980 Protocol Scope for HDMI

The 980 Protocol Scope is an analyzer for HDMI source devices. It captures and decodes HDPC-protected video data content such as data islands, infoframes, audio sample packets as well as DDC transactions including HDCP, EDID and CEC data. An optional built-in 10.4 inch color touch screen provides a graphical user interface (GUI) to control the instrument and to view incoming video even when encrypted with HDCP.

You can capture and decode data with the 980 directly connected to a source or (optionally) while snooping between a source and a sink device ("pass-through") mode. In the direct mode, the 980 emulates a sink device and can capture all the video data. When in pass-through mode, the 980 monitors the video data passively between the source and sink. If the content from the source is HDCP encrypted, the 980 will capture all data up until encryption is enabled. Once encryption is enabled, the 980 collects only the DDC and CEC transacations and the timing parameters.

Analysis with the 980 Protocol Scope begins by setting the pre-capture filter and trigger criteria. Triggers and capture filters enable you to expedite your testing by ensuring that you capture the specific subset of data you are interested in. You can configure the capture criteria to capture and decode only the data types that you are interested in. Capturing less data--only the data you specifically need--enables you to capture more frames and in less time. After setting the precapture filter you then configure the trigger conditions. You can trigger on a variety of conditions or events that occur in the various data types and on specific values of a data type.

Once the data is captured, the 980 Manager presents the data in an easy to understand way through its graphical user interface. The decoded data is depicted at a high level view in the Event Plot panel and at a lower level view in the Data Decode panel. The Event Plot provides a timeline view of the various data types in relation to one another. The Data Decode panel provides a detailed sequential log with precise time stamps of each data transaction or event. You can apply post capture filters and searches on the data in the Data Decode panel.

The 980 also provides analyzer utilities for verifying the video timing, the consistency of the audio metadata and AVmute. These utilities provide at-a-glance insights into conditions that could cause interoperability problems.

 Key Features and Benefits

  • HDMI 1.3 support. Tests HDMI 1.3 source devices including deep color and x.v.Color.
  • Built-in touch screen display (Optional Feature). Enables you to control the 980 directly through the 980 built-in color touch screen display. Also enables you to view incoming video--even when encrypted with HDCP--as a confidence check and for controlling the menus of source devices.
  • Data Island Decoding. Decodes all data island types including: General Control Packets, AVI and Audio Infoframes, Vendor Specific Data, Source Product Descriptor, Audio Clock Recovery, Audio Sample packets—including the decoding of the Channel Status Bits and the control bits.
  • DDC Data Decoding. Decodes all DDC transactions including EDID reads and HDCP authentication. You can view HDCP registers in human readable text and pinpoint failures in authentication. For example you can easily determine if authentication fails due to improper setting of an HDCP register value or if HDCP registers are read at the wrong time.
  • Passive Monitoring (Optional Feature). Captures and decodes video passively between a source and a sink device. All data is captured if the content from the source is not HDCP encrypted. Once the source content is encrypted, only the DDC, CEC and timing parameters are captured.
  • CEC Data Decoding. View the CEC messages for addressing, routing, one touch play, etc.
  • Triggering and Precapture Filtering. Set up triggers on data island packet values as well as timing and control events. Use precapture filtering to capture the specific data you need.
  • Filtering of Data Transactions. Check box filtering allows you to remove data types from view that you are not interested in. Filter out all data islands except audio sample packets and audio infoframes, for example, to compare the respective values for sampling rate.
  • Searching Through Data. Search through the captured data to locate the specific occurrence of the data and or events you are interested in.
  • Timing Analysis. Verify timing parameters from HDMI source devices including all horizontal and vertical parameters and pixel clock. The timing values are compared against a set of standard timings and any deviation is indicated.
  • Audio Analysis. Verify audio metadata and identify inconsistencies that could result in interoperability problems.
  • AVmute Test. Verify that your source has implemented AVmute properly.
  • Pixel Values. View the component color values for any pixel including deep color video.
