Developer Information

Blackmagic SmartView Ethernet Protocol v1.1

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 device.

Upon connection, the SmartView device sends a complete dump of the state of the device. After the initial

dump, state changes are sent asynchronously.

The SmartView 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: 1.1 ↵

↵

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 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 LCD displays. The INVERTED

ﬂag indicates whether the device has detected that it has been mounted in an inverted conﬁguration to

optimize LCD viewing angle.

… and so on

Version 1.1 of the Blackmagic SmartView Ethernet Protocol

was released with SmartView 1.1 software.
