About battery life
• Battery capacity decreases over time and
through repeated use. If decreased usage time
between charges becomes significant, it is
probably time to replace it with a new one.
• Each battery's life is governed by storage,
operating and environmental conditions.

About i.LINK

The HDV/DV Interface on this unit is an
i.LINK-compliant Interface. This section
describes the i.LINK standard and its
features.
What is i.LINK?
i.LINK is a digital serial interface for
transferring digital video, digital audio, and
other data to other i.LINK-compatible
devices. You can also control other devices
using the i.LINK.
i.LINK-compatible devices can be
connected using an i.LINK cable. Possible
applications are operations and data
transactions with various digital AV
devices.
When two or more i.LINK-compatible
devices are daisy-chained with the unit,
operation becomes possible from any
device in the chain. Note that operation
method may vary, or data transactions may
not be possible, depending on specifications
and characteristics of the connected
devices.
b Notes
• Normally, only one device can be connected to
this unit with an i.LINK cable. When
connecting this unit to an HDV/DV compatible
device having two or more
Interfaces, refer to the operating instructions of
the device to be connected.
z Tips
• i.LINK is a more familiar term for the
IEEE1394 data transport bus proposed by Sony,
and is a trademark approved by many
corporations.

HDV/DV
• IEEE1394 is an international standard
standardized by the Institute of Electrical and
Electronics Engineers.
About the i.LINK Baud rate
i.LINK's maximum baud rate varies
according to the device. There are 3 types.
S100 (approx. 100Mbps*)
S200 (approx. 200Mbps)
S400 (approx. 400Mbps)
The baud rate is listed under
"Specifications" in the operating
instructions of each piece of equipment. It
is also indicated near the i.LINK interface
on some devices.
The baud rate may differ from the indicated
value when the unit is connected to a device
with a different maximum baud rate.
* What is Mbps?
Mbps stands for "megabits per second," or
the amount of data that can be sent or
received in one second. For example, a
baud rate of 100 Mbps means that 100
megabits of data can be sent in one second.
To use i.LINK functions on this unit
For details on how to dub when this unit is
connected to other video devices having an
i.LINK Interface, see page 65.
This unit can also be connected to other
i.LINK-compatible devices made by Sony
(e.g. a VAIO series personal computer) as
well as to video devices.
Some i.LINK compatible video devices,
such as Digital Televisions, DVD,
MICROMV or HDV recorders/players are
not compatible with this unit. Before
connecting to other devices, be sure to
confirm whether the device is compatible
with an HDV/DV device or not. For details
on precautions and compatible application
software, refer also to the operating
instructions for the device to be connected.
