Abstract: A telephone system for a motor vehicle includes a transmit/receive unit that transmits data over a wireless communication channel, and receives data over the wireless communication channel and provides a received signal. The system also includes a control unit that communicates with the transmit/receive unit; a first memory device; and a computing device. The computing device receives the received signal and automatically stores the received signal data in the first memory device when the telephone system is configured in a stand-by mode, which allows incoming data to be stored in the memory device while selectively preventing the transmission of outgoing calls originated by the control unit to the transmit/receive unit. Data can be sent to the motor vehicle telephone system and can be stored there for retrieval by the operator when he returns to the vehicle. The data may include audio and/or video data.

Abstract: The method for transmitting useful digital data from a first (1) to a second mobile station (5) saves computing costs and prevent data loss. In this method for transmission in a first network (10), the first station (1) source encodes useful data in a first step and then channel encodes the source encoded useful data in a second step. The encoded useful data are transmitted as a first bit stream to an intermediary station (15) via a transmission channel of the first network (10). The encoded useful data in the first bit stream are channel decoded by the intermediary station (15). For transmission in a second network (20), the useful data are again channel encoded by the intermediary station (15) and are transmitted to a second mobile station (5) via a transmission channel of the second network (20). Signalization data containing information regarding the encoding in the first step are transmitted from the intermediary station (15) to the second mobile station (5).

Abstract: In order to be able to reliably trigger an emergency call from a vehicle with a radio telephone (T), even in the case of a heavy crash or collision, an autonomous emergency call unit (N) is arranged in a position in the vehicle particularly well protected from damage by collision or crash. An emergency call is triggered, for example, by a gyro (K), provided as a crash detector, which activates the emergency call unit (N) in a mechanical manner, which then transmits an emergency call to the radio telephone (T) over a short radio path according to the bluetooth standard for example, which then further transmits the emergency call to an emergency call exchange (Z) over a radio path (F). The autonomous emergency call unit (N) is provided with a bluetooth transceiver unit (BE), a battery (BA), a gyro (K) and a GSM transceiver (GSM) which transmits an emergency call to the emergency call exchange (Z) should the radio telephone (T) be damaged or destroyed.

Abstract: A wireless communication system allows mobile users to access a resource from a content server. The wireless communication system includes a browser that allows mobile users to access resources through a wireless application protocol (WAP) compliant server. The (WAP) compliant server connects the browser to a content server. This connection allows resources to be passed between the browser and the (WAP) compliant server. The browser is further configured to transmit a request that includes an address for a resource, a protocol to be used, and one or more textual parameters encoded into a binary data packet. The wireless communication method includes generating a request for a resource; translating a textual portion of that request into binary data at the browser; transmitting the request to a wireless gateway; and converting the request into a format that is compatible with a protocol used by a receiving network.

Abstract: In a multimedia system for a vehicle, a plurality of multimedia units are connected to one another by an optical bus laid as a ring line. An interface unit, situated at an arbitrary point in the ring line or integrated into one of the multimedia units establishes a radio connection between the multimedia system and an external unit, which for example transmits traffic information to the multimedia system.

Abstract: A system is presented for utilizing data in a mobile device in real-time and without the need for additional hardware. The system allows real-time processing of highly-compressed data that would otherwise require processing power in excess of that available from the system, or would otherwise not be possible without additional hardware. The system generally includes a processing device that receives the data in a highly compressed format, and includes a preprocessor that pre-processes the data to at least partially decode the data into a second compressed format. The processing device also includes a decompressor that fully decompresses the preprocessed data as needed by the system. The processing device may also include one or more memories for storing the preprocessed data until it is needed by the system.

Abstract: To make possible communication between a MOST network and an external receiver and an external transmitter, the MOST network is connected to an interface, which transforms data in the MOST standard into a standard suitable for the external receiver, and transforms data received from the external transmitter into the MOST standard.

Abstract: To avoid misconnections and to increase data protection during communication between devices (1 to 9), which are linked with one another in a first network (M) and devices linked with one another in a second network (I), a second address is assigned to each device (1 to 9) in addition to a first address which identifies the device in the first network (M). This second address is formed by connecting the first address to a mathematical formation algorithm, e.g. a prefix. This second address makes it possible to identify the devices linked with one another in the first network (M) as devices belonging to the second network. It is especially advantageous to choose the prefix in such a way that the second addresses are interpreted as private addresses in accordance with the definition rfe 1918. The inventive method is especially suited for communication between a private network, e.g. an MOST network (M) installed in a vehicle, and a public network, e.g. the Internet (I).

Abstract: A network that provides a simple mechanism for communicating between the network, such as a MOST network installed in a motor vehicle, and a second network, such as the Internet. One unit of the network includes a network layer of the second network as well as an associated application interface (API). The network layer is an Internet Protocol (IP) or Transmission Control Protocol (TCP) network layer. Also installed in the network unit is an associated application program interface. Together, the network layer and API enable the network units in first network to communicate with the second network. Proxy computers are installed in the remaining units to substantially reduce technical complexity without impairing communication with the second network.

Abstract: To design a network, e.g. an MOST network, so that it can also process data telegrams of other standards, the header section (A) of the data telegram, formatted in accordance with the standard of the network or in accordance with another standard, contains standard information, which specifies that the remaining section (B, C) of the data telegram is formatted in accordance with a second standard (TCP/IP), and also specifies this standard.

Abstract: To enlarge the possible applications of a car telephone, its control unit can be turned-off. The wireless telephone is blocked for outgoing calls, but is on standby for incoming calls so data arriving during calls can be stored in a memory. The operator can at any time query these stored data. The operator can block undesired callers against reception. Furthermore, he can program the car telephone, for example, in such a way that it sends requests at prescribed times to prescribed communication services, in order to receive data from these, which likewise are stored in the memory.

Abstract: To make it easier for a subscriber to operate a wireless phone and a transceiver in a vehicle, the transceiver transmits an identification to the wireless phone within a limited transmission and reception range. When the wireless phone receives this identification, it transmits its identification data to the transceiver to inscribe itself in the transceiver. Alternatively, the wireless phone transmits its identification data within a limited transmission and reception range, and the transceiver receives this identification data and that the wireless phone is inscribed (i.e., registered) with the transceiver. The transceiver acts as interface for calls to and from the wireless phone.

Abstract: The process for data transmission between two stations by means of data blocks each having a synchronization pattern field (SYNC), a header field (HEADER) and an information field (INFORMATION) following the header field includes providing a header control field (HEX) following the header field (HEADER) in each of the data blocks for reconstruction of the header field when a transmission of the header field contains errors.

Abstract: The process for transmission of images enables various classes of source-coded image data to be channel-coded and transmitted at various class code rates. For this purpose, source-coded image data to be transmitted are divided into classes of different sensitivity with respect to transmission errors and the classes are provided with different error protection and are channel-coded for transmission. Information words are provided at the beginning of each class containing information regarding the class type, code rate, number of data bits belonging to a particular class and regarding the error protection employed. In addition, a synchronizing word is added to the image data for each image. In the receiver the first information words are channel-decoded according to a fixed code rate and the information stored in the first information words including code rate is used for the channel-decoding of the received coded image data. The image data are subsequently subjected to an image source decoding and read out.
