DVD-HR77 Playback & other Features
Progressive Scan
Program Navigator
By scanning all 576 lines(PAL) in one pass,
progressive scanning provides high vertical
resolution and flicker free, high density image
output that does not suffer from the loss of
quality during subject movement which is
characteristic of the conventional interlaced
scanning method. 50 Frame/Sec25 Frame/Sec
Recorded programs are shown as thumbnail pictures, and information
such as title, recording dates and times are displayed on menu screen.
User can choose a desired program.
Editing
Simple non linear editing is possible on menu screen without additional editing
system. User can delete part of a program or entire program, and edit program title.

•Front- Micom uPD78F0526 (FIC1, NEC is used to control
Power, VFD Module, MTS Block, KEY Input Matrix etc.
•The SPI (Serial Peripheral Interface port provides a bus
for a serial interface with AV- CODEC MS9411

5. Vi deo I nt er f ace

•U1 (MPEG2 Encoder/Decoder diverges from the 13.5MHz crystal, then generates
VSYNC and HSYNC.
•U1 does RGB encoding, copy guard processing and D/A conversion of 10bit Video
signal converted into analog signal is outputted via amplifer of analog part.
•U1 inputted from pin 131 with 13.5MHz generates HSYNC and VSYNC which are
based on video signal. U1 is synchronous signals with decoded video signal.
•The above signals, which are CVBS (Composite Video Burst
Synchronized ,Y(S_Video ,C(S_Video ,Y(Component /G(Green ,Cr(component /R(Red ,
Cb(component /B(Blue , are selectively outputted 576i(interlaced Video Output ,
576P(progressive Video Output .
•U1 adopts 10bit D/A converter. U1 perform video en- coding as well as copy
protection.
•IC216(HA118827 switch whole the I/O signals of jack block. This switch IC is
controlled by I2C protocol between FIC1(IO front micom .

9. NTSC/ PAL Di gi t al encoder
The NTSC/PAL digital video encoder
(DENC module converts a digital video
data stream into NTSC or PAL composite
or component video output.
The digital input format includes 8- bit
(interleaved or 16- bit YCbCr 4:2:2 video.
 The MS9411 ENCODER output can be in one of the following formats:
- .Baseband composite (M NTSC or (B,D,G,H,I PAL analog video.
- .Separate analog Y/C outputs to support S- video.
- .Separate analog component video RGB or SMPTE YPbPr outputs.
