2HT-180 – Current Status Built on the technology of our 882 HDCP compliance test feature – the worlds first and onlycommercially available HDCP Compliance Testapplication.Troubleshoots HDCP, HPD and EDID interoperabilityproblems and helps identify problems.Provides both up-steam and down-stream views ofHDMI component interactions.Enhanced localization features anticipated-- LCD display with error code reporting-- Save “Trace” Files
3HT-180 – What does it do? Assists in the troubleshooting of HDMI Interoperability and handshake problemsIdentifies 5V, Current and Hot Plug IssuesIdentifies EDID problemsLocalizes HDCP handshake problems
4HT-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 detectionHot 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 sourceHDCP 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 receiverSource did not begin reauthentication after five secondsInvalid Bksv
5HT-180 – OperationHT-180 is inserted in an HDMI system. The product will test up toThree different devices for interoperability problems by displayingError codes on the LCD as well as in HTML trace files.
6HT-180 – Operation Set up a trace using Immediate evaluation on displayed on the LCDSet up a trace usingthe trace file capture softwareRunning on a connected PC
7HT-180 – OperationTicket No.Customer InfoProducts!!SystemCaptured trace files allow system information to be sent to a lab foranalysis. Each trace can specifically identify the components of thesystem tested, date and location.
9HT-180 – Enhanced failure indication (reason & action codes) Error Codes are shown onthe LCD, indicating moreprecise failure mode andreferring to a list of causesas well as possible solutions.Additionally, an “A”, “B” or“C” rating can suggestSeverity of the diagnosis.
15HT-180 Diagnosis & Study The HT-180 will provide a convenient method for identifyinginteroperability problems inthe field and help serviceproviders develop strategiesfor solving customerdigital HD installation problems.
