Abstract
Examples are provided for apparatus and methods for video encoding and decoding. An encoder apparatus for encoding a picture into a data stream is configured to: subject a transform of a block of the picture to quantization to obtain a quantized transform; determine a zero-quantized portion of the quantized transform; determine at least one noise parameter providing noise information on the transform within the zero-quantized portion; signal the quantized transform and the at least one parameter.
