Abstract: A system matches frame counter values between a timing master and one or more slave devices in a synchronous network. To detect synchronization losses, a timing master counts transmitted frames of a continuous data stream. When a synchronization loss occurs, the timing master transmits a message to the slave devices that includes a synchronization frame counter value. The message synchronizes the frame counter value of the timing master to the frame counter value of the slave devices.

Abstract: A method for data transmission via several data channels in a network linking several units to one another, where the units can function as data sources, data sinks or transceivers, includes the steps of arbitrarily assigning a first data channel to a first predetermined one or more connection segments; arbitrarily assigning the first channel to a second predetermined one or more connection segments other than the first predetermined one or more connection segments; and simultaneously transmitting data between two units across the first predetermined one or more connection segments via the first data channel, and between two or more other units across the second predetermined one or more connection segments via the first data channel. The data are transmitted in a first direction over the first predetermined at least one connection segment, and the data are transmitted in a second direction over the second predetermined at least one connection segment, where the first ands second directions are the same.

Abstract: To transmit an anisochronic data stream on an isochronic transmission route with a plurality of channels over a transmission network, a number of channels is reserved by the transmitter before beginning the transmission, where the sum of the transmission capacities of the reserved channels just exceeds the bandwidth of the asynchronous data stream. During the course of transmission, the data of the anisochronic data stream are formed into packets; each packet is transmitted over the reserved channels. After a packet has been sent, unused portions of the reserved channels are filled with filler data that is discarded at the receiver, until sufficient data are again available at the transmitter to begin transmission of the next packet.

Abstract: An optical ring network for use, for example, in a motor vehicle, includes an optical data line that defines a ring network, a playback transducer and at least one data source connected to the optical data line, where the data source provides compressed data onto the optical data line. The network also includes at least one data sink connected to the optical data line, which receives the compressed data from the optical data line. The data sink includes a bit stream decoder that decompresses the received compressed data and provides the decompressed data to the playback transducer. The local network transmits audio and video data in compressed form via the data line, and has a single bit stream decoder, centrally situated at the respective data sink, for decompressing the audio and/or video data. As a result, the individual data sources no longer need their own bit stream decoder for decompressing the data.

The navigation system system also includes a navigation computing unit that recieves the first navigation system position signal and transmits onto a data bus (i) a first position signal indicative of the position of a trip starting location, (ii) a second position signal indicative of a trip destination location and (iii) the first navigation system position signal. A road map memory device includes map data.

Abstract: The utilization of the capacity of a data transmission system (e.g., a MOST vehicle network) is improved in the event that the operating frequency and channel width of the system do not match the word frequency and word width of the digitized signal. The data words of the digitized signal are decomposed into partial words with a smaller width than that of the channels on which they are transmitted. Consequently, in each individual channel there remains a residual transmission capacity that makes it possible to transmit an identifier for each individual transmitted partial data word. A data sink, connected to the transmission system, uses this identifier to obtain information about the position of the respective partial data word in its original data word. This identifier may be one bit (i.e., a Boolean signal).

Abstract: A multimedia system includes a housing having several shelves for receiving multimedia modules. Each module and each shelf is equipped with a plug connector element. The plug connector elements of the modules and of the shelves are compatible and are preferably designed as plugs and sockets. The plugs and the sockets can be designed in the same way so that each module can be plugged into each shelf, or they can be module-specific so that only a module designed for a particular shelf can be plugged into it. When a module is inserted into the shelf of the housing, the plugs are inserted into one another so that the module is now connected to the first bus line, which connects the plug connector elements of the shelves with one another. Over the second bus line other modules situated outside the housing or the rack can be connected to this first bus line. The first and the second bus line together form a common bus line, which is preferably designed as a ring line.

Abstract: An apparatus and method for efficiently managing data channels in a network such as a network implementing the commercially-available Media Oriented System Transport or Media Oriented Synchronous Transfer (MOST) network standard. A network implemented in accordance with the present invention optimally utilizes the limited number of data channels available on the network by assigning to a new connection a data channel that is currently assigned to another connection. This results in data channels having multiple assignments and occupations, increasing the transmission capacity of the network without increasing the total number of implemented data channels.
