Digital rights management for the home TV based on scalable video coding

In this paper, the business model and digital rights management (DRM) solution are proposed for the home TV based on scalable video coding and convergent networks. In this environment, the TV program is broadcasted via digital video broadcasting for handheld terminals (DVB-H) to mobile phones, the access right is transmitted by Global System for Mobile communication (GSM/GPRS) channel, and the TV program can also be transmitted from mobile phones to home TV through WiFi. The typical application scenario is that the TV program with low quality (base layer) in the mobile phone can be enriched by enhancement information and shown on home TV. The business model is presented to pay for the enhancement information, and the DRM solution is proposed for solving the copyright issues in the convergence between the DVB-H broadcasting, GSM/GPRS and home network. Since few work has been done to solve this problem, the work proposed in this paper is expected to attract more researchers.
