Normally, watching TV and Movies is a big part of many people's home technology needs. I'm afraid I will have to punt on this topic, though. I really enjoyed The Tools and Toys Guide to Cutting the Cord, and I think they cover this really well.
They have a lot of practical advice and offer some good cautions about the costs and benefits of being a "cord cutter".
once you’ve cancelled your cable subscription, you may realize that you don’t watch the channels a paid TV service provides enough to warrant the expense.
I feel like I was out in the lead on this one, I've been a "cord-cutter" since 2005. I saw the writing on the wall and when I graduated college, got married and started living in my own apartment for the first time, I didn't ever pay for cable television. I just got the basic internet service, and turned down all the TV packages.
We also never had a home phone because we contacted everyone using our cell phones and never saw the need. But, back to TV, some years we have used an antenna to receive local programming, but it was never very good. Once we got used to watching content streamed over the internet we grew very impatient with the old style of TV. So many horrible commercials! The annoyance of trying to fit in our schedule around a show, or trying to make a video recording solution that worked well on my Windows Media Center PC.
What it comes down to for me is that I don't really watch sports, and I don't watch local news (any more). So, our entertainment needs are currently best fulfilled by Amazon Prime Video, iTunes, and sometimes Netflix. We watch shows and moview on a laptop or an iPad. We chose not to plan our living room around a TV and currently we dont have one at all. We do have a monitor that displays a dashboard of data like the weather forcast, our flickr photos, and our upcoming family calendar events. This could get a streaming box plugged into it pretty easily, but it's not really there for watching shows.
If you have a lot of DVDs I reccommend ripping them onto a computer or home media server. Then you can stream them to most set-top boxes over your home network, and not have to worry about losing, or scratching those disks. I hear very good things about Plex video library software, and it can run on the more powerful models of Synology DiskStation. The Synology Video Station software is very decent software for managing and viewing your stored movies and TV shows too.
So, this is my take on TV technology. Use a laptop (or tablet) and some combination of video streaming services that you like. Abandon optical media (DVD and BluRay) as much as possible. And if you want to use a big TV in your home, go look at the guide linked at the top of the page. Sorry I'm not more help.
