Broadcast For IT - Part 20 - IP Systems August 28^th 2018 - 01:00 PM

In principle, IP systems for broadcasting should not differ from those for IT. However, as we have seen in the previous nineteen articles in this series, reliably distributing video and audio is highly reliant on accurate timing. In this article, we investigate the key components needed to build a reliable…

IP Explored - ST2110 and ST2022 August 28^th 2018 - 11:00 AM

As broadcasters accelerate IP migration we must move from a position of theory to that of practical application. Whether we’re building a greenfield site or transitioning through a hybrid solution, simply changing SDI components with analogous IP replacements will not achieve full COT’s goals and the benefits associated wit…

Broadcast For IT - Part 19 - Why Use IP? August 21^st 2018 - 01:50 PM

Moving from the luxury of dedicated point-to-point connectivity in favor of asynchronous, shared, and unpredictable IP networks may seem like we’re making life unnecessarily difficult for ourselves. However, there are compelling reasons to make the transition to IP. In this article, we look at the primary motivation for moving t…

Storage Drives for Audio Production August 17^th 2018 - 11:00 AM

Audio can be edited these days on virtually any personal computer. Professionals, however, need to understand storage drives in order to get the best results. Here’s what to look for when buying drives for audio editing.

Broadcast For IT - Part 18 - Quality Control August 14^th 2018 - 08:00 AM

Quality Control is one of the many areas where IT and broadcast use similar terms, but the meaning is quite different. Whereas IT focuses on guaranteeing bit rates and packet delivery to improve quality of service and hence quality of experience, video and audio quality is based on satisfying the…

Broadcast For IT - Part 17 - Compression Formats August 6^th 2018 - 01:50 PM

The bewildering number of video and audio compression formats available is difficult for those new to the industry to come to terms with. For broadcast engineers and IT engineers to work effectively together, IT engineers must understand the formats used, the legacy systems still in place, and the reasoning behind…

Video Over IP - Making It Work - Part 3 August 2^nd 2018 - 11:00 AM

Point to point connections dedicated to delivering video and audio signals have dominated the broadcast industry since the 1930’s. But migrating to IP is compelling engineers to think differently about packetized signal distribution. In this article we investigate the potential sources of congestion and the effects of buffering.

Broadcast For IT - Part 16 - Video Compression July 30^th 2018 - 01:00 PM

To deliver efficient media solutions IT engineers must be able to communicate effectively with broadcast engineers. In this series of articles, we present the most important topics in broadcasting that IT engineers must understand. Here, we look at compression, why, and how we use it.

Broadcast For IT - Part 15 - Digital Audio July 23^rd 2018 - 01:00 PM

Audio is arguably the most complex aspect of broadcast television. The human auditory systems are extremely sensitive to distortion and noise. For IT engineers to progress in broadcast television they must understand the sampling rates and formats of sound, and in this article, we delve into digital audio.

Video Over IP - Making It Work - Part 2 July 19^th 2018 - 11:00 AM

Timing is the most fundamental aspect of broadcast television. From the early days of tube cameras, to modern OLED displays, timing continues to play a crucial role for maintaining an optimal viewer experience. Picture stutter and breakup are just a few of the symptoms of synchronization and timing errors.
