TSBITU-T's main work areas
Three major items:
- IP-related issues
- IMT-2000
- Accounting rates
Other items:
- Multi-media, access networks (xDSL), optical transmission,security, numbering and addressing, inter-operabilities, IPR, etc.

TSBITU-T’s work on voice coding
7 kHz band - wideband (G.722-series)
4 kHz band - analogue
64 kbit/s - PCM, G.711, 1972
32 kbit/s - ADPCM, G.726 (1984, 1988), 1990
16 kbit/s - G.728, 1992
8 kbit/s - G.729, 1996
19
TSBITU-T’s work on still picture coding
Classic facsimile (G3, G4) T.4, T.6
B/W still pictures (JBIG) T.82, T.83
Cont. tone colour (JPEG) T.81
(lossless) (JPEG-LS) T.86
(JPEG-2000) T.800
20
TSBITU-T’s work on moving picture coding
H.261 - video coding at p x 64 kbit/s
H.262 - generic video and audio coding
H.263 - video coding for low bit rates
H.264 - improved multimedia video coding (vs. MPEG-4)
Increasing participation to SG activities, but still very low level(except for SG 3)
