Open the CIPO recordAbstract From the Canadian patent
The disclosure relates to digital transmission systems in which information in binary form is transmitted in pseudo-random sequences so as to enable the measurement, at reception of the quality of the, transmission. The synchronization at reception is obtained by loading the shift register of the pseudo-random generator with the code contained in a shift register that receives the binary signals transmitted. This loading is done whenever an error counter reaches a value EMAX. The error counter is reset at zero whenever the number of binary signals received reaches a value LMAX. The disclosed device and method can be applied to systems for the transmission of digital television signals.
