Abstract: Disclosed is a method of restoring specific scene whose objectives are to provide a specific scene restoration system having a sufficient detection rate enough to easily detect and pick up the specific scene from a plenty number of video data, or to detect in real time such scene as those whereon specific motions exist, comprising the steps of dissecting into k×k=N blocks( where N is 100 or less, desirably an integer in the range of 9 to 36) each frame of a motion video signal wherein a series of specific scenes to be restored are contained, calculating the motion quantities in each block using the total sum of the motion vector magnitudes in each block, obtaining a Mahalanobis distance D2 for the images of said specific scenes, calculating a threshold defined by the average of D2 plus standard deviation of D2, comparing the threshold to the Mahalanobis distance D2 calculated for each frame of the motion video signal to be retrieved, and by detecting the specific scene to be obtained on condition that the Mah

Abstract: A pay program signal is scrambled in an exclusive OR circuiit by a scrambling signal (Ks) derived from a random number generator. The pay program signal is converted into a broadcasting signal by a converter. A transmission information processor alters every month, for example, the contents of an initial value signal applied to the random number generator in order to change a scramble mode. The information processor transmits, via the converter, cipher signal (Ei) for descrambling the pay program signal in, for example, the next month. The cipher signal (Ei1) is stored in a RAM of a subscriber. At this time, a memory area into which the cipher signal (Ei1) is to be stored is designated by a distribution page flag (DP) transmitted from the information processor. The information processor also designates the memory area storing the cipher signal (Ei1), by means of a reference page flag (RF), which is to be used. The key data is used as data to determine a descramble mode of the random number generator.
