High-resolution File Transfer Over a Network
Another stunning feature that innovates current workflows is
the capability to transfer high-resolution material over a
standard network. Clips recorded on Professional Disc
media can be sent and received over a standard network
through a LAN port on the decks or camcorders*, allowing
seamless exchange of material among any networked
devices installed all over the world.
The transfer can be performed by a simple FTP operation
using Microsoft Internet Explorer or common FTP client
software. The supplied PDZ-1 software can also be used to
perform file transfers very easily. For advanced operations,
the Partial FTP Transfer function allows only the clips selected
in a Clip List to be transferred over the network.
This network capability makes it possible to send footage
from the field to the studio immediately after the shoot, or
easily share material among production staff at multiple
locations, without the lead time of delivering tapes or
replying on costly satellite transmissions.
The file-based transfer provides another great benefit: it
enables operators to dub material without any generation
loss. File operations such as Partial Transfer and Disc Copy
can also be performed via the i.LINK (File Access Mode)
interface, with the same benefit of no generation loss.
*XDCAM camcorders require an optional Ethernet (100Base-TX) Adaptor
(CBK-NC01).

High-Speed Data Transfer – the
Foundation of Workflow Innovation
A large part of the appeal of these Sony XDCAM
products is their high-speed data transfer capability,
allowing you to transfer data to other equipment at
speeds several data rates faster than real time.
This is possible because XDCAM products provide a
range of high-speed interfaces and because,
by nature, the Professional Disc offers the flexibility to
read data at different speeds.
For low-resolution Proxy AV Data, a maximum transfer
speed of an amazing 30 times* for field unit and
50 times* for studio unit faster than real time is
achieved, while for high-resolution (MPEG IMX and
DVCAM) material, the maximum transfer speed is at
5-times* speed for DVCAM signals and 2.5-times* speed
for MPEG IMX signals.
*These are the approximate figures when using the PDW-1500 deck to
transfer data over Gigabit Ethernet. The actual transfer rates may vary.

Power of Proxy Data – Highly Streamlined
Workflows
At the same time as recording its high-resolution video and
audio data, XDCAM HD products also record a
low-resolution version of this AV data on the same disc.
Called “Proxy Data”, this is much smaller in size than the
high-resolution data (1.5 Mb/s for video and 0.5 Mb/s for
audio), and its format is identical to the HD version of the
XDCAM products. Because of its lower resolution,
Proxy Data can be transferred to a standard PC at an
amazingly high speed, and easily browsed and edited using
the PDZ-1 Proxy Browsing Software (or other compatible
software offered by many industry-leading manufacturers).
What’s more, with the PDZ-1 software, it can be converted
to the popular ASF format for playback on Windows Media
Player, providing dramatic improvements in production
workflows. Proxy Data can also be viewed directly on a PC
without data transfer using an i.LINK (File Access Mode) or
USB connection, and can even be sent over a standard
Ethernet network.
The overall flexibility of Proxy Data means that it can be
used for a variety of applications, such as immediate
logging on location, off-line editing, daily rushes of shooting
on location, client approval, and more.
