The Broadcast Knowledge

Video: SNMP is Dead

Posted on 24th January 2019 by Russell Trafford-Jones

SNMP has long been widely used in the broadcast industry and is a great example of the industry using a technology which is there but has never quite satisfied all the needs not least security. Here, Rob Shakir and Carl Lebsack from Google explain their dissatisfaction with SNMP and tell of the system, gRPC, Google has written and implemented in response to stream telemetry at a high frequency. As larger facilities move to uncompressed essences over IP, this should solve a number of issues for the broadcast industry.

This talk given at NANOG 73 covers:

SNMP inefficiencies
The requirement for time-accurate data collection
The need for finer granularity
Inability of SNMP to contain large amounts of data
Reasons streaming the telemetry works better
Discussion around deployment of gRPC

Video: Planning an ST 2110 infrastructure

Posted on 23rd January 2019 by Russell Trafford-Jones

In a continuing series of videos which dig deeper than just saying ‘hooray, IP is great’, we look at the onerous task of actually planning and deploying a whole building’s worth of 2110. From the IPShowcase at IBC 2018, Ultich Voigt from Qvest Media explains how they helped Swiss public broadcaster SRG/SSR to build their new facility – the TPC Sports, News & Technology centre.

Ulrich looks at how functions can be centralised and/or consolidated and whilst he talks of the technology standards in use, the highlight here are the workflows achieved.

Topics covered:

Aims of the project
Technical Goals and Standards
How they got experience in using IP ahead of the project
Testing planning & issues rectification
Deciding whether to go ‘Full IP’ and what that means
Dealing with immature product market
Vendor partnerships
Tendering & more!

Video: The Business Benefits of IMF to a Global Production System

Posted on 21st January 2019 by Russell Trafford-Jones

In this talk from Andy Wilson at Northern Waves 2018, we find that IMF, the Interoperable Master Format is not just about technology, but if anything it’s more about improving workflows today with an eye to being the foundation of future workflows and business models.
Doctor Who’s 50th Anniversary release which needed 106 versions for its simultaneous worldwide release forms the example which shows how IMF helps broadcasters reduce duplicate copies, support versioning workflows, maintain quality and much more.

Mastering as a new route to save storage, costs and time – as well as look at automation as part of the process. This introductory session outlines the business benefits and use-cases that the DPP have developed with global broadcasters and online players.
