My understanding is this:
Freeview SD is 576i (not 576p). (Specifically, it is: 576i50; see below.)
Freeview HD is either 1080i50 (i50 == interlaced at 50 fields per second),
or 1080p25 (p25 == progressive at 25 frames per second).
A frame consists of two fields.
A field is either the odd-numbered scan lines, or the even-numbered scan lines.
In the UK, the HD datastream can oscillate rapidly between i50 and p25, which can give judder when panning horizontally (depends on settings). I only recently found the settings that cured this (on MediaPortal).
