|About HD High
Definition Video (H.264/MPEG-4 AVC 720p)
High Definition Video (HDV) is a digital video format
720p is the shorthand name for a category of
HDTV video modes. The number 720
stands for the 720 horizontal scan lines of
display resolution (also known as
720 pixels of vertical resolution), while the letter p stands
progressive scan or non-interlaced.
There are 50p (frames per second) (progressive format mit 50
full pictures per second).
Progressive scanning reduces the need to prevent flicker by
filtering out fine details, so sharpness is much closer to
1080i than the number of scan lines
720p is always displayed as 1280×720 resolution in 16:9 format.
The compression rate of our HD-Videos was created by the currently
most efficient MPEG4/AVC
(H.264)-codec and the bitrate selected is 4 Mbit/s.
Size of the HD files
Our HD-video file size is approx. 3 to 4 times larger than the file
size of its comparable and already familiar WMV9 file. Consequently
the downloads of HD files will be taking approx. 3 to 4 times more
time than the downloads of the WMV9 files of the same movies will
Compare HD and WMV9 resolution
The pictures displayed below are original frames from one of our
videos. The cropped part (red) will be the picture we're going to
||WMV9- frames are 4 times
smaller than HD frames are. Therefore we had to zoom the
picture at 200% for making it comparable.

of the HD-frame is certainly much better.

Watching our HD-videos on your Computer
being able watching our HD videos on your computer, your operating
system and/or your software ought to have the MPEG4 AVC/H.264 decoder.
Therefore you'll need software! We recommend downloading the VideoLAN - VLC Media Player™.
This media player software includes the necessary MPEG4 AVC/H.264
decoder. This is free software and it's pretty good media player
software, too. If you don't have it but if you need it, you should
download the VideoLAN™ Player
Power DVD™ 7 + Ultra, Nero Showtime™, Windows Media Player™ 12
(with Windows7™ only!) and QuickTime™ 7 is all software which can play
our HD videos on a computer screen correctly.
HD-videos on your TV
now there's already available some good hardware that can correctly
play H.264/MPEG-4 AVC codec on a TV. Particularly hardware with a Sigma Chip™ is pretty good and useful.
Your TV should perform a 720p resolution minimum. (in Europe such
TVs were/are labelled as "HD ready™").
you'll need a little bit more than just a good TV for playing any
digital HD videos on your TV. We're using the Western Digital WD TV™ HD Media Player
and it currently costs less than $ 100 only (price seen e.g. at amazon.com™).
Play content from most popular
USB drives, store your HD DWW-Movies downloads or your
Tribgirls HD downloads to the USB drive and then simply connect the
USB drive with your WDTV and watch all your media files on your TV.
It's blindingly easy! Of course, by using this device, you can watch
WMV9 files on your TV, too. However, although your familiar WMV9
files will play nicely, too, those WMV9 files will never give you
the excitement of real HD quality!
Here's a list of hardware we did test for you for playing HD videos
on a TV (no responsibility is taken for the correctness of this
