In this paper packet loss error concealment for video sequences compressed using spatial scalability is investigated. Slice support is implemented into the JSVM reference codec of the scalable extension to H.264/AVC video coding standard. The non-normative error concealment scheme introduced in the codec is developed further, adding to it the capability to(More)
