Notes:
• Only new circuits (circuits that are not published recently)
are described.
• Figures can deviate slightly from the actual situation, due
to different set executions.
• For a good understanding of the following circuit
descriptions, please use the Wiring, Block (chapter 6) and
Circuit Diagrams (chapter 7). Where necessary, you will
find a separate drawing for clarification.

HDCP, also YPbPr is supported up to 1080i and HDMI can
support up to 1080p (both also support down to and
including 480i).
• The chassis uses a MT5335PGU scaler IC, which
combines a transport de-multiplexer, a high definition
MPEG-2 video decoder, an MPEG2 audio decoder, an
LVDS transmitter, and a NTSC/PAL/SECAM TV decoder
with a 3D comb filter.
• The Scaler board takes care of the video and audio
processing. It uses the MT5335PGU as scaler engine,
which has built-in high resolution and high-quality audio
decoder. It includes the MediaTek 2D MDDi de-interlace
solution to generate very smooth picture quality for
motions. A 3D comb filter added to the TV decoder
recovers great detail for still pictures. The special color
processing technology provides natural, deep colours and
true studio quality graphics.
• The MediaTek MT5335PGU family consists of a backend
decoder and a TV controller and offers high integration for
advanced applications. The MT5335PGU enables a true
single-chip experience. It integrates high-quality HDMI1.3,
high speed VGA ADC, dual-channel LVDS, and USB2.0
receiver.
