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 way, directors of photography are very often looking for ways to make pictures look different, and different in a way that’s somehow appropriate.
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.
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 it will work far into the future.
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 to do something. Error handling is a broad term that includes everything to do with errors. It includes studying the error sensitivity of different types of data, measures to prevent or reduce errors, measures to actually correct them and measures to conceal the error if correction is not available or not possible.
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.
Cyber security impacts everyone and every industry. One unifying comment from cyber security experts is the bad guys are mostly winning. The good guys are fighting the good fight and we each need to do our part. One of the more challenging aspects of cyber security is cyber policy, governance, guidelines and training. I call this “good cyber hygiene”.
Each year, as the TVs in our homes grow larger and brighter, DOPs have to wonder how this will affect our craft and the integrity of our images. As it is, HDR is touted as a kind of industry panacea, addressing in an orderly way (more or less) the vastly improved color, highlight detail, and dynamic range, in the latest sets.
