NAB 2024: Bridge Technologies Develop Unique PTS-PCR Checks and Alarms

NAB 2024: Bridge Technologies Develop Unique PTS-PCR Checks and Alarms tkt1957.com

Building upon their market-leading understanding of IP broadcast, packet behaviour and timing, Bridge Technologies today announce the development of two new PTS/PCR time checks, which will provide even more in-depth analysis of misalignment and timing slippage, and allow for detection of hard-to-identify buffer timing issues, which – under traditional PTS/PCR comparison checks included in as part of the standard TR 101 290 checks  – might previously have been missed.

OSLO, Norway — 19 March 2024

These checks will be available as part of the new version 6.2 upgrade, available for all Bridge Technologies’ probes, include their flagship VB330 IP monitoring probe.

Whilst IP-based broadcast delivers innumerable benefits in terms of audio-visual delivery, the complexity of timing issues associated with IP can cause issues in terms of sync, not only between audio and video, but also additional elements such as subtitles. These individual assets generally maintain their own PTS (Presentation timestamp) within each stream, which can then be referenced against the PCR (Program Clock Reference) to ensure alignment. Whilst clock slippage necessarily constitutes a part of most major IP monitoring systems by virtue of the mandatory PTS Repetition check that forms part of the ETSI TR 101 290 specification, its analysis generally only goes as far as indicating presence of slippage. As such, it lacks diagnostic or predictive power. In SFN-based terrestrial networks or in head-end satellite ingest systems particularly, conventional clock slippage monitoring methods may often prove insufficient.

The two new standards, developed by Bridge, aim to address this issue. Through a more sophisticated understanding of difference values and their interactions and patterns, alarm trigger thresholds can be configured to identify and alert engineers to time slippage skew in much harder-to-detect contexts (including subtitling), and thus predict eventual errors far more promptly and accurately.

Bridge Technologies will be demonstrating the potential of these two new clock checks and associated alarms at the upcoming NAB 2024 show in Las Vegas.

Speaking of the new functionality, Chairman Simen K. Frostad said: “This new PTS-PCR check and alarming system is unique to the Bridge suite of probes, and provides a much greater level of insight into the behaviour of the network and potential timing sync issues. Its development is a function of our unrivalled understanding of packet behaviour, developed over the course of 20 years as we have championed the case for IP adoption in the broadcast industry”.
