摘要： Electronic steganographic techniques can be used to encode a rights management control signal onto an information signal carried over an insecure communications channel. Steganographic techniques ensure that the digital control information is substantially invisibly and substantially indelibly carried by the information signal. These techniques can provide end-to-end rights management protection of an information signal irrespective of transformations between analog and digital. An electronic appliance can recover the control information and use it for electronic rights management to provide compatibility with a Virtual Distribution Environment. In one example, the system encodes low data rate pointers within high bandwidth time periods of the content signal to improve overall control information read/seek times.

摘要： A barcode is formed on an optical disk. The optical disk is provided with a control data area and an identifier for indicating the presence or absence of the barcode in the control data area. A beam pattern if focused on a reflective film of the optical disk in an information signal region on which the data is recorded. Information is provided for making the barcode. The information is PE-modulated so that a width of a mark of the barcode is half or less than a period of the barcode marks. The optical disk is rotated to form the barcode.

摘要： A method and apparatus for adaptively controlling the presence of copy protection signals in a video signal depends upon the scene content of the video signal during an upper portion of a display of the video signal. Thus, in the upper portion of the scenes, wherein picture information would be noticeably altered by a hooking process the copy protection process is deactivated or effectively reduced to eliminate or reduce the hooking or tearing effects. The adaptive control of the copy protection improves the playability performance of copy protected video signals on a very small minority of television receivers which display a small hooking or tearing characteristic in the upper portion of the display of the copy protected video signal.

摘要： A cable television system provides conditional access to services. The cable television system includes a headend from which service “instances”, or programs, are broadcast and a plurality of set top units for receiving the instances and selectively decrypting the instances for display to system subscribers. The service instances are encrypted using public and/or private keys provided by service providers or central authorization agents. Keys used by the set tops for selective decryption may also be public or private in nature, and such keys may be reassigned at different times to provide a cable television system in which piracy concerns are minimized.

摘要： In a fee charging system for video information, scramble signals including video information and charging information can be recorded on a recording media such that the signals are read later therefrom. The recording of the scramble signals is free of charge. In an operation to reproduce original unscrambled video signals from the signals read from the media by a recording and reproducing apparatus, the charging information is detected to conduct a charging process. Consequently, although the scrambled signals may be freely copied onto another recording media, the charging process is executed for each copying operation. First charging information and second charging information other than the first charging information are arranged with the video information. The video information includes first video information as main video information and second video information. The first charging information is added to the first video information, whereas the second charging information is added to the second video information. A charging process is executed by a charge processing unit according to the charging information. When the second charging information is detected, the charging process is accomplished according to the second charging information in the charge processing unit.

摘要： The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is not open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

摘要： A wireless mobile unit includes a voice encoder circuit that receives an analog voice signal and creates digital voice data representing a user's voice. The mobile unit receives an encryption key entered by the user, typically on the keypad or through a voice recognition circuit, and stores the encryption key in a storage device. An encryption circuit encrypts the digital voice data using the encryption key. A transmitter then modulates the encrypted voice data onto an RF signal and transmits the RF signal to a base station in a wireless network. The base station uses the same encryption key to decrypt the signal before transmitting it to another base station or mobile unit. Signals transmitted from the base station to the mobile unit are encrypted and decrypted using a user-selected encryption key in a similar manner.
