BBC was also responsible for the development of the NICAM stereo standard.

NICAM-like audio coding is used in the HD-MAC system.

The aim is to obtain, with a video recorder, a NICAM sound carrier television signal which circuit-wise is simple and is free from distortion.

NICAM takes care of the games rated 3 and 7, whereas the VSC Rating Board reviews the 12, 16 and 18 ratings.

Some of these analogue channels have in addition to its 6 MHz audio carrier, a NICAM carrier behind.

The phase output (ap) feeds the DQPSK partial decoder of the ''NICAM'' decoder (nd) and supplies the frequency-modulated audio signal through the differentiation stage (dt).

A second memory (106, 108) temporarily stores companded A-channel and B-channel data of a previous frame in a format other than an interleaved format according to NICAM standard requirements.

NICAM takes care of the games rated 3 and 7, whereas the VSC Rating Board reviews the 12, 16 and 18 ratings.

We can also check the effect of the digital on the NICAM of the precedent channel or even shift the signals as required.

PEGI 3 and 7 ratings are undertaken by the Dutch NICAM (Netherlands Institute for the Classification of Audiovisual Media.)

The front-end section is configured for operating with a system clock (68) that is integer divisible such that the system clock can be used by both the NICAM processor (82) and the front-end section (80, 84).

The NICAM sound carrier is therefore recorded in a deeper layer (S2) with second magnetic heads (K2) in frequency multiplex with EM sound carriers (T1, T2) at lower frequency.

Local series and movies are usually broadcast in NICAM stereo, although sometimes an audio narration track for

The used television signal comprises a video signal (401), an analog sound signal (402), and a digitally coded sound signal (403) such as NICAM as an additional service to the video and analog sound signal.
