    Can I use the same computer to simultaneously capture QuickTime video and stream it on the Internet?

    Note: QuickTime Streaming Server 1.0.2 Update is available for downloading. For more information see Article 60462: " QuickTime Streaming Server 1.0.2 Update: Read Me "

DISCUSSION

    QuickTime Streaming Server (QTSS) can stream pre-recorded QuickTime-compatible audio and video (media) originating at the server, as well as reflect live multicasts and unicasts (broadcasts) originating from another computer (or source).

    QTSS can reflect any QuickTime-compatible broadcast. Examples of this range from a Mac OS computer using Sorenson Broadcaster to a Windows NT computer using Cisco IP/TV, IBM VideoCharger, or SGI WebFORCE MediaBase.

    Reflecting a signal can be useful in separating high-bandwidth (broadband) users on the intranet from low-bandwidth users on the Internet. In this scenario, video is captured and compressed on a transmitter (computer), and broadcast to a QuickTime Streaming Server computer(s), or local viewers. Remote viewers on the Internet connect to the reflected stream through QuickTime Streaming Server.

    By separating the two tasks (broadcasting and reflecting) it is much easier to tune the performance of both computers. Reflecting a broadcast also allows for scaling, with the addition of multiple QTSS reflectors or multiple source computers.

    Capturing and compressing video and audio in real time consumes the majority of a computer's bus and CPU resources. Adding server responsibilities on top of that only increases the demand on system resources and can diminish performance.

    Stored movies can be compressed for higher quality or multiple data rates at slower than real time, before uploading to a busy server--thus allowing for remote administration.

    Note: QuickTime 4 is required to view streaming movies on a Mac OS or Windows client.
