Broadcast transport streams are expected to be robust, standards-compliant, and predictable under stress.
However, real-world contribution feeds, multiplexers, and headends often deviate from ideal conditions.
To address this, VMA Transport Stream Analyser now includes real-time ETSI TR 101 290 monitoring, providing engineers with immediate visibility into transport integrity, timing, and service information consistency.
What is ETSI TR 101 290?
ETSI TR 101 290 defines a set of measurements and error indicators used worldwide to assess the health of MPEG-2 Transport Streams in broadcast environments.
It classifies errors into three priorities:
- Priority 1 – Transport and PSI integrity (critical errors)
- Priority 2 – Timing and conditional access issues
- Priority 3 – Service Information (SI) presence and consistency
These indicators are widely used by broadcasters, network operators, and equipment vendors to detect faults before they impact decoding or service availability.
TR 101 290 Monitoring in VMA Transport Stream Analyser
The TR 101 290 module in VMA Transport Stream Analyser provides continuous, real-time evaluation of the most relevant indicators across all three priorities, with a clear visual presentation designed for operational use.
Priority 1 – Transport & PSI Integrity
Monitored indicators include:
- TS sync loss
- Sync byte errors
- PAT errors (presence and repetition)
- PMT errors
- Continuity counter errors
- PID errors
- Unreferenced PIDs
These checks ensure that the transport stream remains decodable and structurally valid at all times
Priority 2 – Timing & Conditional Access
The analyser evaluates:
- PCR repetition errors
- PCR discontinuity indicator errors
- PCR accuracy errors (±500 ns threshold)
- CAT presence and repetition errors
This allows detection of timing instability, clocking issues, and conditional access signalling problems that may not immediately break decoding but can cause downstream issues.
Priority 3 – Service Information
Service-level monitoring includes:
- SDT actual presence
- NIT actual presence
- EIT actual presence
- EIT other presence
- SI repetition errors
These indicators help verify that receivers can correctly identify services, populate EPGs, and maintain consistent service metadata.
Designed for Real-World Engineering Use
Unlike purely academic implementations, VMA Transport Stream Analyser focuses on practical operational behaviour:
- Errors are latched and counted until explicitly reset
- Visual status indicators show current stream health
- Error counters preserve historical context
- Stream loss and recovery are handled gracefully
- Clear separation between Priority 1, 2, and 3 indicators
This behaviour closely matches that of professional broadcast analysers used in production and monitoring environments.
Not a “Checkbox Compliance Tool”
VMA Transport Stream Analyser is not positioned as a formal certification instrument.
Instead, it is designed as a diagnostic and troubleshooting tool for engineers who need fast, actionable insight into transport stream behaviour.
The implementation covers the most relevant TR 101 290 indicators used in daily broadcast operations, with additional extensions planned.
Available Now
ETSI TR 101 290 monitoring is available in the current version of VMA Transport Stream Analyser, integrated directly into the main analysis workflow.
If you work with contribution feeds, multiplexers, IPTV streams, or broadcast transport streams, this feature provides immediate value with minimal configuration.
