Bridge probes gain transport-stream playout for closed-loop testing

VB330 and VB220 monitoring probes can now originate stored SPTS or MPTS signals and analyse the resulting IP transport path.

Bridge Technologies has added transport-stream playout to its VB330 and VB220 probes. A probe can transmit stored single-program or multi-program streams over multicast or unicast IP, loop the material continuously and monitor the result.

The company specifies up to 12 simultaneous streams at as much as 100 Mbit/s each. Aggregate throughput is stated as 1 Gbit/s, or 2 Gbit/s when SMPTE ST 2022-7 protection is used. Constant- and variable-bit-rate streams are supported, and PTP can provide timing.

Why it matters

Generating and analysing signals in the same probe can speed acceptance tests, fault reproduction and resilience checks without a separate playout server. The announcement does not specify whether the function is a licensed option, which firmware introduces it, or how accurately the system reproduces timing and jitter under maximum load.

What we know

VB330 and VB220 probes can play SPTS and MPTS files over multicast or unicast IP.
The published limits are 12 streams, 100 Mbit/s per stream and up to 2 Gbit/s with ST 2022-7.

What remains open

Licensing and firmware availability were not detailed.
Independent timing, jitter and saturation tests have not been published.
