Abstract

The production of an interleaved multimedia stream for servers and client computers coupled to each other by a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the internet. Interleaved multimedia streams can include compressed video frames for display in a video window, accompanying compressed audio frames and annotation frames. In one embodiment, a producer captures separate video/audio frames and generates an interleaved multimedia file. In another embodiment, the interleaved file include annotation frames which provide either pointer(s) to the event(s) of interest or include displayable data embedded within the annotation stream. The interleaved file is then stored in the web server for subsequent retrieval by client computer(s) in a coordinated manner, so that the client computer(s) is able to synchronously display the video frames and displayable event(s) in a video window and event window(s), respectively. In some embodiments, the interleaved file includes packets with variable length fields, each of which are at least one numerical unit in length.
