Media
This section provides information you need to broadcast live or prerecorded media as
streaming video and/or audio. You can also learn about instant-on streaming, creating
playlists, setting up a web page with streamed media, and bandwidth considerations.
About Instant-On Streaming
Viewers watching a streaming video with QuickTime 6 and later will benefit from Instant-On,
an advance in Apple skip-protection technology (patent pending) that dramatically reduces
buffer, or wait, time for an instantaneous viewing experience. Viewers can click around or
scrub video as if it were on their hard disks.
Users must have a broadband connection to experience instant-on streaming. The
responsiveness of instant-on streaming is affected by available bandwidth and size, or data
rate, of the content. Responsiveness can also be affected by the codec used. Hinted movies
made using the QDesign Audio codec, for example, may not be instant-on capable.
Preparing Prerecorded Media
Prerecorded media can be played back as a simulated live stream in a playlist when prepared
properly.
To prepare prerecorded media for broadcast in a playlist:
1 Use the same number and types of tracks for each movie in the playlist.
Be sure all the media files contain compatible media types. For example, all audio tracks
should use the same encoding, sampling rate, compression, and bit rate. All video tracks
should also use the same encoding, compression, and bit rate.
2 Format the media in each file in the same way.
For example, use the same frame size for each video track.
3 For movie playlists, be sure each media file is a hinted QuickTime movie or a hinted
MPEG-4 file.
For an MP3 playlist, each file must be an MP3 audio file with the same sample rate (the data
rates do not need to be the same). Do not hint MP3 files when preparing an MP3 playlist.
4 Copy all media files to your streaming server.
