摘要： A decoder comprising a microprocessor connected to a receiver of data of teletext and to a text generator for displaying information on the screen of a television receiver. Further, a CPTV-card (card pay-television) is associated with the microprocessor, this card managing the credit necessary for the purchase of emissions, for the memorization of the emissions purchased and for permitting the unscrambling of the emissions purchased by delivering to the microprocessor the input pointer in the sequence which is calculated by the microprocessor by means of the information which has been memorized as well as the information delivered by the decoder. The programs of the forecasted emissions are transmitted by the head station and memorized in the microprocessor of the decoder. Another memory of the microprocessor contains the instructions for the manipulations to be effected for selecting an emission and for purchasing it as well as for recharging a credit in the CPTV-card. A keyboard permits selection and display on the screen of the television receiver of the forecasted emissions as well as the instructions of manipulation which enormously facilitates the dialog between the user and the decoder and contributes to avoiding errors of manipulation. The decoder according to the invention operates as a guide for the user, for all operations to be effected.

摘要： A scrambling method wherein each image line (23-309) of a frame having been produced in unscrambled form before being scrambled, is given the pseudorandomly determined address (B) of the memory line in the storage memory (8) in which said image line is to be stored on reception; and wherein the moment (or the running order) for broadcasting said image line is determined so that on reception, the image line causes, because it is stored in the memory line to which it was addressed, the image line previously stored at the same address to be output to the television set at the right moment (or in the right order) so that an unscrambled picture is reconstructed.

摘要： Controlling access to a sports facility with a user-carried non-transferable data storage medium which stores access privilege data and is read by a reading mechanism upon entry to the sports facility. A data storage medium, located on the user's sports equipment near the ground, stores control data, which is read by an antenna located near the ground at the entrance to the sports facility. The access privilege data, read from the non-transferable data storage medium upon entry, is combined by program logic with the control data read by the near-ground data storage medium on entry and then memorized. Upon each subsequent entry, the access privilege data from the non-transferable data storage medium and the control data from the near-ground data storage medium are re-read by the antenna. If there is a mismatch of the memorized combined data, entrance to the sports facility is prohibited.
