Patent ID: 7971215

Claim:
A method for managing streams, the method comprising: associating different program map tables with devices of different users that are scheduled to filter, at a certain point of time, streams that form a same program; wherein the different program map tables reflect streams that should be filtered by devices of the different users; wherein each program map table out of the different program map tables lists packet identifier (PID) values of multiple streams that form a program; sending to the devices of the different users, in response to the association, at least one of: (a) association information that represent the association between different program map tables and the devices of the different users; and (b) association information that maps different Program Number values to the devices of the different users; and updating the different program map tables so that during another point in time the different program map tables describe different programs that comprise at least one different stream; wherein each of the programs comprises multiple streams that are multiplexed together.
