Abstract
In this paper, we propose a redistribution mechanism of the content that is adapted to devices, which may have different display size and computing capabilities, in home network. The proposed system introduces a mechanism that the encrypted content compressed by H.264/SVC(Scalable Video Coding) scheme which has been standardized recently is provided to the device into a level of content suitable to each device capability. To efficiently superdistribute SVC content, this paper defines three requirements and proposes redistribution mechanism which satisfies these requirements using another licence that it is called 'Ticket'. Our system allows devices to redistribute the content freely in the domain using domain key.
