Abstract
Methods, systems and apparatus are provided for a service provider to stream user-customized information. In an embodiment, the user-customized information includes tickers, advertisements and other types of user-specific information. Users can register for categories that interest them, from an available set of categories. The service provider can then stream the user-customized information on the basis of registration information. A parent service provider streams a main event and gives the service provider control of streaming the user-customized information during still periods of the main event. The service provider can also stream tickers, based on the registered categories, during the main event.
