Abstract: Apparatus and methods are provided for wirelessly broadcasting large multimedia files to vehicles. The apparatus includes a vehicle-based receiver configured to wirelessly receive at least one group of encoded data packets at a data rate based on a number of concurrently broadcasted groups of encoded data packets, a decoder coupled to the data storage device, a data storage device coupled to the receiver, and a media playback unit coupled to the data storage device. The group of data packets corresponds to at least a portion of a multimedia content, and each of the data packets contains at least a portion of the multimedia content. The data rate is based on an average vehicle operation duration and/or a probability of occurrence of the average vehicle operation duration. The decoder is configured to assemble at least a portion of the multimedia content from the first data file upon the data storage device receiving a pre-determined number of data packets. The data storage device is configured to store the group of data packets and assembled multimedia content. The playback unit is configured to play the assembled multimedia content.

Abstract: Methods and apparatus are provided for generating route instructions on a turn-by-turn navigation system in a vehicle. Turn instructions can include a turn icon as well as visual and audio prompts. The turn-by-turn navigation system includes special routing features, such as “Where am I”, “Verification”, “Stop by”, pre-set destinations, and time-restricted road routing. The turn-by-turn navigation system can generally be produced more economically than a typical premium system having a full complement of costly features, such as a color map display. Moreover, the turn-by-turn navigation system can be configured with only those features deemed most useful to a broad-based market segment, in order to further reduce manufacturing costs.

Abstract: Methods and apparatus are provided for insuring that a motor vehicle is being operated by an authorized operator. The apparatus includes an electronic control unit (ECU), an engine immobilizer unit, and a shared encryption key. The ECU generates a challenge by combining the output of a pseudo-random number generator and the output of a somewhat random number generator and cycling the combined number through a linear feedback shift register. The ECU sends the challenge to the immobilizer unit where it is encrypted with the shared key and sent back to the ECU as a response. The ECU uses the same key to encrypt the challenge and compares the encrypted challenge to the response. If the response matches the encrypted challenge, engine operation is enabled.
