Abstract

1,219,680. Multiplex pulse code signalling. BRITISH BROADCASTING CORP. 23 Aug., 1968 [30 Aug., 1967], No. 38930/70. Divided out of 1,219,679. Heading H4L. The description is substantially the same as that of the parent Specification but the claims relate to the combination of an auxiliary p.c.m. signal, e.g. the associated sound signal, in the line-blanking intervals of a television signal, the digit pulses being in the form of bursts of oscillation distinguishable by phase, amplitude or by the use of different frequencies.
