• IT (Interline Transfer)
image sensors with 2.2 million pixels, for full
HD resolution (1920 × 1080)
• "PowerHAD FX" CCDs, featuring a signal
processing ASIC with 16-bit A/D converters
These new image sensor technologies enable the
capture of very high-quality images, with F10
(59.94i) and F11 (50i) sensitivity and an SN ratio
1)
of 64 dB.
1) With noise suppression on (off value is 60 dB)
Noise suppression uses proprietary Sony signal
processing technology to suppress noise in high-
frequency regions.
Mechanisms for high reliability
A new duct cooling system prevents overheating
inside the unit and on its surfaces, for greater
reliability in high-temperature environments.
Reliability is also enhanced by the drip-proof
design.
Recording can continue even when the unit is
subjected to jarring shocks, because data is stored
in shockproof memory before being recorded to
the media. Reliable recording is ensured by a
recording verification function, similar to the
confidence playback function of tape recorders,
qualifying the unit for use in demanding
broadcast applications.
Recording of more than 90 minutes of
high-quality video and audio data
• Signals captured by the full-HD (1920 × 1080)
image sensors are recorded in MPEG HD422
1)
format for consistently high image quality.
• The unit supports recording of four audio
3)
channels sampled at 24 bits for high quality.

2)
• Dual-layer Professional discs can record about
95 minutes of high-quality video and audio
data.
The generous recording times and the high-
quality of the recorded video and audio allow this
unit to meet the most stringent requirements of
production teams in a wide range of genres, from
news gathering through digital cinema and
program production.
1) The MPEG-2 422P@HL codec performs 4:2:2
sampling and records at a video bit rate of 50 Mbps.
2) Image compression uses the MPEG-2 Long GOP
system.
3) The PDW-HD1500 supports recording of up to eight
channels in MPEG HD422 format.
Format compatibility with earlier models
The unit is capable of recording in the MPEG-2
MP@HL 35/25 Mbps formats used by earlier
XDCAM HD devices. These formats offer longer
recording times than the MPEG-2 422P@HL 50
Mbps format.
Rich selection of interfaces
• HDSDI and SDSDI output connectors: Allow
free combination of HDSDI and SDSDI signals.
Timecode and other text data can be
superimposed on signals from one of the two
interfaces.
• Composite signal output connector
• Video input connector: Supports HD SDI signal
input, enabling compilation in various
environments, such as collaborative news
gathering.
• Gen-lock input connector: Enables
synchronized operation of multiple units, with
synchronization possible to either VBS or HD-
Y signals.
• Audio input connectors: Supports AES/EBU
signal input, in addition to microphone input,
+48 V microphone input, and line input.
• Timecode input and output connectors
• Network connector: Enable transfer of MXF-
format files.
• USB connector: Enables use of a Windows
USB keyboard or mouse. You can also connect
a USB flash drive to record proxy data or load
