16 Chapter 2 QuickTime on the Internet
To save an Internet movie on your hard disk:
1 When the movie finishes loading, click the down arrow in the playback controls.
2 Choose Save > Save As QuickTime Movie.
If this command is not available, the movie is authored so that it cannot be saved.
Working With Streamed Files
You can use QuickTime Player to view movies streamed from the Internet.
To view Internet streams:
1 In QuickTime Player, choose File > Open URL.
2 Enter the URL of the stream you want to listen to.
Viewing Streamed Files Behind a Firewall
QuickTime streaming chooses the best protocol (a method of communicating via the
Internet) for your needs. Typically, QuickTime streaming uses a protocol called RTSP to
ensure the best performance. (RTSP stands for Real-Time Streaming Protocol.) If your
network connection is protected by a firewall, you may want to use the HTTP protocol
instead.
To use HTTP streaming:
1 Open System Preferences, click QuickTime, click Connection, and click Transport Setup.
2 Select “Use this protocol and port ID,” and choose HTTP from the Transport Protocol
pop-up menu.
If QuickTime can configure itself for your firewall, you can now watch streaming
QuickTime movies. If you still experience problems, contact your network administrator
or see the information on the Apple QuickTime website.
About Instant-On Streaming
QuickTime 6 (and later) includes Instant-On, an advance in Apple’s patent-pending Skip
Protection technology that dramatically reduces buffer, or wait, time when you view a
streaming video. Instant-On provides an instantaneous viewing experience; you can
click around or scrub video as if it were on your hard disk.
You must have a broadband connection to experience Instant-On. The responsiveness
of Instant-On is affected by available bandwidth and the size, or data rate, of the
content. It can also be affected by the codec used to compress the streaming video.
