Mitsubishi V19-V21 Tehnical Manual page 7

When used with consumer Audio Video products it
transfers digital data streams for DTV and Digital Cable
Boxes. This includes MPEG2 HDTV data streams.
When components are 1394 compatible, interconnec-
tion of the units is simplified. Figure 1-1 illustrates how
the 1394 system simplifies interconnection between the
DTV and a D-VCR.
Figure 1-1A shows the connections between a DTV
and D-VCR when components are not 1394 compat-
ible. Six cables are required to transfer analog signals
from one unit to the other. In addition, control of the
VCR would be from an IR Blaster signal or directly
from the D-VCR's Remote.
Figure 1-1B shows a single 1394 cable connection be-
tween a DTV and the D-VCR that are 1394 compliant.
There are two types of 1394 Cables:
• 6 wire – two wires for data transfer, two wires
for timing, and two wires for power.
• 4 wire – two for data transfer and two for
timing.
Figure 1-2 shows an IEEE-1394 4 wire cable, used in
consumer Audio Video. It consists of two pairs of
twisted wires. Each pair is separately shielded, and then
the entire cable is shielded. This minimizes any interac-
tion between conductors. 1394 cables may be up to
40 feet in length.
Home Theater components that are not System 5
or 1394 compatible can usually be controlled through
the TV by one of two methods.
1) Using the corresponding Mitsubishi remote
layer, Cable, VCR, DBS or DVD.
2) Using that component's Remote Control and an
IR Blaster connected to the IR Repeater Jacks.
5C Copy Protection
5C Copy Protection prevents copying restricted sig-
nals. There are three levels of 5C Copy Protection:
1) Unlimited Recording allowed.
