Multimedia Device Integration System

Abstract

An multimedia device integration system is provided. One or more after-market audio or video devices, such as a CD player, CD changer, digital media device (e.g., MP3 player, MP4 player, WMV player, Apple iPod, portable media center, or other device) satellite receiver (e.g., XM or Sirius receiver), DAB receiver, video device (e.g., DVD player), cellular telephone, or any other device or combinations thereof, is integrated for use with an existing OEM or after-market car stereo or video system, wherein control commands can be issued at the car stereo or video system and data from the after-market device can be displayed on the car stereo or video system. Control commands generated at the car stereo or video system are received, processed, converted into a format recognizable by the after-market device, and dispatched to the after-market device for execution. Information from the after-market device is converted into a format recognizable by the car stereo or video system, and dispatched to the car stereo or video system for display thereon. One or more auxiliary input sources can be integrated with the car stereo or video system, and selected using the controls of the car stereo or video system. A docking station is provided for docking a portable audio or video device for integration with the car stereo or video system. Wireless integration between the portable audio or video device and a car stereo or video system is provided, and voice recognition and speech synthesis capabilities are provided in the portable audio or video device or the car stereo or video system.

AI Technical Summary

Benefits of technology

"The present invention is a multimedia device integration system that allows after-market audio and video devices to be connected to an existing car stereo or video system. The system uses a single interface to connect with the car stereo or video system and the after-market device, and includes software for converting signals from the after-market device into a compatible format for the car stereo or video system. The system can also include a docking port for connecting external audio devices and a display for displaying information from the after-market device. The technical effects of the invention include improved compatibility with after-market devices, improved user experience, and improved functionality and responsiveness of the car stereo or video system."

Problems solved by technology

Automobile audio systems have continued to advance in complexity and the number of options available to automobile purchasers.

Such early systems were closed, in that external devices could not be easily integrated therewith.

However, such systems often include proprietary buses and protocols that do not allow after-market audio systems, such as satellite receivers (e.g., XM satellite tuners), digital audio broadcast (DAB) receivers, digital media players (e.g., Apple iPod, MP3, MP4, WMV, etc.), CD changers, auxiliary input sources, video devices (e.g., DVD players), cellular telephones, and the like, to be easily integrated therewith.

Thus, automobile purchasers are frequently forced to either entirely replace the OEM audio system, or use same throughout the life of the vehicle or the duration of ownership.

Even if the OEM radio is replaced with an after-market radio, the after-market radio also frequently is not operable with an external device.

A particular problem with integrating after-market audio and video systems with existing car stereo and video systems is that signals generated by both systems are in proprietary formats, and are not capable of being processed by the after-market system.

However, such expansion modules only operate with and allow integration of external audio products manufactured by the same manufacturer as the OEM / after-market car stereo.

For example, a satellite receiver manufactured by PIONEER, Inc., cannot be integrated with an OEM car radio manufactured by TOYOTA or an after-market car radio manufactured by CLARION, Inc.

Thus, existing expansion modules only serve the limited purpose of integrating equipment by the same manufacturer as the car stereo.

However, such systems are often prone to interference, and do not provide high fidelity.
