ITU-T J.150 SPANISH-1998 Operational Functionalities for the Delivery of Digital Multiprogramme Television, Sound and Data Services Through Multichannel, Multipoint Distribution Systems (MMDS)
The scope of this Recommendation covers the operational functionalities for digital (multiprogramme) signals distributed by MMDS systems, used as extensions or alternatives to CATV networks, possibly in frequency division multiplex with existing analogue signals. Detailed specifications are contained in Annexes A, B, C and D. Annex A is based on work done in Europe and should provide a suitable basis for future developments. Annex B is still under study. Annex C is based on work done in Japan and should provide a suitable basis for future developments. Annex D is based on VSB modulation scheme and on work done in North America. It should provide a suitable basis for future developments. It should be noted that this Recommendation deals with downstream signal delivery only; the needs for interactive services requiring both downstream and upstream (return) channels are beyond the scope of this Recommendation.
