How can we make video more appealing to humans? We’ve evolved to live a certain way and this has defined – and will continue to define – our video technologies. MUX founder Jon Dahl talks to us here about the ways in which human physiology drives viewing habits.
Vertical vs. horizontal video, angular resolution and how the typical viewing distances of computers, TVs and other devices affects what resolution we can perceive are all discussed. Jon moves on to frequencies both of audio and video where frame rates and flicker are important and where physics comes into play alongside biology.
Even for the experienced, this talk is bound to bring something new and is a great tour of the fundamentals of the visual perception that our industry relies on and strives to please day in, day out.
This talk was given at Streaming Tech Sweden which is an annual conference from Eyvinn Technology. Streamed on their own video platform, talks are initially available exclusively to all conference attendees, but are released free-to-view during the subsequent year. Free registration is required to watch the videos.
Networking in the cloud, by rights, should be the same in your office but with it’s a lot easier when you’re led through it. From subnets to VPN’s, this talk from AWS makes sure you can get your VPC (Virtual Private Cloud) talking to other parts of your cloud infrastructure and your office.
Starting with the basics and building up, Perry and Tom take us through the IP address allocation, address choices, firewall configuration, security configuration and then on to Direct Connect, VPNs sharing VPC resources and much more.
From the AWS Summit 2019, this is a great talk for those who know networking well and are new to AWS, as well as those who are comfortable with AWS names, but are a little rusty on the finer points of networking.
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
Thursday February 7th, 10am PST / 1pm EST / 18:00 GMT Now available on-demand!
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.
