摘要： A voice talk system 1 comprises a voice talk apparatus 11, and a voice talk control apparatus 13 which controls a talk between a sender's user and a receiver's user. In the voice talk control apparatus 13, after voice and additional information are received via a network 14, a database is searched using the received voice and additional information as search keys to specify a receiver's user. A grouping section groups the specified receiver's user(s) together. Further, a priority setting section is provided which assigns ordinal numbers as priorities for establishing a connection, to the receiver's users grouped by the grouping section.

摘要： A scramble system of the present invention including a scramble apparatus and a descramble apparatus is applied to a recording and reproducing system or a transmission and receiving system wherein a frame of a digital video signal composed of a plurality of frames is divided into a plurality of predetermined fundamental video blocks corresponding to recording and reproducing processes. Either one of the recording and reproducing system and the transmission and receiving system executes a reconstruction process such as an interpolation process, a high speed playback process or the like. The scramble apparatus executes a scramble process on the inputted digital video signal in the identical processing manner using the fundamental video blocks in the identical position in each of the frames and generates a scrambled video signal, while the descramble apparatus effects reverse conversion of the scramble process executed by the scramble apparatus using the fundamental video blocks on the scrambled video signal generated by the scramble apparatus.

摘要： The occurrence of malfunction on the reproduction side is avoided by preventing a scrambled signal from being coincided with a reserved word in the signal when a scramble process is carried out in order to release a transmission signal to specific users. The scramble process includes at least one of methods of (1) bit-inverting specified codes of the transmission signal code by code, (2) limiting bits to be scrambled from a specified position in the transmission signal, and (3) limiting codes to be scrambled to specific codes.

摘要： A data control method includes the steps of: A) at least one of the following steps: A-1) embedding prohibition information in data, wherein copying of the data is to be prohibited; and A-2) embedding the prohibition information and N pieces of permission information in the data (N is a natural number), wherein the copying of the data is to be permitted N times; and B) detecting the prohibition and/or permission information prior to the copying of the data. In the case where the permission information is detected from the data prior to the copying of the data, at least one of the N pieces of permission information in the data is invalidated, and then the copying of the data is permitted. In the case where the permission information is not detected from the data, and the prohibition information is detected from the data prior to the copying of the data, the copying of the data is prohibited.

摘要： A scrambling apparatus has at least one of the following processing units: a signal inserting processor for inserting a dummy pattern indicating the quantization width in the compressed video data; a conversion processor for scrambling a signal specifying whether field or frame processing is used; a DCT coefficient conversion processor for scrambling a part of the code defining the DCT coefficient; an intra.sub.-- dc.sub.-- precision conversion processor for scrambling the intra.sub.-- dc.sub.-- precision signal; and an alternate.sub.-- scan conversion processor for scrambling the alternate .sub.-- scan signal. A descrambling apparatus reverses the conversion process on the video data scrambled by the scrambling apparatus to restore the video data to the original unscrambled state.
