  • BBC HD quietly begins broadcasting in 1080p, but not all Sony HDTVs can handle it

    We'd pretty much given up waiting for broadcast 1080p, since other than some video on-demand services you'll generally need to stick to Blu-ray to tick that box, but around the end of March BBC HD changed all that. It's taking advantage of a part of the Freeview HD spec that allows the broadcaster to dynamically select between 1080p / 25fps and 1080i / 25fps transmission and the boxes are mandated to be able to output 1080p / 50fps. The reasoning for the decision is to provide better picture quality on material that was shot that way, unfortunately it's coming to light now because some HDTVs are having trouble handling the switch and causing an audio dropout when the format shifts, as mentioned by UK buyers guide What Hi-Fi. As if Sony didn't have enough to deal with, the overwhelming majority of complaints appear to center around its TVs and the company has promised more information in the next 7 - 10 days about a fix that will take care of the problem.

  • PSP-3000 put under microscope, interlacing issue exposed

    You know those complaints about the ugly, old-school looking interlacing lines that many (ourselves included) have reported seeing on the new PSP-3000? The specific issue has been uncovered -- but not by Sony. A group of concerned French gamers with a 40x microscope think it all comes down to that most mellow of colors: blue. LCDs are comprised of RGB pixels that, combined, form all the rainbow of hues in between. As you can see in the picture above, the PSP-2000's LCD (left) used pixels in a vertical orientation, and the blue pixels were fairly light in color. On the PSP-3000 (right), the pixels are now arranged horizontally, and the blue ones are far darker than before. The dark horizontal lines result in the heinous interlacing, an effect that any Command & Conquer player will tell you wasn't even cool in the 90's. Sony's already called this a "feature" and not a flaw, so if you absolutely must buy a PSP this holiday season the folks at Logic-Sunrise who took the above pics recommend you buy an older 2000-series -- while you still can.[Thanks Pierce]
