DVCAM Format for Professional Shooting
Environments
DVCAM is Sony's professional version of the
ubiquitous DV format recording component digital
for high quality and a universe of editing
solutions. The camera has iLink, the Sony version
of Firewire (also known as IEEE1394). The DVCAM
format runs the tape at a higher speed than the
consumer DV format, which means more information to
tape every second of recording.
Advanced CCDs and Upgraded DSP
The DSR-PD170 offers both outstanding video and
still image capture. The 3-CCDs have 380,000 pixels
each that deliver over 500 lines of resolution. In
video mode, the digital signal processor (DSP)
outputs a 480 line interlaced signal resulting in
over 500 lines of high quality video. In
still-capture mode, the DSP outputs 480 lines
progressively. With recent technical improvements,
the DSP now works more efficiently, the camera is
more sensitive, and less light is required for
great images.
Optical Image Stabilization
A digital circuit could effectively stop the
subtle hand shaking while holding the camera. But
that would degrade the picture in the long run. The
DSR-PD170 has a system of motors that correct the
angle of the lens hundreds of times per second
eliminating minute variances caused by your hand.
This system works prior to image capture thus does
not affect the quality of your video.

Analog to Digital Converter
Pass-Through
The PD170 can pass through an analog video
signal and output a digital one and visa versa.
Simply put, this eliminates the need for an
outboard A-D/D-A converter box if the digital
signal you need is Firewire (iLink) and the analog
signal is composite or S-video.
Settable Time Code
Like its broadcast brothers, the DSR-PD170 can
be set to start timecode at any time from hours to
seconds. This allows you to effectively name your
cassettes based upon the sequence you shoot them.
Your first tape can start at hour 1, -second tape
hour 2 and so on.
XLR Audio with Phantom Power
You will find 2 XLR inputs for industry standard
professional microphones. Phantom power, a 48-volt
power supply, can be supplied to special
microphones that require such power. The XLRs can
also input line level audio from, as examples, an
audio cassette deck or VCR.
Time and Date Window Burn
Useful in legal and security environments, the
PD170 will, with a menu selection, burn time- down
to seconds- and date onto the tape in a window over
the image.

Comparison of
the PD150 and PD170
|
1. PD170 has a bigger viewfinder (same monitor
with magnifier)
2. PD170 has a precision Hybrid 200.000 pixel
LCD screen (no turning off backlight) and switch
between LCD and viewfinder.
3. PD170 has improved sound quality for manual
recordings. (All hiss problems solved) -6db better
S/N on mic inputs. Due to improved audio process
circuit
4. PD170 has improved CCD with 1 lux low light
(in stead of 2) due to improved CCD and signal
process.
5. Wide angle lens 0.7x and extra lens hood
comes with the package. And Lens hood integrates
lens cap
6. Handle/grip on top is slightly different.
10mm Higher than the PD150. The size is larger in
order to get an improved grip. Also comes with
start/stop button and zoom rocker with 3
speeds.
7. PD170 has playback functions on top
camcorder!
8. PD170 has improved exposure control. Now 24
in stead of 12 steps.
