This Recommendation specifies that the recipient of metadata from an original source intended to be distributed on cable networks is the cable head-end or cable distribution center of the controlling multiple service operator (MSO). The MSO can then use and add information to metadata and then, selectively redistribute metadata to cable customer services based upon designated metadata profiles.
