Photo gallery: Panasonic DMP-B15The Panasonic DMP-BD15 is the first portable Blu-ray player, and at first it's easy to write it off as useless since much of Blu-ray's visual superiority doesn't translate on its 8.9-inch screen. But that's missing the point. If you're a home theatre buff with a growing Blu-ray collection, you might be frustrated that you can't watch those movies on a plane or even in your bedroom. The real niche of the DMP-B15 is letting you watch your high-definition discs in more locations (rather than making the immersive Blu-ray experience portable), and the DMP-B15 is well suited to the task.
It has a full suite of car accessories and an HDMI output that makes it easy to use as a stand-alone player, too. However, like many first-generation devices, the DMP-B15 has plenty of caveats: a bulky design, short 2.5-hour battery life, and less reliable playback than stand-alone players. Even more crippling is its sky-high AU$1319 list price, making it only slightly cheaper than entry-level Blu-ray-equipped laptops. Ultimately, we're on-board with the idea there's a need for a portable Blu-ray player, but — unfortunately — the DMP-B15's price and shortcomings make it difficult to recommend to all but the most well-off Blu-ray fans.
Design
Yes, it's the first portable Blu-ray player, but our first reaction after taking it out of the box was "wow, that's big". The DMP-B15 feels sizable mostly because of its built-in stand, which is actually required because of the DMP-B15's unusual design. While most portable DVD players sport a clamshell design — just open it up and start watching — the Panasonic's screen is actually upside down when you first open the unit. To get the screen right-side-up, you twist it around and lay it flat, then prop the unit up. Sitting on its stand, the DMP-B15 looks like a digital photo frame and it definitely has a sleeker look than a standard portable DVD player does, but we'd still prefer a slimmer unit with a clamshell design.

The DMP-B15's built-in LCD is surrounded by a mirror-like blue bezel, with the speakers running along the bottom. The display is 8.9 inches (measured diagonally, of course) and has a native resolution of 1024x600 pixels; that's not enough for the full resolution of Blu-ray (1920x1080). We appreciated that the screen features a matte finish, unlike the glossy screens that have become common on laptops, so you won't get as much glare in bright environments.

To control the DMP-B15, you can either use the controls on the top of the unit or the included remote. The top-mounted location of the controls allows the front of the DMP-B15 to have a sleeker look, but you'll have to lean over the unit to see what you're doing. We were happy to see a variety of controls available, including a small joystick so you can navigate menus without the remote. One click "up" with the joystick shows the pop-up menu and a click down makes it go away. The included remote is just a slight step up over the cheap credit-card-style remotes included on many inexpensive products. It's usable, but at this price we expected a bit more.
Features
If the DMP-B15 was just a portable Blu-ray player, it would be nearly impossible to justify its AU$1319 price tag. However, Panasonic has packed the DMP-B15 with almost as much functionality as its entry-level stand-alone Blu-ray player, the DMP-BD60, making it suitable to use in a home environment as well.

The main reason the DMP-B15K works as a stand-alone player is its HDMI output. Connect the DMP-B15 to an HDTV and it's capable of outputting high-definition video and high-resolution audio, just like larger units. For older TVs, there's also a composite AV output to be used with the included breakout cable. An SD slot is included and you'll need to insert a card (not included) to use BD-Live features. Rounding out the connectivity is a headphone jack and an Ethernet port. Just like the DMP-BD60, the DMP-B15K can access Panasonic's proprietary internet content portal, VieraCast, which includes YouTube and Picasa, with other features coming later in the year, according to Panasonic.

Also adding to the DMP-BD15's value is the inclusion of a few car accessories. There's a headrest mount that easily snaps into the back of the built-in stand, plus a cigarette lighter power adapter so you don't run out of juice on a long road trip.
Portable performance
When Panasonic rolled out the DMP-B15 at CES 2009, much of the tech community responded with scepticism about the usefulness of Blu-ray on an 8.9-inch screen. When many people claim to have a hard time seeing the difference between Blu-ray and DVD on a 50-inch screen, the DMP-B15 seemed like a step in the wrong direction.
However, we were surprised with the DMP-B15 when we actually put it through our testing procedure. You can see a difference between Blu-ray and DVD on the 8.9-inch screen, but you need to sit very close to it — about one foot away. That might sound like a sarcastic dig, but on an aeroplane, especially in economy, that's a realistic seating distance.
We had Batman Begins on both Blu-ray and DVD, so we swapped back and forth between the two discs. The Blu-ray version was clearly superior on scenes with a lot of detail. For example, in the monastery scenes in chapter two, the DVD had obvious softness and compression artefacts in images such as the finally detailed throne, while the Blu-ray looked excellent comparatively. However, the difference between the discs disappeared almost immediately as soon as you moved your head back another foot. The difference in image quality certainly isn't enough to justify the cost, but there's no denying that Blu-ray movies look better than DVDs on the DMP-B15.

Panasonic rates the battery life at three hours, but in our tests we achieved a little less than that at two hours and 28 minutes. This was enough time to get through Batman Begins but not The Dark Knight. It's definitely on the short side, and as the battery ages, you'll probably have difficulty even making it through a standard two-hour long movie. On the other hand, more flights are offering power outlets these days, so battery life may be less of a concern than it has been in the past. The included cigarette lighter power adapter also mitigates the issue somewhat for in-car use, although we'd prefer to not have the cable clutter. According to Panasonic, it will offer a six-hour battery later this year, but no details are available on its pricing or how it will add to the already bulky design.
Stand-alone performance
Despite its small size, Panasonic likes to claim that the DMP-B15 has "all the technology found in its stand-alone brethren, the DMP-BD60". However, that's not exactly true. When we connected the DMP-B15K via HDMI, we found that it cannot output Blu-ray movies in 1080p at 50 frames per second — the format that is commonly accepted by most HDTVs made in the last few years. Instead, the DMP-B15 can either output at 1080i or 1080p at 24 frames per second.
What that means for performance is that the DMP-B15 doesn't have much say on the resultant image quality. If you choose 1080i output, your HDTV will be responsible for deinterlacing the signal to 1080p (or whatever its native resolution is), so image quality will largely depend on your HDTV's video processing capability. If you choose 1080p/24, the DMP-B15K doesn't do much processing of its own — instead it simply takes the raw 1080p/24 data on the Blu-ray disc and passes it to your display. That being said, Blu-ray movies in 1080i or 1080p/24 looked as impressive as any stand-alone player on a variety of displays we checked.
Beyond image quality, we did experience a few freezes and glitches with the DMP-B15. The first full movie we watched, Batman Begins, made it all the way through glitch-free but playback got "stuck" for a couple of seconds during the credits. We ignored the stumble at the time — chalking it up to the fact that the battery was about to run out — but then we ran into more persistent issues with Mission Impossible: III, with the screen freezing or becoming garbled a few times during the movie. On the other hand, we made it through both Notorious and Slumdog Millionaire glitch-free, so the behaviour isn't consistent.
