formats. HDMI display interface connecting the SoC and display devices utilizes
transition minimized differential signaling (TMDS) to carry audiovisual information
through the same HDMI cable.
HDMI includes three separate communications channels: TMDS, DDC, and the optional
CEC (consumer electronics control) (not supported by the SoC). As shown in
CEC (consumer electronics control) (not supported by the SoC). As shown in
the HDMI cable carries four differential pairs that make up the TMDS data
and clock channels. These channels are used to carry video, audio, and auxiliary data.
In addition, HDMI carries a VESA DDC. The DDC is used by an HDMI Source to
determine the capabilities and characteristics of the sink.

Audio, video and auxiliary (control/status) data is transmitted across the three TMDS
data channels. The video pixel clock is transmitted on the TMDS clock channel and is
used by the receiver for data recovery on the three data channels. The digital display
data signals driven natively through the SoC are AC coupled and needs level shifting
to convert the AC coupled signals to the HDMI compliant digital signals.

Stereoscopic Support on HDMI
SoC display supports HDMI 1.4 3D video formats. If the HDMI panel is detected to
support 3D video format then the SW driver will program Pipe2dB for the correct pipe
timing parameters.

The left and right frames can be loaded from independent frame buffers in the main
memory. Depending on the input S3D format, the display controller can be enabled do
perform frame repositioning, image scaling, line interleaving.

Digital Video Interface (DVI)
The Digital Ports can be configured to drive DVI-D. DVI uses TMDS for transmitting
data from the transmitter to the receiver which is similar to the HDMI protocol but
without the audio and CEC. Refer to the HDMI section for more information on the
data from the transmitter to the receiver which is similar to the HDMI protocol but
without the audio and CEC. Refer to the HDMI section for more information on the
