CEC Interactive Troubleshooting Environment (ITE)

Overview

This chapter provides procedures for testing HDMI source and sink devices for CEC

functionality using the Interactive Troubleshooting Environment (ITE). When testing

HDMI-CEC source devices the generator (analyzer) will emulate a CEC sink device such

as an HDTV. When testing HDMI-CEC sink devices, the 882 generator will emulate a CEC

source device such as a set top box (STB) unless you instruct it not to.

Note: The CEC ITE is an option available on generators with release 2.2.2 or higher. You

must have the ITE option on your generator to use the ITE features. To determine if your

generator has the the ITE option installed, view the GenStats image and check the

information under Video Board - Options. Refer to “

Viewing generator configuration

information

” on page 117.

The CEC ITE provides a set of commands to accomplish the following:

•

Configure an HDMI port on the 882C(A) to emulate an HDMI source of sink

•

Send and query messages on the CEC bus

•

Query messages on the CEC bus

•

Monitor the CEC bus for timing errors
