 Chapter 3: 

OUTPUTS

For each input you define, you can create up to three outputs using the touch 
screen. You might create different outputs to generate streams with different 
streaming bandwidths or output ratios, for example.

Output Selection

To define an output, tap 

Stream Setup

 on the 

Appliance Manager

 screen. On the 

Stream Setup

 

menu, choose the stream input, such as 

Net#1

 or 

SDI#1

. Then tap the icon for the output you 

want to define (

#1

#2

, or 

#3

).

Output Stream Selection

The following table lists the types of outputs that can you create.

Output Protocols 

Protocol

Purpose

UDP with TS envelope 

Data delivered with user datagram protocol and a transport stream 
wrapper. This can be used to send the stream to a satellite link or to other 
encoders or servers. See page 17.

RTP with TS envelope

Similar to the UDP method, this output type delivers data using a 
standards-based RTP packet format. See page 17.

HTTP with TS envelope

This is a pull method that allows a client such as a server to request the 
stream using an HTTP URL. This method can be used to work around 
restrictive firewalls. See page 18.

HLS - HTTP Live Streaming

HLS output delivers transport stream files over HTTP. It is used with iOS 
devices such as the iPad as well as compatible devices. See page 19.

Smooth Streaming push

Not currently supported.

RTMP push with FLV 
envelope

This method uses Flash packaging along with the RTMP protocol. You 
can use this method to deliver the stream to a Flash Media Server. See 
page 21.
