Overview
Features
The CBK-RPU7 Remote Production Unit is a video
transmission device that incorporates a Sony-
developed codec chip. It employs QoS technology
and an HEVC codec to achieve high-compression,
high-quality video data up to 4K 60p and network
transmission with low latency. In addition to wired
LAN connection, connecting the unit to a
compatible 5G communications device via USB
enables wireless video transmission at high-
quality for mobile live broadcast production.
Supported Transmission Signals
Video signals
• 3840×2160/23.98p, 3840×2160/50p,
3840×2160/59.94p
• 1920×1080/50p, 1920×1080/59.94p
• 1920×1080/50i, 1920×1080/59.94i
• 1280×720/50p, 1280×720/59.94p
Audio signals
• Linear PCM, 24-bit, 48 kHz (up to 4 channels)
Ancillary signals
You can specify ancillary signals to transmit using
a filter function based on the DID (Data Identifier).
Up to eight types of DID are supported.
The transmission of all types of ancillary signals is
not guaranteed.
Supported Networks
The unit supports two types of network
connectors.
Networks that are connected to the connectors
are assumed to be either a dedicated line or a
bandwidth-guaranteed shared network with
guaranteed low latency, stable transmission
bandwidth, and quality.
LAN connector
Video transmission is supported using the built-in
LAN function of the unit.
USB connectors
Video transmission is supported using the
tethering function of a 5G communications
device.
Notes
• Simultaneous video transmission using the LAN
connector and USB connectors is not supported.
• Low latency performance requires a high-
quality network environment, so low latency
performance may not be fully exhibited
depending on the environment.
• This unit is not intended to be operated
constantly powered-on for extended periods of
time.
Logging In/Logging Out
A user account is required to log in to the unit.
Roles must be configured for user accounts, and
privileges differ depending on the role.
Role
Description
Maintainer
Role for performing maintenance.
Initial setup and changes to the
installation environment can be
performed, but tasks relating to
normal operation of the unit cannot be
performed.
Operator
Role for operating the unit. Use a user
with this role for normal operation.
Guest
Role for monitoring the operation
status of the unit. Changes to settings
and operation of the unit cannot be
performed.
Due to the policy of granting minimal privileges
on the unit for security reasons, there is no role
(such as a superuser) that can perform all tasks.
Create and use user accounts with roles that are
appropriate for configuration and operation.
The unit has an internal authentication server that
manages the access of user accounts using
authentication and authorization policies based
on OAuth 2.0 and Open ID Connect.
