Abstract: A method and device for encoding, decoding, storage and transmission of a scalable data stream to include layers having different coding properties. The method includes: producing one or more layers of the scalable data stream, wherein the layers are characterized by a coding property, and signaling the layers with the coding property such that they are readable by a decoder to determine the coding property without analyzing the scalable data stream. Also, a method of encoding, decoding, storage, and transmission of a scalable bit stream, wherein at least two scalability layers are present and each layer is characterized by a set of at least one property, such as profile, level and a set of at least one HRD/VBV parameter, that may be different from that of the entire stream, and wherein said a set of at least one property is signaled for at least one layer that is different from the entire stream, wherein signaling of said a set of at least one property may be in said scalable bit stream, in a file format container containing said scalable bit stream, or in a transmission or control protocol for transmission or control of at least one layer of said scalable bit stream.

Abstract: A method and device for error concealment in a video sequence. When there is a scene transition in the video sequence and an error occurs in a picture belonging to the scene transition, an error concealment procedure based on the type of scene transition is used to conceal the error. Information about the scene transition type is provided to a decoder in a supplemental enhancement information message. If the scene transition is a gradual scene transition, a spatio-temporal error concealment algorithm is used to conceal the picture. If the scene transition is a scene cut and only part of the picture is lost or corrupted, a spatial error concealment is used to conceal the lost or corrupted part of the picture. If a whole picture belonging to the scene cut is lost or corrupted and the picture starts a new scene, it is not concealed.
