Since I am firmly committed to the Blu-ray format in my theater, it was only a matter of time before I felt the overwhelming need to add the format to my living room AV system. With more and more TV shows being released on hi-def disc I couldn’t quite bring myself to buy my favorites on DVD when they are available on Blu-ray. To that end, I recently installed Panasonic’s latest entry, the DMP-BD50.
The BD50 is Panasonic’s third generation player and its most feature-laden to date. In addition to all the excellent video playback features carried over from the BD30 it supports full PCM and 5.1 analog decoding of ALL lossless sound formats. This is the main reason I waited for this player rather than buying the less-expensive BD30 for my living room. The BD30 only supports lossless formats as bitstreams. You will need a decoding receiver like the Onkyo SR-805 to fully enjoy the improved sound Blu-ray has to offer. The BD50 works nicely with my Denon 3806 by converting all sound formats to LPCM which the receiver accepts through its HDMI 1.1 inputs.
Aside from the improved sound support, the BD50 appears identical to the BD30. Though I have not compared them side-by-side on the same display, I can see no difference in image quality between the two. I believe both players have the same video sections. Menus and setup are pretty much the same. 24fps and DVD upconversion to 1080p are supported and you can force both resolution and scan rate if your display doesn’t play nice. As I am still using an older 720p Samsung TV, I set the BD50 to 720p and 60hz. Sound setup was a bit different. In the Audio menu, you can specify the type of digital output independently for Dolby and DTS formats. These settings will hold for Blu-ray and DVD playback. This means if you’ve specified PCM for Dolby and DTS formats, your receiver will say “PCM” or “Multi Channel” whether you play a Blu-ray or a standard DVD. For those of you wondering, I can’t hear any difference between audio that’s bitstreamed or decoded to PCM. I certainly CAN hear a difference between compressed (Dolby Digital & DTS) audio and uncompressed audio (Dolby TrueHD & DTS-Master Audio). Detail and clarity are much better and the dynamic range of even an average soundtrack is larger than the best mixes on DVD. I don’t believe you have to have a killer system to enjoy the benefits of lossless sound. My living room is far from ideal and I don’t have expensive gear. I do know that the soundfield is larger, the sense of surround is greater and detail is improved. I know there are other media formats vying for your entertainment dollars but Blu-ray is the only one to offer such a huge improvement in audio quality.
As I stated, there seems to be no difference in image quality between the BD30 and the BD50. DVD upconversion isn’t too bad. It’s not the equal of a high-end processing solution like Anchor Bay or HQV but I think it does a better job than the cheap upconverting players I’ve encountered. It certainly beats the video processing in my Samsung DLP. I noticed a few combing artifacts and occasional jaggies but images were noise-free and color fidelity was excellent. There was no added edge enhancement and dynamic range was superb. Though this player did not ace the HQV test disc, I still would consider it an excellent DVD player. The next step up would be Oppo’s $400 983 or Denon’s $850 2930. The BD50 will play standard audio CDs but not DVD-Audio or SACD. It will play all burned media provided it has been finalized. It also accepts SD memory cards like the BD30 for viewing of photos and home videos.
The BD50 is one of the first Profile 2.0 players on the market. It has the required Ethernet connection on the back panel. It does not however have sufficient internal memory. For this, you must install an SD card. I did not test the BD-Live features of this player but I did install a memory card just in case. They’re so cheap now; you might just have one lying around the house!
Obviously, I am quite happy with this new player. At $599 it’s not cheap but the bleeding edge never is. I wasn’t sure I would be as thrilled with Blu-ray on a 50-inch 720p display as I am in the theater with its 92-inch screen but I am. The image quality is simply wonderful and the audio is equally amazing. There’s just nothing like an artifact-free color-saturated picture. It’s much more difficult to achieve that from Standard DVD. Even an average-quality Blu-ray is superior to the best DVD transfers. I’m all about removing video processing from the signal path whenever possible. Now we have a format that allows this and I think we need to embrace it. Of course there will be something better in the future but when is that not the case? Blu-ray is the best video and audio format going right now and is likely to be for the next few years. Don’t miss out on the opportunity to get the most out of your display right now!
