Changes to definitions of terms in clause 3.1 (from clause 13.3 of TR 103 708)
- A new term "continuous real-time conversation" is proposed to be added to replace the tentatively misleading "two-way voice communication" used in clause 6.2.1.1:
continuous real-time conversation: type of organization in conversation and discourse where one participant's contribution is made available to other participants while it is being made
- In the definition of the term "Real-Time Text (RTT), note 1, it is proposed to change the allowed END-TO-END delay from 500 ms to 1 s, in order to align with the requirements for good conversational text (T2) from Recommendation ITU-T F.700 [i.33], and with the allowed 500 ms delay BEFORE TRANSMISSION responsiveness clause 6.2.4:
NOTE 1: Users will perceive communication as continuous if the delay between text being created by the sender and received by the recipient is less than 1 s. However, the actual delay will be dependent on the communication network.
The results of these proposed changes can be seen in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
