Abstract
(EN) Provided are a re-multiplexing device, a broadcast system, a re-multiplexing method, and a program that, in the case of broadcasting broadcast data of a first resolution and broadcast data of a second resolution, enable realization of synchronous outputting. A re-multiplexing device (2) has a first re-multiplexing unit (2a) and a second re-multiplexing unit (2b). The second re-multiplexing unit (2b) inserts, at a timing corresponding to a timing of a head packet in an OFDM frame, a delay control packet which includes control information for compensating a difference in delay times between a first circuit and a second circuit. In that case, the second re-multiplexing unit (2b) generates, as the control information, an index value of a waiting time, in a transmission device (3), from a time point where the delay control packet has been received to a time when modulation processing on a packet subsequent to the delay control packet starts.
(FR) L'invention concerne un dispositif de remultiplexage, un système de diffusion, un procédé de remultiplexage et un programme, lequel, dans le cas de la diffusion de données de diffusion d'une première résolution et de données de diffusion d'une seconde résolution, permettent la réalisation d'une émission synchrone. Un dispositif de remultiplexage (2) comprend une première unité de remultiplexage (2a) et une seconde unité de remultiplexage (2b). La seconde unité de remultiplexage (2b) insert, à un moment correspondant à une synchronisation d'un paquet de tête dans une trame OFDM, un paquet de commande de retard qui comprend des informations de commande pour compenser une différence de temps de retard entre un premier circuit et un second circuit. Dans ce cas, la seconde unité remultiplexage (2b) génère, en tant qu'informations de commande, une valeur d'indice d'un temps d'attente, dans un dispositif de transmission (3), d'un moment où le paquet de commande de retard a été reçu à un moment où le traitement de modulation sur un paquet après que le paquet de commande de retard commence.
(JA) 第1の解像度の放送データと第2の解像度の放送データとを放送する場合の出力の同期を実現することができる再多重装置、放送システム、再多重方法、及びプログラムを提供する。再多重装置(2)は、第1の再多重部(2a)と第2の再多重部(2b)とを有する。第2の再多重部(2b)は、OFDMフレームの先頭パケットのタイミングに対応するタイミングで、第1の回線と第2の回線の遅延時間の差を補償するための制御情報を含むパケットである遅延制御パケットを挿入する。その際、第2の再多重部(2b)は、送信装置(3)において前記遅延制御パケットが受信された時点から前記遅延制御パケットに続くパケットに対する変調処理を開始するまでの待機時間の指標値を、前記制御情報として生成する。
