The present invention relates to a composite video and audio information recording / reproducing apparatus, and more particularly, to composite video and audio information in which specific functions of a unit product such as a digital camcorder, a digital still camera, an MP3 player, a voice recorder, etc. are integrated and packaged. A recording / playback apparatus.

In general, a digital still camera (DSC) converts an image incident through a lens into a digital signal and stores it in a recording medium such as a hard disk or a memory card. These digital still cameras are highly compatible with personal computers, making it easy to edit and modify them, and transfer images taken by connecting them with external computers. In addition, since the digital still camera has the same structure as a general camera, it is easy to carry. That is, the digital still camera includes a lens device, a memory device, a signal modulator, a display device, and the like. However, such a digital still camera is mainly used for capturing still images for reasons such as the capacity of a recording medium for recording an image. That is, although it has a function to shoot some video, it is practically impossible to shoot for a long time. In particular, since there is no device for recording and playing sound together during video recording and playback, it is practically unsuitable for recording and storing and playing video. In order to satisfy this point, recording / reproducing apparatuses, such as camcorders, which record and reproduce images and sounds of a subject photographed on a recording medium such as a tape, are widely used.

The camcorder includes a lens device, a signal conversion device, a deck device for recording / reproducing the captured image, a display device, and the like. Such a camcorder mainly uses a cassette tape as a recording medium, and mounts the cassette tape on a deck device to record a moving picture. In addition, the camcorder is equipped with a microphone device and a speaker device, and can be recorded for more than 1 hour on the cassette tape. Such a camcorder also has a function of capturing still images, but is inferior to the image quality of the digital still camera described above. In addition, since a camcorder has more functions and a complicated configuration than a digital still camera, it is common that the volume is relatively large and expensive.                         

By the way, as described above, in order to utilize the functions of the digital still camera and the camcorder, it was necessary to purchase both products. Therefore, the economic burden on the consumer was much. In addition, since there is a distinctive function of each after the purchase, there is a troublesome problem to carry both products.

Therefore, in addition to the basic image processing functions of camcorders and digital cameras as described above, by adding advanced digital technologies, for example, the functions of different unit products such as MP3 players or voice recorders, various newly packaged unit products are added.

In the composite video and audio information recording / reproducing apparatus as described above, it is advantageous to digitally process the signal processing in order to perform various functions. In addition, since image data having a multi-dimensional characteristic has a lot of information unlike general data, processing of the digital image into a digitized digital image requires a large amount of data, thus requiring a high compression rate data compression technique. do.
