摘要： A method of managing content data and associated metadata. According to the method, the content data and the associated metadata are generated. The content data is transferred to a content host, and the metadata and usage condition data for the associated content are transferred to an electronic store. The metadata and/or the usage condition data are altered in order to form promotional data, and the promotional data is transferred from the electronic store to a customer's system. In one preferred method, the content data is encrypted with a first encrypting key before being transferred to the content host. The first encrypting key is encrypted with a second encrypting key, and the encrypted first encrypting key is transferred along with the metadata and usage condition data to the electronic store. Additionally, the encrypted first encrypting key is transferred along with the promotional data to the customer's system.

摘要： A system for tracking usage of digital content on user devices. Electronic stores coupled to a network sell licenses to play digital content data to users. Content players, which receive from the network the licensed content data, are used to play the licensed content data. Additionally, a logging site that is coupled to the network tracks the playing of the content data. In particular, the logging site receives play information from the network, and the play information includes the number of times that the content data has been played by the associated content player. Also provided is a method for tracking usage of digital content on user devices. According to the method, a license to play digital content data is sold to a user, and the licensed content data is transmitted to a content player for the user. Further, information is transmitted to a logging site whenever the content data is played by the content player or copied from the content player to an external medium so that usage of the licensed content data can be tracked.

摘要： In a data communication network wherein broadcasted transmissions include a portion uniquely identifying the content of the following transmission and wherein transmissions are repeated at predetermined intervals, a communication unit for operating within the system includes a receiver, a processor, and memory for storing data and instructions for the processor. The receiver receives transmissions over the communication network. The communication unit receives a record command from a user that causes it to record the audio/video content being broadcasted during a subsequent transmission thereof. The memory includes space for storing the program that causes the communication unit to automatically record the transmission at the time the transmission is re-broadcasted.

摘要： A method of managing keys used by a digital content player on a computer system. According to the method, digital content data encrypted with a first encrypting key is decrypted using a first decrypting key, and re-encrypted using a second encrypting key. A second decrypting key is encrypted using a third encrypting key to produce an encrypted second decrypting key. In one preferred method, an encrypted first decrypting key that was encrypted using a fourth encrypting key is received, and the encrypted first decrypting key is decrypted using a fourth decrypting key to reproduce the first decrypting key. A digital content player for use on a computer system is also provided. The content player includes a decrypter that decrypts digital content data, which was encrypted with a first encrypting key, using a first decrypting key so as to produce the content data. An encrypter re-encrypts the content data using a second encrypting key and encrypts a second decrypting key using a third encrypting key. In one preferred content player, a receiver receives an encrypted first decrypting key that was encrypted using a fourth encrypting key, and the decrypter decrypts the encrypted first decrypting key using a fourth decrypting key to reproduce the first decrypting key.
