System and method for delivery and updating of real-time data

Abstract

A system, method and computer program for receiving real-time data from a content provider and delivering it to a user terminal while using the minimum amount of communication bandwidth possible. This real-time data may take the form of any frequently changing data such as stock prices. The user logs on the system and specifies a portfolio or stocks he is interested viewing. The user may also select active keys which are to be continuously observed. Upon receipt of the real-time data from the content provider, the system, method and computer program determine whether the real-time data has changed from the last update. If no changes have occurred to the real-time data values or the real-time data is not associated the currently active keys then there is no real-time data downloaded to the user. Only if there is a change in real-time data values associated with active currently active keys will the real-time data be transmitted to the user terminal. Further, this system, method and computer program may communicate to any possible user terminal no matter what size screen since the position of each changed real-time data value is specified based on screen size the user terminal is using. Therefore, a user may monitor continuously changing real-time data values while using a mobile device such as a digital cellular phone.
