Abstract
This invention relates to a data recording and reproduction apparatus, and a method and a system for sending out data for preparing a log file of material codes and a sending time. The video server comprises a storage means utilizing a randomly accessible storage media, and a server controller for controlling the storage means and multiple input and output ports connected to the storage means. The input port includes a multiplexer for inserting the material code to identify video source onto compressed video signals derived from video signals fed to the input ports. Video signals with their material codes superimposed thereon are recorded as video sources on the storage means. A material code is extracted from any video signal that is reproduced, and a log file of the sending data (sending time and data including material code relating to the sent-out material) is generated.
