Abstract:
One embodiment takes the form of a method and apparatus for creating a customer-specific encryption key for encrypting digital information. The encryption key may be based on a customer number and may be associated with several devices such that the devices may encrypt and decrypt the digital information. Because each device may have the same encryption key, the encrypted data may be encrypted by a first device, transferred from the first device to a second device and decrypted and read by the second device. Thus, encrypted digital information may be shared between devices that generate a customer-specific encryption key from a common customer number. In one embodiment, the customer-specific encryption key may be utilized by a set-top box of a television system to encrypt and decrypt a digitally recorded television program.
Abstract:
A content receiver receives an update to a memory unit contained therein utilizing data stored in a data card inserted or incorporated into the content receiver. The content receiver dynamically generates a matrix code based on the updates received in the memory and on information uniquely identifying the content receiver. The matrix code is transmitted to a content display device for display, and a matrix code reader detects the displayed matrix code and transmits information contained within the matrix code to a content provider for updating a user's account associated with the updated content receiver. The content provider may transmit a message to the content receiver for display on the content display device indicating the update to the user's account. The content provider may transit a similar message to the matrix code reader.
Abstract:
A process of displaying program information on a viewing screen may include: providing an electronic programming guide, the electronic program guide divided into timeslots containing program information; displaying program information from the displayed timeslots on a viewing screen; providing a link to additional information, the link associated with the program information of a particular timeslot; and displaying the additional information upon receiving a user input while displaying the program information of a particular timeslot. A related system may include: a client device configured to receive and display audio-visual programs; an electronic programming guide including a link to additional information associated with the program information of a particular timeslot; and a processor configured to display program information from the displayed timeslots on a viewing screen and to display the additional information on the viewing screen upon receiving a user input while the program information of the particular timeslot is displayed.
