The top level tab is shown in the following figure.

Figure 1. Top Level Tab

The parameters on the top level tab are as follows.

Component Name
The component name is set automatically by IP integrator.
Video Interface
This option selects the video interface for the HDMI 2.1 TX Subsystem. The allowable options are AXI4-Stream, Native Video, and Native Video (Vectored DE).
Include HDCP Encryption
This option enables both HDCP 1.4 and 2.3 encryption.
Note: HDCP Encryption options are only configurable if you have a HDCP license; otherwise it is disabled and grayed out from the GUI.
Enable Dynamic HDR Support
This option enables Dynamic HDR support (Section 10.10.2.3 of the HDMI 2.1 specification (https://www.hdmi.org/spec/hdmi2_1)).
Important: External YUV420 Conversion is removed. Optimized AXIS Remapper and YUV 420 Conversion is added inside the subsystem. External Video AXI4S Remapper is not required in designs for 8kp60/10kp60 support. To enable 8kp48, 8kp50, 8kp60/10kp60 YUV420, select Number of pixels per clock as 8. Otherwise, it is recommended to select Number of pixels per clock as 4, which is sufficient to support up to 8k/10kp30.
Important: In Native Video or Native Video (Vectored DE) interface, the IP supports YCbCr 4:2:0. However, you must process YCbCr 4:2:0 Pixel Encoding. See Section 7 in the HDMI 2.0b Specification (http://www.hdmi.org/manufacturer/specification.aspx) or Video Input Stream Interface.
Max bits per component
This option selects the maximum bits per component. The allowable options are, 8, 10, 12 or 16 bits. This parameter is to set the maximum "allowed" bits per component, and the actual bits per component can be set from the software API to a different value. However, the actual bits per component is bounded by the Max bits per component. For example, if the Max bits per component is set to 16, the user can set the actual bits per component from the software API to any of the values, 8, 10, 12 or 16. But if the Max bits per component is set to 8, you can only set the actual bits per component to 8 through the software API.
Number of pixels per clock on Video Interface
This option selects the number of pixels per clock. The allowable options are 4 or 8 pixels per clock in the AXI4-Stream Interface. Native Video or Native Video (Vectored DE) Interface supports only 4 pixels per clock.
Note: IP supports only resolutions that are divisible by 4 (HTotal, HActive, and HBlank). For YUV 420, only video timings that are divisible by 8 are supported.
Number of GT lanes
Fixed to 4 GT lanes.
Hot Plug Detect Active
This option selects the HPD active polarity. The allowable options are High or Low.
