A reference movie can simply be a text file with a “.mov” filename extension (such as “ref.mov”). The format for the contents of the file is as follows:

rtsptext rtsp://my.streamingserver.com/sample.mov

Creating Links to MP3 Playlists

If you want to put an MP3 playlist on the web, you need to create an audio metafile that directs the web browser to your playlist and opens the user’s MP3 player. There are two types of audio metafile you can use: M3U and PLS. To create the audio metafile, use a text editor to create the file, include the proper extension (“.m3u” for M3U metafiles and “.pls” for PLS metafiles) at the end of the filename, and format it as described here.

The M3U file contains a single line of text in this format:

http://your.ip.addr:8000/mountpoint

A PLS file uses this format:

[playlistname]

File1=http://your.ip.addr:8000/mountpoint

Title1=Playlist Title

Length1=-1

NumberOfEntries=1

Version=2

Place the .m3u or .pls file in the same directory as your web site and link to it just as you would link any other downloadable file. Most web browsers are configured to open .m3u and

.pls files using the user’s MP3 player automatically.

Bandwidth Considerations

It’s generally not a good idea to connect a streaming server to the Internet or local area network by Digital Subscriber Line (DSL) or cable modem. The server will be severely limited by the relatively small bandwidth of DSL and cable modems for uploading data. In some cases, running a server on a DSL connection may break a DSL service agreement. Consult your DSL or cable modem service provider before setting up the server.

When authoring Real-Time Transport Protocol (RTP) streams, make sure they do not exceed 75 percent of anticipated client throughput. For example, don’t use a rate higher than 20 kilobits per second (Kbps) for a 28 Kbps modem connection. For a typical 56K modem connection, don’t use a rate higher than 31 Kbps. For a T1 (1500 Kbps) client connection, don’t use a rate higher than 1125 Kbps.

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 Apple’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.
