Abstract

A module carrier unit comprises a plurality of passenger interface modules that perform different functions, the functions including at least one of inputting and outputting information, the modules having a common size, shape, and interface; an outer case portion comprising a plurality of receptacles, each having a common size, shape, and interface designed to receive one of the modules, the plurality of receptacles being such that a first module having a first function is operable in a first receptacle, and a second module having a second function is operable in the first receptacle, the modules being removably connected to the receptacles; and a communications interface that performs at least one of transmitting and receiving data to and from a processor located near a seat of a passenger in the vehicle.

Claims

1. A video display unit for a vehicle, comprising

a module carrier unit directly affixed to a portion of the video display unit, comprising:

a plurality of passenger interface modules that perform different functions, the functions including at least one of inputting signals from one or more user devices and outputting signals to one or more user devices, the modules having a common size and shape case and a common electrical connector;

an outer case portion comprising a plurality of recessed sockets, each having a common size and shape and a common electrical connector, the plurality of sockets being configured so that any one of the passenger interface modules having the different functions is connectable to any one of the sockets to electrically mate the electrical connector of the one of the passenger interface modules to the electrical connector of the one of the sockets; and

a communications interface connected to a processor located near a seat of a passenger in the vehicle; and

a cover panel having holes in it, the cover panel being affixed to a portion of the video display unit and covering the module carrier unit while providing access to the passenger interface modules through the holes.

2. The video display unit according to claim 1, wherein:

the passenger interface modules are selected from the group consisting of a USB port, a DIN audio port, a headphone jack, an RCA video jack, RCA stereo audio jacks, and an attendant call button.

3. The video display unit according to claim 1, wherein the outer case portion is generally rectangular in shape.

4. The video display unit according to claim 1, wherein while the video display unit is upright the module carrier unit is directly affixed to the video display unit below a display.

5. The video display unit according to claim 1, further comprising:

a printed circuit board (PCB) comprising a bus extending between spaced apart electrical contacts which mate with the electrical connectors of the passenger interface modules while connected to the sockets.

6. The video display unit according to claim 5, wherein the PCB comprises:

a processor that processes signals sent to the one or more user devices through one or more of the passenger interface modules or that processes signals received from the one or more user devices through one or more of the passenger interface modules; and

memory by the processor during processing.

7. The video display unit according to claim 6, further comprising:

a communication protocol algorithm stored in the memory that when executed by the processor causes the processor to interface with the one or more user devices through one or more of the passenger interface modules.

8. The video display unit of claim 5, wherein the PCB comprises electrical signal level shifting circuitry that translates signals received from or provided to a user device connected to one of the passenger interface modules connected to one of the sockets of the module carrier unit.

9. The video display unit of claim 5, wherein the PCB comprises an analog-to-digital converter that translates signals received from or provided to a user device connected to one of the passenger interface modules connected to one of the sockets of the module carrier unit.

10. The video display unit of claim 5, wherein the PCB comprises a digital-to-analog converter that translates signals received from or provided to a user device connected to one of the passenger interface modules connected to one of the sockets of the module carrier unit.

11. The video display unit according to claim 1, further comprising:

hardware that performs multiplexed communication between the passenger interface modules and the processor through the communication interface.

12. The video display unit of claim 1, wherein:

the passenger interface modules while connected to the sockets of the module carrier unit provide a signal conductive pathway between the one or more user devices and an in-flight entertainment (IFE) server of an IFE system.

13. The video display unit of claim 1, further comprising circuitry configured to accommodate and adapt to a functional need of one of the passenger interface modules connected to one of the sockets of the module carrier unit.

14. The video display unit of claim 1, wherein the cover panel retains the passenger interface modules within the sockets while covering the module carrier unit.
