The following figure shows the top level tab.
Figure 1. Top Level Tab
The parameters on the top level tab are as follows.
- Component Name
- Set automatically by the IP integrator.
- Video Interface
- Selects the video
interface for the HDMI 2.1 TX Subsystem. Supported
options:
- AXI4-Stream
- Native Video
- Native Video (Vectored DE)
- Include HDCP Encryption
- Enables both HDCP 1.4 and 2.3 encryption.Note: You can configure the HDCP Encryption options only if you have a HDCP license; otherwise, the GUI disables and grays them out.
- HDMI 2.x Mode
- Selects the HDMI 2.x Mode for
the HDMI 2.1 TX Subsystem. Supported options:
- HDMI 2.1 (FRL + TMDS)
- HDMI 2.1 (TMDS ONLY)
- Enable Dynamic HDR Support
- Enables Dynamic HDR support (HDMI 2.1 specification section 10.10.2.3 (https://www.hdmi.org/spec/hdmi2_1)).
- DSC Enable
- 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. Refer to Section 7 in the HDMI 2.0b Specification (https://www.hdmi.org/spec/index) or AXI4-Stream Video Input Stream Interface.
- Max bits per component
- Selects the maximum bits per component. Supported options: 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
- Selects the number of
pixels per clock. Supported options: 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: The 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
- Selects the HPD active polarity. Supported options: High or Low.
