Panasonic's DMP-B15 is portable Blu-ray viewer/player, that utilizes the same technologies as the full-sized Blu-ray players, so it can be used as a standalone player, or as a component in a home theater setup. It includes support for BD Live and Viera Cast functionality, which requires an Ethernet connection and opens the device to Amazon's Video on Demand, YouTube, Picasa Web albums, and more as services are added. As a portable device, the DMP-B15 is equipped with an 8.9" WSVGA LCD screen and can run for approximately 2.5 hours per battery charge, according to Panasonic.
