Disclosed is a video recording apparatus capable of performing long-recording at higher density and certainly associating the video data with additional data. Video images from a plurality of video camerasare captured by a multiplexerwhile sequentially being switched. A frame compositing unitforms reduced video images by reducing the captured video images and generates a composite video image by displaying the reduced video images on divided parts. A CPUgenerates additional data related to the reduced video image on each divided part and records the composite video image and additional data onto the same video cassette tapewhile maintaining the correspondence between each reduced video image and additional data. By recording video images from the plurality of video cameras at higher density, long-recording can be realized. By using the additional data, a desired reduced video image can be retrieved from the recorded composite video image and the retrieved reduced video image can be analyzed.

Video recording apparatus and method, and centralized monitoring recording system

Another operation such as searching for information recorded is achieved without interrupting recording of input information. A CPU controls a VCR block so that input information is recorded on a video tape when the video tape is ready for recording. When the video tape is not ready for recording, such as when searching for information recorded on the video tape is performed, the CPU controls a RAM block so that input information is temporarily recorded in RAM. When the video tape shifts from a state of not ready for recording to a state of ready for recording, the CPU controls the VCR block and the RAM block so that the information recorded in the RAM is transferred to the video tape for recording.

Continuous recording apparatus for surveillance

It is an object of the invention to suppress burden on a device portion and a tape recording medium occurred through recording of intermittent data. A CPU ( ) controls a RAM block ( ) and a VTR block ( ) to record input information on a RAM ( ), and transfer intermittent data included in a predetermined amount of input information recorded on the RAM ( ) to a video tape ( ) to be recorded while continuing recording of input information on the RAM ( ) when the input information recorded on the RAM ( ) reaches the predetermined amount. As described above, the recording operation of intermittent data in the VTR block ( ) is suppressed to minimum and burden on the device portion and the video tape ( ) in the VTR block ( ) occurred through recording of intermittent data can be suppressed while performing excellent intermittent recording.

Intermittent data recorder, intermittent data recording controller, intermittent data recording method, and intermittent data recording control method

Video information can be smoothly played back without producing a frame jump even if an externally-instructed playback velocity changes every moment. The present invention comprises a hard disk for storing video information D corresponding to n frames therein, two buffer memories A and B for respectively inputting video information D corresponding to continuous m frames therein and outputting the video information D while changing writing and reading, means for reproducing the video information D , and a CPU for alternately writing video information D into the memories A and B based on the playback velocity so that video information D corresponding to several frames overlap, determining a slow reproducible playback velocity range according to the video information D , correcting the playback velocity so as to fall within the playback velocity range, and thereafter reading the video information D into the reproducing means from the memories A and B based on the corrected playback velocity.

Recording and reproducing device and method of reproducing video information on variable-velocity basis

A data transfer and recording apparatus capable of transferring data recorded on a hard disk to a magnetic tape of a VTR apparatus and recording the same there, wherein four channels of audio data reproduced from the hard disk are recorded on the magnetic tape by recording two channels of the audio data A,(,) and A,(,) on a two-channel audio sector of the magnetic tape, then recording two channels of the audio data A,(,) and A,(,) via a flap portion. At this time, the video data V(,) is repeatedly recorded via the flap portion.
