CA 2683583

A digital broadcasting system for transmitting/receiving a digital broadcasting signal and a data processing method are disclosed. First program table information and second program table information, which has an identifier different from an identifier of the first program information, are multiplexed and transmitted. The first program table information describes main service data throughfixed reception channel, while the second program information described mobile service data through mobile reception channel. Thus, a broadcast receiving system can receive and output the mobile service data by parsing the second program table information.

L'invention porte sur un système de radiodiffusion numérique destiné à transmettre et recevoir un signal de radiodiffusion numérique, et sur un procédé de traitement des données. Selon l'invention, de premières informations de table des programmes et de secondes informations de table des programmes, qui possèdent un identificateur différent de celui des premières informations de table des programmes, sont multiplexées et transmises. Les premières informations de table des programmes décrivent des données de service principal via un canal de réception fixe, tandis que les secondes informations de table des programmes décrivent des données de service mobile via un canal de réception mobile. De cette manière, un système récepteur de radiodiffusion peut recevoir et sortir les données de service mobile en analysant les secondes informations de table des programmes.
