HDMI 1.4/2.0 TX Subsystem

Designing with the Subsystem

Therefore, a remapping feature is added to HDMI 1.4/2.0 Transmitter Subsystem to convert 

HDMI native video into AXI4-Stream video.

Note:

For RGB/YUV444/YUV422 formats, video data is directly mapped from AXI4-Stream to Native 

Video interface without any line buffer. Therefore, 

Figure 3-2

 to 

Figure 3-5

 represent the data 

interface for both AXI4 Stream and Native Video. The control signals are omitted in the figures.

The subsystem provides full flexibility to construct a system using the configuration 

parameters, maximum bits per component and number of pixels per clock. Set these 

parameters so that the video clock and link clock are supported by the targeted device. For 

example, when dual pixels per clock is selected, the AXI4-Stream video need to run at 

higher clock rate comparing with quad pixels per clock design. In this case, it is more 

difficult for the system to meeting timing requirements. Therefore the quad pixels per clock 

data mapping is recommended for design intended to send higher video resolutions, for 

example, 4kp60 video. 

Some video resolutions (for example, 720p60) have horizontal timing parameters (1650) 

which are not a multiple of 4. In this case the dual pixels per clock data mapping must be 

chosen.

For more information on the video AXI4-Stream interface and video data format, see the 

AXI4-Stream Video IP and System Design Guide

 (UG934) 

[Ref 14]

.

Interlaced Video

The HDMI 1.4/2.0 Transmitter Subsystem supports both AXI4-Stream Video and Native 

Video interface. 

• When 

AXI4-Stream

 is selected, an AXI4-Stream to Video Out core is used to support 

the HDMI 1.4/2.0 TX Subsystem. Because the AXI4-Stream carries only active video 

data, the AXI4-Stream to Video Out core takes input from an AXI4-Stream slave 

interface and converts it into a Native Video stream, which is then fed to the HDMI TX 

core.
