  • Publication number: 20070271581
    Abstract: An information distribution and processing system contains a remote site, a sender and a receiving apparatus. The remote site contains a first set of digital data. The sender delivers a second set of digital data to the receiving device. In one embodiment of the present invention, the receiving device contain a timing device for automatically receiving the second set of digital data at predetermined times. The second set of digital data contains a first set of displayable data, a second set of displayable data, at least one non-displayable symbol, and at least one linking reference associated with the second set of displayable data. If desired, a user can select the second set of displayable data. The associated linking reference is sent to the remote site. The associated linking reference is used by the remote site to search for the additional information, and returns the requested information to the user.

  • Publication number: 20070107031
    Abstract: An information distribution and processing system contains a sender and a plurality of processing units. The sender delivers a set of digital data, without receiving a request signal, to the plurality of processor units. The set of digital data contains a first set of displayable data, a second set of displayable data, at least one non-displayable symbol, and at least one linking reference associated with the second set of displayable data. If desired, a user can select the second set of displayable data. The associated linking reference is sent to a database. The database contains additional information. The associated linking reference is used by the data to search for the additional information, and returns the requested information to the user.

  • Patent number: 6789198
    Abstract: A method for delivering digital data to a plurality of processing units is disclosed. A plurality of portable memory device containing a first set of digital data is distributed to the plurality of processing units. The first set of digital data is unencrypted and comprises a content portion and an identification label. At least one of the processing units sends the identification label to a remote station. The remote station then encrypts a second set of digital data and delivers the encrypted data to the requesting processing unit. The requesting processing unit can decrypt the encrypted data, and combine the decrypted second set of data with the content portion.

  • Patent number: 6314574
    Abstract: An information distribution system encodes a first set of digital data on a plurality of portable read-only storage devices. Additional information is stored in a database that is accessible by using a bi-directional channel. The first set of digital data contains a plurality of special displayable terms, a first non-displayable symbol, a plurality of linkage references, and a second non-displayable symbol. A user can select at least one special displayable term. The linking reference associated with the selected special displayable term is sent to the database via the bi-directional channel. The database uses the linking reference to search for information, and returns the resulting information to the user.
