Abstract: In this paper, we introduce a novel video codec and distribution standard developed by the Moving Picture Experts Group (MPEG), called network-distributed media processing (NDMP). Compared with existing video codec and distribution standards, which assume one encoder and one decoder, NDMP inserts a media processing unit, based on network entities, which implements media processing in a distributed manner, between the encoder and the decoder. NDMP has advantages in the following aspects:(1) it reduces the need of storage resources in the network. (2) it reduces the occupation of the bandwidth in backhaul network and (3) it reduces Round-Trip Time of remote media processing.
