This is particularly valuable for organizations that need to secure proprietary content or deliver private media to specific audiences.

In conclusion, Apple QuickTime Streaming Server, or Darwin Streaming Server, stands out as a powerful tool for multimedia streaming. Its integration of RTSP, compatibility with QuickTime, modular architecture, and robust security features make it an ideal choice for businesses and content creators looking to deliver high-quality streaming experiences.
