Is you digital TV recorder obsolete?

The hardware will receive any DVB-T transmission, decoding either MPEG2
or MPEG4 is up to the software, we don't have MPEG4 on DVB-T in the UK
(France do, but encrypted so software probably won't decode that, and
Sky would like to, also will be encrypted).

To receive HD in the UK, you'll need to wait until DVB-T2 is ratified
and products available and transmissions start (on a single mux).

I suppose you consider your VHS records 'all picture waves' in that case

It should be capable of recording all electrical waves modulated around
a particular frequency, the independant of **the signal shape just as
a sound recorder can record all sound waves so as to give a reasonable
reproduction on the original when played.

It's a little more complicated than that. A VHS recorder assumes the input
signal is not just any old bundle of frequencies but a particular waveform
which includes synchronising pulses which conform to a specification. These
pulses are required to synchronise the head drum to place the discontinuity
that arises from switching between heads into a part of the output video
signal where it will be inconspicuous. In other words it depends crucially
on the video signal consisting of a repetitive pattern rather than a
continuous wave.

It also depends on the colour information conforming to a particular
specification so that it can process it accordingly, but I suspect you
wouldn't want me to bore you with the details.

Sorry, Andy - it was my (evidently pathetic) attempt at sarcasm :-(

It's OK, no harm done, perhaps I ought to go back to my old policy of
killing off any thread that LTC contributes to.

I can pick up a HD USB stick for about £14 considerably cheaper
(by over £200) than what you will pay for a HD PVR (if you can find one).

What's one of them, then? Is it capable of receiving HD Terrestrial TV?
If it is, I'll rush out and get one right now....................

IYs a stick which you plug into your USB port which is capable of
receiving HDTV, looks a bit like one of theose USB memory
sticks, isf you know what they are. But if you are not computer
literate maybe it is not the thing for you.

Transmissions have alreay started old bean.

No they haven't. There were some tests of HD using the old DVB-T1, which
is probably what you vaguely recall, but those have been and gone.

When the HD tests using DVB-T1 were taking place, a few people were
able to use a USB stick to record the data stream onto hard drive, and
there were some attempts to decode that stream afterwards with a lot of
computing power and not much success.

As I said, transmissios have already started.

A transmissios? Of Channelo 9 where the forecast is always scorchio?
