Multimedia systems usually integrate different types of data streams, including continuous media (e.g., audio and video) and discrete media (e.g., text and still images). Media data must be presented at precise time instants defined by the rate of presentation. A media data stream schedules presentation of samples within a given time base. In this way, objects in the same time base are synchronized.

Abstract
With the rapid advance in Web and multimedia technologies, authoring various types of multimedia content and distributing them on the Web has been very popular for many years. These technologies are applied in e-learning extensively, such as from language learning (e.g., ESL) to professional domain knowledge (e.g., computer science). In contrast, e-learning systems focusing on art domains, especially for kids or teenagers, are few. This is a notable shortcoming, because from a technical viewpoint, current advances in multimedia technology via the Web promise this kind of application. On the other hand, compared with technologies needed for more general-purpose knowledge, cultivating children’s art through e-learning technology needs much more edutainment ingredients – it must be interesting and interactive and offer multimedia. Realizing this kind of e-learning is really a challenge, not only from a pedagogical viewpoint (the first ingredient) but also technical ones (the latter two ingredients).
