Abstract

In a networked client/server system, live presentations can be streamed from an encoder or other server to a client computer. Additionally, information describing the presentation is registered with a search server. This information is made available for user searches only for as long as the information properly describes the live presentation. When the information no longer describes a current live presentation, the information is no longer available for searching.

Claims

receiving information identifying a live presentation; and

making the information available for searching only during a duration of the live presentation.

2. A method as recited in claim 1, wherein the receiving comprises receiving information identifying a live presentation scheduled to occur in the future.
