Advances in Video and Audio Coding Techniques
20.04.2010 14:30-15:30
Digital media find wide applications in recent years. Well-know examples are mp3, DVD, digital camera and digital TV. After a quick overview of the audio and video coding principles, we focus on the coding methods and standards developed in the past 5 years. Two types of scalable video coding techniques, interframe wavelet and layered DCT, emerged during the MPEG standard competition. The latter became the MPEG scalable codec standard. Recently, 3D video products are aggressively growing. One step further, the free-viewpoint video seems to be the next MPEG standardization item. Audio coding techniques also advance fast in the past a few years. A scalable version of MPEG audio is MPEG-4 Scalable to Lossless coding; also, a very efficient parametric spatial audio codec was standardized and called MPEG Surround. In this talk, we will describe briefly our research work on these topics.
