HTTP and RTSP streaming
HTTP streaming is the standard way of viewing QuickTime movies stored on an HTTP server. The GoLive
streaming track is for RTSP streaming movies only. GoLive also lets you export movies as RTSP streaming movies
for use with the RTSP streaming servers.
HTTP streaming (Hypertext Transfer Protocol) Makes it possible to put movie files on a web (HTTP) server as you
do web pages and image files. Movies are downloaded in their entirety to the computer’s hard disk where the
QuickTime plug-in plays them. Because the movies are downloaded to the hard disk, viewers can replay the movies
at any time, and a higher data rate (higher quality) is ensured. If you have sprite tracks or 3D tracks, these are visible
to the viewers (whereas these tracks are not visible with RTSP streaming).
RTSP streaming (Runtime Streaming Protocol)
Requires a dedicated RTSP streaming server that sends out movie
data on an as-needed basis. No file is stored on the viewer’s computer. If the Internet is congested, thus preventing
portions of the movie from arriving on time, RTSP ignores the fact that some data might be missing. However,
because RTSP streaming works without files, it’s possible to do live broadcasts, where all viewers see the same movie
data at the same time. The advantage of RTSP streaming is that viewers don’t have to store large movie files on their
hard disks, as they do with HTTP streaming.

To add an RTSP streaming track
The client movie, which is the movie you’re creating for RTSP streaming, resides on an HTTP server and references
a streaming movie on an RTSP server. The URL to the streaming movie is stored in the client movie's streaming track.
1 Drag a Streaming Track icon from the QuickTime set of the objects toolbox into the track list area of the
Timeline Editor.
2
On the Basic tab of the Streaming Track Inspector, set the properties such as the position and size of the streaming
track. (See “To set the basic track and sample properties” on page 534.)
3
In the RTSP tab of the Streaming Track Inspector, enter the URL for the streaming movie in the Link box.
4 Click the Get Streaming Properties button to open a connection to the RTSP URL, and then obtain important
attributes about the streaming movie, such as dimensions and duration. (If the streaming content is a live broadcast,
it has no specific duration.) You can cancel your connection in GoLive to the RTSP server by pressing any key.
Use the Get Streaming Properties button to test the link to the streaming server.
5
Choose a duration from the Timeout menu to specify when you want GoLive to stop attempting to connect to the
streaming server. This setting applies only when you’re working in GoLive, and does not apply to viewing the
streaming movie in a web page.
