9.6.1. The HDMI board is capable of Interlace output or Progressive
Scan. Upon the sensing of HDMI connection, for interlace
output,it will take the upscaled 20 bit YCbCr from the Faroudja
and output to HDMI-compatible receiver.
When YUV is connected, Video DAC will take the 8bit ITU656
digital video from Chrysalis to output to YUV for progressive
output or output to Analog Board for further processing.
The Control of Routing of Digital Video to either Progressive
YUV output or HDMI output is control by I2C Control lines.
9.6.2. The HDMI board functions is based on the Columbus,
Faroudja,Video DAC and HDMI Transmitter (Tx)
Integrated Chips as mentioned below:
T6TU5XG[7400]Columbus which accept 8-bit ITU656 digital
video signal and functions as below:
•
Combination of a 2D Combinational fi lter for both PAL and
NTSC
•
Spatial /temporal noise reduction system for both colour
and luminance signals
Faroudja FLI2310[7100] is a highly integrated digital video
format converters for DTV and DVD which functions as
belows:
•
Picture Enhancement
•
Motion Adaptive Noise Reduction – Improves picture
quality for off-air material.
•
Cross Color Suppressor (CCS) – Removes cross
color artifacts in composite video signals due to poor Y/C
separation in standard 2-D video decoders, eliminating
the need for expensive 3-D video decoders.
•
Adaptive Deinterlacing used for proper de-interlacing of
3:2 and 2:2 pulldown
•
High Quality Fully Programmable Two Dimensional Scaler

Video DAC ADV7320KSTZ[7253] is a multi-format 216 MHz
Video Encoder with 6 NSV12-bit DACS which functions as
belows:
•
Possess a separate 8/10/16/20-Bit wide input ports which
accept data in high defi nition and/or standard defi nition
video format.
•
For all standards,external horizontal, vertical and blanking
signals or EAV/SAV timing codes control the insertion of
appropriate synchronisation signals into the the digital
data stream and therefore the output signal.
HDMI Transmitter SII9030CTU [7304] is a high-resolution
panellink cinema transmitter that support the HDMI 1.1
specifi cations which functions as belows:
•
Sending protected digital audio and video content to
HDMI receiver.
•
Built in backward compatibility with DVI 1.0 allows HDMI
to connect to any DVI 1.0 display
•
HDMI Transmitter SIl9030 support up to 4x I2S and
SPDIF but at the moment only 1x I2S and SPDIF are
used.
*HDCP Security keys are pre-programmed, providing
highest level of security, simplifying manufacturing.

Infrared (IR) Blaster Board
The IR Blaster consists of a slave μp TMP86PM74AFG[7100]
to be controlled by Digital Board Microprocessor to wake-up
external Set-top satellite box via G-Link for timed Recordings.
The tuner and GuidePlus programme of the external Set-
top box will be activated when IR blaster sends signal for
activation.
9.8.
Digital Terrestial Tuner Module (DTTM)
The DTTM module received DVB-T signal from Digital Tuner
and outputs to the DB AIO Connector [1403] for Audio signal
processing and DB-VIO-CONN [1501], AB-VIO-CONN [1502]
for video processing.
