Abstract
Abstract A multimedia system and method for providing consistent playback performance across a variety of playback system and network configurations. The multimedia system and method includes an authoring tool element, an interleaver element, and a playback interpreter element. The authoring tool is used by an author build a presentation script specifying images and/or sounds and times for their playback. The authoring tool determines whether the images and/or sounds can be delivered for playback at the specified times within the bandwidth specified by the author. An interleaver element is used to compress and combine images and sounds data from existing multimedia data elements into an interleaved playback data stream for delivery of a multimedia presentation within the author-specified bandwidth. The playback interpreter element is used to deinterleave, decompress and interpret the playback data stream in a timed, coordinated manner to provide consistent predictable playback performance. The playback interpreter element includes event handling software for monitoring events and initiating branching or other conditioned performances based on conditional statements extracted from the playback data stream during run-time.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
160 words
A computer implemented method for generating a multimedia presentation data stream of at least one of images and sounds for timed, coordinated reproduction of said at least one of images and sounds, comprising the steps of: generating a list specifying a plurality of data elements representing at least one of images and sounds and, for at least some of said data elements, specifying one or more times for playback of said images and sounds; selecting a playback bandwidth with which to deliver at least one of said images or sounds; identifying from said list said data elements and said one or more times for playback of said images and sounds; dividing each of said data elements into one or more data portions; and combining said data portions in a multimedia presentation data stream for delivery of said data portions to a computer system within said selected bandwidth for timed coordinated reproduction of said at least one of images and sounds.
Claim 2
Dependent Claim
160 words
A computer implemented method for generating a multimedia presentation data stream of at least one of images and sounds for timed, coordinated reproduction of said at least one of images and sounds, comprising the steps of: generating a list specifying a plurality of data elements representing at least one of images and sounds and, for at least some of said data elements, specifying one or more times for playback of said images and sounds; selecting a playback bandwidth with which to deliver at least one of said images or sounds; identifying from said list said data elements and said one or more times for playback of said images and sounds; dividing each of said data elements into one or more data portions; and combining said data portions in a multimedia presentation data stream for delivery of said data portions to a computer system within said selected bandwidth for timed coordinated reproduction of said at least one of images and sounds.
Claim 3
Dependent Claim
56 words
The method according to claim 1 further comprising the steps of: determining, for each of said time-specified images or sounds, if a data quantity for reproducing said images or sounds can be delivered at said specified time within said specified bandwidth; notifying an operator if said images or sounds cannot be delivered at said specified time.
Claim 4
Dependent Claim
33 words
The method according to claim 2 further comprising the steps of: determining a delayed time at which said time-specified images and sounds can be reproduced; and notifying an operator of said delayed time.
Claim 5
Dependent Claim
28 words
The method according to claim 1 including the further step of accessing said multimedia presentation data stream to reproduce said images and said sounds at said specified times.
Claim 6
Dependent Claim
137 words
A computer implemented method for regenerating a replayable multimedia presentation data stream generated from a list of data elements representing images and sounds, comprising the steps of: identifying original level indicators for each of said data elements in said data stream, said original level indicators being determined at the time said multimedia presentation data stream was generated; generating a current list of data elements; generating a current level indicator for each of said data elements in said current list; comparing said current level indicators with said original level indicators to identify one or more updated data elements; locating original data portions in said multimedia presentation data stream which correspond to said updated data elements; dividing said updated data elements into one or more updated data portions; and replacing said original data portions with said updated data portions.
Claim 7
Dependent Claim
137 words
A computer implemented method for regenerating a replayable multimedia presentation data stream generated from a list of data elements representing images and sounds, comprising the steps of: identifying original level indicators for each of said data elements in said data stream, said original level indicators being determined at the time said multimedia presentation data stream was generated; generating a current list of data elements; generating a current level indicator for each of said data elements in said current list; comparing said current level indicators with said original level indicators to identify one or more updated data elements; locating original data portions in said multimedia presentation data stream which correspond to said updated data elements; dividing said updated data elements into one or more updated data portions; and replacing said original data portions with said updated data portions.
Claim 8
Dependent Claim
99 words
A computer implemented method for generating a reconfigurably processed data stream of at least one of images and sounds, comprising the steps of: receiving a plurality of data portions which represent at least one of images and sound, with at least some of said images and sounds having a specified playback time; receiving a conditional input statement appended to one or more of said data portions for varying the processing of one or more of said data portions according to operator input received at run-time; and combining said data portions and said conditional input statements into a data stream.
Claim 9
