In a DVB system, the tuner doesn't tune into a single channel - it tunes to a multiplex (or a 'bouquet' as the spec calls them) that can carry a number of channels. A multiplex usually occupies the same air space (analogue bandwidth) that a single analogue TV channel used to. Usually a single terrestrial multiplex carries 3-6 channels or programmes (satellite and cable systems can carry even more). The tuner then outputs a bit stream that contains all the channels in that particular multiplex, and the rest of the system can pick any one or more of them for further processing. The digital bandwidth in a multiplex is fixed, though - the more channels you pack into one, the less bandwidth (and less quality) is available for a single programme.

(this is why terrestrial HD in Europe has shifted into using DVB-T2 instead of DVB-T, which was used to carry SD - it is more efficient, allowing more digital bandwidth = channels to be encoded into the same analogue bandwidth, which is always in short supply)

So in theory you could record all the channels in that multiplex at the same time, and even view one of them live at the same time. But as soon as one of the desired programmes is in another multiplex, you need another tuner. Usually twin-tuner systems allow you to record two programmes and watch a third (provided it resides in the same multiplex with one of the programmes being recorded), but you could just as well record all the channels in those multiplexes. I believe the limitation is somewhat artificial and mostly due to user interface issues, it would be difficult to explain for a non-technical user why he sometimes can record more channels than at some other time.

It's not even hard work, I use a Linux based HDR that can easily record six channels at the same time with a single USB DVB stick - running on an ancient 600 MHz Celeron and a regular old IDE hard drive.

just received mine

i'm still a newbie when it comes to bang and olufsen.
i'll unbox it later when my dad gets home, also i'm a gamer so if this thing sucks with games then i need to get another one also :S
also great review KMA thumbs up, cause of the review i had a harder time waiting for it :P

regards

Wow - thanks for that ! I enjoy these lectures ... they expand my understanding ... and sometimes they depress me at how everything seems so complex these days ... compared to the steel needle phonograph and a bunch of 12" shellac records (not LPs!) that was my very first music purchase for I think one pound sterling at a jumble sale shop ... or it may have been ten shillings, after all a pound took the savings of many newspaper rounds to achieve 🙂

Congrats there nick, what size did you get it in and didn't you want to get it installed by b&0??

 thanks 46 inch this will be for the bedroom, got it with the motorized wall bracket.
not yet i will only test it now and put it back into the box again i'm just already buying things for my new house, i'll make some more pictures in abit.

Wow for your bedroom, very lucky indeed i look forward to more pictures and of course your opinion too. I'm a gamer aswell so i look forward to hearing how it handles when set to the actual game mode preset.

Once again congrats.

Congrats on your purchase. I as well would really like to hear how it handles gaming, particularly FPS games

Does it work well , Chris ?
