When a significant power increase is not an option, adding Multiple Input Single Output (MISO) diversity offers an attractive path to a stronger signal.
What if a video production could be tailored to each viewer, based on transmitted audio and video essence and data stored in the viewer’s browser? Suppose the browser could receive the content and based on the viewer’s personal data, create an individualized version of the program based on that data?
Moving OTT and IPTV operations onto IP-centric solutions and platforms is both complex and fraught with the chance of error. Survival requires that facility managers and engineers at broadcasters learn to swim in the IP pool. Don’t be afraid to seek help.
In the previous articles, we investigated IP from a broadcast engineers point of view as it helps us understand IP. In this article, we start to look at audio integration, and how we make IP work with audio signals, and the challenges we need to overcome.
Some engineers can maintain their current SDI systems armed with little more than a foggy memory of how things are interconnected. But with IP networks, such a philosophy guarantees panic if something fails. When it comes to properly documenting an IP network, ignore this task at your peril.
SMPTE ST 2110 is currently in final draft and possibly will soon be published. Different from previous SMPTE standards, SMPTE 2110 is a Family of Standards covering live production based on IP. However, because it is still under wraps in the secret world of committee, there is scant information on where things stand This article will provide some important background.
Growth of online services both from pure OTT players like YouTube and also operator offerings like AT&T’s DirecTV Now in the US and Sky’s Now TV in Europe is creating a boom in associated streaming devices for casting to main screen TVs. At the same time, rising bandwidth and QoS over the Internet, along with availability of suitable TV sets, is propelling this market towards 4K devices, as was confirmed by the latest data from ABI Research. Indeed by 2022 all streaming media adapters shipped in Europe will be 4K capable, according to that study, and by then the worldwide annual total will be 56 million.
Point to point connections with well-designed standards have given broadcaster engineers piece of mind for many years, knowing when they connect one AES-3 audio output to an AES-3 audio input, the two will connect seamlessly and audio will pass without incident. The same can be said of MADI and analogue twisted pair. Signal routing is easy to follow using numbered cabling and system diagrams.
