Today, content distribution is largely conducted via satellite circuits and physical tape. In certain cases, the element of time becomes important enough that physical movement of videotape is not even considered an option. Technological advances in the development of lower-cost, higher-powered computing and digital processing devices are finding wider use in the creation and delivery of programming. With server-based (digital) content storage, delivery becomes a matter of moving bits; however, digital program content transport requires payload bit rates from 20 Mbits/sec to 270 Mbits/sec. Existing electronic, network-based content delivery systems are limited in capacity, signal performance, and flexibility. Leveraging advanced terrestrial digital networks holds the promise of removing these limitations. This paper will describe the development and envisioned uses of a unique network interface device (NID) that is expected to make content transport via advanced common carrier (ATM and SONET/SDH) communications networks as easy as making phone calls.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J17644.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ { "affiliation": "MCI Communications, Richardson, Texas 75081", "bio": "Paul Donaldson is an engineer employed by MCI since 1984 working primarily in Transmission Systems Engineering, responsible for the design and implementation of MCI's communications network. Donaldson is experienced in RF (microwave) transmission systems design and in radio and fiber-optic communications systems deployment. Other activities include measurement and evaluation of mobile radio propagation and experimentation with antenna diversity techniques. Currently, he is responsible for the development and evaluation of advanced communications technology in MCI's Transmission Network Development organization. It is within this organization that he supports the NIST/HDTV contract, leading the technical research and development of a network interface device (NID) interfacing MCI's communications network production studios and operations facilities.
