Scalable Video Coding provides several levels of video encapsulated in a single video stream. In a transmission scenario such as broadcasting, this structure is quite advantageous as it can be used to address heterogeneous decoding targets with variable needs and requirements. However, this adaptability comes at a slight cost in coding efficiency when compared to single-layer coding. Based on subjective experiments, this cost is evaluated in this paper by comparing the new MPEG-4 Scalable Videodoi:10.1109/euvip.2010.5699138 dblp:conf/euvip/PitreyBCP10 fatcat:k3klgb4z7vhdni4rwdjww5dqeq
