There is provided a relay device capable of simultaneously transmitting various additional information such as audio information, character information, and image information while suppressing the communication cost and the line use ratio without increasing the calculation cost in the decoding process. The relay device includes an encoded information analysis unit (602) which outputs transmission mode information and an additional information flag to an additional processing unit (603) and outputs an information source code of each layer to the additional processing unit (603) according to the transmission mode information. According to the combination of the transmission mode information and the additional mode information, the additional processing unit (603) performs additional processing of the additional information for the information source code of each layer. An encoded information integration unit (604) integrates the transmission mode information, the additional mode information, the additional information flag, and various information source codes inputted from the additional processing unit (603).

Dispositif de relais susceptible de transmettre simultanément diverses informations additionnelles telles que des informations audio, des informations de caractères et des informations d~image tout en supprimant le coût de communication et le rapport d~utilisation de ligne sans augmenter le coût de calcul dans le processus de décodage. Le dispositif de relais comprend une unité d~analyse d~informations codées (602) qui sort des informations de mode de transmission et un drapeau d~informations additionnelles vers une unité de traitement additionnel (603) et sort un code de source d~informations de chaque couche vers l~unité de traitement additionnel (603) selon les informations de mode de transmission. Selon la combinaison des informations de mode de transmission et des informations de mode additionnelles, l~unité de traitement additionnel (603) effectue un traitement additionnel des informations additionnelles pour le code de source d~informations de chaque couche. Une unité d~intégration d~informations codées (604) intègre les informations de mode de transmission, les informations de mode additionnelles, le drapeau d~informations additionnelles et divers codes de source d~informations entrés à partir de l~unité de traitement additionnel (603).
