  • Publication number: 20140192928
    Abstract: A transmission system includes a data sending device that sends data at a first speed and a data receiving device that receives, by using a plurality of clocks having different phases, data that has been sent by the sending device at the first speed. The data sending device sends, to the data receiving device, some of the data, which is sent at the first speed, at a second speed that is lower than the first speed. Furthermore, in accordance with determination as to whether the content of the received data sent at the second speed matches a corresponding portion of the data received by using a plurality of clocks, the data receiving device changes the timing at which the data that has been sent at the first speed is received.

  • Patent number: 8776148
    Abstract: In an inherited communication management apparatus, a storage unit stores viewing information relating to the content viewing state of a user of a terminal. On a request from the user of the terminal for content viewing, a requesting unit requests another inherited communication management apparatus to examine whether or not the other inherited communication management apparatus stores viewing information including information relating to interruption of the content viewing by the user. A receiving unit receives a result of the examination requested by the requesting unit. When the examination result received by the receiving unit includes the viewing information including information relating to the interruption of the content viewing, a transmitting unit transmits information relating to interrupted content based on the viewing information to the terminal of the user that has requested the content viewing.
