Abstract
The invention relates generally to convergent multimedia systems, and more specifically, to effective switching between different services in a television set-top box (STB) environment. Two services which are often supported by STBs are regular television, and Internet over television (IoTV) services. Most STBs only have the resources to support one service at a time--thus, to toggle between a television program and an email service, the user must close the television program window and launch a new software application for the email service. Opening and closing software applications is a slow process, and the state of IoTV applications is lost when they are closed. The invention provides a method of operation for a STB which responds to toggle commands by switching the users display between the television and IoTV services, but keeping the IoTV service operable and its state current even when the user is viewing the television service.
