Abstract
(EN)
A signal generation method comprises: a step SD11 for determining, as a method for transmitting a visible light signal from a transmitter, either one of a single frame transmission method for transmitting data as one frame or a multiframe transmission method for dividing data into multiple frames and transmitting the multiple frames; a step SD12 for, when the multiframe transmission method is determined, generating partition type information indicating the type of data to be transmitted and adding the partition type information to the data to be transmitted to thereby generate joined data; a step SD13 for dividing the joined data into multiple data parts to thereby generate multiple frames including the multiple data parts, respectively; and a step SD14 for generating the visible light signal by adding a preamble to the head of each of the multiple frames.
(FR)
L’invention concerne un procédé de génération de signal qui comprend : une étape SD11 pour déterminer, en tant que procédé pour émettre un signal de lumière visible à partir d’un émetteur, l’un ou l’autre d’un procédé de transmission de trame unique pour transmettre des données sous la forme d’une seule trame ou d’un procédé de transmission de trames multiples pour diviser des données en de multiples trames et transmettre les multiples trames ; une étape SD12 pour, lorsque le procédé de transmission de trames multiples est déterminé, générer des informations de type de partition indiquant le type de données à transmettre et ajouter les informations de type de partition aux données à transmettre pour générer ainsi des données conjointes ; une étape SD13 pour diviser les données conjointes en de multiples parties de données pour générer ainsi de multiples trames comprenant les multiples parties de données, respectivement ; et une étape SD14 pour générer le signal de lumière visible par ajout d’un préambule à la tête de chacune des multiples trames.
