I love my digital video recorder. I shall never watch another ad.
Can you set that up so that it omits all adverts then? And does it
work 100% (in the face of all the efforts of the advertisers?) How
does it work?
I press the FF button, and with practice can go *very* fast and not
overshoot (well at least not too often).
it would be lovely to have it eat the ads automagically, but I doubt
we'll see commercial products that do that anytime soon.
**I looked at doing just that a dozen or so years back. Back then, TV
stations used to send a 200mS of black level, before and after ads.
Trouble was, the system was not infallible, since some programmes go
to black.
you could almost do it looking solely at volume levels. ads are *always*
louder, some channels more so than others. Still, 8x or 20x FF works
pretty well, and requires little or no effort on my part.

Elektor published a design a few years ago that identified the
station/broadcaster watermark in the video stream and output start/pause
codes via IR to the recorder at the appropriate time. The recorder IR
codes were entered using a learning mode like the universal remotes.

Never built it but it seemed a sound concept.

it's just a software problem as others have said there's a watermark
that can be used, all that needs to be done is detect it and stop
recording when it disappears and start a few seconds before it
reappears, as it typically turns up late.
one way would be to buffer a few seconds worth in RAMOn Aug 22, 6:51 pm, Jasen Betts <ja...@xnet.co.nz> wrote:

MythTV <http://www.mythtv.org/> uses the logo and a couple of other
clues. It is conservative so it does miss some advertisements but mine
has never lost any program content. Like any other PVR it always
"records" a program so that it, and you, can skip backwards and
forwards. My computer is not powerful enough to remove advertisements
in real time so I have to wait about the same time as the length of
the program before I can watch the advertisement-free version.
It is not a commercial program and it is totally free but not the
faint hearted. You can build a MythTV PVR for a little less than a
similar consumer product. Commercial programs do what the content
providers want them to which resulted in some Microsoft Vista users
missing not just one program but several days recording

Hah - from a QSC schematic, 2SA1943 and 2SC5200 (widely used) are good for
30 MHz and plenty of volts and amps.
