1. A method of synchronously rendering a plurality of media streams, each media stream comprising a sequence of media samples having media-specified timing, the method comprising the following steps:

  • generating a common clock reference;

    calculating presentation times for the media samples based in part on the media-specified timing of the media samples and also based in part upon a desired synchronization of the media streams relative to each other;

    associating the presentation times with the media samples of the plurality of media streams, each presentation time indicating when the associated media sample should be rendered relative to the common clock reference;

    rendering the respective media samples of the plurality of media streams at approximate times relative to the common clock reference as indicated by the presentation times associated with the respective media samples.
