IP

IP video networks require new types of signal generation and analysis
tools to diagnose typical network problems like packet congestion, and
to stress test infrastructures as they evolve.

Testing SMPTE 2110, ST 2022-7 & 2022-6 IP networks

With both the established SMPTE ST 2022-6, SMPTE 2022-7 and the SMPTE 2110 suite of standards, an entirely new level of test and measurement tools is required. ST 2110 based IP systems employ Precision Time Protocol (PTP) with multiple audio, video and ancillary data flows delivering highly complex interactions between edge devices and switches that you simply do not get with SDI systems.

At this stage the testing of ST 2110 flows with ST 2022-7 protection and PTP is challenging. The big issues are currently around protocol behavior, network jitter, and PTP on these complex networks. Configuring a large IP facility can be challenging, with tens of thousands of IP addresses to be allocated and managed.

PHABRIX is actively developing both handheld as well as rackmount IP enabled Test and Measurement equipment that supports both ST 2022-6, ST 2022-7 as well as ST 2110 video, audio and ANC IP flows. The handhelds can act as IP line-check devices in much the same way that they are used for SDI applications and can also act as IP to SDI gateways. The more powerful rackmount devices can be configured for both conventional Broadcast Operation with a powerful suite of basic IP diagnostics, as well as more sophisticated ‘engineering grade’ analysis that is used for commissioning and debug.
