The Simpsons; The Standard American Family Now in HD

Although the Simpsons’ adventures are far from typical of everyone’s daily lives, the larger image around it certainly is. Somehow, the Simpsons have always represented what the average American family was and, more particularily, what it should be.

Recently, the Simpsons have began broadcasting in HD, along with a brand new opening sequence in all its high definition glory. Although this is a natural evolution, the new version of the Simpsons has a particularily eerie presence of HDTVs in it.

And there is a reason for that. In preperation for the United States’s pushed back digital transition, and in migration to a more sophisticated standard–HDTV–along with the poor economy, there’s nothing like a classic cartoon nobody doesn’t know about to push HDTVs into households and make people spend.

From Bart’s writing on the Chalkboard and the flat panel HDTV in the Simpsons’ living room, the message is pretty clear, having a flat-panel HDTV in your living room is the new standard.

I see crappy colors; What are you missing without an IPS?

What’s an IPS? It’s another kind of LCD than the one you probably have as your computer monitor or laptop screen.

When LCD technology was first being marketed, TN technology won over IPS and other technologies as the perfect choice because it solved two lingering issues: affordability and speed. Yes, those infamous 2 ms LCD that you see everywhere are the TN displays.

However, TN has two big flaws. The first is the most obvious to any direct comparison, the view angles. Moving your head just slightly will result in drastic picture changes when looking at a TN display. Even worse, looking from under gives unpleasent flashy blacks and looking from the side makes the whole screen reflective. This isn’t a very accurate description of the effect, but if you have a Nintendo DS, you can experience it right now by playing a game like Brain Age, where the DS is turned on the side.

Why are those swivel-capable LCD displays so costy, because they handle view angles and different point of views marvelously; they’re IPS LCDs.

Secondly, TN displays are not true color. Yup, TN technology can only represent 6 bit per channel, or, 18 bit color. You may think that doesn’t make much difference with 24 bit, but think again, it’s exponential.

18 bit color means 262,144 colors.
24 bit color means 16,777,216 colors.

That’s quite the hopping difference. On a TN display, I could give you 64 values or Red, Green and Blue instead of 256 and you wouldn’t even notice the difference. That’s how important an IPS screen is, especially if you’re working in graphics.

Nevertheless, IPS LCDs are pricy, and for a tad lesser view angles, S-PVA panels can get you full color (not PVA). If you can afford one, and the research to actually find one amongst displays sold by Dell, it really is ideal.

If you’re buying a Mac, you’ll be happy to know that every external display, 17 inch MacBooks and 24 inch iMacs include an IPS display. However, the cheaper models don’t.

Oh, and by the way, if you’re buying a notebook PC, you’re out of luck, virtually none come with IPS displays. This is why color correction is not done on a laptop. Also, poor you if you bought the brand new 15 inch MacBook, yes, earlier iterations, like all of Apple’s line of computers, had IPS displays.

PS. If you know other laptops or affordable displays with IPS technology inside, drop a comment!

Anime: Changing Artist Halfway

I was listening to The Third and uppon listening to 13, it seemed to me the drawings were awkward, making the characters look fat. So, I did a comparison with past and future episodes, and to my delight, it’s the only episode that’s this way.

The change is stunning. It really is another artist.
Let’s take a look.


The second image is the original of course; I’ll keep it this way from now on. But, hey, if that isn’t obvious. Just look at the nose!


Although closer to the original, it’s far from it. The nose, the face’s roundness, the hair detail. Everything!


Honoka and Millie. This one’s most notable aspect is probably the lack of hair detail on Millie.


And for the final, fat face!

Really, I hope the artist of the filler never makes Anime or Manga. May you stay as a good in-between-animation frame artist.

DSD Applied to Video – Beyond the Pixel

DSD is somewhat Ironic (What is DSD) because its process is quite literaly immitating the analog signal. But in audio, much to the contrary of video and imaging, this is the best thing to do.

In imaging however, the saying goes digital is better since it can describe every pixel in a lossless matter, which is good because this is how monitors work.

However, digital imaging is stuck to pixels. You can’t get more than what the pixel gives you with a pixel. With traditional films, you could rescan a film tape and get a greater amount of detail in it. A very direct impact of that is that traditional film cameras (the very expensive ones) are expected to be around 120 Mega Pixels, in theory, much higher than today’s best Digital SLRs.

While this theory is largely eliminated by the fact digital imaging never loses quality because you can’t degrade a bit of numeric information, it’s either a 1 or 0 and that’s where it ends, I came to the conclusion DSD could be applied to imaging, digitally, much the same way as it was for audio.

Think of it, the technology already exists. NTSC is transported over analog as a modulated signal on a 4.2 MHz bandwidth. Since this signal is essentially composed of waveforms, it could be digitally encoded in the same way as DSD: on a 1 bit high frequency stream using algorithms to describe its content. This could essentially describe visual content in a way that goes beyond pixels because it’s mathematically scalable functions stringed together.

But, this is a very “in the air” theory. Fixed images cannot be described on a lenght of time, so an image would have to be a peice of video. Editing such data digitally could prove immensily complex, the very reason why the best SACD discs are mastered from a PCM-based recording instead of a DSD stream. And as I am not scientific, there is probably a dozen of other holes in my theory, but hey, we can dream and you have to admit the idea is technically cool.
