Distributed database management system
First Claim
1. A method for terminating a service after a delay time from receiving an authorization to initialize the service, comprising:
- receiving a first authorization object from the server at the user equipment, wherein the first authorization object specifies a delay time and a service for transmission of a television viewing object; and
in response to receiving the first authorization object from the server;
retrieving the transmission of the television viewing object from the service;
initializing, at the user equipment, decoding of the transmission of the television viewing object;
determining a first time at which the decoding of the transmission of the television viewing object was initialized at the user equipment;
determining a second time based on the delay time and the first time;
determining whether a second authorization object was received from the server at or before the second time; and
in response to determining that the second authorization object was not received from the server at or before the second time, terminating, at the user equipment, the decoding of the transmission of the television viewing object.

Abstract
A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.
