Embodiment Construction

[0030] figure 1 Shown is a receiver R, such as a mobile phone, which communicates with at least two external data sources (servers A and B) and receives from these external data sources descriptions of scenes and graphical objects to be displayed by said receiver R binary data stream.

[0031] Graphical animations are loaded as follows:

[0032] Receiver R requests graphic animation content from a source constituted by server A.

[0033] This server A sends to said receiver R a content S (graphic scene) describing a spatio-temporal arrangement of graphical objects.

[0034] This is illustrated by arrows 1 and 2, which represent the request for content sent by receiver R to source A, and the sending of that content by said source A to receiver R. FIG.

[0035] When the described graphical scene comprises a synthetic graphical object OC, the receiver R queries the designated server B about the information that said receiver R has just received from server A, as a particular s...

Abstract

A method for the management of descriptions of graphic animations for display, characterized in that a graphic animation is defined by a set of data describing a spatio-temporal arrangement of graphic objects to be displayed and in that said set comprises, for at least one of said graphic objects, data describing primitives corresponding to said graphic object, data describing a spatio-temporal arrangement and data describing the primitives of the objects which is independently stored in storage means which can be interrogated, a spatio-temporal arrangement content containing an object to be defined by such primitives comprising data designating the storage means to be interrogated in order to obtain data corresponding to said primitives.

Description

technical field [0001] The invention relates to graphic animation description technology. [0002] More specifically, the present invention proposes a method of managing a graphics scene, as well as a storage system and a receiver for implementing the method. Background technique [0003] There are currently several graphic animation representation formats. [0004] They take two main paths: [0005] - One is a tree-like representation based on the spatial-temporal rangement of graphical objects, which enables precise interaction between graphical objects and sub-objects, but which also needs to be called before being so displayed Intermediate processing of "rasterization". [0006] -Another approach is a rendering mode based on a polygonal architecture and employs simple primitives to ensure fast rendering. [0007] The first approach corresponds to graphics description formats adopted eg by W3C / SVG and MPEG-4 / System / BIFS. However, this first approach does not provide ...
