This webcast will focus on the fundamentals of colour science as it relates to the motion picture and television industry and then explore how we can take advantage our visual system for improved visual quality.
The webcast covers:
AES67 is a method of sending audio over IP which was standardised by the Audio Engineering Society as a way of sending uncompressed video over networks between equipment. It’s become widespread and is part of SMPTE’s professional essences-over-IP standards suite, ST 2110.
Here, Conrad Bebbington gives us an introduction to AES67 explaining why AES67 exists and what it tries to achieve. Conrad then goes on to look at interoperability with other competing standards like Dante. After going into some implementation details, importantly, the video then looks the ‘Session Description Protocol’, SDP, and ‘Session Initialisation Protocol’, SIP which are important parts of how AES67 works.
Other topics covered are:
Packetisation – how much audio is in a packet, number of channels etc.
Synchronisation – using PTP
What are SDP and SIP and how are they used
Use of IGMP multicast
Implementation availability in open source software

There is so much talk about HDR, wide colour gamut (WCG), ‘Better Pixels’ and all the TVs seem to interpolate motion up to 100Hz or above, that it’s good to stop and check we know why all of this matters – and crucially when it doesn’t.
SMPTE’s new ‘Essential Technology Concepts Webcasts’ are here to help and for the first webcast, David Long will look at the fundamentals of colour, contrast and motion in terms of what we actually see.
This promises to be a great talk and, the chances are, even people who ‘know it already’ will be reminded of a thing or two!
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’
Jigsaw24’s Chief Engineer, Phil Crawley, explains video codecs from the fundamentals up. Codecs touch every part of the broadcast chain and are a vital part of the industry as much as of day to day life. So it’s worth brushing up or learning the basics to help you to fully understand what’s happening with today’s codecs, whether that be HEVC, AV1, JPEG XS or trusty MPEG4.

The Tech Breakfast at Jigsaw24 continue this time with a look at video compression fundamentals. Codecs are a vital part of the industry and almost part of day to day life, so the experts from root6, Phil Crawley and Matt Ward, will help you get a grasp of the basics and understand what’s happening with today’s codecs, be that HEVC, AV1 or trusty MPEG4. All this, plus a pastry and a drink!
In this talk, Color Me Intrigued, given at Demuxed 2017, Vittorio Giovara, Senior Video Encoding Engineer at Vimeo, sheds light on colorspaces – what they are, how and why they work, why we should care about handling edge cases properly. Starting with historical design choices, venturing through current standards such as BT.709, and arriving at modern times with High Dynamic Range, the focus will be on practical applications on the web and in broadcast.
A great primer for those who need it, and great revision for the rest!
