L'unità metrica di densità di flusso magnetico uguale a uno Maxwell per centimetro quadrato.

This ITU recommendation defines an 8-bit A-law (European companding) and μ-law (American companding) PCM audio format with 8 kHz sampling used in standard telephony. G.711 audio is also used in H.320 videoconferencing.
Industry:Software
An ITU-T recommendation which embraces 7 kHz audio coding at 64 kbit/s. G.722 uses an adaptive differential PCM (ADPCM) algorithm in two sub-bands, and is widely used for news and sports commentary links.
The sound quality is normally considered inferior compared to MPEG audio coding, but has the advantage of low coding delay in comparison with MPEG. Due to the low delay, and because of the large installed base of G.722 equipment, the algorithm will continue to be in service.

This ITU-T recommendation is entitled “40, 32, 24, 16 kbit/s adaptive differential pulse code modulation (ADPCM).” It defines the conversion between 64 kbit/s A-law or μ-law PCM audio and a channel of the rates stated in the title, by using ADPCM transcoding.
Industry:Software
This ITU-T recommendation defines coding of speech at 16 kbit/s based on code-excited linear prediction (CELP). The delay of about 2 ms in G.728 is lower than other typical implementations of this type of coding.
G.728 audio is used in H.320 videoconferencing.

The same signals as RGB. The sequence is rearranged to indicate the mechanical sequence of the connectors in the SMPTE standard.
Industry:Software
The time for scanning one complete horizontal line, including trace and retrace. NTSC equals 1/15734 seconds (color) or 63.56 μsec.
