Is the integral Freeview on my 32 inch Full HD TV HD or Not
Simple answer. No. But please read on . . .
Full HD Freeview, i.e 1080p does not exist. The four HD channels currently available on Freeview all transmit at 720p resolution. There is insufficient bandwidth in the TV transmission range for the HD channels to transmit at 1080p. It could be done, but it would be at the expense of other channels.
Your TV, however, is Full HD, as indicated by the 1080p in the specifications. This means it can display a full HD picture from a device which outputs at 1080p resolution. Devices which generally output at 1080p resolution include Blu-ray DVD players, games systems and PCs.
When viewing a Freeview HD channel, your TV will display the picture in 1080i (interlace) resolution. This is not true/full HD. The transmitted picture comprises of 720 horizontal lines and the software inside the TV is creating the additional 360 lines and interlacing them between the 720 lines from the original transmission in order to create a 1080 line picture which fills the entire screen.This process is commonly known as 'upscaling' and can cause deterioration in the overall picture quality, most noticably on poor quality, cheap TVs.
Hope that explains it for you sufficiently!
