Technology Predictions for 2006?

OffTheLip writes "As 2006 fast approaches it's time for some to gaze into the crystal ball of technology and predict what will be hot, what will make a difference in our lives or make someone rich and famous. The Mercury News takes a shot at predicting the coming year of technology. No great revelations but it nice to see clean technologies make the list. The list is light on pure technology and big on trends. Perhaps killer apps are not as important as they once were thought to be." What would Slashdot users put in their top 10?

Howard Stern is definitely drawing new customers to Sirius radio. I work at Radioshack and my entire district is sold out of all Sirius recievers and we have waiting lists. 75% of the customers say they are buying because they wanted Howard Stern.

where I come from PAL has a resolution of 720x576, while our neighbors in NTSC land can see 720x480

If only it were that clean.

Horizontally speaking, NTSC encodes various components as signal brightness and two color information streams of differing bandwidth. The brightness can change at a rate that is approximately equivalant of 700-ish brightness changes per scan line, with the other 20 or so appearing in the overscan area which is typically hidden by the way television tubes are mounted; your milage may vary a little if you have an LCD, but then again, it may not. Color changes are a function of combining the brightness change with the two color components. These components can change at an average rate of 100 color changes per complete line, however, because one component is slower than the other, not all color changes can be reproduced at that rate. Notice that I described this as a rate; that's because television, real television, is a pure analog signal and although the rate that the brightness and the colors colors can change is limited, the position that a brightnes or color change can occur at is only limied by how recently one already did... if colors haven't changed within 1/100th of a line, then you can have a color change fairly precisely located... at the cost of not having another for a 1/100th. Similarly, a brightness change (or a green amplitude change... some of you will see why when I describe the math, for the rest, it's magic, trust me) can occur at a rate of about 700, but they can start anywhere and so the precision with which either a brightness change or a color change can be located on a scan line is in effect infinite with an analog system. When displayed on a typical color television tube, most of this capability is lost because the display beam only has a finite number of RGB phospher triads it can illuminate, and the analog detail is re-sampled by the "jail-bars" of the phosphor dots or slots. However, this is still true of a black and white set, which has a continuous display surface. Again roughly, greens change the fastest, reds the next fastest, and blues the slowest of all. These color change ratios (to one another) were designed to mimic the ratios exhibited by your eye's sensitivity to similar changes. Unfortunately, while the idea is sound as far as it goes, your eye's ability to deal with those changes, ratios aside, is so much higher than the change rate video provides, that I would argue that the designers kind of screwed the pooch in this area, but that's a different discussion. :)

The math is done like this, again more or less, using the R, G and B (red, green and blue) color components: Brightness = .59 times G plus .3 times R plus .11 times B. That gets you luma, a black and white signal that offers compatability with how the older BW television sets worked. This is also called "Y". The first color component is simply (R-Y), although as I mentioned above, it is bandwidth-limited so that the color changes are encoded in a broad, blurry way. The third component is (B-Y) and it is bandwidth-limited even further... slower and blurrier. The color image is re-created at the display this way: R = (R-Y) + Y, B = (B-Y) + Y, and G = Y - (R + B), keeping in mind the RGB .59, .3 and .11 scaling factors.

As far as vertical resolution goes, this is a bit easier to understand. For both systems (PAL and NTSC) the display is created in two passes. One the first pass, half the lines are painted. On the second pass, the other lines are painted in between the originals. Next time, the others again and so forth. These are referred to as the odd and even fields of a frame. A frame is considered to be definitive of how many lines you see, and it adds up to 400+ (odd=200, even=200) for NTSC, PAL a little more, with the remaining scan lines again typically hidden as a consequ
