Full Description

a) Study the embedding of SBV videotex protocols within the ITU-T T.120 series of Recommendations, paying attention to X.25 and H.221 being side by side; b) In conjunction with STCs TE4 and TE10, and taking into account the decision of TC TE (12/94) on initial priority setting, establish a priority list of possible scenarios identified in DTR/TE-01050. For the top scenarios of the above mentioned list: i) Define and describe the different services corresponding to these scenarios; ii) Specify the associated interactive protocols; iii) Define the interworking units (if required by the scenario. c) Study the possible constraints of the possible scenarios on the hardware and software of audiovisual terminals.
