Sony HDCAM HDW250 Configuration guide

HD Digital Videocassette Recorder
HDW-250
Preliminary

In support of the many challenges and opportunities inherent in the
transition to DTV systems, Sony has already developed a full range of
HDVS®(High Definition Video Systems)products. A digital HD camcorder,
system cameras, VTRs, switchers, multi-effects, etc., are among the
products now in use with many major broadcast and production
companies, particularly in the USA and Japan. Working in the harsh
world of day-to-day operational use, these products are graphically
demonstrating the leadership that Sony has earned from over 20 years
of research into HD technology.
Joining this Sony HDVS family is the HDW-250, a portable digital HD
VTR that is designed to be used together with the Sony HDC-750A
Multipurpose Portable Camera, strengthening your field recording
capability. With its outstanding portability and long recording time of
124 minutes, it is a valuable enhancement of the Sony HDCAM®product
range, especially as a backup VTR for the Sony HDW-700 Digital HD
Camcorder. The models in this range, which already includes the
HDW-500 Digital HD Editing VTR and HDW-700 Digital HD Camcorder,
are widely acknowledged for their superb picture quality and reliability
- and particularly for the familiar way in which they operate.
This significant technical achievement has already been recognized by
Sony receiving both an Award from the Motion Picture and Television
Engineering Society of Japan, and the Award of Technical Advancement
from the Institute of Image Information and Television Engineers.
The HDW-250 HD VTR inherits all the advantages of the established
DVW-250 Digital BETACAM®Portable VTR, especially its excellent
operability. Multiple inputs and outputs, and powerful interfacing
capabilities, are major features providing the flexibility required for DTV
to coexist with SDTV - which is still the major system for most users.
For improved field operation in limited access situations, a new design
of remote controller,the RM-B150, providescontrol of both VTR and camera.
The HDW-250 is the ideal digital HD portable recorder. It will support
a wide range of applications in your HD production program, from
highly mobile field acquisition to studio and OB vehicle use.

HDCAM format - superb picture quality and 124 min recording time
The State-of-the-art HD recording technology provides 35 mm film-like picture quality and long
recording times that contributes to lower running costs, 124 minutes from an L cassette and 40
minutes from an S cassette
Excellent operability - familiar operation, compact and lightweight
The HDW-250, a rugged, compact digital HD VTR, has the intuitive Betacam-style of operation
familiar to most operators. It shares its excellent portability, robustness and compact size with the
renowned Digital BETACAM portable VTR
Built-in NTSC analog composite down-converter
To maintain an interface with SDTV equipment, still the major system for most users, a
high-quality NTSC analog composite down-converter is built in as standard. It includes an NTSC
image enhancer function.
Standard HD-SDI interface for
simple connections
The built-in HD-SDI (High Definition Serial
Digital Interface, to the SMPTE 292M
standard)provides a convenient, HD base-
band digital interface with other video
equipment via a single coaxial cable.
Multiple inputs and outputs
for wide-ranging applications
To provide the flexibility required for field
recording, editing, and monitoring in DTV
and SDTV systems, the HDW-250 the following inputs and outputs.
•HD-SDI input and output through a single coaxial cable for a smart system connection
•26-pin camera cable interface
•Analog audio 4-channel inputs and outputs(A to D conversion at 20 bits and D to A at 18 bits)
•1125/525 switchable Ref. Sync input and output
•NTSC analog composite output, with on/off switchable character superimposition
•HD analog Y/Pb/Pr component monitoring output, with on/off switchable character superimposition
Remote control with the RM-B150
The HDW-250 can be remotely controlled from the RM-B150, a new remote controller developed
for the HDW Series. A Sony HD
video camera , connected to the
HDW-250 with an HDCZ-Series 26-
pin camera cable, can also be
controlled from the RM-B150. This
unique function is useful where
confirmation playback is required
from the HDW-250 in limited access
situations.
System Configuration
HDW-250 shown

100 meters, camera to recorder
The camera and HDW-250 can be separated by up to 100 meters of cable, either by using HD-SDI
connections or a 26-pin HDCZ Series cable in conjunction with an HDCD-50 HD Signal Distributor.
Low power consumption for longer record time
Thanks to its sophisticated new circuitry, the HDW-250 provides a continuous record time of approximately
100 minutes from one BP-L60A battery.
External battery operation
As well as the internal battery, an external battery can be connected to provide a longer operating time.
As the external battery has priority, there is no interruption when hot-swapping the internal battery,
which contributes to a longer continuous record time.
HDCAM tape
Sony has created a new metal magnetic particle tape,
the HDCAM tape. This has a C/N (Carrier to Noise
Ratio) of 45 dB, to ensure high-integrity digital HD
recording in the field. This HDCAM tape has many new
features, but is in the same price range as Digital
BETACAM tape to keep running costs low.
Field frequency 60/59.94 Hz and effective
scanning line 1080/1035 switchable
Thanks to its advanced design, the HDW-250 is the
ideal digital HD portable VTR for DTV systems.
Switchable field/line scanning frequencies make it
convenient to use for international HD program
exchange convenience.It can also be interfaced with the
SDTV environments that still dominate the broadcast and
video production industries.
