VG-Series Modero Touch Panels
Displaying Stream Content
Overview
The current build of Modero firmware currently supports the display of both MPEG-2 and MPEG-4
media streams via the TPDesign touch panel pages. These incoming media signals can utilize either a
UDP or RTP Transport protocol. For the purposes of these instructions, we will be setting up a Modero
touch panel to display an incoming media stream sent from a MAX Video Encoder. To fully utilize both
MPEG-2 and MPEG-4 streaming functionality, you must be using the latest Modero firmware.
MAX-CSE Media Encoder can currently stream A/V signals and direct them to IP-enabled devices
capable of interpreting and displaying the incoming MPEG data using either RTP or UDP Transport
Protocols. These outgoing signals can be displayed by a:
VG-Series Modero Touch Panel (supporting MPEG-2/MPEG-4 streams)
Computer running third-party multi-media player capable of supporting UDP/RTP streaming
protocols.
At this time, we are recommending using the open-source VLC Media Player
®
(version 0.8 or higher).
Supported transport protocols include: UDP or RTP.
A protocol is a convention or standard that controls or enables the connection, communication, and data
transfer between two computing endpoints. In this case, between the MAX-CSE and the target
IP-capable device (Modero).
UDP (User Datagram Protocol) is a connectionless protocol, such as TCP, that runs on top of
IP networks. Unlike TCP/IP, UDP/IP provides a direct way to send and receive datagrams
over an IP network. It's primarily used for broadcasting messages over a network. Data is sent
as a Transport Stream by using only the MPEG-2 codec.
In a UDP stream, only a Target (video) Port is needed since both the audio and video
information are transported together to the same port on the destination device.
RTP (Real-Time Transport Protocol) is an Internet protocol used for transmitting real-time
data such as audio and video as separate entities. Data is sent as an Elementary Stream which
can use both the MPEG-2 and MPEG-4 codecs.
In an RTP stream, both a Target (video) Port and Target Audio Port are required
because the audio and video are delivered to a destination as separate data elements.
These elements are then directed to two separate ports where they are then
"synced-up" by target device/application.
IP Multicasting is supported under both the UPD and RTP communication protocols.
If using RTP, it is strongly recommended that this port number be an even
value. Using an odd numbered port value can cause the stream from a
MAX-CSE to not be properly recognized by the target Modero panel.
If using RTP, both the Target Port and Target Audio Port must be different.
