XDCAM HD XDCAM HD - Versatile, Disc-based HD Recording System The Sony XDCAM HD system is a highly versatile production tool that offers flexible recording functionalities including a choice of video frame rates, interlace or progressive modes, recording data rates, and both HD or SD* formats. *Selectable between 16:9 and 4:3 aspect ratios. HD 1080 Recording using the "MPEG HD" Codec The XDCAM HD products record 1080-line high-definition video using the "MPEG HD" codec that uses the industry-standard MPEG-2 MP@HL compression. The use of this codec, which is based on common MPEG compression, allows compatibility with many other devices such as nonlinear editing systems. Selectable Bit Rates Choosing the highest bit rate of 35 Mb/s results in the highest-quality pictures over a recording time of up to 150 minutes*, while choosing the 18 Mb/s bit rate provides a longer recording time of up to 265 minutes*. *Approximate time in two-channel audio recording mode with the PFD50DLA (50 GB disc). Wide Choice of Video Format - Interlace and Progressive Including Native "23.98P" Mode The XDCAM HD products offer a wide choice of video formats for both frame rates and scanning mode. They include 1080/59.94i, 50i, 29.97P, 25P, and native 23.98P. High-quality Uncompressed Audio Recording In addition to HD video recording, high quality audio is an equally significant feature in the XDCAM HD system. The XDCAM HD products can record four-channel, 16-bit, 48-kHz uncompressed audio.

HD/SD Switchable Recording and Up/Down Conversion Capability The XDCAM HD camcorders and PDW-F75 deck* provide the powerful capability to record in DVCAM™ format with NTSC/PAL and 16:9/4:3 switchable modes, as well as the MPEG HD format. What's more, both the XDCAM HD camcorders and deck incorporate a down-conversion capability that allows material recorded in the MPEG HD format to be converted to SD signals and output via the SD video output connectors (including SD composite and i.LINK™** connectors). This enables users to view the material on an SD monitor or transfer it to other SD-based equipment such as a VTR or editor. The PDW-F75 also boasts an up-conversion capability, which allows material recorded in the DVCAM format to be converted to HD signals and output via its HD-SDI*** or HD analog component connector. These capabilities allow users to easily and flexibly migrate to HD-based operations at their own pace. *The PDW-F75 deck provides DVCAM recording from inputs via the SD-SDI or SD analog composite interfaces, which require the optional PDBK-104. **i.LINK is a Sony trademark used only to designate that a product is equipped with an IEEE1394 connector. Not all products with an i.LINK connector may communicate with each other. Please refer to the documentation that comes with any device having an i.LINK connector for information on compatibility, operating conditions, and proper connection. ***HD-SDI output is only available on the PDW-F75. 4
