Abstract

Sont divulgués dans la présente invention, un procédé de diffusion de données, un procédé et un appareil de réception de données de diffusion et un dispositif terminal. Le procédé de diffusion de données consiste : à acquérir des données désignées pour former des paquets de données ; et à les diffuser tour à tour au moyen de différents canaux de diffusion désignés, les paquets de données étant diffusés au moyen de chaque canal transportant des informations de synchronisation différentes respectivement, chaque information de synchronisation comprenant un numéro de séquence de canal à envoyer ensuite, et les paquets de données sont reçus par une extrémité de réception, de telle sorte que l'extrémité de réception commute un canal de réception actuel vers un canal ayant le même numéro de séquence de canal.
