VIDEO SETUP
6.10.1.
Input Format
The HDMI Tx core of the
digital core via a 36-bit wide bus and four synchronization signals:
the pixel clock, the data enable, and the horizontal and vertical synchronization signals. The HDMI Tx core always receives the video data in a
4:4:4 and SDR format from the VSP core.
It is possible to send YCrCb 4:2:2 data from the TMDS RX directly to the HDMI Tx. In which case register 0xEC15 must be set appropriately in
the Tx main map.

Video Mode Detection
The video mode detection feature can inform the user of the CEA-861 defined Video Identification Code (VIC) of the video being input to the
Tx core, as well as some additional formats. If a CEA 861 format is detected, the VIC is contained in
. Some additional non
CEA 861 formats are contained in
For some standards for which the VIC cannot be detected, the user needs to configure the following registers:
•
The aspect ratio (set via the
bit) is used to distinguish between CEA-861 video timing codes where the aspect ratio is the
only difference
•
For 240p and 288p modes, the number of total lines can be selected in the
field
•
The VIC detected is also affected by the pixel repetition (see Section
for more details)
