In term of conversation charging, the charging by differentiated timeslot request type together with the subscriber's usage is taken; while in term of content charging based on duration of the video together with considering transmission type (unicast or multicast) is adopted. Then, the charging formula based on this policy is established, which insures economic interest for both network operator and SP or CP in DVB-RCS.
