    "abstract": "The National Commercial Broadcast Networks' program origination and distribution/transmission infrastructures have gone through various technological and operational changes since the inception of the centralized Network to Affiliate interconnect systems were first developed in the 1950's. The Networks now face what is probably the most technologically challenging and far reaching change in their history—the migration to a digital distribution system. This paper will review the various technical, operational and economic/business issues that The Networks will be examining as they develop their digital migration plans. The issues will be reviewed in the context of how the distribution systems currently function and how the features and functions could operate in the digital world.",
