Overview

This file contains a design example using the XDpTxSs driver in single stream (SST) transport or multi-stream transport (MST) mode and enables HDCP.

Note
For this example to display output, the user need to implement initialization of the system (DpTxSs_PlatformInit) and after DisplayPort TX subsystem start (XDpTxSs_Start) is complete, implement configuration of the video stream source in order to provide the DisplayPort TX Subsystem HIP input. The functions DpTxSs_PlatformInit and DpTxSs_StreamSrc are declared and are left up to the user implement.
MODIFICATION HISTORY:
Ver  Who Date     Changes


2.00 sha 09/28/15 Initial release. 4.1 ms 01/23/17 Modified xil_printf statement in main function to ensure that "Successfully ran" and "Failed" strings are available in all examples. This is a fix for CR-965028.

Function Documentation

u32 DpTxSs_HdcpExample ( u16  DeviceId)

This function is the main entry point for the HDCP example using the XDpTxSs driver.

This function will enable HDCP during DisplayPort TX Subsystem set up to work in MST/SST mode.

Parameters
DeviceIdis the unique device ID of the DisplayPort TX Subsystem core.
Returns
  • XST_SUCCESS if DisplayPort TX Subsystem HDCP enabled successfully.
  • XST_FAILURE, otherwise.
Note
None.

u32 DpTxSs_PlatformInit ( void  )

This function initialize required platform-specifc peripherals.

Parameters
None.
Returns
  • XST_SUCCESS if required peripherals are initialized and configured successfully.
  • XST_FAILURE, otherwise.
Note
None.
u32 DpTxSs_StreamSrc ( u8  VerticalSplit)

This function setup stream source to input DisplayPort TX Subsystem.

Parameters
VerticalSplitspecifies whether to split video frame vertically into two different vertical halves.
  • 1 = Vertically split input frame
  • 0 = No vertically split input frame.
Returns
  • XST_SUCCESS if stream source is configured successfully.
  • XST_FAILURE, otherwise.
Note
None.
int main ( void  )

This is the main function for XDpTxSs SST/MST example.

Parameters
None.
Returns
  • XST_SUCCESS if the MST/SST example passed.
  • XST_FAILURE if the MST/SST example was unsuccessful.
Note
None.
