US 2015/0189353 A1 · Scalable Data Acquisition and Accumulation in a Resource Constrained Environment

Abstract

A method of acquiring and accumulating data from a server via a network is provided. A request is transmitted for a plurality of items of data and includes at least one ingestion marker associated with the data. The at least one ingestion marker represents a last occurrence of when a change was made to the data. Data is received with a transfer protocol in response to the request. The data has at least one associated ingestion marker different than the at least one associated ingestion marker transmitted with the request. The received data and the at least one associated ingestion marker is stored in memory. The request is transmitted and the data is received and stored electronically by an electronic client device communicating with the server over the network. A system of acquiring and accumulating Electronic Program Guide (EPG) data from a web-server over a network is also disclosed.

Dependent claims

A method of acquiring and accumulating data from a server via a network, comprising the steps of:

transmitting a request for a plurality of items of data, the request including at least one ingestion marker associated with the data, the at least one ingestion marker representing a last occurrence of when a change was made to the data;
receiving data via a transfer protocol in response to the request, the data having at least one associated ingestion marker different than the at least one associated ingestion marker transmitted with the request;
and
storing the data and the at least one associated ingestion marker received during said receiving step in memory;
wherein said transmitting, receiving and storing steps are performed electronically with an electronic client device communicating with the server over the network.

A method of making Electronic Program Guide (EPG) data available to a population of set top boxes via electronic communications over a network of a service provider of terrestrial, cable or satellite digital television, comprising the steps of:

obtaining a current complete set of EPG data for a rolling window of a predetermined number of days from at least one source;
comparing the current complete set of EPG data obtained during said obtaining step to a most-recent complete set of EPG data stored in memory to identify changes in items of the most-recent EPG data stored in memory relative to the current complete set of EPG data obtained during said obtaining set, each of the items of EPG data stored in memory including an ingestion marker representing a last occurrence of when a change was made to the item of EPG data in memory;
and
updating the items of EPG data stored in memory with the changes identified during said comparing step and updating the ingestion marker associated with the items of EPG data changed to indicate that a change was made corresponding to said obtaining step;
wherein said obtaining, comparing and updating steps are performed by at least one web-server connected to the network.
