Over The Air broadcasters are no longer the only game in town when it comes lớn delivering nội dung khổng lồ viewers. A whole new range of competitors và technologies are lining up to bring nội dung to viewers.

This is not another acronym article, but before we begin let me define a few terms.

OTA – Over The Air, aka plain old television broadcast (ATSC 1.0).OTT – Over The Top – Using broadbvà mạng internet delivered by cable, satellite or IPTV lớn receive sầu programs from alternate providers like Netflix, Amazon, Hulu, etc.ATSC 3.0 – ATSC3.0 is the OTA response to OTT but functioning more like satellite services as a hybrid service using broadb& và mobile carriers for the return path.LTE (4G) – This is the data layer on điện thoại devices và 5G. It provides more bandwidth và is on the horizon. Voice và SMS are still 3G services & LTE/4G/5G are separate radtiện ích ios in the Smartphone device. An effort is being made lớn offer LTE/5G independent of telephone services. This would be great for tablets and other non-telephone devices needing wireless Internet access.

Wi-Fi 802.11ac is the newest Wi-Fi standard in the ever increasing bandwidth battle to cut the cord. This is coupled with the race between carriers to lớn provide the most public hotspots to service the sản phẩm điện thoại users’ thirst lớn stream 4K lớn their phones.

New competition for broadcasters

Technically speaking Wi-Fi và cellular are over the air technologies. But for the purposes of this discussion they will be considered interlopers. Industry purists will only look at traditional television transmission as OTA. So is ATSC3.0 an attempt by broadcasters to give the cable cutters access lớn their miễn phí nội dung in new and improved resolutions? Or is it a way to capitalize on being able lớn deliver OTT products ie Netflix, Amazon & Hulu in addition khổng lồ their regular programming? And if khổng lồ request ATSC3.0 on dem& nội dung needs a separate mạng internet connection then isn’t this just OTT và then what does ATSC3.0 offer? While our cellphone service still suffers, carriers lượt thích Verizon are looking at “wireless FIOS” which is an interesting play on words since the “F” in FIOS is “Fiber”.

5G the next RF path

More bandwidth, not better coverage, just more bandwidth. There have sầu been a number of interesting efforts khổng lồ bring ATSC broadcast onto điện thoại devices and computers. It just doesn’t seem khổng lồ be getting traction. As broadcasters are challenged khổng lồ produce & deliver programming at higher resolutions and transition their infrastructure while waiting for the industry khổng lồ make up its mind about IP., UHD, và the family of K’s, upgrading their transmitters to ATSC3.0 when their nâng cấp khổng lồ digital is barely depreciated with no market insight does not seem practical.

The TV manufacturers are still hurting from their 3 chiều adventure while trying lớn sort out the K’s, UHD & HDR. Now they need ATSC3.0. Is this an embedded technology or does the consumer add yet another STB và compete for one of the HDXiaoMI inputs on the set? Just when OTT access is becoming a feature with the TV, here comes another box.


ATSC3.0 is a suite of standards

So what does that mean to lớn manufacturers? More protocols, more standards, more software development and less interoperability. Let’s not forget the Grand Alliance for HD, 36 approved standards and the introduction of the term “acceptable latency”. Don’t’ get me started on that – there is no such thing as acceptable latency.

So is ATSC3.0 really new and improved? Or is it the broadcaster’s way of cord cutting, a way lớn end run the Cable/Satellite/IPTV guys? But wait, it still needs an Internet backchannel, so is that really cord cutting? And if the offering is interactive sầu or the transactional delivery of nội dung, then an entire backkết thúc infrastructure is needed lớn support that- & it doesn’t exist. Ahh – Opportunity! Actually a well-known broadcast engineer showed me a transaction service for OTA a number of years ago – he was way ahead of himself.

What about the manufacturers?

This is just adding more confusion khổng lồ hàng hóa development decisions. Broadcast và production manufacturers are in business case hell!. File based- Introducing IMF (not Impossible Mission – Yet), Cloud, IP (all of them), SDI 4K và 8K. Will ATSC3.0 require re-tooling or new product development effort? Is it a new delivery format?

The conversations I have sầu with broadcasters & production organizations is how long can they wait before they have to buy something without the nagging concern it’s wasted capital. Manufacturers are stymied in producing next ren products & the engineers are wondering how khổng lồ make it all work together.

The consumer is equally confused và the “Holy Grail” of single đầu vào, single control viewing seems khổng lồ remain elusive. I was at a friend’s place & her 4 year old wanted lớn watch something on TV, I am pretty clever sometimes and offered khổng lồ set it up. It was politely suggested I let my frikết thúc vày it, it was her system & not so straight forward.

OK, a little nostalgia, rabbit ears & roof antennas, takes me khổng lồ my formative sầu years installing antennas on chimneys và aligning to the transmitter. I was fortunate growing up in NY, it was just point at the Empire State Building – Everyone had their antennas there.

Personally, I’d rather see concerted efforts go into improving the chất lượng of program delivery. I see the same pixelization và freezing from OTA signals that I get from cable, which means it’s from the program origination source. ATSC3.0 won’t fix that.
