1 Type of Question

Task-oriented Question that should eventually result in a Recommendation.

2 Motivations

Current Recommendation J.120 specifies the transmission protocol and system configuration for distributing sound and television programmes over the Internet, i.e. "webcasting". It specifies the operations necessary to adapt audio and video bit streams to the Internet Protocol and the functional characteristics associated with this system. However J.120 is for rather narrow-band webcasting services using PSTN or ISDN PRI.

The webcasting Question from 1998, "Requirements and methods for sound-programme and television 'webcasting' services" covers distribution of sound and television programmes on the Internet. It is necessary to create a new Question which covers wide effective utilization of IP with regard to the high-speed, quasi-error free and interactive nature of cable television networks. New transmission and control protocols, codecs and multiplex systems should be studied for high-speed and real-time IP streaming packets transmission over cable television networks.

3 Questions

- What type of protocols need to be applied to "High-Speed Webcasting" using cable television networks?

- What codecs and multiplex systems are required for "High-Speed Webcasting"

4 Expected results and anticipated target dates

Depending on the contributions that will be received, and on progress in the work of the appointed Rapporteur, it is expected that the Question will result in a first draft Recommendation by 2002.

5 Relationships

Cooperation with ITU-T Study Group 13 and 16, and with ITU-T Study Group 6 is needed in the study of this Question. Communication is also to be ensured with IETF through ITU-T Study Group 13.
