HDTV in the UK

[BarMoo]

Since we both went OT ages ago - i'll elaborate. Probably doesn't help with me flitting between DVB-S and DVB-T

"12 for the price of one" - I thought - referred to re-use of existing bandwidth via compression, in fact impossible at that ratio. So, what did it actually mean?.

Statistical multiplexing has allowed operators on both DVB-T and DVB-S platforms to maximise bandwidth use. See my attached pic for an extreme pisstake example courtesy of Viacom (not MTV )

Yes, there were many factors in On Digital's collapse, but poor cofdm performance was certainly a major one (they didn't get enough revenue - partly because - not enough people could get the signal!)..

I wouldn't say partly, I would say completely because OnDigital ran their DVB-T transmitters on paraffinised hot-air. Reduce signal strength and its not going to travel/penetrate. Todays figures still show that DTT signals typically reach half the distance as their analogue signal friends (e.g. figures after so-called Freeview signal 'boost').

Compare: Crystal Palace (London): MUX D / 16-QAM / 20kW / 18 services
Compare: Alexanderplatz (Berlin): MUX 44 / 16-QAM / 120kW / 4 services

Though, to be fair you have 6 MUX's and we have 8 - and we've 'switched over'.

Mark.

It must be said that the picture quality is far superior, i was surprised how stark the difference is with SD. However, I shall stick with SD for now - Sky ALWAYS reduce subs for new services to the levels of the previous services (give and take sub rises) eventually.

I don't agree that OTA picture quality is 'far superior'. I've seen several demos and I don't think there's much (if anything) between HD and SD on good quality CRT TV such as Philips with Pixel Plus.

Another contributing factor to the demise of Ondigital was the poor choice of encryption. Quite easily cracked as is a certain channel on Freeview.

You know, very few people will accept that for DVB in its SD form, the best picture will only ever be achieved via DVB-S, an RGB SCART and a decent CRT TV without 100Hz processing (or any other processing for that matter). In fact, its about the only time I might have to say having a SONY on the end of a digibox is about the best you will ever get.

I know its personal thing, but I won't listen to anyone challenge a Trinitron !

I voted no chance because i don't want to put any more money into this :-) The current setup and quality is more than enough for me.

Slighty OT - but has anyone purchased a Blur-ray DVD yet?

While the disc is the same size as a bog-standard DVD - I've heard that the packaging box is a totally different size and probably won't fit into that nice DVD cabinet you bought a couple of months back.

Moo.
