Zusammenfassung:PROBLEM TO BE SOLVED: To implement a clock transmission in a multiplex transmission system independently for each individual line.SOLUTION: A multiplex transmission system 1 includes: a multiplex transmitter 100 by which signals s1-sn for each line including data and clocks, respectively, are multiplexed and transmitted; and a demultiplex receiver 200 by which the multiplexed signals are received and demultiplexed into data for each line and the signals s1-sn are reproduced and outputted. In the multiplex transmitter 100, a multiplex line signal TDMS including information 22 identifying clocks LCLK1-LCLKn of the signals s1-sn and data d1-dn of the signals s1-sn is generated and transmitted to the demultiplex receiver 200 by a specific clock REFCLK. In the demultiplex receiver 200, the data d1-dn and the information 22 identifying the clocks LCLK1-LCLKn are acquired from the multiplex line signal TDMS, the clocks LCLK1-LCLKn are reproduced, and the data d1-dn are outputted by the clocks LCLK1-LCLKn for each line.SELECTED DRAWING: Figure 3 【課題】多重伝送システムでのクロック伝送を個別回線ごとに独立して実現する。【解決手段】多重伝送システム1は、各々データおよびクロックを含む回線ごとの信号s1〜snを多重化して送信する多重送信装置100と、多重化された信号を受信して回線ごとのデータに分離し、信号s1〜snを再生して出力する分離受信装置200と、を有する。多重送信装置100は、信号s1〜snの各クロックLCLK1〜LCLKnを特定する情報22と、信号s1〜snの各データd1〜dnと、を含む多重回線信号TDMSを生成し、特定のクロックREFCLKで分離受信装置200に送信する。分離受信装置200は、多重回線信号TDMSからデータd1〜dnおよび各クロックLCLK1〜LCLKnを特定する情報22を取得してクロックLCLK1〜LCLKnを再生し、データd1〜dnの各々を回線ごとのクロックLCLK1〜LCLKnの各々で出力する。【選択図】図3
