On site PC Perspective has information confirming that the Zune HD media based on the platform nVidia Tegra. This argues that the information was privately sounded even at Computex 2009. NVidia Tegra processor was chosen because the lowest energy consumption. To decode the video stream requires 150 mW, but for audio playback - 20 mW, which corresponds to 10 hours of video playback and 25 days of continuous listening to audio files. Very good rates!
