A cool, upcoming Blu-ray drive uses only a single USB connection.
DVICE is reporting that Asus is gearing up to launch an external Blu-ray player later this month. According to the website, the SBC-04D1S-U external Blu-ray drive only offers one connection: USB 2.0. Apparently, the drive doesn't offer any other type of output--no HDMI, no AC power jack, but rather sends and receives through the single USB port.
In addition to reading 4.8X Blu-ray discs, the external drive is also capable of writing 8X DVD-Rs and CD-Rs. Asus also said that the drive features a "Turbo Engine for enhanced USB Connectivity" which is probably what helps the drive crank out HD video to the monitor without additional video cables.
Additionally, the Blu-ray drive uses TrueTheater High Definition, transforming standard content into HD-quality images on high-resolution displays. The drive also comes with a vertical stand, Disc Encryption, and additional Cyberlink software. Currently there's no pricing available, however stay tuned for more in the next several weeks.
