发明名称 DIGITALES UEBERTRAGUNGSSYSTEM MIT SIGNALRATEUMSETZUNG.
摘要 <p>A digital signal transmission system which converts first digital signals having a given bit rate into second digital signals having a predetermined bit rate to transmit them. The first digital signals are written into a buffer memory at a bit rate of the first digital signals, and the written signals are read from the first buffer memory at a bit rate of said second digital signals. The reading of the digital signals is carried out with a clock signal which consists of synchronous portions that read the written signals at any time and asynchronous portions that read the written signals depending upon the condition of the written signals. The second digital signals are sent after adding a data signal to the asynchronous portions of the digital signals. A second buffer memory receives the sent second digital signals and temporarily stores them by writing the second digital signals at the bit rate of said second digital signals, and reading the written signals from the second buffer memory at a bit rate of the third digital signals, the reading of the third digital signals depending upon signals of the asynchronous portions of the second digital signals.</p>
