I've seen the XStreamHD satellite service demonstrated for the last couple of years at CES, but so far, it hasn't actually been available to consumers. Well, that's finally about to changethe service is due to launch on April 30. It allows users to download movies, music videos, and games from a satellite to a hard-disk-based server, from which they can be streamed to several receivers in the homein fact, up to four HD streams can be served simultaneously. Users have the option of renting or buying the content, and they can even order physical discs if they wish. Movies are downloaded in 1080p/24 format with up to 7.1 DTS-HD MA audio (Dolby TrueHD is not supported as of now), and the server can download up to two titles at once, each with a maximum bandwidth of 100Mbps per stream.
