Abstract

A data distribution unit for a vehicle includes wireless receiver configured to receive coded data wirelessly via a cellular network, a signal processor configured to decode the coded data into video data and audio data, and a wireless transmitter configured to transmit the video data wirelessly to a display and transmit the audio data wirelessly to a speaker.

Claims

1. A data distribution unit for a vehicle, comprising:

a wireless receiver configured to receive coded data wirelessly via a cellular network;

a signal processor configured to decode the coded data into video data and audio data; and

a wireless transmitter configured to transmit the video data wirelessly to a display and transmit the audio data wirelessly to a speaker.

2. The data distribution unit of claim 1, wherein the wireless receiver is configured to receive the coded data wirelessly via a Third Generation (3G) cellular network or a Fourth Generation (4G) cellular network.

3. The data distribution unit of claim 1, wherein the wireless receiver is configured to receive the coded data wirelessly via an Evolved High-Speed Packet Access (HSPA+) cellular network, a Worldwide Interoperability for Microwave Access (WiMAX) cellular network, or a Long Term Evolution (LTE) cellular network.

4. The data distribution unit of claim 1, wherein the wireless transmitter is configured to transmit the video data and the audio data wirelessly using an 802.11 transmission standard.

5. The data distribution unit of claim 1, wherein the wireless transmitter is configured to create a hotspot by assigning an Internet Protocol (IP) address to at least one wireless enabled device via an 802.11 transmission standard.

6. The data distribution unit of claim 5, wherein the at least one wireless enabled device comprises one of a laptop, an mp3 player, a gaming system, a personal digital assistant (PDA), or a cellular phone.

7. The data distribution unit of claim 1, wherein the display and the speaker are part of a portable media player.

8. The data distribution unit of claim 1, further including a browser configured to navigate an Internet website on the display.

9. The data distribution unit of claim 1, wherein the display is mounted to a headrest of a seat in the vehicle, and the data distribution unit is mounted on a surface within the vehicle.

10. The data distribution unit of claim 1, further comprising:

a video camera configured to record local video data; and

a microphone configured to record local audio data.

11. The data distribution unit of claim 10, wherein the data distribution unit is configured to transmit the local audio and video data to a remote device wirelessly via the cellular network, receive remote audio and video data from the remote device wirelessly via the cellular network, and transmit the remote audio data to the speaker and the remote video data to the display wirelessly via an 802.11 transmission standard.

12. The data distribution unit of claim 10, wherein the display, the video camera, and the microphone are mounted to a headrest of a seat in the vehicle, and the data distribution unit is mounted on a surface within the vehicle.

13. The data distribution unit of claim 10, wherein the display and the video camera are mounted in a dashboard of the vehicle, and the microphone and the speaker are mounted in an overhead of the vehicle.

14. The data distribution unit of claim 1, further comprising:

a plurality of displays;

a plurality of video cameras; and

a plurality of microphones,

wherein a first display, a first video camera and a first microphone are mounted in a dashboard of the vehicle, and a second display, a second video camera and a second microphone are mounted in a headrest of a seat in the vehicle.

15. The data distribution unit of claim 14, wherein functions of the first display, the first video camera and the first microphone are controllable by a first controller, and functions of the second display, the second video camera, and the second microphone are controllable by a second controller.

16. The data distribution unit of claim 1, further comprising a storage device.

17. The data distribution unit of claim 16, wherein local data is stored in the storage device, and the local data is transmitted wirelessly to the display, the speaker, and at least one wireless enabled device via the wireless transmitter using an 802.11 transmission standard.

18. The data distribution unit of claim 1, further comprising:

a data bus; and

a selection multiplexer connected to the wireless receiver and an additional media source, wherein the selection multiplexer is configured to multiplex one of data corresponding to the wireless receiver or data corresponding to the additional media source to the data bus.

19. The data distribution unit of claim 18, wherein the wireless transmitter is configured to wirelessly transmit the data multiplexed to the data bus to at least one of the display, the speaker, or a wireless enabled device via an 802.11 transmission standard.

20. The data distribution unit of claim 1, further comprising an additional wireless transmitter, wherein the wireless transmitter is configured to create a first hotspot having a first access level by assigning an Internet Protocol (IP) address to a first wireless enabled device via an 802.11 transmission standard, and the additional wireless transmitter is configured to create a second hotspot having a second access level, different from the first access level, by assigning an IP address to a second wireless enabled device via the 802.11 transmission standard.
