Abstract: A new approach is proposed that contemplates systems and methods to support multi-device rendering of multimedia presentations by allowing users of various presentation preparation and display programs to make their work product available for viewing on various hardware and software platforms on which the presentations would not otherwise be rendered correctly. First, multimedia presentations created by a user/author in their original format are generated and uploaded to a centralized repository. The uploaded presentations are then converted to a set of intermediate files in a format different from the original format of the presentations, wherein the intermediate files can be downloaded to and rendered on the hardware and software platform of a specific device associated with a viewer while maintaining the visual and audio integrity of the original presentation.

Abstract: A system for composing an audio-visual presentation over a communications network includes a composer system having a computer processor and associated memory and a telephone device, the composer system having a presentation containing at least one visual slide stored in the memory, and a host system including a computer processor and associated memory. The composer system: A. establishes a connection between the computer processor and the host system over a communications network and uploads the presentation to the host system over the communications network; and B. establishes a connection between the telephone device and the host system and records an audio narration clip for each of the at least one visual slide. The host system synchronizes each audio narration clip with its associated visual slide and stores the resulting audio-visual presentation in the memory of the host system.
