INTRODUCTION
- Digital/Analog broadcasting recorder/receiver [HD/SD PRESONAL VIDEO RECORDER & RECEIVER] or
PVR(Personal Video Recorder)-STB(Set-Top Box) receives the ground wave HD Digital broadcasting pro-
gram /Analog NTSC or Cable broadcasting program and saves a video or audio signal at a HDD with a spe-
cific form or offers related additional services.
- Configuration
The CUP is the IBM PPC405GP of the PowerPC series supporting PCI Bus I/F for PVR, and the tuner
receives a digital ground wave and transfers it as a TP signal, transmitting the NTSC signal of the ground
wave/the cable signal and transferring the audio signal to the SIF.
The MPEG Decoder uses the HD-II supporting MP@HL built with the AC-3 Decoder.
The PVR section transforms the TP data of a digital TV signal and an analog audio/video signal into the TP
by using the MPEG-II Encoder and saves only the necessary one at the HDD via the IDE I/F Chip.
Overall configuration
- System section
CPU, Main Memory, MPEG-II Decoder, Flash Memory, and System CPLD.
- MPEG Video/Audio Decoder section
HD-2, Memory, PLL IC, Audio Processor, Audio ADC, and so on.
- PVR section
TPN-II performing PCI I/F and TP De-Mux, Memory, MPEG-II Encoder, IDE I/F Chip, and 120GB HDD.
- Video/Audio input section
CVBS Decoder, and Audio processor
-1394 section
1394 1-Chip supporting D-VHS and MV Camcoder.
- Tuner
It can receive a signal from ATSC/NTSC/Cable, and send a signal from the ATSC as TP, an analog video sig-
nal as NTSC, and an audio signal as SIF.
- Front section
It is located at the front receiving various key inputs from users and displaying the status of a set-top box at
the VFD.
- Power section
It supplies a DC power to Main Digital Board, Front Board, and HDD with the input of AC 110V.
