Relaying Streamed Media
QuickTime Streaming Server or Darwin Streaming Server can be configured as a relay. A relay
listens to an incoming stream and then forwards that stream to one or more destinations. A
relay can reduce Internet bandwidth consumption. Relays can be useful in special broadcast
situations, especially if numerous viewers in different locations want to tune in.
Large organizations can often make good use of relays. For example, if a company regularly
broadcasts a quarterly presentation from the CEO, that broadcast can be relayed from
headquarters to branch offices.
The CEO’s presentation is captured live with a video camera. The audio and video from the
camera are encoded using QuickTime Broadcaster on a Mac OS X computer. A Mac OS X
Server computer with QuickTime Streaming Server software acts as the relay computer and
relays the broadcast of the CEO’s presentation over the Internet to destination computers
serving the company’s branch offices. Employees of the company using client computers
tune in to the destination computers to hear and watch the CEO’s presentation.
For more detailed information about setting up streamed media, see the appropriate topics
in this manual.
