Information insertion method and system

Abstract

An information insertion method and system are provided. The method includes: determining whether an insertion interval starts when a presentation module presents information from a first information source apparatus; when the interval starts, transmitting information from a second information source apparatus, preferably a local apparatus, into the presentation module for presentation; and when the interval ends, stopping transmission of information from the second apparatus into the presentation module, so that the module stops presenting information from the second apparatus and presents information from the first apparatus, thereby preventing the problem caused by channel switching or network congestion resulting in no image on the screen or temporary appearance of a screensaver image. Therefore, the information insertion can be conducted quickly at the beginning of the interval to provide an easy way for the operators to publish information very quickly or provide potential marketing opportunities for businesses to improve economic performance.
