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.
Optical disks rely totally on the ability of the pickup to follow and focus on the data track. It is taken for granted that these mechanisms are phenomenally accurate, work at high speed despite being made at low cost and need no maintenance.
UK media regulator Ofcom is calling for a review of public service broadcasting in the light of its report finding rapid growth in streaming viewing, especially among Millennials.
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.
