"On2 Technologies announced at the 2005 Consumer Electronics Show (CES) that XM Satellite Radio will use its TrueMotion VP6.2 video compression technology in XM's in-vehicle prototype video entertainment system. The new system will be used to transmit video entertainment to satellite receivers in automobiles. The video signal will be used primarily for back- seat entertainment with content that can be either streamed in real time or and cached for later playback. After evaluating codecs from several other vendors, XM selected TrueMotion VP6.2 because of its excellent performance in this kind of environment. In XM's tests, competing video codecs failed to achieve the same results. XM and its automotive equipment partners are demonstrating the satellite entertainment prototype in a new technology showcase vehicle this week at CES in Las Vegas."I guess the announcement that Sirrus was going to offer video caused XM to announce this. Honestly I would think using Windows Media would be the better choice for consumers, but maybe in the end it won't matter.
