Remote broadcast transmitters were once logged and controlled from studios over a standard telephone line, and monitored on a consumer TV. The alarm was the GM calling the Master Control Red Phone.

Digital Audio: Part 12 - Sampling Rate Conversion June 9^th 2021 - 09:00 AM

In real systems the issue of sampling rate conversion arises frequently but fortunately there are plenty of solutions.

Practical High Dynamic Range (HDR) Broadcast Workflows - Part 2 May 4^th 2021 - 09:00 AM

There is a school of thought that suggests increasing the brightness through the contrast control on a television will give a higher dynamic range. However, this doesn’t necessarily increase the contrast ratio. Quantization noise is the enemy of dynamic range and increasing brightness in a system with a low b…

Practical High Dynamic Range (HDR) Broadcast Workflows - Part 1 April 27^th 2021 - 09:30 AM

HDR is taking the broadcasting world by storm. The combination of a greater dynamic range and wider color gamut is delivering images that truly bring the immersive experience to home viewers. Vibrant colors and detailed specular highlights build a kind of realism into broadcast productions that our predecessors could only…

Electricity: Part 3 - AC Systems May 27^th 2022 - 09:00 AM

Here we look at alternating current (AC) systems and how generating AC often requires an intermediate step of converting to DC to improve the efficiencies of AC generators.

Broadcaster D2C Requirements For The 2020s - Part 2 May 24^th 2022 - 09:00 AM

The first part of this article explained the set of requirements that appear in the most modern OTT Services from broadcasters launching their own App-based services in the 2020s. Here we inspect those requirements in the two broad areas of Content Monetization and Content Delivery.

Information: Part 2 - Gaussian Distribution May 23^rd 2022 - 09:00 AM

Information can never be separated from its nemesis, which is uncertainty. The former is only possible by limiting the latter.

IP Security For Broadcasters: Part 8 - RADIUS Network Access May 17^th 2022 - 09:00 AM

Maintaining controlled access is critical for any secure network, especially when working with high-value media in broadcast environments.

Broadcaster D2C Requirements For The 2020s - Part 1 May 12^th 2022 - 09:00 AM

Most national broadcasters in developed countries have app-based OTT services, many of which have been in place for over a decade. Less-developed national broadcasters still rely on YouTube, Social Media platforms, or their own websites to deliver OTT content to their audience.
