Patent ID: 7999704

Claim:
A for data communication, which method comprises at least a first data compression performed before transmission, which method further comprises at least a first data decompression, which is performed after the data is received, the data compression and decompression being performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver, in which receiver the symbols are decompressed by use of the specific hash table, whereby characterized in that the specific hash table is performed as a hash table array, which hash table array generates symbols comprising at least a hash count and a parity check, in which hash table array the parity check comprises generating of a data string, which data string is compared with a parity stored in the hash table, where if both parities are the same, the data model returns the count in the hash table element for transmission, and where, if a zero count is returned indicating that the data string is not valid in the hash table, no transmission is performed.
