I think by restrictions he means you have to use streaming sources/apps and hardware that support googlecast. If you own a smartphone or tablet its all you need. It is HD or 4K, looks good blown up to 100+ inches and a lot of content is in DD 5.1. It is not a replacement for disc media quality wise. A bluray or CD will deliver better sound/video. But the differences are getting smaller and smaller.
The restriction part is the apps and content are not like android boxes. In my view this is a good thing. The OTT android boxes use streaming apps too, the most popular one being Kodi. The Kodi app is based around user created ripps of content (illegally) and streamed from overseas servers. It is being cracked down on hard and you have to constantly reconfigure your box to maintain streaming. Remember stealing satellite with the cards? This is the modern equivalent. The only difference is the streams are usually poor quality, or subtitled, or constantly stop to buffer. I wouldnt waste your time. Very buggy.
You dont need to buy a box to try it out. Kodi will run on a PC.
Chromecast/Roku/Amazon Fire etc are all legal, high quality streaming methods. Spotify premium is $10 a month. Netflix is around that too. Its a couple bucks more for 4K streaming.
Yeah chromecast!! I can be the program manager for my own network.
We are 10+ years cable free in my house. You don't miss it after its gone.
Antenna (terrestrial UHF over the air HD broadcasts) and Netflix give me local news and sports with all the content I need. We still buy blurays too and will continue but don't buy CDs anymore. If you didn't know an antenna will get you free local HD content from CBC, Global, CTV etc you're welcome!
Plug your address in here and it will tell you what networks broadcasting in your area over traditional terrestrial antenna. FYI, this form of broadcasting signal is regulated by the CRTC and entirely legal.http://www.tvfool.com/index.php?option=com_wrapper&Itemid=29
