Engineers face new challenges in measuring 12G-SDI signals, which require different techniques compared to those used with SD-SDI, HD-SDI and 3G-SDI signals. Here we will touch on the importance of signal shape, the impact of jitter and the complexities of the different interface formats.
Consumers care less about how content is delivered to their device than about the quality of the experience (QoE) on that device. This means engineers need to rethink how test and measurement tools can best be applied.
Quality control has always been important for all forms of home entertainment content and broadcast material. But now, with the advent of 4K and UHD, QC is an absolutely vital part of the process that can’t be compromised in any way.
The coding efficiency of audio compression is about to improve markedly because of a new MPEG audio standard—MPEG-H. This standard will permit many new and useful capabilities for those involved in television audio.
At NAB 2015, the dominate discussion on the floor and in many technology presentations focused on; Cloud Services, file based workflows, stream and file analyzers, SOA, ESB, Metadata, Big Data, Storage and “when we will be moving to IP?”. Just how close is this transition?
Broadcasters have always checked their networks for performance. There now is a process that enables the testing to include a true QC measurement of the content as it passes through the entire broadcast chain.
