Abstract

A vehicle entertainment system comprising media player, master unit, slave units and smart devices to control the operation of master unit and slave units. A media placed in the media player can be played and shared between master and slave units. The media can be stored in a storage device to be played at a later time. The media content is shared between master and slave units via cable or wireless communication.

Claims

1. A vehicle video system comprising:

a master unit;

a plurality of slave units;

a plurality of smart devices;

a media player;

an operating system that resides in the master unit; and

an application program that controls the operation of the master unit and the media player wherein a video signal from the media player is sent to the master unit;

wherein the plurality of slave units are directly connected to the master unit and to the plurality of smart devices either by wires or wireless connection;

wherein the plurality of smart devices are directly connected to the master unit and to the plurality of slave units either by wires or wireless connection;

wherein the media player resides in the master unit; and

wherein the vehicle video system is installed within a vehicle;

wherein smart device is capable of displaying a video content coming from the master unit;

wherein the smart device controls the operation of the master unit and the slave units;

wherein the smart device can direct video from the master unit to any slave unit; and

wherein if there is a conflicting command coming from multiple smart devices, the master unit performs the last command received from any smart device.

2. The vehicle video system of claim 1 wherein a user can control the media player by entering at least one command to the master unit wherein at least one command is sent to the media player by the application program.

3. The vehicle video system of claim 2 wherein the master unit is installed in the head unit compartment of a vehicle seat.

4. The vehicle video system of claim 2 wherein the operating system is selected from a group consisting of Android operating system, Windows operating system, unix operating system, and Mac operating system.

5. The vehicle video system of claim 2 wherein the slave unit can accept commands from a user to turn the slave unit on or off and to increase or decrease the volume of the audio played on the slave unit.

6. The vehicle video system of claim 2 wherein the media played in the media player can be viewed on the slave device and on the smart device.

7. The vehicle video system of claim 2 wherein the smart device is selected from a group consisting of a smart phone and a smart tablet device.

8. The vehicle video system of claim 2 wherein the smart device has a video display.

9. The vehicle video system of claim 2 wherein the smart device does not have a video display and it has control buttons located on it.

10. The vehicle video system of claim 2 wherein the smart device further comprises a touch panel.

11. A method of displaying video signal on the vehicle video system of claim 2 the method comprising:

receiving command from the smart device;

decoding the command;

sending video to slave device and the smart device depending upon the command;

controlling different functions including volume; and

waiting for the next command.

12. The vehicle video system of claim 2 wherein the application program comprising the following steps:

initializing user interface;

initializing dynamic surface view and initializing listeners for events;

getting video decoder'"'"'s camera service;

running video decoder to get analog video signal from media player and outputting a digital video signal;

switching source to the selected video media in the video decoder;

booting up the image processing unit to receive digital video signal from video decoder;

sending digital video signal to dynamic surface view and display the view on the screen.

13. The vehicle video system of claim 12 wherein the application program further comprising the following steps:

running audio decoder;

switching source to audio in the audio decoder to get analog audio signal from media player;

outputting digital audio signal;

booting up audio processing unit to receive digital audio signal; and

converting and sending audio signal of proper format to an output source.

14. The vehicle video system of claim 13 wherein the application program further comprising the following steps:

receiving a user'"'"'s command either from a button or from a touch panel;

sending the user'"'"'s command to kernel driver;

adjusting the video decoder based on the user'"'"'s command wherein the user'"'"'s command can be selected from a group consisting of brightness, contrast, saturation, sharpness and hue.

15. The vehicle video system of claim 14 wherein the application program further comprising the following steps:

receiving a user'"'"'s command either from a button or from a touch panel;

sending the user'"'"'s command to kernel driver;

sending the user'"'"'s command to the media player; and

executing the user'"'"'s command wherein the user'"'"'s command can be selected from a group consisting of home, play, pause, stop, eject, next and previous.

16. The vehicle video system of claim 2 wherein the master unit sends a stream of data to at least one slave unit.
