PURPOSE: A stand-alone type digital video and audio storage system including an audio channel is provided to compress, store, reproduce and transmit digital video and audio signals and to perform real-time monitoring function, real-time remote monitoring function, real-time video conferencing function and video/audio data downloading function. CONSTITUTION: A stand-alone type digital video and audio storage system including an audio channel receives analog video and audio signals from a monitoring camera and microphone through a video/audio input unit(104). The system digitalizes the received video and audio signals to display the digitalized data, encodes and stores the video and audio signals when an event such as motion is generated. The system decodes the video and audio signals to display. The system connects to a network to transmit digital video and audio signals composed of transport streams to a remote place. The system includes a network processor and a remote connection program to enable remote monitoring, camera control and file transmission.
