Reflections from a Swede in Norway.

Here you will find my small graffiti board where I write about things I come to think about.

In my blog, I write about the general unfairness of life, about spam mail, vintage computers, board games, Norwegians, current and not-so-current affairs, technology and whatever else occurs to me — in other words, a glorious mess. All opinion expressed here are of course my own, and all similarities with any living people is of course intentional.

Bitwise improvement

Published: Friday 2004-09-24.

Okay, I couldn’t resist, so I ordered a package of channels for my cable tv and was thusly provided with a decoder for digital tv. Unfortunately the digital cable tv suffers from the same problem as satellite and terrestrial digital tv does, the channels are heavily compressed so that they can squeeze more channels into the network.

Indeed you do get less noise in the picture than in the analogue transmissions, a one-coloured area is really one colour and steady, but on several of the channels one can clearly see MPEG artefacts, that is, indications of a heavy compression, so that thing about getting perfect picture quality is something one can only dream about, it is just a slogan the marketing people has raved up.

But there is one advantage to digital tv compared to the classical European PAL transmissions, and that is that it can broadcast in other formats than 4:3. Since I have a wide-screen television it is nice to be able to use all of the screen area without having to zoom into the picture and getting a lower resolution as with the classical analogue transmissions. There are a couple of ideas on how to send 16:9 over normal PAL transmissions as well, but they are all just gross hacks.

Well, anyway, now I can watch ZTv, so now I just wait for the programming to start!
