Abstract: Disclosed herein is an information processing apparatus causing a larger number of video signals than at least one video port possessed by a processor to be input to the processor through the video port, the information processing apparatus including: a multiplexed video frame creation section creating multiplexed video frames in such a manner that each of the multiplexed video frames has the video signals multiplexed therein for input to the processor through the video port and includes a sufficiently large number of pixels so that frame images represented individually by the video signals may be pasted onto each multiplexed video frame in non-overlapping relation to one another; and a multiplexing block multiplexing the video signals in such a manner that the frame images represented individually by the video signals are pasted in non-overlapping relation to one another onto each of the multiplexed video frames created by the multiplexed video frame creation section.

Abstract: 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 cameras 101 are captured by a multiplexer 103 while sequentially being switched. A frame compositing unit 1 forms 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 CPU 3 generates 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 tape 7 while 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.

Abstract: The present invention aims at simplifying configurations of devices compliant to a plurality of simultaneously imaged video signals. A plurality of imaging means 101 and 102 obtains a plurality of imaged video signals P1 and P2. These signals are selected at a vertical synchronization timing (104) to generate one system of composed video signal Pmix0. Compression means 105 compresses the composed video signal Pmix0 to record or transmit it. Decompression means 107 decompresses a compressed and composed video signal Pmix2 which is reproduced from a recording medium or is received. A video decomposition process can recover an original plurality of systems of video signals simply by selecting the signals at the vertical synchronization timing (109). An interpolation process is performed for a field that is lost due to the field-based selection during composition.

Abstract: 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.

Abstract: 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 (7) controls a RAM block (3) and a VTR block (4) to record input information on a RAM (32), and transfer intermittent data included in a predetermined amount of input information recorded on the RAM (32) to a video tape (44) to be recorded while continuing recording of input information on the RAM (32) when the input information recorded on the RAM (32) reaches the predetermined amount. As described above, the recording operation of intermittent data in the VTR block (4) is suppressed to minimum and burden on the device portion and the video tape (44) in the VTR block (4) occurred through recording of intermittent data can be suppressed while performing excellent intermittent recording.

Abstract: Video information can be smoothly played back without producing a frame jump even if an externally-instructed playback velocity changes every moment.

Abstract: 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 A1(1) and A2(1) on a two-channel audio sector of the magnetic tape, then recording two channels of the audio data A3(1) and A4(1) via a flap portion. At this time, the video data V(1) is repeatedly recorded via the flap portion.
