Chapter 1 Overview
With an HD-SD converter board installed, the unit can
output both D1 SDI and analog composite signals.
Besides audio data is output as digital data multiplexed
with the HD SDI signal, it is also output via an AES/EBU
digital interface. Analog data converted from digital data is
also provided.
HDCAM format
The HDCAM format uses tape with the same 12.65 mm
width as the Betacam series to enable recording of up to
two hours of high-quality HD video. Video signal
compression uses prefilter and coefficient recording
technology.
Advanced recording and playback
functions
High-quality digital recording
This unit uses a component system to record video signals.
An AES/EBU format with a wide dynamic range is used
for 12-channel audio recording. A unique and powerful
error correction circuit and concealment circuit are used in
digital signal processing.
Accurate and stable video signal output is made possible
by setting and adjusting the internal digital video
processor.
Record/playback modes
HDCAM-SR format (SRW-5000/5500) or HDCAM
format (SRW-5500)
As the record/playback mode, you can select from the
following ten modes.
1080×1920: 59.94i/60i/50i/23.98PsF/24PsF/25PsF/
29.97PsF/30PsF
720×1280: 59.94P/50P (HDCAM-SR format only)
Playback compatibility
You can select the following compatibility playback
functions.
• HDCAM (SRW-5000)
1080×1920: 59.94i/60i/50i/23.98PsF/24PsF/25PsF/
29.97PsF/30PsF
• Digital Betacam
525/59.94i, 625/50i
However, Digital Betacam playback requires the
HKSR-5002 (option).
Internal format conversion function
By installing an optional HKSR-5001, when the operation
mode of this unit is 23.98PsF or 24PsF, a 59.94i or 60i
mode HD SDI output (audio/VITC multiplex) is made
available. Additionally, conversion in either direction
between 1080×1920 and 720×1280, and conversion from
4:2:2 signal to 4:4:4 signal is possible, and with the
additional installation of an HKSR-5003, conversion from
a 4:4:4 signal to a 4:2:2 signal.
Noiseless playback with DT heads
When using the HDCAM-SR or HDCAM format, the
dedicated playback DT heads allow you to perform
noiseless playback in the range from –1 to +2 times normal
speed, including still-picture playback. When using the
Digital Betacam format, the playback range is from –1 to
+3. However, Digital Betacam playback requires the
HKSR-5002 (option).
Video and audio confidence heads
Video and audio (channels 1 through 12, or 4 channels for
the HDCAM format (SRW-5500 only)) signals can be
recorded and simultaneously played back to check the
recording.
Internal time code generator and reader
The internal time code generator allows you to record time
code (LTC or user bits) together with video and audio
signals. Time codes (LTC or user bits) can be read during
playback using the time code reader.
Computer servo system
Computer-controlled servo motors provide direct drive for
the drum, capstan, and two reels, enabling quick and
accurate tape access.
Capstan override function
You can adjust the playback speed by ±15% to ensure
synchronization between, for example, two VTRs playing
back the same program.
Independent audio level control
It is possible to adjust the recording and playback levels
either independently on each channel or simultaneously on
all 12 channels (or 4 channels for HDCAM format (SRW-
5500 only)) while monitoring the peak values.
Tele-File
1)
memory label system
This unit incorporates the Tele-File memory label system
to allow users to read, write and update videocassette
management information, log data (IN/OUT points) and
cue point data on memory labels, providing greater
efficiency in cassette management and editing.
1) Tele-File
A contact-free system for writing, reading, and modifying video cassette-
related information on IC memory-bearing labels. Tele-File is a trademark
of Sony Corporation.
Program Play (P-PLAY) Function/Pitch
Correction Function
Program play is a function that allows play at ±5% of
normal speed. Pitch correction of the audio is possible at
the same time.
This function is available only for the combination of
SRW-5000/5500 Serial No. 12001 or higher and HKSR-
5001 Serial No. 11001 or higher.
