Method of and apparatus for reduction of bandwidth requirements in the provision of electronic information and transaction services through communication networks
First Claim
1. A system for providing access to data through a telecommunication network, comprising:
- a host data processor for storing central lifetime tags associated with local data elements, wherein a central lifetime tag identifies a central activation time and a later central deactivation time for an associated local data element; and
a local terminal coupled to said host data processor through said telecommunication network and includinga local computer, anda local database accessible by said local computer for storing said local data elements corresponding to said central lifetime tags,wherein said local computer is configured to receive a request to access a local data element and to provide access to the requested local data element if a current moment is included in a life span between the central activation time and the central deactivation time of the central lifetime tag associated with the local data element.

Abstract
A multimedia system for providing electronic information and transaction services that combines shared remote access to a utility database with local access to a local database. When information access is requested from an interactive multimedia player provided with the local database and coupled through a telecommunication network to the utility database, the information is first searched in the local database. If it is not found there, the request is forwarded to the utility database over the telecommunication network. Each data element is associated with a defined life span that determines an interval between the data element activation and deactivation.

7. A method for providing access to data through a telecommunication network using a central database and a local database located at a remote location and coupled to the central database through the telecommunication network, said method including the steps of:
-
a) in said central database, storing central lifetime tags associated with local lifetime elements, wherein a central lifetime tag identifies a central activation time and a later central deactivation time for an associated local data element; b) in said local database, storing said local data elements; c) sending a request from the remote location to said central database for a required data element stored in the local database; d) determining whether or not the required data element is deactivated based on the associated central lifetime tag; e) if the required data element is not determined to be deactivated, providing access to the required data element. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
