Scalable MPEG video transmission method considering impairments propagation on home network environment

Digitalization of broadcast advances rapidly in Japan since the broadcast satellite (BS) digital broadcast services began in December 2000. It is a requirement that the receiver has a built-in HDD, for storing interesting programs, which may be connected with appliances over the home network. However, it is difficult to guarantee QoS on the home network composed of heterogeneous sub-networks. Therefore, for the purpose of an efficient and appropriate transmission of a video stream such as MPEG over the home network, it is required to develop a new scalable MPEG transmission method. For this reason, we propose a scalability technique considering impairments propagation (SIP), which takes into account the impairments propagated to other frames due to the loss of a macroblock in a given frame. We introduce the SIP technique, evaluate its performance and give a system model using SIP.
