Provides a simple overview of your monitored audio, video and data essences that comprise your monitoring group. Using monitoring by exception helps operators and engineers quickly identify issues within the content of a Monitoring Group. Simple red/green indicators provide an alert to the user of potential issues, and they indicate the type of error detected giving more specific direction on the problem to be solved. Simply hovering over the red icon provides additional information on the type of error and clicking on the icon provides more detailed information to allow the user to investigate the problem.
The Inspect 2110 Monitoring Group Details display provides a variety of information on the Video, Audio and Ancillary Data streams within that group. Thumbnails help identify the video content for the redundant ST 2022-7 streams allowing the user to check visually that both streams are identical and not mismatched. The primary versus secondary comparison provides checks on the streams for Content match, RTP sequence number mismatches, and measurements of out of sync deviations allowing the user to determine issues between the streams.
Red/green indicators allow the user to specifically identify the errors within the streams.
Checks on the essence payload and the bitrate of each stream help verify the type and presence of the stream for video, audio, or ancillary data.
Precision Time Protocol (PTP) is the foundation of synchronization within an IP Media network. Inspect 2110 continually monitors PTP on both primary and secondary networks providing information on the Grandmaster ID, message rates for announce, sync, delay request and delay response. The user can setup alarm templates for PTP to alert the user to a Domain Change, a Change in Grandmaster ID and select threshold for the various message rates.
Within Inspect 2110 the Session Description Protocol (SDP) information is used to configure the video, audio and ancillary data essence information for the input configuration. In some cases, the information entered in the SDP may not match the actual video, audio or ancillary data content. Inspect 2110 can perform a comprehensive SDP to Stream content comparison to ensure that the actual content matches that described in the SDP. When differences are detected, easy to read checkmark indicators are used to highlight potential issues that need to be resolved. Inspect 2110 looks at the stream content and the SDP to ensure that the content that is on the media network is what is expected and ensures that it is correct.
The Real Time Protocol (RTP) provides syntax on the sequence of the IP packets carrying the media payload. Inspect 2110 measures the total number of packets received and determines if packets have been lost or arrive out of sequence. Additionally, measurements are made on malformed RTP or ST2110 packets that have been received. The Packet Interval Time is also measured for mean, minimum and maximum values. These values can be plotted overtime in the metric chart to highlight overall network performance trends and to help predict potential future issues.
Inspect 2110 ‘Monitoring by Exception’ allows engineers and operators to perform their day to day tasks and only draws their attention to potential issues when required. The hierarchical approach to the Inspect 2110 indicators and alerts allow Operations and Engineering staff to move from high level indicators down to ever increasing levels of detail on the problem being explored. Should a point be reached where further in-depth analysis is required engineers can, with a single click of the “View in PRISM” button, launch any PRISM on the network to perform deep analysis of the problematic stream. Inspect 2110 automatically configures the assigned PRISM via the API to analyze the video, audio and ancillary data streams of the Monitoring Group of interest. Easy and quick fault isolation and diagnosis, top to bottom.
Inspect 2110 can provide audio and video validation for video and audio measurements. For instance, there are detection algorithms for black or frozen video frames and the user can setup a threshold for detection and can track these errors over time. For audio monitoring the Inspect 2110 can detect silence in any of the audio essences being monitored (option INS21-AVVAL is required for these audio/video validation metrics).
Red/green indicators allow the user to specifically identify the errors within the streams. A log provides indication of the last ten frozen or black sequences events detected and this can also be plotted graphically overtime.
The compliance monitoring packages measures the audio levels in the channels that are present in any of the audio essences that are being monitored. Loudness Detection can be performed on the audio channel groups to ATSC A/85 with Loudness metrics monitored over the last second and over the lifetime of the measurement. These loudness metrics can also be plotted over time for trend analysis.
To further validate the Monitoring Group, operators and engineers can decode the video and audio of a program to allow remote viewing of the content via a web browser. This allows the user to verify the video and audio content (option INS21-RVW is required).
ST 2110-21 Standard for Professional Media Over Managed IP Networks: provides guidance on Traffic Shaping and Delivery Timing for Video. Specifically, CMAX and CINST for the network compatibility model of the sender and VRXFULL for the virtual receiver buffer model. These measurements can be performed by Inspect 2110 and monitored within the metric chart over time.
Inspect 2110 is capable of monitoring numerous metrics and parameters but they may not all be of equal important or relevant to the various system users. The use of alarm templates allows Engineer to customize what is monitored and logged. Users can determine logged items as Critical, Warnings or Informational with the ability to set thresholds and duration for when the alarm is triggered.
The list of alarms can be filtered to allow users to select parameters that are of specific interest to them. Inspect 2110 allows you to filter by Name, Status, Alarm Category, Monitoring Group, Active Alarms or Acknowledge alarms.
This ability to use templates and to filter the alarms allows Engineering and Operations to tailor the system to alert on only what is important to them. Customized monitoring by exception improves the efficiency of the Operations and Engineering team as they will only be disturbed when things that matter to them go wrong.
