Advances in broadcast digitization have been rapid in Japan since the broadcasting satellite (BS) digital broadcast services commenced in December 2000. It requires that the receiver, which may also be connected to appliances using a Home Network, has an inbuilt HDD for storing interesting programs. However, it is difficult to guarantee QoS level on a 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, a new scalable MPEG transmission method is required. For this we propose a Scalability method allowing for Impairments Propagation (SIP), which takes into account the impairments propagated to other frames due to the loss of a macroblock in a given frame. In this paper, we introduce the SIP technique, analyze it mathematically, and evaluate its performance.
