Title:
放送信号の送信時刻測定装置及びその測定方法、この送信時刻測定装置を用いた送信装置及び中継装置、及び遅延時間測定装置
Document Type and Number:
Japanese Patent JP4212403
Kind Code:
B2
Abstract:
An apparatus for measuring transmission time comprises means (112) for generating a multicarrier signal, and means (116), such as a GPS receiver, for acquiring time information. Means (111,113,114,115) are also providing for determining the difference in delay times of received multicarrier signal and the output of the multicarrier generator (112). In order to calculate the transmission time, this delay is added to the reference time signal.
