Step 3: Set Up Your Streaming Server

An administrator computer must be set up before you can configure and manage your streaming server if, as in this example, the streaming server is running headless. For information on setting up an administrator computer, see “Setting Up an Administrator Computer” in Getting Started With Mac OS X Server (included on the Mac OS X Server CD).

Any computer with a reasonably up-to-date browser connected either directly to the local network or to the Internet can be used to manage QTSS remotely once Mac OS X Server has been configured. For this example, we assume that the broadcaster laptop in the streaming setup illustration is also used for this purpose.

Although the Xserve comes with Mac OS X Server and QTSS preinstalled, the software must be configured for the particular network to which it is being added and for the specific uses to which it is to be put. For information on setting up Mac OS X Server, see Getting Started With Mac OS X Server and Mac OS X Server Administrator’s Guide, included on the

Mac OS X Server CD.

Among the questions to be answered when setting up your streaming server are the following:

Can the server computer be dedicated solely to streaming?

It’s best if your streaming server doesn’t also have to handle web serving, mail serving, and other server tasks. This example setup includes a dedicated streaming server.

How much random access memory (RAM) is needed?

The minimum required to run QTSS is 128 megabytes (MB). Estimate about 256 MB of RAM for every 50 MB of throughput you plan to serve. This setup assumes 256 MB of RAM.

How much hard disk storage is needed?

Video files can be large. A hinted one-hour presentation encoded at 300 Kbps (not optimized for a server) will take up approximately 135 MB of hard disk space. A 60-GB hard disk can store more than 400 such presentations.

Note: Here’s a formula for calculating streaming file sizes:

dataRateInBits / 8 bits * timeInSeconds = file size

QuickTime Streaming Server Darwin Streaming Server specifications

Apple QuickTime Streaming Server, also known as Darwin Streaming Server, is a pivotal technology in the realm of multimedia streaming. Developed by Apple Inc., this open-source server software is designed specifically for the efficient delivery of video and audio content over the internet. One of the standout features of Darwin Streaming Server is its capability to stream content using the QuickTime file format, which is widely adopted for rich media applications.

A core characteristic of Darwin Streaming Server is its support for the Real-Time Streaming Protocol (RTSP). This protocol enables the server to communicate effectively with user clients, ensuring smooth playback of multimedia content. RTSP also allows for advanced streaming capabilities, such as pause, rewind, and fast forward, providing users with a versatile viewing experience.

Darwin Streaming Server is built on a highly modular architecture that enhances its scalability and flexibility. It can easily handle multiple simultaneous streams, making it suitable for both small-scale projects and large-scale broadcast environments. The server can efficiently manage bandwidth, optimizing the delivery of content even during peak usage times.

Another notable feature of Darwin Streaming Server is its robust integration with Appleā€™s QuickTime technology. This compatibility enables the seamless distribution of interactive media, which is crucial for applications in education, entertainment, and corporate training. The server can stream both live and on-demand audio and video content, catering to a diverse audience.

Additionally, Darwin Streaming Server supports various streaming formats, including MP3 and AAC for audio and H.264 for video. This flexibility allows content creators to deliver high-quality media while maintaining compatibility with various devices and platforms, from desktop computers to mobile devices.

Security is another important aspect of Darwin Streaming Server. It supports encryption protocols, ensuring that sensitive content is protected during transmission. 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. Whether used for live broadcasts or on-demand content, Darwin Streaming Server remains a significant contributor to the evolution of online media delivery.
