Abstract: According to an aspect of the invention there may be provided a method of decoding a bitstream, the method comprising: receiving a Supplemental 5 Enhancement Information (SEI) message; parsing the SEI message to obtain an encoded bitstream, said encoded bitstream containing encoded information which is associated with information of an original signal; and, decoding said encoded bitstream to obtain decoded information which is used to reconstruct the original signal. A method of decoding is also provided as well as 10 apparatuses and a computer readable medium.

Abstract: Examples of a low complexity enhancement video coding are described. Encoding and decoding methods are described, as well as corresponding encoders and decoders. The enhancement coding may operate on top of a base layer, which may provide base encoding and decoding. Spatial scaling may be applied across different layers. Only the base layer encodes full video, which may be at a lower resolution. The enhancement coding instead operates on computed sets of residuals. The sets of residuals are computed for a plurality of layers, which may represent different levels of scaling in one or more dimensions. A number of encoding and decoding components or tools are described, which may involve the application of transformations, quantization, entropy encoding and temporal buffering. At an example decoder, an encoded base stream and one or more encoded enhancement streams may be independently decoded and combined to reconstruct an original video.
