With the i.LINK system, there are 64 lines (0 to 63) for sending video and sounds between devices. These lines reserve ROOT when it is

being used between devices, set it so that it cannot be used by other devices. This method is called P to P (Point to Point) connection for one
device to communicate with another device. The LINC (Logical INterface Connection) described in the instruction manual corresponds to
this P to P connection.

Sending data in the no-LINC state is called Broadcast communication. In Sony DV camcorders, the 63rd channel of the transfer line is

used for outputting signals of the DV camcorder.

Even when audio signals are output in the no-LINC state in Sony audio devices, broadcast communication will be performed.

(Example: STR-LSA1 Tuner output, etc.)

When sending music data with the input device selected amongst LISSA series devices and LISSA series devices, the data will always be

LINCed and output. However, when not LINCed from other devices, the audio signals will be broadcast-output.

Only one signal can be used by channels. When two DV camcorders are set to the playback state and broadcast communication is

performed, the signal which started playback later will dominate the channel.

When LISSA series devices which are not LINCed with other devices start playback, the signals of the DV camcorder will be blocked by

LISSA series’ signal. In this case, the DV camcorder will be stopped once, and when playback is started again, the 63 channel will be
dominated by DV camcorder again.
