■ 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. ■ 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.

The actual data transfer rates may vary depending on the nonlinear editing system used. **For connection with third party products using this mode, please contact your nearest Sony office. 7
