Open Broadcast Systems Open Sources PTP and ST-2110 analysis tool

Open Sourced its internal PTP and ST-2110 analysis tool

Open Broadcast Systems has announced that it has Open Sourced its internal PTP and ST-2110 analysis tool. By doing this, the company aims to simplify measurements and fault-finding in facilities. In particular, it allows for multi-day measurements without the need to make large and unwieldy packet captures.

By supporting multiple network card vendors, the tool also allows for cross-checking results independently. As the tool was developed during the work-from-home portion of the pandemic, it has minimal system requirements and can run on very modest hardware.

Kieran Kunhya, CEO of Open Broadcast Systems, said: “This simple, but powerful tool has been instrumental in developing support for ST-2110 and ST-2022-6 in our C-200 encoders and decoders as well as troubleshooting several faults in real-world facilities. We hope that open sourcing this tool will push the industry toward greater PTP and timestamp compliance outside of a lab environment.” 

It supports the following functions:

  • ST 2110-20 (video) packet arrival time and RTP-PTP offset measurements.
  • ST 2110-30 (audio) RTP-PTP offset measurements.
  • ST 2022-6 (SDI over IP) first packet arrival time relative to PTP alignment point measurements.
