- Automated Node Testing
The AG test room is a quick and easy way to check whether your AG node is sending and receiving good quality video and audio. Note that by no means is it meant as a replacement for the standard QA test carried out by the AGSC staff.
To test your node, follow the steps below:
1. Connect to the 'AGSC Test Room' virtual venue without encryption. If your audio and video is working OK, you will receive:
* An audio feed - playing Beethoven's symphony No.9 repeatedly (we know it's good, but try not to stay too long!).
* A video feed - showing your own video window(s), a video tool thumbnail window and an audio tool window.
2. Tick the 'Talk' checkbox and send some audio. You should:
* Hear your audio bounced back with a slight delay.
* See the INCOMING audio levels go up and down on the remote IGAudio window, according to your own OUTGOING audio levels.
Automatic Test Screenshot
The picture above is a screenshot of the video feed that the AGSC Test node sends to remote nodes. The different parts are explained:
1. Thumbnail video window.
2. Own video window(s).
3. Test node's incoming audio level; should match own outgoing audio level.
4. Test node's outgoing audio level; should match own incoming audio level.
Troubleshooting
A subset of possible problems is listed below:
If you do not receive audio and/or video when connecting to the 'AGSC Test Room' virtual venue, it is very likely that your machine or perimeter firewall is blocking incoming UDP traffic. However, other causes could be:
- a connection via multicast, the multicast routing could be failing. Check your connectivity with the Manchester beacon on http://ulcc.beacon.ja.net/global/.
- a connection using a multicast-unicast bridge, the bridge could be the point of failure, so it is advisable to try a different one.
If the quality of the audio from the Node test machine is low:
- poor network performance is likely to be affecting the quality of audio and/or video, as the audio is fed straight into the AG (i.e. it does not have to be processed by any external hardware or go through wires) and should have good quality on arrival to remote nodes.
- a different cause could be a problem with the connection between your AG audio machine and your speakers/amplifier.
If the first step completed as mentioned above but your own audio is not bounced back to you, it is very likely that your machine or perimeter firewall are blocking outgoing UDP traffic. However, other causes could be:
- the 'talk' button is not ticked.
- the recording device used by your system is not the same as the one you are using or this is plugged into a different port. Check that the outgoing audio level goes up and down according to your voice.
- a connection via multicast, the multicast routing could be failing. Check your connectivity with the Manchester beacon on http://ulcc.beacon.ja.net/global/.
- a connection via a multicast-unicast bridge, the bridge could be the point of failure, so it is advisable to try a different one.
If your own audio is very distorted when played back at your end, the reason could be:
- the connections between your microphones and your echo-cancellation device (or computer) are failing.
- the echo-cancellation device (if any) is not configured properly.
- poor network performance is affecting the quality of the audio and/or video being sent over the AG.
