1. A method for providing an event notification, comprising: maintaining an event description dictionary comprising one or more event descriptors; associating content with a selected event descriptor, wherein the event descriptor does not include the content and is configured to at least describe or characterize the content; splitting the event descriptor into a first portion and a second portion; transmitting the first portion of the event descriptor on a notification channel to a client, the notification channel being an overhead channel that allows for transmission of short information messages, wherein the notification channel is not used for transmission of the content; and transmitting the content and the second portion of the event descriptor on a different channel distinct from the notification channel.
