Displaying Stream Content

VG-Series Modero Touch Panels
IP Multicasting
is a method of sending out large amounts of data. IP Multicast allows a server
to broadcast a message to many recipients simultaneously. Unlike traditional Internet
communication, that requires separate connections for each source-destination pair, IP
Multicasting allows several recipients to share data from the same source. This means that just
one set of packets is transmitted to all the destinations.
An ideal method of sharing a single stream to several destinations.
One of the best uses for this method would be if an educator (or institution) wanted to stream (via either
UDP or RTP) its lecture series to a variety of students simultaneously around the world. Every student
could connect and receive the stream without having to wait their turn to view the content or see a severe
drop in transmission quality.
Requirements for Receiving Streamed Content
To receive and display content via a Modero panel:
Verify you have installed the latest version of TPDesign4 on your PC. Updates are available
from the
www.amx.com
>
Tech Center
>
Application Files
>
Touch Panel Design Tools
section of the website. This application is needed to create the necessary page (popup page)
used to display the incoming MPEG audio/video stream, identify the IP of the source
MAX-CSE, and define the target audio/video ports on the panel.
Verify you have installed the latest firmware on your target Modero panel. Updates are
available from the
www.amx.com
>
Tech Center
>

>
Modero Panels
section of the website. Modero VG-Series firmware version 2.55.12 or earlier only supports
MPEG-2 streaming media (
using UDP
).
MPEG-4 is only supported by the VG-Series Modero panel firmware version 2.60.25 or
higher.
It is necessary to understand that Modero firmware is configured to look for audio on a port
whose value is two greater than that set for the video port. When configuring the Target Video
and Target Audio ports within the MAX-CSE’s UI Stream Profiles page, the value entered
into the
Target Audio
field must be exactly 2 above the value entered into the
Target Port
(video) field.
If you enter a
Target Port
value of
5000
, when using RTP, you must enter a value
of
5002
into the
Target Audio Port
field.
If using UDP, only the
Target Port
(video) field is user-definable because both the
video and audio are sent out by the CSE as one stream and therefore there is no
reason to define a separate audio port. Entering a value of
5000
into this field will,
by default, cause the target Modero panel to look for the incoming audio portion of
the stream on the same port as the video (port
5000
).
Obtain the IP Address being used by the target Modero panel by locating the
IP Address
field
on the firmware’s System Settings page.
If using RTP (as both the Target Port and the Target Audio Port for the split stream),
it
is strongly recommended that this port number be an even value. Using an odd
numbered port value will cause the stream to not be properly recognized by the
target Modero panel.
When using Modero firmware version 2.60.25 (or higher), a UDP Transport Protocol
can use either odd or even ports.
