Freeview is the free terrestrial digital television service in the UK. 2010 is the year that it will introduce HD broadcasts.
Most UK televisions sold since 2008 have a freeview tuner built in but it is only televisions sold from 2010 onwards that are likely to have an HD freeview tuner built in. The manual for the television will tell you whether it has an HD tuner. If it doesn't, it is still possible to get HD broadcasts on Freeview by purchasing an HD set top box.
you need a HDMI cable and 1080P media like a Blue ray disc and a HDTV with 10080P capabilities before you will receive full 1080P. For example most HD TV programing is only 720P and will not be in full 1080P on a 1080P HDTV and a TV show in 480i standard will be in 480i on a 1080P HDTV

Put up your own Antenna if you have a HDTV or subscribe to a Satellite service.
HDTV is a new format for displaying a TV picture. It has higher resolution and clarity than the old NTSC format. Most stations that are broadcasting digital signals are now using 4 channels for every 1 they had before. They are reserving some channels for HDTV format and some channels for NTSC format. An HDTV will display the HDTV format and probably the NTSC format as well. An HDTV monitor can display the same picture, but probably lacks a tuner to actually receive the television signals. You need to plug something into it like a computer, a DVD player, or a tuner. If that thing sends out an HDTV signal then you can see it on the monitor.
The TV with a large screen came before HDTV ever came out. I have an Old Projection TV that is over 25 years old that is kept in the basement. Most new TVs are made with HDTV, but they do not need HD programming and can receive standard 480i shows on a HDTV.
No you can connect the PS3 to a non HDTV, but it will not receive HD only standard reception
