High definition multimedia interface test system

摘要

A high definition multimedia interface (HDMI) test system including an HDMI test device that includes a display, a microcontroller, first and second input ports, an output port, a first cable connector, a second cable connector, and a third cable connector. The HDMI test device couples to an external device and receives an HDMI signal from the external device via the first cable connector. The microcontroller receives the HDMI signal from the first input port and converts the signal to a video signal, wherein the display displays an image associated with the video signal. The microcontroller transmits a test HDMI signal to the third cable connector, receives the test signal from the second cable connector and compares the test signal transmitted to the third cable connector and the test signal received from the second cable connector to determine continuity of an HDMI cable coupled with the second and third cable connectors.

主权项

1. A high definition multimedia interface (HDMI) test apparatus comprising:
an HDMI test device comprising a housing, wherein said HDMI test device with said housing comprises
a display,a microcontroller,a first input port,an optional second input port,an output port,a first cable connector coupled to the first input port,a second cable connector coupled to the second input port, and,a third cable connector coupled to the output port, wherein the HDMI test device is configured to
couple to an external device via an HDMI cable, andreceive an HDMI signal from the external device over the HDMI cable via the first cable connector that is coupled with the first input port; wherein the microcontroller is configured to
receive the HDMI signal from the first input port,convert the HDMI signal to a video signal, andsend the video signal to the display; wherein the display is configured to display at least one image associated with the video signal; wherein the microcontroller is further configured to
transmit a test HDMI signal to the third cable connector via the output port,receive the test HDMI signal from the second cable connector via the second input port or from the first cable connector via the first input port,compare the test HDMI signal transmitted to the third cable connector via the output port and the test HDMI signal received from the second cable connector via the second input port or from the first cable connector via the first input port to determine continuity of the HDMI cable coupled with the second cable connector and the third cable connector, and,display a continuity diagram that shows continuity wires in the HDMI cable on the display; and, wherein said microcontroller is further configured to alter information displayed on said display according to a first mode and a second mode, wherein the first mode comprises an HDMI video display mode, and wherein the second mode comprises an HDMI cable test mode.
