Abstract:
A method for iterative decoding of compressed video data streams which have a sequence of basic pictures and interpolated pictures, comprising the steps of:storing a first basic picture in a reference picture memory;storing a second basic picture in compressed form in a buffer memory;iteratively executing the following steps for a reconstruction of at least a first interpolated picture, which steps are executed iteratively for reconstruction of every interpolated picture:decompressing only a part of the second basic picture, which is required for reconstruction of a part of the first interpolated picture,storing the decompressed part of the second basic picture in a second search area memory during a time in which the part of the first interpolated picture is reconstructed, andreconstructing the part of the first interpolated picture using the first basic picture and the decompressed part of the second basic picture.
