Re: "Broadcast is efficient"
Wow, what an amazing negative response from readers of an IT focused site.
A few additional points that might be worth mentioning:
It is almost impossible to buy large screen monitors for living room use, so many people have a TV even if they don't use it for broadcast TV much. What we really need is actual viewing figures, hmm, I wonder if there is someone who does that?
The number of people actually watching broadcast TV live is only ever going to decline, it is old, done, on its way out whether you like it or not. Live events could be streamed more efficiently over CDNs and/or DSat.
Just as regulations were changed to allow a TV antenna to avoid planning regulations the same can be done for satellite dishes (and already has to a certain extent). DSat can also be used to provide high-bandwidth digital delivery of content to places where broadband connections are more difficult or constrained.
DTT and its extensive, expensive network of transmitters needs to fade away to leave room for more modern content delivery methods.
I recently had to consider whether to replace my broken PVR, it was a tough choice and the only thing that swung it was SWMBO and the quality of ITV Player. ITV programs are the only things we record these days because they are the only ones that are not available on a high-quality stream.
