Method for decoding compressed video pictures in a video decoding device comprising a random access source of coded video pictures, a video decoder and a plurality of reconstruction buffers for storing decoded pictures, said method comprising the steps of:
- establishing an order of decoding pictures;
- commanding said video decoder to decode a picture upon availability of a reconstruction buffer.
Video decoding device comprising
- a random access source of a compressed video stream including coded pictures;
- means for selecting pictures to be decoded;
- a plurality of reconstruction buffers for storing decoded pictures;
- a video decoder for decoding coded pictures;
- means for monitoring the availability for write access of reconstruction buffers and for controlling said video decoder to decode a selected picture upon availability of a reconstruction buffer, wherein the availability of a reconstruction buffer is determined by the status of the display of a picture contained in said reconstruction buffer.
