Video: IP For Media Webcast Part II

Posted on 4th February 2019 by Russell Trafford-Jones

Following on from last week’s post part II is here. Wes Simpson looks at use of IP in Remote Production/Remote Integration (REMI) and finished with a panel discussion including Newtek and Grass Valley, a Belden brand.

This video talks about:

Why Broadcasters need networking?
Typical Live remote sports broadcast roles
Overview of video & audio Signal types
HDR & Wide Colour Gamut (WCG)
Data (metadata, scripts etc)
REMI – Remote Integration, AKA ‘Remote Production’ in Europe.
Overview of what tasks can be done at base, what still needs to be done ‘on-site’
Uncompressed formats summary (SDI, 2022-6, 2110)
Slice-based compression
Mezzanine compression
TR-01 for carrying JPEG 2000 & audio
Bonded Cellular
Packetloss & FEC (Forward Error Correction)
2022-7 – route diversity
Typical delays
Plus a panel discussion

Webinar: Neuron – IP Signal Processing for Broadcast Infrastructures

Posted on 28th September 2018 by Russell Trafford-Jones

Date: Wednesday October 3rd, 08:00 BST and 16:00 BST
At IBC, Axon introduced, to much fanfare, “the world’s first Network Attached Processor” and announced two customers to boot. But what is a Network Attached Processor? Why will this solve signal processing needs of IP and hybrid-IP environments?

Peter Schut, CTO of Axon, will explain and answer questions in two sessions, am and pm.

Video: Control Throughput and Latency for Multicast-based IP Routing Systems

Posted on 12th July 2018 by Russell Trafford-Jones

John Mailhot explains throughput and latency in switches and discusses live SDI switching in IP, subscription and control using NMOS 5 and 6. John then takes some time to discuss what ‘good enough’ is for switching time given SDI also has a delay.

Finishing up with network topology and interoperability, this is a great look into some of the details of dealing with 2110.

The SMPTE 2110 family of essence networking protocols is based on multicast flows in the IP network. IGMP (Internet Group Multicast Protocol) is the typical method for endpoints to subscribe to the streams they want, and to leave the streams they no longer require. Concerns have been raised in the industry about the suitability of IGMP for this task, and the applicability of SDN techniques as an alternative means to managing group memberships. Speed of switching signals is a particular concern.
