Encoder Configuration

VBrick 9000 Encoder Admin Guide

A Stream specifies:
•

program

•

transport type

•

video rate

•

audio rate

A Stream can be 
•

transmitted

•

served

•

encrypted (in some cases)

•

archived 

Once a stream is defined, it can be used by any combination of transmitters, servers, and 
archivers. The maximum number of different stream types you can enable is shown in the 
table below. (Note that "adaptive" streaming is only supported with transport type set to 
Smooth Streaming Transport Type.) 

Field

Description

Choose Stream

Select a stream from those defined on the Encoder 
Configuration > Programs page. 

Used By

Read-only. Shows which Transmitters, Servers, and Archivers 
(future) are configured to use this stream. 

Enable Stream

Enable the selected stream. 

Stream Name

Enter a user-friendly name for the selected stream.
