A vehicle multimedia system simplifies a user's interaction with the system. A user may access a specific media unit by actuating a switch corresponding to a media unit. A preference unit detects the user's selection of the media unit and selects an end item based on a programmed criterion. The preference unit may automatically activate the end item. The preference unit may be overridden by the user when a switch corresponding to the selected media unit is actuated multiple times. The preference unit may also manage data lists and data packets that store the information used for the criterion comparison.

Activating a function of a vehicle multimedia system

An infotainment/telematics system includes a fixed base unit adapted to execute a set of stand-alone infotainment and/or telematics functions, and a portable communication device adapted to execute a stand-alone infotainment and/or telematics function. The fixed base unit and the portable communication device may be connected for intelligent communication with one another to allow the fixed base unit to control and access the stand-alone infotainment and/or telematics function of the portable communication device.

Extensible infotainment/telematics system having fixed base unit control of a portable communication device

An infotainment/telematics system includes a fixed base unit adapted to execute a set of stand-alone infotainment and/or telematics functions and a portable communication device adapted to execute a stand-alone infotainment and/or telematics function. The fixed base unit includes a user interface that is updated when the fixed base unit and the portable communication device are connected for intelligent communication with one another. Additionally, or in the alternative, the portable communication device may include a user interface that is updated when the fixed base unit and portable communication device are connected for intelligent communication with one another.

Extensible infotainment/telematics system having updatable user interface

A system includes a fixed base unit adapted to execute a first set of stand-alone infotainment/telematics functions and a portable communication device adapted to execute a second set of stand-alone infotainment/telematics functions. The first set of stand-alone infotainment/telematics functions may overlap with one or more of the second set of stand-alone infotainment/telematics functions. The fixed base unit and the portable communication device are connectable with one another for intelligent communication to shift at least one of the overlapping infotainment/telematics functions from the portable communication device or the fixed base unit to the other of the portable communication device or the fixed base unit. Shifting of the overlapping infotainment/telematics functions may be based on the relative processing power of the portable communication device and the fixed base unit.

Extensible infotainment/telematics system with process control shifting

An infotainment/telematics system includes a fixed base unit and a portable communication device. The fixed base unit may include a plurality of base unit devices cooperating with a base unit processor to execute a set of stand-alone infotainment/telematics functions. The portable communication device may include a one or more PCD devices cooperating with a portable communication device processor to execute a one or more stand-alone infotainment/telematics functions. The fixed base unit and the portable communication device may be connected for intelligent communication with one another to share and/or control a base unit device and/or a PCD device. Multiple portable communication devices may be connected to a single base unit to share the infotainment/telematics devices of the portable communication devices with the base unit and/or between the multiple portable communication devices. The fixed base unit may be fixed in a vehicle.

Extensible infotainment/telematics system

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. By the assignment of such a bit stream decoder centrally to the relevant data sink, the components of the individual subscribers are distributed in a more efficient manner within the network, which better utilizes the available data transmission capacity of the network, due also to the transmission of compressed data instead of decompressed data. Overall costs of the network are also reduced.

Local video and audio network with optical data line

An apparatus determines an optimal antenna and frequency combination by selecting the optimal antenna from among a plurality, N, of antennas associated with a receiver and also selects the optimal frequency from among a plurality, M, of alternative receiving frequencies transmitted from a transmitter. This is achieved by determining all N&#xd7;M possible antenna/frequency combinations, by determining the received signal quality at each combination, by comparing the N&#xd7;M received signal qualities, and by selecting the one antenna/frequency combination having the optimal received signal quality.

A navigation system for use in a motor vehicle receives starting position data and destination position data and computes driving directions between the starting and destination positions. The navigation system includes a first memory unit that stores a basic navigation database including road map information, and a receiver that receives supplemental navigation data including digital road maps, and provides received supplemental navigation data that is stored in a second memory unit. A navigation computer computes driving directions between the starting position and the destination position using information from the basic navigation database and the received supplemental navigation data, and outputs driving directions for presentation to a user.

Navigation system

A television receiver includes a tuner stage, a selective filter stage connected to the tuner stage, and a intermediate-frequency stage connected to the selective filter stage. A field-strength-detection stage is also provided, which generates a field strength signal proportional to the field strength of the received signal. The selective filter stage includes a transfer function that is modifiable by a control signal derived from the field strength signal.

Television receiver with dynamically adjustable filtering

The receiving device contains at least two television channel selection devices to convert high-frequency signals into intermediate-frequency signals, at least two video demodulation devices to convert the intermediate-frequency signals into picture signals, at least two audio demodulation devices to convert the intermediate-frequency signals into audio signals, and one intermediate-frequency switching device to switch the audio- and video-demodulation devices to the television channel selection devices.
