Blu-RayOFF: не все плейеры одинаково полезны

We began by connecting both the BD-P1000 and the Elite BDP-HD1 to a pair of side-by-side, matching 50-inch plasma displays - Pioneer's new Pro-FHD1 Elite plasma, that's fully 1080p compatible. We connected the players to the monitors first via HDMI, selected full 1080p resolution (which both the Samsung and the Pioneer are capable of delivering), and used an identical test disc in each player to play back MPEG-2 encoded footage of Disney's Chicken Little (we photographed a nearly identical setup playing the same disc at CES in January). I had told Chris that my first impression of the Samsung player was that the video image lacked some of the detail I had expected to see, and that it wasn't fully delivering all of the color and contrast information encoded on the disc either. He had also experienced this on another production BD-P1000 that they in the office, by the way. Sure enough, that was the first thing we both noticed. Colors and contrast (particularly color) from the BD-P1000 just seemed more subdued compared to the same image delivered by the BDP-HD1, and some of the fine detail in the image was also missing. The difference was rather dramatic. It's almost as if some kind of high-frequency filter is being applied, or as if the Samsung player is doing some kind of extra signal conversion before it sends the signal out via the HDMI connection. It's not the connection itself, because as Chris confirmed, both players use the same HDMI hardware and chipset. So it has to do with the way the Samsung player is processing the signal. By the way, to confirm that what we were seeing was really an issue with the Samsung player, and not the plasma displays, we swapped the displays connected to each player and sure enough, the video quality issues migrated to the new display.

To test something that I suspected might be the case based on my experiences with the Samsung player, we next connected the BD-P1000 to the display via the component output, and selected 1080i resolution. As I suspected, and to Chris' surprise, all of the problems with the video signal just disappeared. Suddenly, the video being displayed by the Samsung was MUCH closer in quality to the 1080p HDMI output of the Pioneer. Colors and contrast were VERY close to identical - colors just popped off the screen - and fine image detail was significantly improved on the Samsung side (although still not quite as good as the Pioneer - the difference was about what you would reasonably expect between analog component and digital HDMI connection, along with an interlaced image versus progressive scan). The upshot is, if you own a Samsung BD-P1000 and you want to experience the best possible image quality - quality that closely approaches the full potential of the video signal encoded on the disc - you NEED to be viewing via the component output. Now, that's troubling given that protected digital HDMI is what everyone in the industry is encouraging people to use. Yes... the Samsung is capable of delivering full-resolution 1080i video to your display via component. Like all Blu-ray and HD-DVD players, the player must be able to read the Image Constraint Token flag on the software if the studios choose to turn it on (and thus disallow full-resolution analog playback). However, the good news so far is that neither Sony or Lionsgate has chosen to exercise this option yet (for that matter, neither have any of the HD-DVD supporting studios either).

By the way, the scaling problem I was having between the Samsung and my Panasonic LCD projector via HDMI at 1080i resolution wasn't happening with the Pioneer plasma. It also isn't happening at any resolution via the component outputs, so it's definitely something endemic to the way the Samsung and my projector handshake via the HDMI connection. I'm hearing a few reports from other Panasonic projector owners who are having the same problem, so it's not just confined to my specific model of projector.

к сведению: я сам тестировал самсунговский плейер, причем никаких проблем из описанных выше я не видел.
вывод: торопицца с покупкой не надо
