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.
Claims5
An audio/video system for a motor vehicle, comprising a ring-shaped, bidirectional, optical network including optical fibers and audio/video appliances connected to one another in a ring shape by said optical network, wherein data are transmitted between said audio/video appliances in said network in a first data channel configured as a MOST network having a first optical wavelength and in a second data channel configured as an Ethernet having a second optical wavelength, each of said audio/visual appliances having an optical coupler with filters for separating said first and second data channels, wherein said first and second data channels have different bandwidths.
