Overview
The HDRC-4000 HDR Production Converter Unit converts
HDR video signals using the OETF standard. OETF supports
several standards, including Sony’s original S-Log3 curve,
SMPTE ST 2084 (PQ) and ITU-R BT. 2100 (HLG), and
supports mutual conversion between standards.
The unit also features the AIR MATCHING (Artistic Intent
Render Matching) function, which allows you to convert to
any format, using HDR signal OETF mutual conversion, so
that the “look” is correct on a display that supports that
particular OETF standard format.
In addition to HDR OETF conversion, it also supports
simultaneous mutual conversion between HDR/SDR, 4K/HD,
and 2020/709 color space for conversion of various signal
formats.
This unit also supports external reference signals, and can be
operated as a video signal frame synchronizer.
Features
Various video signal format conversion
support
Supports simultaneous conversion of various signal formats.
• HDRyHDR: OETF signal standard conversion
• HDRySDR: Dynamic range conversion
•4KyHD: Resolution conversion
• BT.2020yBT.709: Color space conversion
In addition, the SDI signal input/outputs also support 2SI/
SQD, 3G-SDI Level-A/3G-SDI Level-B, and HD-SDI (HD
only) signal formats.
Simultaneous output of 4K and HD signals
Simultaneously outputs 4K and HD signals as output video
derived from a single input signal.
The 4K and HD signal conversion settings can be configured
independently.
Dual system signal processing
Equipped with a dual system (channel A, channel B) signal
processing function.
A 4K signal or HD signal can be freely selected for each input
setting.
Video input/output
Inputs
Channel A
• 4K × single system: 3G-SDI × 4ch
• HD × single system: 3G/HD-SDI
Channel B 1)
• 4K × single system: 3G-SDI × 4ch
• HD × single system: 3G/HD-SDI
1) You can also select the channel A input signal for the channel B
input.
Outputs
Channel A
• 4K × dual system: 3G-SDI × 4ch
• HD × single system: 3G/HD-SDI
• HD monitor × single system: HD-SDI
Channel B
• 4K × dual system: 3G-SDI × 4ch
• HD × single system: 3G/HD-SDI
• HD monitor × single system: HD-SDI
External reference signal
The output signal can be synchronized to an external
reference signal (HD tri-level sync or SD sync).
The unit is also equipped with a frame synchronizer function
allowing it to operate as a frame synchronizer.
If an external reference signal is not input, the output can be
synchronized to the channel A input signal. Operation without
an external reference signal, and input only on channel B is
not guaranteed.
Supported signal formats
4K: 59.94P, 50P (3840×2160)
HD: 59.94P, 50P, 59.94i, 50i (1920×1080)
Low-latency output
All signal processing is performed within a single frame, and
the output video is delayed by one frame.
When the frame synchronizer function is on, the output is
delayed by two frames (when 4K is output as SQD signals,
there is a further one frame delay for the whole signal).
Minimum delay setting
When set to minimum delay mode, signals that are output
without resolution conversion (4K/HD) can be output with a
delay of only a few lines (in HD signal terms) (for example, 4K
2SI HDR signal OETF conversion).
However, for 4K input and/or output SQD signals, the signal
output will have a delay of one frame or higher (same as
minimum delay mode not being set).
Through mode setting
In through mode, SDI signals input on the 4K input
connectors (BNC × 4) are output on the 4K output connectors
(BNC × 4) with a 1-line delay (in HD signal terms). Input/
output on the HD signal side is disabled.
16-channel embedded audio support
Audio signals (16-channel) can be embedded in the SDI
signals.
The audio signal with a delay matching the video signal is
embedded in the output signal.
Remote control
Supports the remote control by Sony system camera
products.
The menu can be operated from an RCP-1500 series
Remote Control Panel or an MSU-1000 series Master Setup
Unit.
Configuration file
The various device settings can be stored in any of up to 62
configuration files.
File readout control is also supported from an external GPIO
(D-SUB connector).
