ITU-T J.703 PDF

The scope of this Recommendation is the i-3 interface, identified as the control interface for IP transport for enhanced broadcasting defined in [ITU-T J.700] and in Figure 1 below, that enables the service client in the customer's network to send requests for content and application transport using IP technology to the IPTV service functions in the operator's network. Examples of IPTV content and application to be requested through the i-3 interface include digital video and audio programme content, including the metadata describing the programme content, and applications to be presented or executed at the service client. Examples of IPTV requests include requests for broadcast or video on demand (VoD) content, requests to manipulate VoD content delivery (pause, play, rewind, etc.), and requests to record content for later viewing.
