Western Digital announced Tuesday the launch of its new WD TV Live HD Media Player. The WD TV Live is an upgrade over the previous WD TV model, now adding Ethernet connectivity and digital theater sound to its extensive features. Available now for $149.99, the WD TV Live hopes to transform your television into a home media hub.
The concept remains the same: you plug the WD TV into a television set and any external hard drive. The WD TV is designed to take your media files from your external hard drive and play them on your TV. To that end, the WD TV Live is equipped with an HDMI port and a USB port. The device supports many different types of audio and video files, such as H.264, MKV, VIDEO_TS folders, and FLAC audio, and can play back HD video in full 1080p resolution.
