A survey of playlist formats

Published on 2003-11-17, by Lucas Gonze, ©Lucas Gonze.

This document is a survey of playlist data formats. It is useful in two ways. One, as a collation of data which is normally scattered all over the web, it is a helpful reference. Two, having this data in one place makes it easier to observe patterns.

Playlists are comparatively simple objects. They are nothing but lists # here is the first song, here is the second. As a result they fail to excite the imagination of many people, because the expressive possibilities seem too limited. But from my background as a musician, arranger and composer, I know that the sequencing of aesthetic experiences has huge expressive possibilities. In my work on playlists I aim to help extend the expressive power of sequencing to objects on the world wide web.

ID3 tag version 2

Published on 1998-03-26, by M. Nilsson, .

The recent gain of popularity for MPEG layer III audio files on the internet forced a standardised way of storing information about an audio file within itself to determinate its origin and contents.

Today the most accepted way to do this is with the so called ID3 tag, which is simple but very limited and in some cases very unsuitable. The ID3 tag has very limited space in every field, very limited numbers of fields, not expandable or upgradeable and is placed at the end of a the file, which is unsuitable for streaming audio. This draft is an attempt to answer these issues with a new version of the ID3 tag.

M3U (WinAmp) Play List Specification

Published on 2003-08-12, by Glenn J. Schworak, .

Winamp™ playlists are just a text file containing links to the location of the proper file. You can crate or edit a playlist in any text editor. It could be anything to MP3, WMA, or even another playlist. Just because something is in a playlist, doesn't mean Winamp can play it though. Winamp will just skip over unknown file formats. This document will hopefully toy to clarify the differences of the playlist formats available.

RealSystem: SMIL 2.0

This first example shows how a simple SMIL playlist with video elements can be done. The first 60 seconds of each video are played sequentally in the region "r1". Additionally the first 30/60 seconds of video two and three are skipped.

SMIL Basics

When your streaming presentation contains multiple clips—such as a video and streaming text played together—you use Synchronized Multimedia Integration Language (SMIL) to coordinate the parts. Pronounced "smile," SMIL is a simple but powerful markup language for specifying how and when clips play. This chapter introduces you to SMIL, its advantages, and its syntax rules.
