I2C SIGNAL ANALYSIS IN THE HDMI INTERFACE

The HDMI (High-Definition Multimedia Interface) standard is based on the DVI (Digital Visual Interface) standard. The HDMI standard has addressed the requirements for a next generation visual interface adapted by non PC applications such as DVD players or STB.

Just like DVI standard, HDMI contains a signal to exchange information among connected devices in addition to the visual
signal. This signal is called DDC (Display Data Channel)and the I2C standard was selected for this purpose.
The I2C bus trigger/analysis function of the DLM2000/DL9000 can be used for the analysis of this signal.

Oscilloscopes

Oscilloscopes are a common type of test instrument used to capture, analyze, and troubleshoot electrical or real world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
