MSA-300

The MSA-300 multi-source analyzer provides total control of test parameters on each selected source. An option allows the scheduling of different levels of testing at different times of the day. All A/V essence is fully decoded in real time.

Up to 24 PiPs can be viewed on a virtual screen. The number of PiPs displayed depends on picture size (SD/HD) and video essence type. Video of the sources in the currently viewed screen — one of 12 available virtual screens — is rendered in real time. The multi-PiP display is quickly set up using standard layout formats and can also be customized to meet a user’s unique preferences. Users can even focus in on a full-screen version of any single source under test.

All test and layout settings are remembered, and can be managed by persistent IDs to allow long-term trending in logs.

Analysis/Test Report and History
The MSA-300 provides the following analysis data:

• Test summary of each source at system, video and audio level
• Detailed test message of each error/warning type
• Monthly, daily and hourly test history (error/warning count) over the past 12 months

Stream Capture
Two different stream capture modes are supported:

• Automatic Stream Capture on Error 
  For standard builds, auto capture enables monitoring of one source at a time (avoiding multiple sources having errors at the same time and overwhelming the capture device). Source data captured is saved from three seconds before the error happens and one to 60 seconds after the error happens. If a new error happens during the trailing period, auto capture continues without creating a new capture file.
• Manual Stream Capture
  For large builds, users can set the maximum capture file size, allowing large continuous files to be captured as smaller files for easy offline inspection from a workstation on the same network.

Data Traffic Monitoring and Logging
The MSA-300 monitors and logs the data traffic at the following layers. The status can be overlaid on the corresponding video window.

• IP (loss/gain of sync)
• TS (loss/gain of transport sync)
• Audio/video
• NTSC CC
• ATSC PSIP
• SCTE-35
• DVB Teletext (ETSI EN 300 472 or ETSI EN 301 775)
• DVB VBI VPS
• DVB VBI WPS
• DVB VBI AMOL
• DVB VBI TVG2X
• DVB VBI CopyGuard
• DVB VBI VITC

There is an option to show the PIDs of applicable traffic on screen. The order of the audio ES can be configured according to either the PID value or the position in the PMT table.

The MSA-300 logs up to 16,000 events daily, including:

• Input signal status
• RTP errors
• ETR sync errors
• ETR continuity counter errors
• Audio/video buffer overflow
• Frozen video
• Black video
• Video resolution change
• Video DAR change
• Silent audio
• Clipping audio

Up to 30 days of traffic histories are kept and logs can be forwarded to syslog server or SNMP server.

Table Analysis
A table analysis feature shows detailed syntax elements of all known tables and descriptors, and provides a Hex data view for debugging and analysis.
