Problems solved by technology

Furthermore, a large number of connecting wires (40 wires for the IDE / ATAPI bus) is undesirable in the automotive field, because a large number of connecting wires in the case of strong shocks and wide temperature fluctuations in the case of high connection reliability in the opposite direction tends to at the weaker point
Additionally, each connecting line also represents a cost factor

Embodiment Construction

[0022] figure 1 Illustrated is a module 1 for reading a data carrier 2 with the data carrier 2 in its insertion / ejection compartment. Wires 8, 9, 10 (shown here as flat cables with plug connectors) are provided for power and data exchange and coupling with the car radio. A disc-shaped data carrier 2 (in this case a CD / DVD) is transported by a mechanical element (not shown) to a drive unit and rotates on it, so that a radially moving data pickup can read the CD / DVD in a spiral pattern. The sequence of data presented by the structure.

[0023] figure 2 A car radio 15 is shown, which is designed to be incorporated within the dashboard of a car. The car radio 15 has a front 13 with a controller 11 , a display 12 and a slot 14 corresponding to the insert / eject compartment of the module. The module 1 is integrated in the car radio 15, which can be realized by screwing or locking or other known installation methods. The user can perform simple or complex operations via the cont...

Abstract

The present invention provides a module for reading data carriers, with a processor arrangement and a reading unit, - wherein the module is designed for incorporation in a data processing device, - wherein addressable coded data are stored on the data carrier, and - wherein the processor arrangement comprises a decoding function and is for this purpose designed for- receiving a request, characterized by an identifier, for decoded data which are stored in coded form on the data carrier,- controlling the reading unit such that the requested data, defined by a start address, are read in the coded form from the data carrier, - converting the coded data into decoded data by means of the decoding function, and - making the decoded data, characterized by the identifier, available.

Description

technical field [0001] The invention relates to a module for reading a data carrier, having a processor device and a reading unit. Background technique [0002] It is known to design modules to be built into or combined with car radios or navigation systems and to be able to provide these devices with ROM data (e.g. navigation data) derived from a data carrier such as CD-ROM or DVD-ROM. ). Navigation systems rely heavily on large amounts of data stored on data carriers. In this case, other data stored on the data carrier are frequently required, for example by a navigation system, in order to update the navigation information given to the user at regular intervals. This module reads the data carrier and is connected to the car radio or navigation system via the data / control bus. This data is requested by the car radio / navigation system from the module in the form of an address (eg Logical Block Address—LBA). This data is stored in standard blocks encoded on the CD-ROM. ...
