|My reference to a DVR was what I thought was the term used in the USA for the set top box (STB) device supplied by the typical TV channel supplier. In Canada here the STB is called a PVR (personal video recorder) if it can record TV programs as well as play live TV channels (that are usually coming in by some non-over-the-air wire source such as cable company coaxial or internet). |
The STB and TV channel source I use is similar to what is available with AT&T’s U-verse system. My supplier TELUS might have licensed the technology from AT&T, not sure. The TV channels are transmitted over the internet. With a 50mbit connection 4K is possible. There are only about three 4K channels available here right now, if I sign up. I just have an older 1080P PVR but lots of people have upgraded to a 4K PVR version, it can play back 4K. My supplier TELUS is always trying to get me to upgrade to their fibre connection (fibre cable is in my garage ready to be activated for very little extra cost). I have a couple of 4K TVs but have not yet upgraded to fibre because I know there is not much 4K video available, and I don’t really need more internet speed. Currently have a total of 25 mbit and that is OK for 2 1080P TV channels plus a couple of people websurfing. But the trend toward 4K is clear so I might as well get ready and do some upgrades.
