Pseudo-Sink for DisplayPort HDCP CTS

13-11-06, Juha Saarinen

Pseudo-Sink or Pseudo-Repeater

Section 3C of the DisplayPort HDCP CTS (Upstream Procedure with Transmitter) defines a set of tests to validate a DUT Repeater. Several tests in Section 3C require the use of so-called Pseudo-Sink or Pseudo-Repeater connected to the downstream port of the DUT Repeater.

The purpose of the Pseudo-Sink or Pseudo-Repeater is to simulate irregular procedures that may not be supported by regular HDCP compliant DisplayPort devices. With the published update Unigraf Reference Sinks can now be turned into such Pseudo-Sink or Pseudo- Repeater mode to be used along with Unigraf Reference Source to execute the tests in Section 3C.


The Pseudo-Sink capability can be used with Unigraf DPR-100 Reference Sink and UFG-04 DP Frame Grabber and SW release 3.3.4.
Unigraf DP HDCP tests for testing Sink and Branch devices are compatible with DPT-200 Reference Source and VTG-5225 DP Pattern Generator. The latest SW release is 3.3.2.
