CHAPTER 3: Outputs

HLS Output Screen
Using the touch screen, you can generate a single-rate HLS stream or a multi-rate stream with
up to three streaming rates. In a multi-rate stream, a master playlist links the client to separate
playlists for the single-rate streams. The client can then request the
.ts
content from the
different single-rate playlists as needed.
Note:
For media delivery to iOS devices such as the iPhone and iPad, HLS
output must be encoded with H.264/AAC codecs.
Stream Name
For
Stream Name
, set a name for the output stream. Helix Broadcaster generates the single-rate
playlist using this stream name. In a multi-rate stream, each stream name typically includes a
designation for the streaming rate. For example, the stream name
500K
results in the playlist
500K.m3u8
.
Master Name (Multi-rate Streams)
To generate a multi-rate stream, create up to three outputs with similar H.264/AAC encoding
profiles. Each output should use a different video streaming rate, such as 500 Kbps, 750 Kbps,
and 1000 Kbps. The streams can use the same or different audio rates. In the
Master Name
field
for each output, set the same name, such as
master
. This name automatically becomes the
master playlist, as in
master.m3u8
.
Request URLs
The setup screen lists the request URLs, which are based on the stream names.
Single-rate Stream
If you are encoding a single-rate stream, link the HLS client to the single-rate playlist URL
listed on the screen. For example:
http://10.124.4.113:80/hls/m3u8/500k.m3u8
Multi-rate Streams
For a multi-rate stream, the client can request the master playlist. The HLS client then requests
individual streams based on information contained in the master playlist. For example:
http://10.124.4.113:80/hls/master.m3u8
