If you want to use SMIL timing and linking with the clips, though, it is easier to define the sequence within a SMIL file. So instead of writing a separate SMIL file for each clip, you write only one SMIL file that defines all of the features of the sequence.

A sequence is the simplest type of SMIL group to create. In the order that you want to play Just list the clips within <seq> and </seq> tags. Following example shows the entire SMIL markup required to play three audio clips in sequence:

In the preceding example, the second clip begins when the first clip finish and the third clip begins when the second clip finish. A sequence can include any number of clips, and the clips can be of any type. You could add a video clip to the sequence also.

RealOne Player treats the sequence as a single presentation when you enclose clips in <seq> and </seq> tags. If each clip in the preceding example is two minutes in length. e.g. the RealOne Player status bar indicates that the presentation is six minutes long. Because RealOne Player treats the sequence as a single presentation, viewers can use the timeline slider to seek through all the clips, but cannot choose individual clips through the RealOne Player Play>Next Clip command.

It is not necessary to always use <seq> and </seq> tags to create a clip sequence. Whenever clips are not listed in a groups, RealOne Player play them in sequence. For instance, the following markup, which has no <seq> and </seq> tags, play three audio clips in sequence just like the preceding example:

RealOne Player treats each clip as a separate presentation when you do not use a <seq> group. Suppose that each clip in the preceding example lasts two minutes. When the sequence start the RealOne Player status bar indicate that the presentation lasts two minutes. When the first clip ends, RealOne Player's timeline slider resets, the second clip starts, and the status bar indicate another two-minute presentation. This action repeats when the third clip plays. At any point, the viewer can select a different clip with the RealOne Player Play>Next Clip command.
