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.
