NMOS is the open standard for multiple vendors co-operating on a broadcaster network, particularly ST 2110, to announce new devices and configure them. Acting as both a database but also a way of easily describing settings to be shared between systems. Often new ST 2110 systems are specified to be NMOS IS-04 and IS-05 capable.
NMOS IS-04 is the name of the specification which defines discovery and registration of devices while IS-05 describes the control of said devices. It’s very hard to run a SMPTE ST 2110 system without these or a proprietary protocol which exchanges the same information. It’s not practical to manage any of these tasks at anything more than the smallest scale.
John Mailhot from Imagine Communications delivers a concise summary of these technologies which may be new to you. He explains that an SDP will be generated and John reviews how you would read them. John explains that the stack is open source with the aim of promoting interoperability.
John takes the time needed to look at IS-04 and IS-05 in terms of practically implementing it at the end of this short talk.
ATSC 3.0 is the major next step in broadcasting for the US, South Korea and other countries and is a major update to the ATSC standard in so many way that getting across it all is not trivial. All terrestrial broadcasting in the US are done with ATSC as opposed to many other places, including Europe, which use DVB.
ATSC 3.0 brings in OFDM modulation which is a tried and tested technology also used in DVB. But the biggest change in the standard is that all of the transport within ATSC is IP. Broadcasters now, using broadband as a return path, have two-way communication with their viewers allowing transfer of data as well as media.
In this talk from Imagine Communications, we talk a look into the standard which, as is common nowadays, is a suite of standards. These standards cover Early Alerts, immersive audio, DRM, return paths and more. We then have a look at the system architecture of the ATSC 3.0 broadcast deployed in Phoenix.
South Korea has been pushing forward ATSC 3.0 and Chet Dagit looks at what they have been doing and how they’ve created high quality UHD channels to the consumer. He then looks at what the US can learn from this work but also DVB deployments in Europe.
Finally, Yuval Fisher looks at how the data and granularity available in ATSC 3.0 allows for more targeted ads and how you would manage both internally and harnessing it for ad campaigns.
