Nice video, pushes my old radio knowledge to its limits! I've got to say your voice is a little annoying where you stretch out the end of a phrase or certain words and modulate 'up'. 1. As for the antennas, I can see where the broadcasters wouldn't want to incurr costs for extending the range, but wouldn't an antenna help the viewer outside the range get that signal in that situation vs your final suggestion of not needing to screw in a coaxial cable? My current ATSC 1.0 TV definitely benefits from the antenna its hooked to. 2. With the Pluto TV example, you mention its only a 'one way' system so it would eliminate tracking by the broadcaster. Would ATSC 3.0 allow interaction from the viewer's end so I could use Pluto TV's search function? (Example: the ability to type a film name in the Pluto TV screen's search box?). I can look up stuff on PlutoTV on my computer using the search function, but not the SMART television I have.
Thanks for sharing your feedback. It's a way to add drama to the narration. As far as your questions are concerned: 1. Yes, an external antenna would help. The problem is, the modulation and code rate could be set with a minimum SNR of say 36 dB. Even with the best antenna aimed directly at the closest transmitter in the SFN, there's a good chance that the signal wouldn't come in strong enough to surpass a 36 dB SNR in a fringe environment. Also, broadcasters could implement a SFN with MIMO, which would require strong reception of both polarizations simultaneously. There isn't a consumer grade antenna that I'm aware of that could pick up weak MIMO broadcasts in a fringe environment. 2. Yes. The way it currently works is your search request is uploaded to a server, the server processes the request, and then the results are sent back to your device. In an ATSC 3.0 offline scenario, your device would process the search query based on the data it has (In the example from the video, 250 live channels and 5 movies).
@@WNYOverTheAir Thanks, the whole ATSC 3.0 rollout seems to be in flux right now as broadcasters have converted over here in Los Angeles but still questions 'above' the details and methodologies you present here. No TVs available yet either; my local Best Buy's TV staff were not aware of any 'nextgen'-specific TVs just yet, but they know they're coming. I'll probably just wait until the 2027 cut-over period to see how the whole system evolves. Cheers
Great video thanks
