Summary

ITU‑T Recommendation J.285 defines requirements of IP-based material transfer from remote sites to a broadcast station controlled by the broadcast station side. The requirements are based on the generic requirements defined in ITU-T Recommendation J.284 with the analysis of several use cases which are also described in this Recommendation.

To satisfy the requirements, this Recommendation also defines the architecture for programme material transfer in synchronization with pull operation. The architecture is only relevant to transfer of file-based materials such as computer files. That is, transfer of unfiled materials such as signals from equipment like cameras and microphones are not taken into account in this Recommendation. The architecture also enables synchronized transfer of multiple files simultaneously, which offers the opportunity for the receiver to switch receiving files from one to the others according to an edit decision list (EDL).
