The main features of the DVD interface are :
- DVD, VCD and CD-DA compatible,
- hardware sector filtering,
- subcode error correction for CD-DA,
- integrated CSS decryption,
- integrated track buffer support,
- DMA engine to ST20 memory.
In DVB-DSS mode, DVB-DSS transport stream is
input through a serial interface. The STi5505 ex-
tracts and descrambles Packet Elementary
Streams belonging to one user selected program
to be decoded and presented.
The main features of the DVB-DSS interface are :
- descrambling (transport packet and packet ele-
mentary streams in DVB mode, transport packet
in DSS mode ; up to 32 streams descrambling),
- PID and section filtering,
- clock recovery,
- DMA engine.
In DVB-DSS mode, a high speed digital interface
allows to transfer packets between the Set Top Box
and external units, either for recording or playback
purposes. This interface provides also full support
for an external IEEE1394 connection.
I.9 - Integrated Peripherals
Several peripherals generally used in DVD players
or DVD-DVB combos have been integrated into the
STi5505.
They are :
- two UARTs to interface remote control receivers,
DVD front end, modem ...,
- one I
2
C controller to interface serial memories,
remote control receivers, microcontrollers...,
- 2 SmartCard interfaces (ISO7816-3) for DVB-
DSS conditionnal access, pay per view ...,
- PWM/timer module for control of system clock,
- 34 programmable I/O pins,
- OS Link interface,
- JTAG with boundary scan for debug.
