You want H.222.0 (not H.222)
H.222.0 = ISO/IEC standard 13818-1

H.221
Frame structure for a 64 to 1920 kbit/s channel in audiovisual teleservices

H.222
[Withdrawn] Frame structure for 384-1920 kbit/s channels in audiovisual 
teleservices (Merged with ITU-T H.221 in 1990)

H.222.0

associated audio information: Systems

H.222.1
