This is driven by the reduction in linear consumption by consumers in the main. I don’t believe that ‘broadcast as a delivery’ (which is really linear delivery) is going fully away but ‘broadcast as a delivery medium’ (RF one way transmission, one-to-many) is very likely to become significantly smaller than it is today. The existing 4G and coming 5G radio solutions are a very viable solution for IP delivery on mobile, and it is very likely that we will not see large scale commercial embedding of ATSC3.0 radios in mobile devices, which might be why there was a growth in automotive ATSC3.0 mixed with 5G usages being demonstrated at the show and after.Įven at a Broadcast show there was a lot of Cloud Technology around at NAB, and in common with other media and video centric exhibitions the amount of equipment based demonstrations being done at the show is reducing considerably, a clear industry sign that software, virtualisation and cloud is the future of video particularly with the move to IP delivery. Those who would like to see the success of ATSC3.0 do say also that mobile delivery is very important to its success, but that requires additional radios in mobile devices that is simply not happening, despite the drive to provide reference software defined radio solutions to simplify that. This is a trend seen by many for mainstream TV delivery, where there are a number of key projects and initiatives that are moving to OTT delivery and indicating a longer term trend of the next decade ( ). What role does a new broadcast standard have in a world where video consumption is moving to a majority on demand and the balance of delivery effectiveness is favouring IP delivery from a consumer perspective. To still be negative about ATSC3.0 though you could say that it may be too little too late. This is a movement that is demonstrated by DirecTV announcements about not obtaining further satellite capacity in favour of OTT as part of a transition away from what has been its bread and butter for years, and the moves of several other operators to bring about a move of their services to IP delivery. IP’ification is the move of TV and video delivery beyond online delivery, to where we have a mass movement of services up the stack and across onto IP OTT delivery. It has one understated characteristics however and that is a change to the transport that provides IP as a native transport option, which offers some quite interesting options for intermixing delivery modes as the world moves to IP’ification. What does ATSC3.0 bring to the TV entertainment sphere? Well if I want to be somewhat critical it brings the digital enhancements of DVB-T2 (somewhat long in the tooth and standard in pretty much the rest of the world) to the US market combined with HEVC and the capability of delivering video using UHD technologies, however this may not be what it is used for as broadcasters in the US seem to be focusing on the service bandwidth reduction capabilities to fit more into less frequencies. At the conference itself ATSC3.0 was declared ‘Ready for Deployment’ which was somewhat old news as it has been already deployed in South Korea in 2017 but that is countered by the somewhat big lack of devices that support the standard outside of Korea. The key change this year though is that actual field tests have actually taken place in the US in May, as well as the beginning of the FCC issuing of licenses. It has been over three months since NAB2019 in Las Vegas which I thought was a suitable time to look back at the event and what has been the key themes that stemmed from it.Ī big focus was ATSC3.0, which is almost a perennial discussion.
