1. A transmission device for transmitting packets in a communication system, the transmission device comprising:
a transmitter; and
at least one processor coupled to the transmitter, wherein the at least one processor is configured to:
obtain source packets, wherein a source packet of the source packets comprises a packet header including a packet identifier (ID) for distinguishing an asset related to the source packet from another asset, and wherein an asset is a multimedia data entity associated with a unique ID,
drop at least one source packet among the source packets, wherein each of the dropped at least one source packet includes data related to at least one asset,
generate one or more repair symbols by forward error correction (FEC) encoding remaining source packets except the dropped at least one source packet among the source packets,
generate repair data for protecting drop information indicating the dropped at least one source packet including data related to the at least one asset, and
transmit the remaining source packets and repair packets including the one or more repair symbols and the repair data for protecting the drop information to a reception device.
