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 RX 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)).
- DSC Enable
- This option enables DSC passthrough support.
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 (https://www.hdmi.org/spec/index) or AXI4-Stream Video Output 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, you 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.
- EDID RAM size
- The allowable options are, 256, 512, 1024, or 4096.
- Cable Detect Active
- This option selects the Cable Detect active polarity. The allowable options are High or Low.
