Broadcasters must be able to monitor signals at multiple points across the chain with tools that are error free, lossless and secure. You want to detect any issue, identify where and what the problem is in order to fix it soon as possible. No longer can we rely on just monitoring video and audio signal levels. There is a massive new infrastructure involving multiple stakeholders to observe, to understand, and to diagnose. In the event of a delivery failure, tracking and verifying the source of any issue is important for quantifying potential liability.
The broadcaster should monitor for ETSI TR 101 290 compliance in the transport stream via user-determined properties like service bitrate, black video, audio silence, video freeze, PMT structure, resolution change, audio levels, and color space.
Whenever video or data is manipulated, whether it’s being moved between facilities or run through a process such as encoding or transcoding, error detection is essential. So when (not if) your operator receives an alarm they can quickly identify the source and how to solve it, otherwise everything can get out of control.
TR 101 290 is a technical standard devised by the DVB Group for analyzing the integrity of MPEG transport streams. It tests where different parameters are monitored and measured in either frequency of occurrence or timing variation. The results are displayed on screen as either pass or fail indicators or, in the case of timing, with the use of a scale showing where the parameter’s result is in relation to its maximum allowed value. Other indicators will alert the operator to a pending fault if the values start to come close to the system’s limits.
The Alarms section in the Nimbra Edge main menu provides information about alert notifications within the Edge deployment. These alarms can be triggered by different entities such as appliances or internal components of the Edge deployment. There are four different alarm levels categorized by severity for critical, major, minor, and warning messages.
The Service Overview is a live metrics monitoring tool to perform real-time analysis for the routing service of a particular input stream distributed across Nimbra Edge to reach the final destinations. This tool is accessible via the information overview for each input and output from the main menu.
A visualization graph is presented to display all the nodes involved in the routing service, from the input stream and appliance source, through the intermediate video nodes, and the final output streams at the destination appliances. For each node in the graph, detailed live monitoring statistics are displayed to operators.
It is possible click on each individual node to gather live metrics which includes:
Nimbra Edge includes analytics and monitoring Dashboards services to present live metrics of the different components of the deployment.
Dashboards can be configured for use including:
For advanced debugging purposes, it is possible to see the network topology of the interconnected inputs, outputs, and appliances.
The logs from the deployment can be accessed via the Audit log section under the Settings menu. The logs are retrieved from the appliances and components of the Nimbra Edge deployment to gather any relevant information for management purposes. These logs can be filtered by different criteria.
The list of all internal and external Edge regions configured in the Nimbra Edge deployment can be seen in the Regions section under the Settings menu.
The Nimbra Edge platform includes a service overview with a graphical visualization of the full live media routing workflow from the source to all connected destination appliances. This visualization service overview is complemented with individual live transport monitoring metrics per node and an alarm system that reduces substantially the troubleshooting time for an operator.
