Abstract
A method and apparatus for the insertion and transport of advertisements in a digital environment, including methods for directing advertisements (ads) at subscribers and substituting advertisements in a program stream with targeted advertisements. The insertion methods are based on synchronous, plesiochronous, or asynchronous techniques. These methods may operate at constant bit rates or at available bit rates. An ad manager is used to select targeted advertisements, and dynamic ad linking is used to substitute an advertisement in a program stream with an alternative targeted advertisement.
