UCD-301 DP and HDMI Test Sink


UHD/4K compliant video capture unit
for testing HDMI and DisplayPort Sources

UCD-301 Digital enables testing all aspects of HDMI 2.0 and DP 1.2 outputs. UCD-301 is also platform for HDCP 2.2 CTS Testing. UCD-301 is a DCP Approved test tool for testing HDCP 2.2 Transmitters on the DisplayPort interface.

UCD Console GUI is the preview and control application for UCD-301. The user can monitor and store the captured content, evaluate the upstream link status and control the link parameters.

UCD-301 is compatible with Unigraf high level software API called TSI. Combined with the TSI Test Cases, UCD-301 is a functionality testing tool with ready test routines for all supported interfaces.

USB Connected Frame Grabber

UCD series is a family of compact sized capture devices utilizing USB interface. They provide a flexible and robust way for both laboratory desktop debugging and automated testing of the functionality of the display interface. The dedicated hardware and the easy to apply high level SW library provide an optimal platform for creating sensitive but short cycle time functional tests.

UCD series frame grabbers are designed for test applications. UCD Console and Unigraf TSI SDK/API provides the test system integrator ready made high level Test Sets to verify a display interface. The details of the test sequence and the control of the test hardware are readily integrated in the high level Test Sets.


Test Automation

The presentation below introduces three case studies on testing the functionality of the HDMI interface of a Set-Top-Box, Game Console or Media Player with UCD-301. The tests reveal problems in interface signaling, EDID interpretation and HDCP decryption.
