摘要： A recording medium and a picture display system in which multiplexed data recorded on a recording medium sold only in a specified territory or multiplexed data broadcast for a specified territory can be displayed only on a decoding reproducing system sold or installed only in such territory. Multiplexed data including a territory code are recorded on a recording medium. This territory code is compared to the inner territory code in the decoding device and, if the territory code of the recording medium includes the inner territory code of the decoding unit, the recording medium is decoded and reproduced. In the multiplexed data, allowable period data is stated in association with the territory code. This allowed period is compared to the date of a calendar generator in the decoding unit. If the date of the calendar generator is comprised within the allowed period, the recording medium is decoded and reproduced.

摘要： Information searching apparatus and method and a transmission medium with which an edition point can be detected simply from coded data without decoding all the coded data. Particularly, in the present invention, an audio signal is divided into plural blocks on the frequency axis every predetermined time (every predetermined frame), and a scale factor serving as a floating coefficient and a word length are coded as a parameter. In a recording medium are recorded coded audio data and the parameters together with the number Ni of the parameters. In a high-speed searching operation, the parameter number Ni is extracted, and a frame for which the parameter Ni varies stepwise is detected as the edition point.
