Migrating live and file-based video services to the cloud holds the promise of huge flexibility in deployment architectures, geographical backhaul possibilities, virtually limitless peak provisioning, pay per use pricing, access to machine learning and other advanced intellectual property on-demand, and much more. This migration is still in its infancy and will ultimately drive new cloud business models and partnerships to create viable financial common ground, but there are some critical technical challenges facing video service providers looking to de-risk the move to the cloud.
The legacy gamma adopted in 709 and 240M has recently been supplanted by two more approaches to applying non-linearity to luminance, namely the Hybrid Log Gamma (HLG) system developed by the BBC and NHK and the Perceptive Quantizer (PQ) developed by Dolby.
With viewers demanding to watch what they want, where they want, and how they want, it’s not surprising we’re seeing an unprecedented growth in broadcaster OTT requirements. However, the change in delivery format from traditional broadcasting is providing us with some interesting challenges.
To see how to make computers secure, we have to go way back to see how they work.
Noise shaping performs an important role in digital audio because it allows hardware to be made at lower cost without sacrificing performance, and in some cases allowing a performance improvement.

In the mid 1990s, the north of England was a hotbed of film production, with well-known features such as Brassed Off and The Full Monty all produced within a few years and a few miles of each other. The Northern Media School, then part of Sheffield Hallam University, was literally and figuratively a long way from Los Angeles, but somehow cinematographer Stuart Brereton found a route between the two without ever having intended to.
Standardized QoS/QoE monitoring systems ensure that Sinclair operators can seamlessly aggregate, analyze and troubleshoot all broadcast performance data groupwide. It also builds a solid foundation for future automation.
As 5G mobile networks become more ubiquitous, the Broadcast and OTT industries are looking to leverage the technology’s speed and low-latency advantages for the management and distribution of live content. Tech companies too are now leveraging cloud-based, edge computing services like AWS Wavelength and Google Compute Engine on the AT&T and Verizon 5G network edge to power their own software platforms and help content providers deliver live streamed sports and entertainment events.
