5.12. Crosspoint Switching Examples

The VINX devices can be arranged and used as a matrix. The working method
of such a system is different than a dedicated matrix switcher. Therefore, the
approach and the control commands are also different.
Important Notices about System Usage
▪ The switching is realized in practice by setting the Video stream ID of the
given Decoder to the same ID as the desired Encoder.
The commands are addressed to each Decoder separately via LAN.
▪
▪ The crosspoint state cannot be queried by a global command.
▪ TX means the Encoder, RX means the Decoder in the drawings.
The following example demonstrates a 4x4 matrix layout and crosspoint-related commands how they can
be used for crosspoint-handling. The initial state in the example is diagonal: I1-O1; I2-O2; I3-O3; I4-O4.
5.12.1. Switching an Input to an Iutput
ç SET /SYS/MB/PHY.VideoChannelId=2
æ pw /SYS/MB/PHY.VideoChannelId=2
Above command is sent to the RX1 Decoder.
5.12.2. Switching an Input to All Iutputs
ç SET /SYS/MB/PHY.VideoChannelId=2
æ pw /SYS/MB/PHY.VideoChannelId=2
Above command is sent to all Decoders separately.

5.12.3. Switching the Source of a Video Wall

The source Encoder of an existing video wall (VW1) can be changed. In this case,
the Video stream ID of the affected Decoders must be changed one-by-one.
ç SET /SYS/MB/PHY.VideoChannelId=4
æ pw /SYS/MB/PHY.VideoChannelId=4
Above command is sent to all Decoders in the Video wall.
INFO:
The video wall properties are not changed by switching the Encoder. Each Decoder will show
the same area of the (new) image as it had been set previously.

The commands have to be sent to the Decoders one-by-one thus, the switching
is realized in practice by setting the Video stream ID of the Decoders to the same
ID as the desired Encoders.
ç SET /SYS/MB/PHY.VideoChannelId=4
æ pw /SYS/MB/PHY.VideoChannelId=4
Above command is sent to RX1.
ç SET /SYS/MB/PHY.VideoChannelId=3
æ pw /SYS/MB/PHY.VideoChannelId=3
Above command is sent to RX2.
ç SET /SYS/MB/PHY.VideoChannelId=2
æ pw /SYS/MB/PHY.VideoChannelId=2
Above command is sent to RX3.
ç SET /SYS/MB/PHY.VideoChannelId=1
æ pw /SYS/MB/PHY.VideoChannelId=1
Above command is sent to RX4.
