A spatial multiplex number controlling method and others wherein streams can be separated for each of receivers and the transmission efficiency can be improved. In a receiving apparatus, a PER is calculated from a history of CRC test results per stream multiplex number. A reception quality and an offset corresponding to the calculated PER are fed back to a transmitting apparatus. The transmitting apparatus assigns, based on the fed-back reception quality and offset, the streams, thereby controlling the stream multiplex number.

La présente invention concerne un procédé de contrôle du nombre de multiplexages spatiaux et autres dans lequel des flux peuvent être séparés pour chacun des récepteurs et où l'efficacité de la transmission peut être améliorée. Dans un appareil de réception, on calcule le PER à partir de l'historique des résultats de test CRC pour chaque nombre de multiplexage du flux. La qualité d'une réception et le décalage correspondant au PER calculé sont renvoyés à un appareil de transmission. L'appareil de transmission affecte les flux en fonction de la qualité de réception et du décalage renvoyés, ce qui permet de contrôler le nombre de multiplexages du flux.
