800 Kbps. Just enough to handle Ustream ;-)

Advancing the faith.

This is great! Thanks for sharing!

When you used this setup with the separate line-in from sound board, did you have any audio-synch issues? I have read all the Canopus products advertise "audio lock" to keep things in sync, but thought that may only work if you use the audio connections from the canopus (instead of the sound board to 1/4" jack as you have)... Thanks in advance, and great information!

Nope - didn't have any trouble with that. The sound was perfectly in sync the whole time.
