There are two options for building tile matrix video walls in Cisco StadiumVision:
TV-Based Tile Matrix Video Wall
A TV-based tile matrix video wall requires the use of TVs that have built in tile matrix
capabilities. The tile matrix capability is configured via RS-232 commands, which
specify the overall x and y dimensions of the matrix as well as each TV’s position in
the video wall.
capabilities. The tile matrix capability is configured via RS-232 commands, which
specify the overall x and y dimensions of the matrix as well as each TV’s position in
the video wall.
Each TV in the video wall is served by a separate DMP, and this dedicated DMP
provides the video signal as well as the RS-232 control for the TV it is connected to.
This approach allows each TV to display unique content when not operating in tile
matrix mode.

This approach allows each TV to display unique content when not operating in tile
matrix mode.
When operating in tile matrix mode the TVs are fed the same video signal. Based
on the TV’s tile matrix configuration, the TV knows to first scale input video to the
size of the configured x,y dimensions, then to display its “piece” of the overall
display based on its configured position within the matrix.

Depending on whether the TVs in question support daisy-chaining of the video
signal, the common video feed for all TVs is achieved in one of two ways. In the
case where the TVs do not support daisy-chaining of the video signals, an extra
DMP is deployed to act as the “video wall DMP.” The video signal from this DMP is
routed through a splitter and to a secondary video input port on each TV in the video
wall.
