[linux-dvb] 16:9 first solution

[rolf@max.lui.uni-tuebingen.de]

Hi All! especialy Emil!

The DVB Card can be used to view 16:9 Movies,
with the best possible Resolution on a 16:9 TV!

This can be done by changing the Aspect Ratio
in the mpeg2 file.

by viewing into a mpeg2 datafile one will notice repeating
byte sequences starting like (Hex)

00 00 01 b3 2d 02 40 

The next Byte contains the Aspect Ratio and the Framerate.

For example:

33 (Meaning 16:9 and 25 fps)

Change this to:

23 (Meaning 4:3 and 25 fps)

And you get the full not downscaled Resolution of
for example 704x576 Pixels. 

All thats left to do is turning the 16:9 TV Set
into 16:9 Full Res Mode. Meaning extending 4:3
to fully fit to the 16:9 Screen. Horizontal Zoom.

The difference in Quality is quite impressing.(especialy DVDs)

For now i ll try to write a little Program that can do
the Translation on the fly. since one has to do that
very often. Something that works like

cat bla.vob |sixteen2nine >/dev/video

This will take some time since im a rather unskilled 
 Programmer. But ill try my best and will keep you
uptodate.

Greetings
         Rolf
