A method and system for reducing channel changing time in multicast media, that can include the steps of receiving at least one of a plurality of available channels from a service provider at a residential gateway through a network, ranking the popularity of at least one of the available channels at a ranking engine connected to the residential gateway, and requesting to receive a number of the channels available from the service provider at the residential gateway based on the ranking. The rank is at least partly based on the data stored in the database.
