Introducing the latest video test instrument from Quantum Data for testing HDCP interoperability in HDMI systems. The HT-180 Handshake Tester for HDMI
offered by Quantum Data enables users in R & D labs, service provider interoperability labs and field service techs to identify the root cause of HDCP, EDID and
hot plug related interoperability problems in HDMI systems. The HT-180 provides HDMI ports for passive connection into an HDMI system comprised of a source
(e.g. set top box or DVD), repeater (e.g. AVR controller) and an HDTV.
A graphical utility is provided for users to enter information about the site and the equipment in the HDMI system under test. Tests are initiated with the press of a
button. When the test is complete, the unit’s LCD display presents simple reason codes with severity levels to identify suspect behavior of specific HDMI products
in the system. During the test, the HT-180 monitors the HDCP, EDID and hot plug transactions over the I2C bus, analyzes the results and stores the transactions
in a log file. The log files can be viewed with the Auxiliary Channel Analyzer on-site or later during post analysis of HDMI system problems.
