Note 1: (Pin 8 usage)

On many TV's taking pin 8 high will auto select the SCART input. With a voltage range of 4.5V to

7.0V

a compatible set will select AV input in 16x9 mode. With a voltage range of 9.5v to 12.0v

the set will select AV input in 4x3 mode.

It has come to my attention that certain newer sets (notably those containing Sony CXA2069A
chipset)

implement a third intermediate switching level. Details are sketchy,

but it would appear to select a letterbox format rather than full 4:3 or full 16:9.

Note 2 :
On some devices pin 16 is used to select between composite or RGB input modes using the
same SCART.
With a voltage of 1-3V DC (with respect to pin 18) RGBS input mode is selected.

The switching signal needs to be able to source upto 20mA.

With a voltage range of 0-0.4V composite mode is selected

Scart supports CVBS Signals , RGB(Full-Scart) and Audio Right Left ,

and Y-C Mode Signals is not Supported.

7.3 HDMI (High-Definition Multimedia Interface)

7.3.1 Overview

-HDMI system architecture is defined to consist of Sources and Sinks.
A given device may have one or more HDMI inputs and one or more HDMI outputs.
Each HDMI input on these devices shall follow all of the rules for an HDMI Sink
and each HDMI output shall follow all of the rules for an HDMI Source.

- As shown in Figure 12-1 HDMI Block Diagram the HDMI cable and connectors
carry 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 channel. The DDC is used for configuration and status
exchange between a single Source and a single Sink.
The optional CEC protocol provides high-level control functions between
all of the various audiovisual products in a user’s environment.

12-1 HDMI Block Diagram

- Audio, video and auxiliary 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
as a frequency reference for data recovery on the three TMDS data channels.

- Video data is carried as a series of 24-bit pixels on the three TMDS data channels.
TMDS encoding converts the 8 bits per channel into the 10 bit DC-balanced, transition
minimized
sequence which is then transmitted serially across the pair at a rate of 10 bits per pixel
clock period.

- Video pixel rates can range from 25MHz to 165MHz. Video formats with rates below
25MHz
can be transmitted using a pixel-repetition scheme. The video pixels can be encoded in
either RGB,

BCR 4:4:4 or YCBCR 4:2:2 formats. In all three cases, up to 24 bits per pixel can be

YC
transferred.

- Basic audio functionality consists of a single IEC 60958 audio stream at sample rates of
32kHz, 44.1kHz
or 48kHz. This can accommodate any normal stereo stream. Optionally, HDMI can carry a
single such

--21--

stream at sample rates up to 192KHz or from two to four such streams (3 to 8 audio
channels) at sample
rates up to 96KHz. HDMI can also carry IEC 61937 compressed (e.g. surround-sound)
stream at sample
rates up to 192kHz.

- The DDC is used by the Source to read the Sink’s Enhanced Extended Display
Identification Data
(E-EDID) in order to discover the Sink.s configuration and/or capabilities.

7.3.2 Connectors and Cables

- A device.s external HDMI connection shall be presented via one of the two specified
HDMI connectors,
Type A or Type B. This connector can be attached directly to the device or can be
attached via a cable
adapter that is shipped with the device.

- The Type A connector carries all required HDMI signals, including a single TMDS link.
The Type B
connector is slightly larger and carries a second TMDS link, which is necessary to support
very high-
resolution computer displays requiring dual link bandwidth. A passive cable adapter
between Type A and
Type B connectors is specified.
