LYRAE Monitoring Multiviewer

LYRAE is a TV or Radio programs monitoring solution. It comes with 2 main features:

First, it’s a smart analysis device able to detect issues on the contribution or distribution monitored streams.

It is also a flexible visualisation tool, giving complete freedom to its operator for the composition of the multiviewer screen: Each element can be freely scaled and moved according to the constraints or habits of each customer.

Various Inputs

A TV or Radio program is often transmitted over various platforms: Local SDI contribution, ASI at the output of the multiplexer, terrestrial, satellite, IPTV and OTT…

The integration or numerous physical interfaces as well as the common codecs allows LYRAE to monitor your streams on all the formats you use without requiring extra conversion equipments upstream.

Truely Extensible

LYRAE’s distributed architecture brings two main advantages:

On a last generation powerful server, it is possible to decode up to 30~40 H.264 HD TV services or 8 UHD/4K HEVC services. The distributed architecture allows to remove this limitation by distributing the decoding processes on several servers. It is then possible to compose multiviewer screens as dense as required.

A regular monitoring solution is limited by the sizing of the used hardware at the time of the first installation. If new channels need to be added, reaching the limit of this initial capacity, the whole solution needs to be replaced. With LYRAE, just adding an additional serveur to the initial setup will take care of the decoding of the extra channels.

Ergonomic

LYRAE’s operator is at the center of the monitoring mission and LYRAE has been conceived from start to adapt to the needs of its users.

Also, tools have been added to alleviate the inherent challenges of the monitoring task. For example, when the number of thumbnails on the screen start to be large, it can be difficult to keep track of the channels with alarms. The penalty box (or quarantine zone) allows to set a specific part of the multiviewer for dynamically displaying services with errors. Just a glimpse is enough to check the state of these services.

A Powerful Graphical Engine

Within a single system, LYRAE is able to display multiple multiviewer screens making it easy to setup a flexible multiviewer wall.

Also, the support for UltraHD/4K and even above makes it possible to increase dramatically the density of a multiviewer screen without compromising on the definition of each cell.

The graphical composition flexibility and the numerous display options enable the design of systems completely customised that adapt to the constraints and habits of out customers.

LYRAE Graphic Engine

Designed for easy integration

Monitoring is a vital part of the production system. It is therefore essential that it integrates perfectly with that system.

In order to link the monitoring to the rest of the production infrastructure, LYRAE comes with SNMP support. And when a deeper integration is required, LYRAE provides an API that allows to control the multiviewer and get access to the state of each monitored service.

In addition, a scripting language allows each customer to fine tune the behaviour of the multiviewer. Generation of specific alarms, integration with the external events, displaying custom graphical elements are exemples of what is possible.
