A multimedia signal processing system utilizes an easily manipulated, low-cost storage and display system that allows the user to view a television program and instantly review previous scenes within the program. The invention also allows the user to store selected programs while simultaneously watching or reviewing another. A versatile system architecture enables providing the invention in multiple configurations, each adapted to receive input signals from a different source. At the highest level, the system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. Thus, several configurations are provided, each one requiring only minor system board modifications. The system architecture thus simplifies the design and manufacturing challenge presented by producing units to serve different markets, such as digital satellite, digital cable and analog cable.

A surveillance apparatus continuously records imaged data from a camera into a circular buffer in a local memory. When a record signal is received, the system records the video stream that was recorded before the record signal was received, and the video stream that is recorded after the record signal was received. The recorded segment is then write-protected, so that the surveillance apparatus does not overwrite the recorded segment. The recorded segment could then be sent to a remote memory via a wireless connection to free up local memory for future recording sessions.

An object of the present invention is to realize an imaging device and recording control system in which the usability thereof can be improved dramatically. In an imaging device configured to output imaging data that is obtained as a result of imaging of an object, and a recording control system, the imaging device comprises a control means for recognizing a controlled state of an external recording device when a communication is enabled with the recording device through a communication means conforming to a predetermined transmission method and an input means for allowing the recording device to execute an application needed for a recording operation obtained by controlling the recording device, and the recording device records the imaging data obtained through the communication means when the application is executed by means of the input means.

Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. The system receives a digital stream and simultaneously processes the digital stream for display and stores the digital stream on at least one storage device. The system further simultaneously processes a previously recorded digital stream for display while processing the digital stream for display.