Thanks for reading and enjoy the view!

Panasonic AE1000U LCD Projector Calibration
The 1080p projector market is white-hot these days with several superb units priced at under $3000. Even one year ago, this was almost unheard of. Epson, Sanyo, Mitsubishi and the subject of today's article, Panasonic, all make models. The model I calibrated is the AE1000U. It has been recently replaced by the AE2000U. This unit uses a new LCD panel set and is slightly brighter. In fact, the 2000 uses the same panels as the new Epson HC1080UB. But I digress: The AE1000U has every possible calibration control available in the user menu. You have complete control over color primaries and secondaries, grayscale, and a neat 3-point gamma control. There is also a waveform monitor that makes setting black and white levels very easy. You can have the waveform on the screen while you navigate through the various menus and make your adjustments.
The AE1000U has 2 HDMI inputs as well as component, s-video and composite inputs. There is also an RS-232 port for control systems. There is no IR hookup but the receiver on the front of the unit is very sensitive. I had no trouble bouncing the remote off the screen to control the projector. My client had the projector ceiling mounted with about a 12-foot throw to a 100-inch Da-Lite fixed-frame screen. I measured the screen's gain at 1.1
First up was geometry. It's important to have the image perfectly positioned without visible distortion. There are horizontal and vertical lens shift controls for this purpose. There is also a 2x zoom for lots of flexibility in sizing and placement. Vertical shift range is one-half screen height above or below the screen. Using the extremes of the vertical shift will limit the horizontal shift. This is not an issue if you place the projector's center-mounted lens within a few inches of screen center. Once image geometry was set, the calibration was pretty much the same as a direct-view display. Black and white levels were set with pluge patterns and checked with the waveform monitor. I measured gamma before grayscale calibration and came up with a disappointing 1.71. After turning off the dynamic iris, it improved to 2.0. I was able to get it to 2.2 with the 3-point gamma control, which has sliders for high, mid and low. I only needed to lower the low control to get a perfect curve. Given this result, I left the iris off permanently.
Grayscale was no problem with the complete set of RGB gains and cuts available. Color decoding allows several approaches. You can adjust the primaries with the color management system. This involves displaying a pattern, a 75% color window works for me; then setting a target to adjust. You can tweak the color, tint and brightness of the primaries (or any other color for that matter) this way. After some very small adjustments to the color profile, I had a perfectly aligned decoder and primaries and secondaries were spot-on. At this point, I should talk about the different picture modes. The 2 to be concerned with are Cinema 1 and Color 1. Cinema 1 is claimed to be "Hollywood style colors" in the manual. It places a filter in the light path that darkens the image. It also appeared to me to introduce a slight yellow shift. Color 1 does not use the filter and is pretty much right on Rec 709, HD standard. Obviously, I left it on Color 1. The other modes are progessively less accurate.
When I was finished, I was able to save the settings in the first of the AE1000U's 8 memories. There are also 3 memories for the color profile should you wish to have multiple color gamuts available. My client's sources were an HD cable box and a Toshiba A20 HD-DVD player. The image simply leapt off the screen! Planet Earth in HD-DVD looked simply stunning. I cued up a scene where a colorfully-clad base jumper jumps into a giant cave shaft in the middle of the South American jungle. The blackness of the hole was very impressive. Any stigma LCD projectors might have had about black quality was not apparent with this model. In fact, I measured the minimum black level on a 0IRE field at .02fl. This is in the same range as any plasma I've measured. Max light output was 14fl, plenty bright for a totally dark room and a 10-foot seating distance.
