The invention concerns a method for loop distribution of a plurality of data blocks corresponding to objects or fragments or aggregates of objects such as alphanumeric messages and/or screen pages and/or graphic objects integrated in pages and/or sound sequences designed to be restored by restoring means with which users are provided. The invention is characterised in that it consists in distributing the data blocks by stacking them into several stacks corresponding to different distribution priorities and in repeating the operation which consists in sampling in output of each stack a number of data blocks based on the distribution priority of said stack and in distributing the sampled data blocks, the data blocks sampled in output of each stack being, at each iteration, re-stacked in the input thereof.
A method for the loop broadcasting of a plurality of data blocks which correspond to objects or to fragments or aggregates of objects such as alphanumeric messages and/or screen pages and/or graphical objects integrated into screen pages and/or sound sequences, and intended to be restored by restoring means with which users are provided, characterized in that the data blocks are distributed by stacking them into several stacks corresponding to different broadcasting priorities and in that the operation consisting in sampling at the output of each stack a number of data blocks which is dependent on the priority of broadcasting of said stack and in broadcasting the data blocks thus sampled is repeated, the data blocks sampled at the output of each stack being, at each iteration, restacked at the input thereof.
The method as claimed in one of the preceding claims, characterized in that the number of stacks is 3 or 4.
The method as claimed in one of the preceding claims, characterized in that the data blocks broadcast have a size of less than 400 useful bytes.
The method as claimed in one of the preceding claims, characterized in that the data blocks to be broadcast are classed in order of priority of consultation, the list thus constructed is divided into K stacks with a number of substantially equal data blocks and the data blocks of each stack are broadcast with a frequency equal to or nearly equal to
The method as claimed in one of the preceding claims, characterized in that objects common to several screens are transmitted once only.
A system for loop data broadcasting comprising means for the radio broadcasting of data blocks within a given area, a plurality of portable terminals able to receive the data blocks thus radio broadcast, processing means which manage the broadcasting of said data, characterized in that said processing means implement a method according to one of the preceding claims.
