- Abstract
- Scalable Video Coding (SVC) is a video codec which provides various media services through scalability in variety of mobile environments. For the scalability issues of MPEG, SVC inherited MPEG expansion format and provides a high scalability by developing efficient base and enhancement layer. Since the enhancement layers of SVC can be adaptively determined by neighboring channel environment, computing power, and resolution of the mobile device, its scalability can be useful in the current heterogeneous wireless network. But, the reliable streaming video transmission can't be satisfied with only the scalability of streaming video in SVC. Thus, error concealment techniques have been introduced into SVC to reduce the quality degradation caused by transmission error. But, the traditional error concealments have still shown vulnerable to burst errors. In this paper, we show the analysis of the error concealments and introduce a new error concealment strongly robust to burst errors. And simulation result showed that proposed error concealment achieved better performance from about 3% to 8% in terms of SVC error concealment.
