A modified video codec for MBMS applications

ABSTRACT

Multimedia Broadcast Multicast Service (MBMS) is currently being standardized by the 3GPP. The MBMS services will enable new class of applications with efficient use of spectrum. MBMS also poses a new set of requirements on video coding and delivery. In this paper we present a short overview of MBMS and a video codec designed for MBMS. The proposed video codec addresses the two key issues in video delivery over MBMS: 1) error resilience and 2) resource adaptive playback. We show that the proposed codec is simple to implement on low-resource terminals such as mobile phones and outperforms MPEG-4 SP coding under lossy conditions.
