IP networks are delivering outstanding success for broadcasters, both in terms of scalable functionality and flexibility. And the recent NMOS suite of specifications is improving integration and control, with IS-06 and IS-07 accelerating the process.
The effect of OTT-based delivery is wide-reaching, stretching all the way back to the original content production domain and creating new technical requirements and opportunities.
The Streaming Video Alliance has emerged as a primary umbrella body driving technical innovation and standardization across the field, reinforcing its status with new members and projects during the ongoing Covid-19 coronavirus pandemic.
MovieLabs has released the latest Version 1.3 of its enhanced content security specifications for 4K, HDR and premium window content, with additional guidance on disabling debugging interfaces and handling security software updates.
SDI and IP differ fundamentally in their approach to data transport as SDI is circuit switched and IP is packet switched. This provides interesting challenges for us as we start to consider what it means to route IP signals.
Our first Essential Insights is a set of three video episodes in which we discuss transitioning to IP with industry experts. We explore the fundamental challenges during the planning stage. The decisions that need to be made, and the long-term thinking needed to maintain flexibility, scalability and resilience.
The best sampling rate for digital audio is easily established by considering the requirements of the human auditory system (HAS), which is the only meaningful arbiter. Provided that the bandwidth of a digital audio system somewhat exceeds the bandwidth of the HAS, that should be enough.
There are many different requirements and expectations in the field of computer security and it may be as well to set out what some of them are. Computation is everywhere, from the ubiquitous iPhone to the military computer in an underground installation, and it is unrealistic to think that one security approach would suit all requirements. Computer security is also awash with buzzwords and these will crop up here with definitions of what they might mean.
