A video and audio recording apparatus includes a recording medium that records base data therein and a control unit that starts and stops destructive editing in response to an instruction to start and stop destructive editing received through an operation unit. When part of the base data is deleted, the control unit writes, using management information for managing a physical area of the base data in the recording medium on the per predetermined recording unit basis, information indicating that the physical area in which the deleted part of the base data was recorded is defined as a reserved area on the per predetermined recording unit basis to the management information. When the edit data is input in response to the instruction to start editing, the edit data is overwritten into the physical area managed using the management information and defined as a reserved area on a preferential basis.

Video and audio recording apparatus and editing method

In an editing apparatus; overwriting data used for insertion editing on base data, which is segmented into each picture including data having a predetermined unit of data amount X, and includes variable-length encoded real data, is variable-length encoded; each picture is sequentially obtained as a target picture, and regarding the target picture, if an amount of the overwriting data is equal to X, the overwriting data is handled as insertion data as it is, otherwise, insertion data is created by adding stuffing data to the overwriting data so that the amount of the overwriting data can be equal to X; a filler having the same amount as a filler of the base data is added to the insertion data having the same total amount as the real data; and the resultant insertion data is added onto the base data.

A video recording system is provided in which reliability of information supplied from a video camera to control recording and the like is improved when video being obtained by a video camera is recorded in one or more VTRs. In the video recording system, the video camera multiplexes: control information to control the VTR in accordance with an operational status of an operation unit of the video camera and a video signal from an imaging unit of the video camera, and transmits the result to the VTR as a transmission serial digital signal. The VTR separates the video signal and the control information from the serial digital signal and controls a video recording system of the VTR based on the control information.

In an editing apparatus and an editing method where the editing operation is enhanced in easiness and accuracy, a marker RSM or GSM is detected by a fast access to a tape-shaped recording medium, material data read out according to the detection of the marker from the tape-shaped recording medium are registered onto a given file, then material data registered on the fileare displayed and an edit list of material data is made out using the displayed material data, so that the operation of making out an edit list can be simplified without making an access to material data of the tape-shaped recording medium

In changing or otherwise handling sequential videotex codes composed of geometric codes representing individual image areas as respective geometric drawings and also characteristic codes representing attributes of the geometric drawings, the order of transmission of the geometric codes and characteristic codes is supervised on an order table and a characteristic code table is provided for supervising the characteristic codes, with correction or rearranging of the videotex code data being effected on these tables. In the case where the videotex codes are to represent an input color image, a histogram of the frequencies of occurrence of all colors represented by color data for each input color image is produced and a predetermined relatively small number n of colors having the highest frequencies of occurrence, either in the histogram as a whole, or in divisions of the histogram, are selected and each image area has assigned thereto color data representing the one of the n selected colors closest to the actual color of the image area in question.

Image forming apparatus and method

An image signal encoding system wherein image signal is directly taken in through video camera, changed to digital data, broken down into PDI basic patterns, and then converted into NAPLPS code automatically. The taken-in image signal is divided into a plurality of areas and the information amount of the image signal is reduced for adequate encoding after taking in the image signal. Usually 'POLYGON' command is used as the NAPLPS code.
