Video/Audio Rates
Use the Video/Audio Configuration pages to define the video and audio sources. You can
also use the pre-configured templates to control a single video or a single audio rate.
Templates are part of the rate configuration for each audio or video source. The
Load
Template
button launches a pop-up window showing the available templates with
preconfigured values. See Encoder Configuration for more information.
Programs
Each program corresponds to one
Video
and
Audio Input
. For example if you have two video
and audio inputs (i.e. two "channels"), you can configure two programs. Each stream you
subsequently configure must be associated with a program. See Programs for more
information.
Streams
There are 16
Streams
available for configuration. A "stream" is a bundled group of resources
that describes the characteristics of the video and audio. A stream specifies the
Program
,
Video Rate
,
Audio Rate
, and
Transport Type
and can be transmitted, served, encrypted, or
archived. Once a stream is defined, it can be used by any combination of transmitters,
servers, and archivers. With most "transport types" there is no automatic rate selection: each
transmitter and server must be configured with a specific stream and rate. With "smooth
streaming," multiple video rates are delivered in one stream and IIS determines which rate to
serve. See Streams more for information.
Transmitters
There are 25
Transmitters
available for configuration. Each references a
Stream
that can be
pushed and each is selectable as unicast or multicast (RTP and transport streams only). The
configuration parameters are divided into a common section (on the Encoder Configuration
> Global page) and another section (on the Encoder Configuration > Transmitters page)
which configures each individual destination. See Transmitters more for information.
