A method for processing data by a sending entity in a broadcasting system. The method for processing data by a sending entity includes receiving, by an application layer of the sending entity, cross layer information providing quality of service (QoS) related information from an underlying layer of the sending entity, the QoS related information being based on at least one QoS related value measured in the underlying layer; and providing a multimedia service based on the QoS related information, wherein the cross layer information is exchanged by using at least one network abstraction information between the application layer and the underlying layer, wherein the at least one network abstraction information includes first network abstraction information, and wherein the first network abstraction information includes first available bit-rate information for a change ratio of a value of an available bit-rate parameter and first buffer information for a change ratio of a value of a buffer fullness related parameter.
