PSTN MODEM
TCP
/IP streams
is delivered
via the PSTN with either real-time
transfer
of
data identified
as G.729A audio to the G.729A decoder,
or to STB memory.
MODEM used in the STB supports
data transmission
rate of 33.6kbps.
4-17.
G.729A
On line audio data is sampled
at 8kHz and delivered
via the MODEM, or the EIA232
port. G.729 decoder
stores the transmitted
data into the RAM and send it again
to L,R channel
output after decoding
this data.

The objective
of IEEE 1394 data port is to transmit
and receive
TS stream among
the devices
and transmit
DVB TS Stream received
from the module to ICAM at data
rate of 25Mbps.
Asynchronous
input/output
data rate between
CPU and IEEE 1394
is 2Mbps and it is realized
through
the host parallel
interface(1284).
Electrical
and mechanical
specifications
of IEEE 1394 are as follows:
4-18-1.
It uses a 68 pin PCMCIA/JEIDA
type edge connector.
4-18-2.
It provides
independent
Transport
Stream input/output
paths.
4-18-3.
It supports
parallel
8-bit communication
and an I2C path for control
of
the module.
4-18-4.
All I/O signals
of its connector
is 3.3V logic level.
