channel audio data and all standard and high-definition consumer electronics video 
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 
 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.
The SoC HDMI interface is designed as per the High-Definition Multimedia Interface 
Specification 1.4. The SoC supports High-Definition Multimedia Interface Compliance 
Test Specification 1.4.
14.4.2.3.1
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.
14.4.2.4
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
