  • Audio and/or video system for a motor vehicle
    Patent number: 7926077
    Abstract: The invention relates to an audio and/or video system for a motor vehicle, which comprises an annular, bi-directional, optical network (1) from optical waveguides and audio and/or video devices (2-12) that are interlinked by means of the network (1) in an annular manner. Data are transmitted between the audio and/or video devices (2-12) in the network (1) in a first data channel having a first optical wavelength. The network used is especially a MOST bus known for use in motor vehicles. The invention is characterized in that data are transmitted between the audio and/or video devices (2-12) in the network (1) in a second data channel having a second optical wavelength. Particularly, IP data can be transmitted at a high transmission rate via the second data channel.

  • Switching system with improved message distributor
    Patent number: 6847642
    Abstract: In a switching system with improved message distributor in which a common internal bus is used in order to improve the transmission of messages between a switching network connecting unit, a coordination processor connecting unit and a signaling connecting unit are provided. In this way, loading on the co-ordination processor can be reduced and the system power of the switching system can be increased.
