Abstract:
A method for the presentation of heterogeneous media on a network comprising:dividing the presentation of a scene into a sequence of multiple phases for transferring from a network server to a network client terminal, each succeeding phase in the sequence duplicating in greater detail one or more images in the preceding phase, with the code for each of the phases transferred before the data of that phase;transferring to the client terminal code and data for two or more of the multiple phases and code to monitor and control the renderings of the presentation;monitoring, at the client's terminal, of the progress of the performance at least one of the phases as it is rendered at the clients terminal; andusing the transferred code for monitoring and controlling the rendering of the performance, changing at the client's terminal the performance from the data of a rendered phase to the data of the more detailed rendition containing the duplicated images in the succeeding phase intermediate the transfer of the data of the second phase when sufficient data from the succeeding phase has been transferred to the client's terminal and the rate of transfer to the client's terminal is sufficient to provide from the point of change uninterrupted and seamless rendering of the images of the presentation.
