US 5,181,229 A · Data transmission arrangement using a statistic coding, a transmitter and a receiver section suitable for such an arrangement

Abstract

A data receiver, and transmitter/receiver combination, for transmitting data using statistic coding. A data transmitter transmits statistic encoded data representing successive sample series in a form having a variable number of bits followed by two self-synchronizing codes, each self-synchronizing code including a suffix formed by a codeword or a concatenation of codewords. A data receiver for use with such a transmitted signal includes a correction circuit which can store at least one sample series, and a write counter for forming address codes defining locations of samples to be stored in the storage portion of the correction circuit. Preferably a sequencer provides a window signal which validates the output of a synchronizing signal detector in a time interval when the synchronizing word will probably be received.

Dependent claims

An apparatus for encoding an image signal comprising a plurality of line signals into sequences of digital codewords, said apparatus comprising:

a) means for converting a line signal into a series of digital samples;
b) means, coupled to said converting means, for statistically encoding each of said digital samples so as to form a series of first codewords;
and
c) means, coupled to said encoding means, for forming a sequence of digital codewords by appending at least two statistically coded self-synchronizing codewords to the end of said series of said first codewords.
