Abstract:
(EN) A delivery data transmission device (100A) is mounted on a train and transmits delivery data. When the distance between the delivery data transmission device (100A) and the next arrival station at which the train arrives next becomes equal to or less than a threshold value, a redundancy level determination unit (115A) determines, on the basis of a congestion level of radio communication channels in the area around the next arrival station, a redundancy level of an erasure-correction code to be applied to the delivery data. An encoding unit (116B) subjects the delivery data to erasure-correction encoding at an encoding rate corresponding to the redundancy level determined by the redundancy level determination unit (115A).
(FR) L'invention concerne un dispositif de transmission de données de distribution (100A) qui est monté sur un train et transmet des données de distribution. Lorsque la distance entre le dispositif de transmission de données de distribution (100A) et la station d'arrivée suivante au niveau de laquelle le train arrive ensuite devient égale ou inférieure à une valeur seuil, une unité de détermination de niveau de redondance (115A) détermine, sur la base d'un niveau d'encombrement de canaux de communication radio dans la zone autour de la station d'arrivée suivante, un niveau de redondance d'un code de correction d'effacement à appliquer aux données données de distribution. Une unité de codage (116B) soumet les données de distribution à un codage de correction d'effacement à un taux de codage correspondant au niveau de redondance déterminé par l'unité de détermination de niveau de redondance (115A).
(JA) 配信データ送信装置(100A)は、列車に搭載され、配信データを送信する。冗長度決定部(115A)は、配信データ送信装置(100A)と列車が次に到達する駅である次到達駅との間の距離が閾値以下になった際に、次到達駅周辺における無線通信チャネルの混雑度に基づき、配信データに適用する消失訂正符号の冗長度を決定する。符号化部(116B)は、冗長度決定部(115A)により決定された冗長度に対応する符号化率で配信データを消失訂正符号化する。
