Definitions

  • An object of the present invention is to record, on the same medium, high-quality video information that prohibits copying and low-quality video information whose resolution and the like are limited to a level that can be enjoyed on a small display. It is to be able to copy to a small medium. For example, this mechanism makes it possible to play small media even outdoors and enjoy video information such as movies on a small display.
  • the video information (320 horizontal pixels and 240 vertical pixels) in which both the horizontal and vertical resolutions of the first video information are both halved
  • the video information is image-compressed by H.264AVC
  • the audio information is Compressed by MP3 to create the second digital data that combines both information and other information, and record it in the recording area 3.
  • the amount of the second digital data is about 1Z8 compared to the first digital data, it is easy to add the second digital data to the current DVD pre-recorded disc.
  • both recording areas are divided into an inner periphery and an outer periphery. However, both can be recorded in the same area by time division multiplexing.
  • the second video information is converted into the first video information power.
  • the second video information can be copied to various media so that anyone can enjoy it anywhere.
  • the copyright protection information readout circuit 31 reads out the copyright protection information, Veil information, and electronic transparency information contained in the video information 32 to protect the copyright. If the information does not match the Veil information or the electronic permeability information, the video signal control signal 33 controls the signal processing circuit 29 to stop supplying the video signal to the small display 30.
