While there is plenty of talk about disruptive technologies — the SDI-to-IP migration, for instance — that transition pales in comparison to the FCC’s repack of the DTV broadcast frequency spectrum. For a TV station, what could be more disruptive than having to relocate the entire operation to a different RF channel?
When the ATSC 3.0 broadcast television system replaces ATSC 1.0, the local TV station landscape is going to change drastically. Based on this first standardization effort, broadcasters will be able to deliver a hybrid mix of broadcast and broadband content, opening up opportunities for new media types and services, and subsequently revenue.
Broadcasters are reverting to being engineering driven after some years operating as little more than content houses, but this time the focus is more on software than infrastructure. That conclusion emerged from the EBU’s (European Broadcasting Union) fourth annual software engineering conference called Devcon, which started in 2013 in recognition that the industry was becoming more IT focused.
Consumer off the shelf technology (COTS) is providing broadcast TV facilities an economical foundation for technical growth in all directions.
Bonding between fixed and mobile networks has emerged as the latest attempt to bring remote areas up to speed for Internet access and relieve “broadband deserts”.
While the debate surrounding the need for a complete migration from handling video (and audio) as a baseband SDI signal to IP continues, manufacturers of bonded cellular video transmitters say they got the transition started with their camera-mounted systems and are committed to helping their customers move past acquisition and on to the studio infrastructure.
An electrical spike getting into modern digital electronics can stop the show, and maybe a career. That’s one reason why spike-protection power strips are ubiquitous in TV studios. But modern TV transmitters are equally susceptible to power surges. Don’t forget to safeguard your station’s investment in RF gear with proper surge protection and grounding technology.
Experimental Next Generation TV station transmits the first live MLB World Series game broadcast in ATSC 3.0.
