HT-180 Handshake Tester for

HT-180 – Current Status Built on the technology of our 882 HDCP compliance test feature – the worlds first and only commercially available HDCP Compliance Test application. Troubleshoots HDCP, HPD and EDID interoperability problems and helps identify problems. Provides both up-steam and down-stream views of HDMI component interactions. Enhanced localization features anticipated -- LCD display with error code reporting -- Save “Trace” Files

HT-180 – What does it do? Assists in the troubleshooting of HDMI Interoperability and handshake problems Identifies 5V, Current and Hot Plug Issues Identifies EDID problems Localizes HDCP handshake problems

HT-180 – Typical root causes EDID Failures -Checks if EDID port was not acknowledged -Checks if EDID port access was attempted by source -Verifies that EDID header and checksums are valid -Checks if EDID read was triggered by hot plug detection Hot Plug Failures -Checks hot plug for < 100ms deassertion -Verifies that hot plug downstream assertion is passed to upstream -Checks if hot plug detection assertion upstream was not the result of downstream problem -Measures +5v signals for voltage and current draw on a source HDCP Failures -Checks for invalid Aksv from source -Verifies that source write of An occurs prior to write of Aksv -Verifies that source read of Bcaps occurs prior to read of R0’ -Verifies that source write of Aksv occurs prior to read of R0’ -Checks for invalid Bksv from sink -Checks if Ri’ is read without second phase of authentication (in case of repeater) -Checks if HDCP reauthentication was triggered by hot plug detection -Checks if HDCP port is not acknowledged -Checks for excessive HDCP re-authentication attempts by source -Verifies that source attempted to access sink HDCP port -Checks if the READY bit is not set as a result of any of the following failure conditions: Repeater did not attempt to read Bksv downstream receiver Source did not begin reauthentication after five seconds Invalid Bksv

HT-180 – Operation HT-180 is inserted in an HDMI system. The product will test up to Three different devices for interoperability problems by displaying Error codes on the LCD as well as in HTML trace files.

HT-180 – Operation Set up a trace using Immediate evaluation on displayed on the LCD Set up a trace using the trace file capture software Running on a connected PC

HT-180 – Operation Ticket No. Customer Info Products!! System Captured trace files allow system information to be sent to a lab for analysis. Each trace can specifically identify the components of the system tested, date and location.

HT-180 – Enhanced failure indication (DDC Protocol Traces) Reason & action codes -Digests DDC protocol data -Provides root cause code -Documentation provides corrective action DDC protocol traces -USB captures DDC data -Customer service call card with documentation associates activity with DDC trace files

HT-180 – Enhanced failure indication (reason & action codes) Error Codes are shown on the LCD, indicating more precise failure mode and referring to a list of causes as well as possible solutions. Additionally, an “A”, “B” or “C” rating can suggest Severity of the diagnosis.
