Abstract
A sequence of data (b) entered into a compression device is selectively either compressed or not compressed, then supplied by the compression device as compressed or uncompressed data (b°, s°). A status information item (S) in a sequence of supplied data (b° , s°) is overwritten by the compression device through at least one value of the supplied data before being supplied. The sequence of supplied data (b°, s°) is composed of compressed and uncompressed data (b°, s°).
Claims13
A method for compressing data, comprising the steps of:
- a sequence of data (b) entered into a compression device is selectively either compressed or not compressed, then supplied by the compression device as compressed or uncompressed data (b°, s°), where
- a status information item (S) in a sequence of supplied data (b°, s°) is overwritten by the compression device through at least one value of the supplied data before being supplied,
- wherein the sequence of supplied data (b°, s°) is composed of compressed and uncompressed data (b°, s°), and
- wherein the status information item (S) indicates whether or not segments of the supplied data (b°, s°) assigned to the status information item (S) are compressed.
1 more element
A method for decompressing a sequence of partially compressed supplied data (b°, s°), comprising:
- a status information item (S) has been inserted in the sequence of supplied data (b°, s°), where the status information item (S) is used by a decompression device to decompress the supplied data as compressed data, or not to decompress the supplied data as uncompressed data, and to output data in the form of the decompressed or the uncompressed data (b*, s*) to a data processing device.
