People have been making pictures for both the big and small screens for almost a century. In an industry with a history that long, it’s no surprise that the perpetual search for something new has long been tempered by a certain respect for tradition. Or, to put it another w…
Every three to five years, government delegations from around the globe gather at the Radiocommunication Assembly (RA) and World Radiocommunication Conference (WRC) conducted by the International Telecommunications Union (ITU) — the United Nations (U.N.) specialized agency for information and communication technologies. Their mission is to review emerging technologies, negotiate use o…
Back in the early 1980s, Hugo Zuccarelli demonstrated Holophonics to crowds waiting in long lines at a trade show in Los Angeles. His headphone-based 360-degree spatial audio system was startling in its detail. When the sound of scissors cut a lock of your hair from behind, it was so realistic…
DVB, the consortium developing open technical specifications for delivery of broadcast services, has formally approved its DVB-I specification for delivery of linear TV over IP networks including the internet.
The recent launch of Apple’s TV Plus service bulked up with original TV shows costing $6 billion to produce has disrupted global attempts to unify streaming behind a common set of protocols for encoding, packaging, storing and playing back video delivered over the internet.
As the amount of data in the world keeps exponentially multiplying, a Holy Grail in research is finding a way to reliably preserve that data for the ages. Researchers are now closing in on methods to make data permanent. The problem is there is no way to be absolutely sure…
In the data recording or transmission fields, any time a recovered bit is not the same as what was supplied to the channel, there has been an error. Different types of data have different tolerances to error. Any time the error rate is in excess of the tolerance, we need…
This past summer the NBA did a little experimenting using 5G and mobile phones to cover their summer league. This is not User Generated Content (UGC) by any means. It also was not an off the shelf deployment of 5G and demonstration of its capability.

In the previous two parts of this four-part series, we covered the basic principles of PTP and explained how time transfer can be made highly reliable using both the inherent methods IEE1588 provides as well as various complementing redundancy technologies. In this part, we look deeper into monitoring PTP systems.
