R47/R51/C83 send to U16 and output from P17.
Part VI HDMI EDID Introduction
Extended display identification data (EDID) is a data structure provided by a
computer display to describe its capabilities to a graphics card. It is what enables
a modern personal computer to know what kind of monitor is connected. EDID is defined
by a standard published by the Video Electronics Standards Association (VESA). The
EDID includes manufacturer name, product type, phosphor or filter type, timings
supported by the display, display size, luminance data and (for digital displays
only) pixel mapping data.
The channel for transmitting the EDID from the display to the graphics card is usually
the I2C bus. The combination of EDID and I²C is called the Display Data Channel version
2, or DDC2. The 2 distinguishes it from VESA's original DDC, which used a different
serial format.
Before DDC and EDID were defined, there was no standard way for a graphics card to
know what kind of display device it was connected to. Some VGA connectors in personal
computers provided a basic form of identification by connecting one, two or three
pins to ground, but this coding was not standardized.
The EDID is often stored in the monitor in a memory device called a serial PROM
(programmable read-only memory) or EEPROM (electrically erasable PROM) that is
compatible with the I²C bus.
VGA EDID OR DDC
PART VII HDCP Section
High-bandwidth Digital Content Protection (HDCP) is a form of Digital Rights
Management (DRM) developed by Intel Corporation to control digital audio and video
content as it travels across Digital Visual Interface (DVI) or High-Definition
Multimedia Interface (HDMI) connections. The specification is proprietary, and
creating an implementation of HDCP requires a license .HDCP is licensed by Digital
Content Protection, a subsidiary of Intel. In addition to paying fees, licensees
agree to limit the capabilities of their products. For example, high-definition
digital video content must be restricted to DVD quality on non-HDCP compliant video
outputs when requested by the source. DVD-Audio content is restricted to DAT quality
on non-HDCP digital audio outputs (analog audio outputs have no quality limits).
Licensees cannot allow their devices to make copies of content, and must design their
products in ways that "effectively frustrate attempts to defeat the content
protection requirements."
Each HDCP capable device has a unique set of keys; there are 40 keys, each 56 bits
long. These keys are confidential and failure to keep them secret may be seen as
a violation of the license agreement. For each set of keys a special key called a
KSV (Key Selection Vector) is created. Each KSV has exactly 20 bits set to 0 and
20 bits set to 1.
During the authentication process, both parties exchange their KSVs. Then
each device adds (without overflow) its own secret keys together according
to a KSV received from another device. If a particular bit in the vector
is set to 1, then the corresponding secret key is used in the addition,
otherwise it is ignored. Keys and KSVs are generated in such a way that
during this process both devices get the same 56 bit number as a result.
That number is later used in the encryption process.As result that, this
chassis adopts 24C04 to storage KSV and license makes digital signal
resource output.
PART VIII EEPROM for Software
It adopts Winbond company’s W25X40 flash which has 4M-bit/526 bytes and 2048pages.It is
used for storage the main system software. The devices operate on a single 2.7V to 3.6V power
supply with current consumption as low as 5mA active and 1uA for power-down.。
EEPROM for User Information
2
It adopts I
C compatible electrically erasable programmable memory (EEPROM) devices are
organized as 4096x8 bits(32k).This is a two-wire series interface that uses a bi-directional data bus
and serial clock. It is used for storage user’s information, such as channel search and timer on and
off, and picture standard and other information what user’s easy to change by local key board and
remote control.
PART IX Panel ON/OFF Control Section
While the TV is turn on, the TV is standby situation. While command turn on is send out, 5v
voltage will through regulator and equal get 3.3V voltage or 1.8V voltage supply for U8. After
reset and crystal Y1 working, the main system software will be loaded, the panel –ON/OFF
command will be sent out, makes the dual-MOSFET U3 turn on and send 5V/12V/3.3V voltage to
the panel.
The following figure is showing the power sequence and control signal timing.

Description:While the power cord plug in, the TV is in
standby situation,power supply unit provide 5Vstb 200mA for
load.There is no 12v amplifier power supply and 24V
inverter voltage supply. The 5Vstb through D7 and regulator
U5 get 3.3VA supply for IC (MST19E),the another path of
circuit is 5Vstb through regulator U6 get 3.3V then
regulated by U7(regulator) get 1.8V supply for
U8(MST19E),drive the LED lighting,and standby circuitry
working,and CPU controlling,reset circuitry,crystal.So that
it makes the CPU can receive and send kinds of command.
while there is turn on command(low level) send out from
Pin150 of U8(MST19E),power supply unit provide 12V and 24V
voltage.12V voltage supply for U1/U2,change to 5V voltage,
regulate by U6, change to 3.3V supply for U8 others
parties. 24V voltage supply for inverter board of Panel.
