If UHD is going to become a mainstream broadcast medium, we’ll need to be able to monitor, edit and review it. But can we?
With ATSC 3.0 poised to change the broadcast industry’s basic signal, we need to understand this signal is poised between HD and true 4K.
Over the past five years, the ways in which we choose to watch television have shifted dramatically. It wasn’t too long ago that live TV was the only option available to us. We had to make sure we were seated with the television on, at the time our favourite shows and movies were scheduled to be broadcast. If we didn’t, we simply missed them.
Protecting the security of media is sometimes an unresolved issue. The first step to securing valuable content is a thorough review to identify any gaps in a facility’s security plan. Then, implement industry best practices and security layers to safeguard those assets.
IP’s suitability for live broadcasting is no longer debatable. It’s been proven in a variety of real-world global deployments over the past several years. Even so, there’s lingering skepticism around IP and a surprising lack of understanding.
In this series of articles, we will explain broadcasting for IT engineers. Television is an illusion, there are no moving pictures and todays broadcast formats are heavily dependent on decisions engineers made in the 1930’s and 1940’s. In the last article we looked at the incredibly complex relationship between lines and frames for NTSC systems used in the USA. In this article we look at the systems used in the UK and Europe.
The impact of IP on the design of broadcast equipment and infrastructures is profound. Many broadcasters are replacing existing analog, AES3, MADI and SDI ports with a new class of interface for connecting to standard IT switch infrastructure, together with new control mechanisms for connection management and device discovery. In the process, they’re embracing an emerging set of open standards for interoperable, vendor-neutral signal transport.
AlphaDogs is one of the west coast’s premiere post houses, but even they find the prospect of creating UHD projects challenging.
