In the fourth and final part of this series, we wrap up with an explanation on how PTP is used to support SMPTE ST 2110 based services, we dive into timing constraints related to using COTS (Commercial Off-The-Shelf) hardware, i.e.: servers.
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.
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”.
HDR offers unbelievable new opportunities for broadcast television. Not only do we have massively improved dynamic range with the potential of eye-watering contrast ratios, but we also have the opportunity to work with a significantly increased color gamut to deliver vivid and highly saturated colors.
