If you have a cable modem, chances are that it will be built according to specifications from Study Group 9.

Now a focus of the group is the development of standards that will allow the more efficient deployment of interactive video for cable TV operators.

Recent work has includes a standard (ITU-T Recommendation) that allows content providers to roll out value-added interactive video services to any network without modification. iTV allows viewers of a football match for example, to display data on a player while a match is in progress. Previously, proprietary or country-specific standards forced content providers to develop different product versions for each market.

Additionally Study Group 9 has produced standards aiming to reduce theft of service, a key concern for cable operators and also Recommendations that cover Internet over cable, VoIP over cable and videoconferencing over cable.​​
