Product Features

The UCD-323 is a fully-featured R&D debug tool for testing all aspects of HDMI 2.0 and DisplayPort 1.4a (limited to HBR2 max bit rate capability). The UCD-323 combines Reference Source and Reference Sink functionality in one unit. The UCD-323 is a DCP LLC Approved Test Tool for HDCP 2.3 CTS Tests on DisplayPort Transmitters and Receivers devices. The UCD-323 is delivered with ready-made test sets that are configured and able to run via easy-to-use PC GUI called UCD Console.  All tests can be automated for compliance testing, R&D debugging, and production line testing.


Approved Dolby Vision Compatibility Test Tool

Unigraf’s UCD-323 has been approved as an official Dolby Vision™ compatibility test tool. In the compatibility test for Dolby Vision™ Unigraf will provide playback and capturing of the test video and audio content with UCD-323. In addition, UCD-323 can be used to test Dolby Atmos on Source DUTs. Further, Dolby will provide customers with the SDK (Software Development Kit) that enables analyzing the Dolby Vision™ video captured with the UCD-323. As of now, Dolby Vision™ testing is available for HDMI interface. UCD-323 also supports Dolby Vision signaling test using Dolby Vision VSIF and Dolby Vision Vendor Specific Extended Metadata Packets (EMP) using TMDS. With the Dolby SW package, UCD-323 is a mandatory tool for any e.g. television or monitor manufacturer that is willing to have a Dolby Vision™ certificate on their products.


Approved HDR10+ Display Device Test Tool

Unigraf’s HDR 10+ Display Device Test License (MT6675), allows HDR 10+ adopters to generate HDR 10+ specific patterns that are required by HDR 10+ LLC to certify Sink devices such as TVs and Monitors for HDR 10+.

Unigraf’s solution integrates Klein K-10A colorimeter for automated testing of HDR 10+ Display Device tests allowing users to set and play the patterns without having to manually measure luminance values of HDR 10+ patterns. Users that do not have Klein K-10A colorimeter will be able to manually record measured luminance values into the software GUI. This solution is easy to use and reduces the time required to run HDR 10 Display Device certification tests.


Reliable Compliance Testing Tool

UCD-323 is a DCP LLC Approved Test Tool for HDCP 2.3 Compliance Testing on DisplayPort Transmitter and Receiver devices. HDCP 2.3 Compliance Test capability is an add-on feature to the UCD Console GUI. HDCP 2.3 CTS tests can be straightforwardly enabled to any UCD-323 Test Tool with an SW add-on. The software add-on can be purchased separately for testing transmitter or receiver devices.


Platform for Test Automation

Run automated tests straight from the command line by using C++ code. Unigraf also provides users with a library of scripts that can be used an example for detailed tests. The scripts are run through Unigraf’s Test System Interface (TSI) which is the test software API that allows system integrators a fast and reliable way for ensuring the functionality of the test equipment. These scripts can be used to automate all the tests available in the UCD-323, including Compliance Tests for HDCP 2.3.


UCD Console

The UCD-323 Graphical User Interface (GUI) is called UCD Console. It provides users with a flexible way of navigating between its sink and source roles and functionalities of each role. Available functionalities include preview windows for captured video and audio, video and audio pattern generator, data logger for AUX and metadata content, link and DPCD register monitoring and control dialogs, EDID editor, HDCP status and control functions etc. UCD Console is delivered with ready-made test sets (e.g. content check-sum tests and Link Training tests) for testing HDMI Sinks and Sources.
