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.
Following a rash of 4K UHD products that hit the market two years ago, cameras with high dynamic range (HDR) capability also began to emerge as a less costly alternative to improving signal quality. Indeed, HDR had a strong showing at the 2017 CES, with different TV manufacturers pledging support for Dolby Vision (PQ) and Hybrid Log-Gamma (HLG) systems in addition to the baseline HDR10 standard.
Transitioning to IP improves flexibility and scalability, both of which are achievable using COTS IT equipment. But can COTS solve every challenge? Or does broadcasting still have some unique and more demanding requirements that need further attention? In this article, we look deeper into the specifics of IP networks for broadcasting.
HDR is a technology that is evolving quickly on the Professional and Consumer side. Like all new technologies, the devil is in the details. There is confusion about the technical aspects of which HDR technique and implementation are best for a given situation.
Humans create their art with the materials available in the era they live in. When French workers created the 151-foot tall Statue of Liberty in the 1870s, they used copper, iron and granite for construction. Five years ago, when a new generation of workers began creating the Statue of Liberty Museum to tell the story of the iconic monument, they employed 8K video and immersive audio, along with physical artifacts, to inspire the 4.3 million annual visitors to the statue site in New York Harbor.
