Abstract:
A continuous recording system comprising:a real-time encoder for converting an analog video signal inputted from a video camera into digital video data in a real-time manner and transmitting;a video server, having a plurality of storing devices, for storing the inputted digital video data into said storing devices in a real-time manner and transmitting the digital video data read out from said storing devices to a terminal apparatus for reproducing an image; anda long time recording terminal apparatus having a long time recording processing unit for storing the digital video data sent from said real-time encoder into said storing devices while sequentially switching said plurality of storing devices of said video server, thereby continuously recording said digital video data,wherein said long time recording processing unit operates such that:a recording preparation to a specific recording apparatus is requested to said video server on the basis of a recording start instruction;an encoding of said real-time encoder is started on the basis of a notification of completion of the recording preparation from said video server, and while receiving the transmitted digital video data, said digital video data is stored into said storing devices of said video server;a predetermined switching interval time of the recording apparatus is monitored, at a stage where said switching interval time approaches, the recording preparation to a next recording apparatus is requested to said video server, and a recording preparation completion state which can be switched is accomplished; andat a time point when reaching said switching interval time, a storage destination of said digital video data is switched from the storing device in which the data is at present being stored to another storing device in the recording preparation completion state.
