"Exmor" CMOS image sensors, each with
effective pixel count of 2.07 megapixels, that
feature F12 (59.94i)/F13 (50i) sensitivity and 59
dB S/N ratio for shooting high-definition images.
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.
Multi-format support
The unit supports HD recording at 1080/59.94i
and 1080/50i system frequencies. It also supports
recording and playback of SD signals (both
NTSC and PAL), allowing a stepwise transition
from SD to HD systems.
A format conversion function enables up- and
down-conversion between SD and HD. Squeeze,
edge cropping, and letterbox are selectable as the
aspect pattern in up- and down-conversion
between SD and HD.
Note
It is not possible to combine material recorded at
different system frequencies on a single disc (see page
53).
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.
• 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.
It is also capable of recording and playback in the
MPEG IMX 50/40/30 Mbps and DVCAM 25
Mbps formats.
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
• Selectable video input connectors: The unit is
designed to support recording in every type of
environment, including reporting by pool
coverage teams. The optional CBK-HD01 HD/
SD SDI Input Board or CBK-SC02 Analog
Composite Input Board can be installed to
