1 A/V Circuit BLOCK Diagram
1) PC Mode
PC inputs, R, G, B , , and V signals, are entered through D-S ub 15pin
(DSUB1). They are en tered into the DTV/PC sele ction switch, B A7657
(U30). When PC is se lected in MCU, the signals are entered into the AD
converter, AD9883 (U21).
In AD9883, the signals are converted into 24 bits and entered into scaler
gm6015.
BA7657 selec ts PC when pin16 is high and selects DTV when pin 16 is low.
AD9883 is controlled using the SDA/SCL line of pin 57/56.
PC input resolution is fh: 30~61k and fv: 56~75 z, and the maximum
resolution is 1024x768 at 75 z.
If the resolution is above the specifications, an out of range m essage is
displayed on the upper left hand corner of the screen. owever, even if the
resolution is within the specified range, if the input timing is different from
the timing indicated on the manual, not supporded video, a message
can be displayed. The Geometry Adjust function, which is used to adjust the
picture position and size, should be carried out in the Windows desktop screen h.
or full cross hatc The DTV signals, 480p, 720p, and 1080i, from the set-top box
with a D-Sub out port, can be received through the D-Sub port and displayed
in the PC mode.

2) DTV Mode
DTV signals are entered as Y, P b(Cb), and Pr(Cr) component signals,
separated into Y, Cb, Cr and entered to BA7 657.
If pin 16 is low, DTV signals are entered into ADC9883.
In the AD9883, like the PC signals, the DTV signals are converted to 24 bits
and entered into scalar gm6015.
DTV signa l is composed of 480p (50/60 z) for SD, 720p (50/60 z) for D,
and 1080i (50/ 60 z). If the video signal, 480i component (DVD component
output), is entered, the screen will not display properly. Also,
because synchronization signal
if the connections are incorrect, it will not operate properly
is in Y singal color Data is in Cr/Cb
3) S-Video
S-Video signals are entered as Y/ C signals, which is composed of Luminance
color signals. The NT SC and PAL/SECAM are automatically detected by the
video decoders, main VPC3230 and sub VPX3226, and converted to Y (8bits)
and UV (8bits) and sent to the Scaler IC, gm6015
S-Video input and composite video input share a single audio jack.
Therefore, while the pictures for the two inputs can be viewed at the same
time, only one of the sounds can be heard.
4) Video
Video signal is a composite signal that combines the Luminance(Y) and color
(C ROMA) .
It is entered through the main VPC3230 and sub VPX3226,and sent to the sealer IC, gm6015.
IC, gm6015.

Supported.
CVBS Signal is recongnized by DC Level at PIN #8 in Scant and RGB Signal is
recognized by DC Level at Pin #16
video input is displayed on the main screen,

Audio input signal for PC, DT V, and CVBS modes is entered into the
audio processor IC(MSP3410 or MSP3420), and audio input signal for
VIDEO/S-VIDEO, and SCART CVBS modes entered into the audio
processor.
scart
As in other chips, the audio processor (MSP3410/20) uses the SCL and SDA
line to control volume, and left/right balance and mono/stereo and SRS on/off,
and Sound effect.
The L/R audio signal sent by MSP3410/20 is amplified in the amplifier, TDA1517(U3)
and sent to the speaker.
TDA1517 support 5W(based on impedance 4) of output for each L/R.
