Live sports productions are the natural home for HDR. The increase in luminance latitude combined with extended color space delivers an immersive experience never before witnessed by the home viewer. But backwards compatibility must still be maintained for legacy SDR audiences.
In the previous article in this series we looked at advanced server security and how the controller within a hard disk drive or SSD can be vulnerable to hacking even with the most advanced firewalls and anti-virus software. In this article, we delve deeper into the remedies and how Lights Out Control further ensures safe server operation.
A major development has happened in the broadcast industry with the adoption of software running on COTS servers for processing uncompressed real-time video. Up to recently, this had not even appeared on the radar, but new technology evolution and innovation has now made software COTS for broadcasters a reality.
There is always a cacophony of noise around the big tradeshows; at NAB this year Telestream made its voice clearly heard with the first showcase of OptiQ Channel, a new and radically different one-click channel creation live service for cloud environments.
Broadcasters continue to see the benefits of IP and many are integrating piecemeal to build hybrid SDI-IP systems. At a first glance, monitoring of hybrid systems may seem to be just an extension of existing practices. However, the complex interaction of SDI and IP signal levels, buffers, and timing conspire to provide interesting challenges rarely seen in broadcasting.
In this series of three articles, we investigate the underlying aspects of computer server design for high value security and 24-hour operation. In the first article we look at advanced server security, in the second article we understand how servers are controlled, and in the third article we gain a deeper understanding of virtualization and the benefits for secure operation.
HDR Profiles - Pros & Cons. An obstacle to HDR adoption has been figuring out how legacy SDR TVs should display an HDR signal. There are about 1.6 Billion TV sets world-wide and 300 Million TV sets in the US.
A long chain of events is needed to see a color picture on a TV set. Only by considering every link in the chain can we strengthen any weak links.
