14.4.2.6.1
DisplayPort Auxiliary Channel
A bidirectional AC coupled AUX channel interface replaces the I
2
C for EDID read, link 
management and device control. I
2
C-to-Aux bridges are required to connect legacy 
display devices.
14.4.2.6.2
Hot-Plug Detect (HPD)
The SoC supports HPD for Hot-Plug sink events on the HDMI and DisplayPort interfaces.
14.4.2.6.3
Integrated Audio over HDMI and DisplayPort
 SoC can support two audio streams on DP/HDMI ports. Each stream can be 
programmable to either DDI port. HDMI/DP audio streams can be sent with video 
streams as follows.
LPE mode: In this mode the uncompressed or compressed audio sample buffers are 
generated either by OS the audio stack or by audio Lower Power Engine (LPE) and 
stored in system memory.The display controller fetches audio samples from these 
buffers, forms an SPDIF frame with VUCP and preamble (if needed), then sends out 
with video packets.
14.4.2.6.4
High-Bandwidth Digital Content Protection (HDCP)
HDCP is the technology for protecting high definition content against unauthorized copy 
or unreceptive between a source (computer, digital set top boxes, etc.) and the sink 
(panels, monitor, and TV). The SoC supports HDCP 1.4 for content protection over 
wired displays (HDMI, DisplayPort and Embedded DisplayPort).

3D Graphics and Video
The SoC implements a derivative of the Generation 7 graphics engine which consists of 
rendering engine and bit stream encoder/decoder engine. The rendering engine is used 
for 3D rendering, media compositing and video encoding. The Graphics engine is built 
around four execution units (EUs).
