Abstract: The present invention relates to an intelligent central surveillance server system and controlling method thereof, which are capable of determining whether or not a preset event occurs based on a sensor sense signal and/or a motion sense signal and transmitting/receiving image information obtained in the occurrence of event through a serve-client system. The intelligent central surveillance server system comprises: a sensor unit configured to sense and transmit a sense signal; a camera unit configured to pick and transmit video information; and a digital video transmitter configured to determine whether or not a preset event occurs, based on the sense signal and/or the video information, and transmit first video information and first list information related to the first video information on the basis of the point of occurrence of event when the preset event occurs.

Abstract: A method and apparatus for encoding multi-channel video signals is disclosed. In order for multiple of input channels to share hardware resources, one input channel is selected and multi-channel input video signals are stored through memory block switching. Multiplexer (1), video decoder (3), and digital video multiplexer (9) participate in selecting one input channel and memory block switching section (17) switches input and restoring frames to and/or from memory (27). For stabilizing frame rate under the conditions of multiple input channels, input channel sequence is determined by synchronization signal separator (7) and priority detection and channel switching section (13). In accordance with the present invention, multi-channel video signals are encoded into MPEG by using the conventional single channel MPEG encoder (15).
