Abstract

A compressed data file for real time display of multimedia applications, e.g., animation (51), on a network (11) is disclosed. The file includes general information about the animation. Also included in the file are complete segment blocks of information (65, 67) representing single frames in the animation. Each frame is made up of multiple images (layers) which are overlapped. Each image is made up of vector objects (135). Display of the file is conducted through asynchronous transfer (149) of data so that as a frame is displayed, the next frame is transmitted and received by an end user for immediate display.

Claims

AMENDED CLAIMS[received by the International Bureau on 29 December 1997 (29.12.97); original claims 1-3 replaced by new claims 1-7 (2 pages)]
1. A method for conveying a multimedia program from a source computer to a destination computer, comprising: providing at the source computer a series of data segments, including a predetermined number of such data segments, each data segment corresponding to a frame displayed in the multimedia program; producing a general information block including information indicative of the predetermined number of data segments in the series; transmitting the general information block to the destination computer; and transmitting the series of data segments to the destination computer, such that the destination computer executes the program and terminates the program responsive to the information in the general information block after the predetermined number of segments has been reached.
2. A method according to claim 1, wherein transmitting the series comprises transmitting the series of data segments substantially without setting a segment delimiter.
3. A method according to claim 1, wherein transmitting the series comprises transmitting each of the data segments in the series while the frame corresponding to a previous one of the data segments is displayed at the destination computer.
4. A method according to claim 1, wherein producing the general information block comprises producing a block including one or more indicators respectively identifying one or more of the data segments in the series, and wherein transmitting the series comprises transmitting a sub-series of the data segments to the destination computer, beginning with the data segment identified by one of the one or more indicators, responsive to selection of the indicator at the destination computer.
5. A method for conveying a multimedia program from a source computer to a destination computer, comprising: providing at the source computer a series of data segments, including a predetermined number of such data segments, each data segment corresponding to a frame displayed in the multimedia program; producing a general information block including one or more indicators respectively identifying one or more of the data segments in the series; transmitting the general information block to the destination computer; and responsive to selection of one of the one or more indicators, transmitting a sub-series of the data segments to the destination computer, beginning with the data segment identified by the selected indicator.
6. A method according to claim 5, and comprising associating at least one of the one or more indicators in the general information block with a corresponding hot area in one or more of the frames.
7. A method according to claim 6, wherein a user of the destination computer selects the at least one indicator by selecting the hot area in the one or more of the frames.
