## Abstract

An apparatus for converting HDMI to FPD-link III signals in automobiles. The apparatus includes a USB to I2C bridge allowing USB interfaced commands to configure and update a USB to I2C Bridge, I/O Expander, EEPROM and FPD-link III Serializer that convert HDMI inputs to FPD-link III outputs. The apparatus also includes an EEPROM configured to hold video timing configurations for the Device Under Test as well.

## Claims

### Claim 1

A Flat Panel Display (FPD)-link III converter apparatus comprising:
a USB interface;
a USB to I2C bridge in communication with the USB interface;
an FPD-link III serializer in communication with the USB to I2C bridge, where the FPD-link III serializer has at least one output port; and
an HDMI port in communication with the FPD-link III serializer.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising:
an input/output expander in communication with the USB to I2C bridge, and
an enabler circuit in communication with the input/output expander and at least one output for an enabling signal.

### Claim 3 (depends on 1)

The apparatus of claim 1, further comprising:
an EEPROM in communication with both the HDMI port and the USB to I2C bridge.

### Claim 4 (depends on 3)

The apparatus of claim 3, where the EEPROM comprises instructions for input video timing configuration for a device under testing.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising:
a power input; and
a power converter, where the power converter transmits electrical power to at least one of the USB to I2C bridge and the FPD-link III serializer.

### Claim 6

A system for providing media in FPD-link III format to a device under testing, the system comprising:
a processor;
a memory in communication with the processor and containing a program that, when executed, configures the processor to provides a graphical user interface;
a display in communication with the processor; and
an FPD-link III converter apparatus comprising:
a USB interface;
a USB to I2C bridge in communication with the USB interface; and
an FPD-link III serializer in communication with the USB to I2C bridge, where the FPD-link III serializer has at least one output port configured to communicate with the device under testing; and
an HDMI port in communication with the FPD-link III serializer.

### Claim 7 (depends on 6)

The system of claim 6, wherein the program on the memory is configured to modify programs on at least one of: the USB to I2C bridge, and the FPD-link III serializer.

### Claim 8 (depends on 6)

The system of claim 6, wherein the apparatus further comprises:
an input/output expander in communication with the USB to I2C bridge, and
an enabler circuit in communication with the input/output expander and at least one output for an enabling signal.

### Claim 9 (depends on 8)

The system of claim 8, wherein the program on the memory is configured to modify a program on the input/output expander.

### Claim 10 (depends on 6)

The system of claim 6, wherein the apparatus further comprises:
an EEPROM in communication with both the HDMI port and the USB to I2C bridge.

### Claim 11 (depends on 10)

The apparatus of claim 10, where the EEPROM comprises instructions for input video timing configuration for the device under testing.

### Claim 12 (depends on 10)

The apparatus of claim 10, wherein the program on the memory is configured to modify a program on the EEPROM.

### Claim 13 (depends on 6)

The system of claim 6, wherein the apparatus further comprises:
a power input; and
a power converter, where the power converter transmits electrical power to at least one of the USB to I2C bridge and the FPD-link III serializer.
