<p>A television sound signal processing apparatus receives a digitized delta-encoded sound signal superposed in a horizontal blanking period and a digital signal showing the standard value of the sound signal superposed in a vertical blanking period, and then compares the reference signal of this field with that or one field before, and, when the difference is greater than a predetermined value employs the decoded value of the delta encoded signal immediately before that reference signal as the standard value for the delta decoding of the sound signal,</p> |
