摘要:
A memory card (110) extracts a session key (Ks) by decoding data provided on a data bus (BS3). Encryption means (1406) encrypts a public key KPcard (1) of the memory card (110) based on the session key (Ks) and sends it to a server over the data bus (BS3). Each memory (1412) stores data, such as a license key (Kc) encrypted by a unique public key KPcard (1), a license ID, and a user ID, received from the server, and stores content data ([Dc]Kc) encrypted by the license key (Kc) and supplied over the data bus (BS3).

A system for monitoring standard broadcast signals, comprises a device for receiving the broadcast signals, a user-operable selection device for inputting criteria identifying program content of interest to the user, a database for storing data representing the criteria, and a recognition device for generating from the broadcast signals a program data stream representative of the program content. A comparator compares the program data with the stored data, and an output device carries out a predetermined action, such recording a segment of the program, when the program data matches the stored data. The system will, for example, activate a window on a multimedia PC when preselected program material is present in the broadcast signals.

A method and system for ordering content includes a content processing system and a device in communication with the content ordering system. The device displaying a link corresponding to content and accessing a content ordering system by selecting the link. The content processing system enables a content recording request. A user receiving device receives the content associated with the link in response to the content recording request and stores the content in a memory.

Apparatus and methods for including a code (68) having at least one code frequency component in an audio signal (60) are provided. The abilities of various frequency components in the audio signal to mask the code frequency component to human hearing are evaluated (64), and based on these evaluations an amplitude (76) is assigned to the code frequency component. Methods and apparatus for detecting a code in an encoded audio signal are also provided. A code frequency component in the encoded audio signal is detected based on an expected code amplitude or on a noise amplitude within a range of audio frequencies including the frequency of the code component.

Provided is a receiving apparatus, including: a stream receiver unit configured to receive a broadcast transport stream; a partial-transport-stream recorder configured to create a partial transport stream from the received broadcast transport stream, and to record the partial transport stream in a recording medium; an event generating section configured to generate an event, the event relating to the received broadcast transport stream; and a private-descriptor inserting section configured to create a private descriptor, the private descriptor being information on the generated event, and to insert the private descriptor in a section of the partial transport stream.

Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy WID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction 20 with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

Disclosed herein is an information processing apparatus comprising a receiver and capable of judging what kind of content is being input. In step S1, the receiver receives a content that is broadcast in real time. When outputting the received content to a different apparatus connected to the receiver illustratively via a digital bus, the receiver supplements the output content with a broadcast bit set to indicate the real-time nature of the broadcast content. On detecting the broadcast bit set in the input content, the different apparatus judges that the content in question is being broadcast in real time. If no broadcast bit is found set in the input content, the different apparatus judges the content to have been reproduced from storage. This invention applies illustratively to receivers for receiving TV broadcasts.
