Aspect Ratio Setting; Recommended Settings - Uniden HD8000UPVR Owner's Manual

Aspect Ratio Setting

Digital TV broadcasts carry a mixture of widescreen (16:9) and standard (4:3) format
programmes.
Under new guidelines; all new TV sets will have an ex-factory default setting which
makes the set follow the broadcaster's transmitted picture format codes. The
Active Format Descriptor (AFD) code will allow some view preferences to operate
automatically, but only those which the broadcaster has catered for in making the
programme. For example, it will allow a viewer to fill the screen of a 4:3 TV set
with the centre portion of a widescreen picture, but only for programmes 'shot and
protected' to allow for this, so that cutting off the edges won't lose important action in
the scene.

Recommended Settings

The HD8000UPVR offers the following options through the A.Ratio (aspect ratio)
button on the remote control:
16:9
AFD 16:9 Wide (factory default)
4:3 Letter Box
4:3 Centre Cut
AFD 4:3 Letter Box
AFD 4:3 Centre Cut
The view option AFD 4:3 Letter Box is interpreted as a best compromise for the
various formats.
Recognising that viewers may not always be satisfied with the broadcaster's
recommended display format or choice of formats, TV sets may also have a 'viewer
preference' setting, in which the viewer's wishes override that of the broadcaster, the
viewer will have to select these other modes deliberately.
