NTV Extends Reliance On aQ Broadcast Technology

Canadian broadcaster Newfoundland Broadcasting Company Ltd. (NTV) has extended its reliance on aQ Broadcast technology by adding a new aQ Video Server (aVS) to its monitoring infrastructure.

Sporting a total of 16 ports after expansion, the unit is being used to monitor transmission feeds to and from a variety of different sources and to provide alerts in case of any problem being detected.

aQ Broadcast CEO Neil Hutchins says that after demonstration of the aVS' capabilities last autumn, the NTV team "very quickly realised that it would be a great investment and would significantly transform this part of their broadcast infrastructure. We had the system installed and configured around the multi-viewer, and by December everything was up and running."

NTV is one of aQ Broadcast's oldest and largest customers, making use of QNews newsroom software – which provides a robust and reliable solution for full-scale newsroom computer system (NRCS) functionality – and aVS video servers for many years. aQ’s server hardware and software automation technology support NTV’s news studio ingest, storage and playout, as well as its MCR/transmission storage and playout.

But it was a fortunate coincidence that led to the latest extension of NTV’s utilisation of aQ Broadcast technology. During autumn 2018 aQ personnel were on-site at NTV’s studios to undertake hardware and software upgrades. Whilst on-site their attention was drawn to a completely unrelated issue with a third-party device downstream in the transmission chain for one of the output feeds that was beginning to prompt complaints. An aQ engineer was able to outline the ability of an aVS to provide powerful automatic monitoring and alerting for such incidents – as a result of which a system was swiftly delivered and has now been in use for several months.

The unit was initially set-up with 8 bi-directional ports, redundant PSU and no internal media storage (none is required for this application) in a 1RU chassis. The ports were configured as seven monitoring inputs and one multi-viewer output. Since the initial installation the aVS has been expanded with an additional 8-port card, with one port in use as a monitoring input and the other seven available to support future requirements.

Whilst the multi-viewer output can provide a configurable view of any or all inputs, each input is monitored for a range of error conditions, including signal fault, freeze, silence and more. Once an alert is raised, a message is forwarded to all operational and administrative interfaces, with appropriate NTV staff receiving an immediate notification. The system can also send SMS/text message alerts – a capability which NTV is currently in the process of implementing.

In addition, aVS’ fault monitoring can be used to trigger automated failover switching; it’s not a capability that NTV is currently making use of, but it is available for future use.

NTV Manager of Engineering Dean Sullivan commented: "Prior to the installation of the aVS monitoring server we were dependent upon the Master Control operator to notice any signal loss or degradation across seven different service providers, in different formats and all on separate video monitors. With the installation and configuration of this new aVS monitoring server we no longer require the human element and intervention. The aVS system monitors everything we need, displays the video and any alerts in real-time, and notifies us of the issue via email – both initially and when the issue has been resolved."
