The Versatile DVCAM Recorder For Professional Editing
The DSR-45A* is a DVCAM TM digital videocassette recorder designed for use in both nonlinear editing suites and linear A/B roll-editing
suites as a source feeder 1 . It is ideal for operations ranging from those in small to medium-sized production houses to corporate
institutions and from video journalism to event/wedding videography. Its i.LINK
compatible DV-based editing suites. In addition, analog component connectors allow the unit to accept and transfer high-quality
video and audio. For external control, the DSR-45A comes standard with Control S, RS-422A and RS-232C interfaces. Equipped with
a 2.5-inch 3 type built-in LCD monitor, the DSR-45A displays information including audio level and system status, as well as playback
picture. Offering a wide range of interfaces and professional features, the DSR-45A is a powerful tool for all video professionals.
* In the following text, "DSR-45A" refers to both the DSR-45A (NTSC model) and the DSR-45AP (PAL model).
DVCAM Format for Excellent Picture and
Sound Quality
The DVCAM Format
The DSR-45A uses the DVCAM format, the professional
extension of the worldwide standard DV format. The
DVCAM format uses 8-bit digital component recording
with a 5:1 compression ratio and a sampling rate of 4:1:1
(for NTSC)/4:2:0 (for PAL). The unique compression
algorithm provides excellent picture quality and superb
multi-generation dubbing performance.
Up to Four Independent, High-quality,
Audio Channels
The DSR-45A provides two selectable audio channel
modes; a two-channel mode with 48 kHz/16-bit
recording and a four-channel mode with 32 kHz/12-bit
recording. Thanks to its PCM (Pulse Code Modulation)
digital stereo recording system, the DSR-45A offers
superb digital audio performance with a wide dynamic
1. The DSR-45A is best used as a player/recorder in a nonlinear editing suite. When used in A/B roll editing, the DSR-45A can be used as a source feeder. The DSR-45A cannot perform insert or assemble editing nor does it have
a synchronization capability. 2. i.LINK is a Sony trademark used only to designate that a product is equipped with an IEEE 1394 connector. All products with an i.LINK connector may not communicate with each other. Please

range and an excellent signal-to-noise ratio, comparable
to CD-quality audio.
Playback Compatibility with
the DV (25 Mb/s) Format
The DVCAM format maintains playback compatibility with
the consumer DV format. 4 This compatibility allows the
user to play back DV recorded tapes on the DSR-45A.
Such versatility is quite advantageous to users working
with DV cameras for their great portability and long
recording times.
Dual-size Cassette Mechanism
The DSR-45A has a dual-size cassette mechanism, which
accepts both mini and standard size DVCAM and DV
cassette tapes without any special adaptor. This
innovative feature allows the four different types of
cassette tapes to be used without the cumbersome
process associated with additional mechanical hardware.
Long-duration Recording Capability
DVCAM videocassette tapes come in two sizes: standard
and mini. A maximum recording time of 184 minutes is
possible with a standard size cassette (PDV-184ME),
while the mini cassette (PDVM-40ME) allows up to
40 minutes. Although the tape is relatively narrow,
1/4-inch (6.35 mm), and the cassette compact, these
long recording times are achieved by using Sony
advanced ME (Metal
Evaporated) tape.
TM2 interface allows seamless integration into
Capability of Recording in DV Format
Should you require a longer record time than what is
available with the DVCAM format, the DSR-45A is
capable of recording in the DV format. In this format, a
standard-sized cassette records up to 270 minutes.
Versatile Video and Audio Interfaces
i.LINK Interface
The DSR-45A is equipped with a 4-pin i.LINK (DV)
interface based on the IEEE1394 standard. The i.LINK
interface provides a digital link from the DSR-45A to a
variety of compatible equipment including Sony DVCAM
VTRs and third-party nonlinear editors. Signals including
video, audio, time code, and control can be transferred
through this I/O with virtually no degradation of image or
sound quality. In addition, when the DVCAM cassette with
IC memory is loaded into a DSR-45A, the ClipLink
recorded on the cassette memory can be uploaded to a
nonlinear editing system. 6
Analog Component Input/Output and
S-Video
The DSR-45A provides a full range of analog video
inputs and outputs; component, composite, and S-Video
inputs and outputs are all available. The DSR-45A can
also be used as a signal converter. Component,
composite, and S-Video analog signals can easily be
converted to and from i.Link digital signals.
