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:

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).

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.

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.

If using RTP, both the Target Port and Target Audio Port must be different.
