Abstract: When content data are distributed from an information center via a predetermined communication line to a terminal apparatus loaded with a recording medium recorded with its identifier and prepaid information, the information center manages the usable remaining amount of money in the recording medium loaded in the terminal apparatus and updates this usable remaining amount of money every time content data are distributed. Further, if the usable remaining amount of money is smaller than the price of the content data distributed from the information center, the information center instructs the terminal apparatus to load another recording medium having a usable remaining amount of money sufficient to cover the content data to be distributed. Still further, a remaining recordable capacity of a recording medium loaded in the terminal apparatus is transmitted to the information center, and the information center compares the remaining recordable capacity with the size of the data content to be distributed.

Abstract: The encoded contents of a piece of delivered information is accompanied by an applicable time data indicating a specific time period for authorizing a particular mode of utilization. When a request for utilizing the contents is issued in an information utilization apparatus, it determines if the current time agrees with the time authorizing the requested utilization by referring to the time data annexed to the encoded contents. If the request is acceptable at the current time, a set of processing steps is carried out for decoding the encoded contents and other necessary operations. Thus, an information access control method can be adapted to have flexibility in setting charges and access requirements for the contents of information that can change the value and the mode of utilization with time.

Abstract: A method of purchasing a soundtrack associated with A/V content. When A/V content is purchased by download or otherwise, the user is provided with an option to purchase or store the soundtrack. In one embodiment, the purchase of the motion picture secures usage rights to the soundtrack while another embodiment requires separate purchase of the soundtrack. In either case, the user is enabled to store the soundtrack as a separate file after having purchased rights to do so. The soundtrack is then stored, in some embodiments with digital rights management or copy protection to limit the number of copies that can be made of the soundtrack. The motion picture has a Table of Contents (TOC) indexing the soundtrack portions of the audio content of the motion picture to enable extraction of those portions of the motion picture forming the soundtrack.

Abstract: One embodiment of the present invention provides a system that facilitates remotely configuring a device across a network. The system operates by receiving configuration information at the device from a remote system across the network. Next, the system encrypts this configuration information using a device key, which is locally stored at the device and is different from keys associated with other devices. The system then configures the device by storing the encrypted configuration information in a non-volatile configuration store associated with the device. In this way, the encrypted configuration information contained in the non-volatile configuration store cannot be used with another device. In one embodiment of the present invention, receiving the configuration information involves using a secret key, which is locally stored at the device, to decrypt the configuration information received from the remote system.

Abstract: 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.

Abstract: A method for providing authentication, authorization and access control of software object residing in digital set-top terminals creates a fingerprint (“signature”) for each software object, associates each fingerprint with a service tier, encodes each association and creates an association table containing the information and downloads the association table to the digital set-top terminal. In addition, the method utilizes an entitlement management message, sent to each set-top terminal, indicating what software objects the set-top terminal may utilize, and provides a system routine at the digital set-top terminal that is invoked whenever software object is about to be utilized. The entitlement management message contains the access rights given to a particular set-top terminal, which must match the software object's access requirements for the software object to be utilized.

Abstract: A billing system for use in a chargeable program broadcasting is capable of reliably billing a subscriber for program reception while preventing unauthorized reception thereof. A receiving terminal includes a primary terminal 100 and a secondary terminal 150. The primary terminal 100 receives a compressed video signal and confirms by an error checker 113 thereof whether there is a transmission error and bills, by a billing device 114 thereof, the receiving subscriber on the basis of an error information and a program information, etc., separated from the video signal by a separation circuit 112. The compressed video data is time-axis multiplexed with a terminal identifying code and a key signal and transmitted to the secondary terminal 150. In the secondary terminal 150, a bill for the subscriber is confirmed by the terminal identifying code and the compressed data is decoded by a decoder circuit 166 thereof.

Abstract: To prevent unauthorized reception, storage, copying and reproduction of digital media objects it is defined in addition to a scrambled broadcast format a scrambled storage format which is different from the broadcast format. A user's terminal equipment cannot receive, store or reproduce protected objects without a key which is advantageously a bit sequence stored on a portable memory medium and which can be different according to the type of use it gives entitlement to. To prevent the storing and later reproduction as such of data in the broadcast format, a time stamp is included in the broadcast format representing the time of broadcasting. A playback device cannot reproduce a broadcast-format object if the reproduction time differs from the time stamp included in the broadcast format. The reproduction time is advantageously read from a real time clock of a portable memory medium.
