Blackmagic SmartView Ethernet Protocol v1.3
Summary
The Blackmagic SmartView Ethernet Protocol is a text-based status and control protocol, very similar in
structure to the Videohub protocol, that is accessed by connecting to TCP port 9992 on a SmartView or
SmartScope device.
Upon connection, the SmartView or SmartScope device sends a complete dump of the state of the device.
After the initial dump, state changes are sent asynchronously.
The device sends information in blocks which have an identifying header, followed by a colon. A block can
span multiple lines and is terminated by a blank line.
To be resilient to future protocol changes, clients should ignore blocks they do not recognize, up to the
trailing blank line. Within recognized blocks, clients should ignore lines they do not recognize.
Protocol Preamble
The first block sent by the SmartView Server is always the protocol preamble:
PROTOCOL PREAMBLE:↵
Version: 1.3 ↵
↵
The version field indicates the protocol version. When the protocol is changed in a compatible way, the
minor version number will be updated. If incompatible changes are made, the major version number will
be updated.
Device Information
The next block contains general information about the connected SmartView or SmartScope device.
SMARTVIEW DEVICE:↵
Model: SmartView Duo↵
Hostname: stagefront.studio.example.com↵
Name: StageFront↵
Monitors: 2↵
Inverted: false↵
↵
This example shows the output for a SmartView Duo device, which has two LCDs. The INVERTED flag
indicates whether the device has detected that it has been mounted in an inverted configuration to optimize
LCD viewing angle.

↵ carriage return
… and so on
Version 1.3 of the Blackmagic SmartView Ethernet Protocol
was released with SmartView 1.3 software.