I can't imagine a better projector for a small theater than this Panasonic. Other reviews I've read seem to bear this out. This projector is also the quietest I've ever worked on. You have to put your ear right up to it to hear the cooling fan. The color is very accurate, the gamma is perfect and dynamic range is very wide. At this point, I plan to add an AE2000U to my personal theater. For the same or less money than a quality 50-inch plasma TV, you can go front projection. I guess for me 92 is the new 50! Stay tuned for an article I'm preparing on my selection process for a projector and screen. There are many factors to consider when choosing the right equipment for your theater. Thanks for reading and enjoy the view!

Panasonic TH-37PX60U Plasma Calibration
Another Panasonic so soon! I guess calibrations go in phases. For awhile it was Sonys. This plasma panel is a bit older than the 700U I wrote about recently. My client has had it about a year and he was ready to unlock its full potential. This 37" TV is a nice size for those of you who have an entertainment center or AV cabinet. It fits comfortably in or on many different types of furniture. If you want a TV that doesn't draw attention to itself, this panel is an excellent choice.
Since this is a 720p (1024x768 native) display, I set my pattern generator for this resolution. I also set the cable box and upconverting DVD player in the client's system for these resolutions. It is always best to feed a display its native format whenever possible to minimize any video processing done by the set. Color primaries measured a bit oversaturated for green and red and near-perfect for blue, typical of Panasonic plasmas. Interestingly, this client had the color temp set to a warmer than D65 level. Most people are accustomed to a bluish tint on their TVs and set the color temp to normal or even cool. This is the first client I've had who actually had become accustomed to a too-warm white balance. I also noticed a fair amount of noise in the various test patterns I displayed. Unlike the 700U, the sharpness control did not help this condition.
After doing rough settings in the user menu, I entered service to adjust white balance, and black/white levels. This was tricky at first as going into service sets the TV to Vivid mode. I was fortunately able to toggle between user and service to force the TV into Cinema mode. Cinema is the only mode that allows different settings for each input. The other modes have global settings. Once I set the Cinema mode, white balance was easily adjusted to within 100k of D65. Setting black level in service also allowed me a much finer adjustment than the user menu. Exiting service, I immediately noticed a huge reduction in noise. The multi-burst patterns were now very clean and sharp. Obviously, color adjustments on this set have quite an effect on overall noise levels. As with the 700U, the noise reduction controls in user had no visible effect. The only other adjustment required was to reduce the color and tint controls a bit to compensate for the oversaturated green and red primaries. My trusty CA-6X analyzer came through once again to help me align the decoder more accurately than I could using filters. To my knowledge, no other colorimeter has this feature. It allows me to adjust the color and tint controls to align the decoder to the measured primaries rather than the reference. This is far more precise than filters which only work if the primaries are correct and you're calibrating a CRT.
As usual, my client and I checked out some content when I was finished. Discovery HD over a Cablevision feed looked stunning (I really love plasmas for HD!). The color resolution was so much better than before. My client commented that he could really see an increased color palette. There's nothing like lifting the veil of image inaccuracy and seeing what the content creator intended rather than what the television's manufacturer intended. Raiders of the Lost Ark from a Sony upconverting DVD player looked great too. This THX-certified transfer is an excellent reference for any player or display. The clarity of this DVD release is matched by few other titles. Now that we're on the eve of having all our movies in hi-def, it's still gratifying to see standard-def DVD done so well.
Just like the 700U I reported on recently, this TV is a top candidate for calibration. The client and I were very happy with the results. He considered it well worth the price and I considered it well worth my time. A properly calibrated plasma is probably the closest we can get to the venerable CRT in terms of dynamic range, contrast ratio and color saturation. I do suggest viewing plasmas in a light-controlled room. Reflections from lights and windows can be seen on the glass screen. The image is plenty bright enough however, to compete with indirect light sources. As my client had his panel in a cabinet, he solved the problem of light reflection quite nicely.
Another happy customer, thanks for reading!
