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.
The transformation of the media and entertainment workflow from discrete, server-based silos to software-based environments is well underway. As the industry makes this shift, media companies find that placing a scale-out storage solution at the heart of the IP workflow yields the additional benefits of improved flexibility and cost savings.
John Watkinson puts on his snake-oil-proof clothing and looks at speaker cables. Finally, some clarity behind the myths and magic that surround technical aspects of speaker interconnections.
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 this article we look at how American NTSC video lines and frames relate to each other, and the consequence for their digital derivatives prevalent throughout the world.
More than half of computer users pick the largest size external drive they can afford and then shop around for the best price. Outside of the type of interface, not much else is considered. That may be fine for general purpose computing, but not for professional audio and video.
