Abstract:
A reproducing arrangement (1; 14) for the reproduction of compressed data (KD) included in data blocks (DB) of a data stream (DS), each data block (DB) of the data stream (DS) including header information (HI), and the compressed data (KD) included in a data block (DB) being decompressible and reproducible independently of the compressed data (KD) included in other data blocks (DB) of the same data stream (DS), and the sequence of the data blocks (DB) in the data stream (DS) defining the sequence of reproduction of the compressed data (KD) included in the data blocks (DB), the arrangement havingdata block detection means (4) adapted to detect the header information (HI) of each data block (DB) of the data stream (DS) when the reproducing arrangement (1; 14) is in the reproducing mode, and having read means (3) for reading the compressed data (KD) included in a detected data block (DB), and having decompression means (7) for decompressing the compressed data (KD) read by the read means (3) and for supplying decompressed data (AD), and having reproducing means (8) for reproducing the decompressed data (AD) supplied, and having mode means (5, 6) for defining a normal speed reproducing mode, in which the compressed data (KD) of all the data blocks (DB) included in the data stream (DS) are read by the read means (3) and supplied to the decompression means (7), and for defining a multi-speed reproducing mode, in which only compressed data (KD) of part of the data blocks (DB) included in the data stream (DS) are read by the read means (3) and supplied to the decompression means (7).
