Television Production and Content Delivery


The History Channel

In 1992, Clarendon Foundation began applying for broadcast licenses to transmit free educational television programming to accredited schools and colleges under the FCC's Instructional Television Fixed Service. The Foundation leased a portion of its channel capacity to wireless cable television operators. Under the terms of the spectrum lease, the wireless operator agreed to carry Clarendon’s instructional programming on its subscription television service, and provide to free reception equipment and service to the Foundation’s “Receive Site” schools and colleges.

In order to operate its instructional television service, Clarendon Foundation, which was located in the Washington, D. C. area, obtained programming from cable television networks featuring American history and government. This programming was transmitted on Clarendon’s licensed broadcast spectrum to accredited educational institutions that had been designated as “Receive Sites."

The free television service was branded by Clarendon as “The History Channel,” which was an original idea of Clarendon’s President, Kemp Harshman. The History Channel was registered as a federal service mark in 1992. The service mark was later assigned to the Arts and Entertainment Networks and used for its cable television channel about History.



Clarendon then registered a service mark for TV America®, a new service to produce and transmit public interest programming about American history, culture, and ideals.

The TV America® logo has been updated for the advent of digital high definition television in the United States. The stars represent video pixels of Liquid Crystal Display (LCD) screens and the stripes represent the raster scan lines of plasma television screens. (The version below is a draft that is being further refined.)

Multicast Routing Scheme


Clarendon Foundation is currently developing a content delivery service that can “multicast” video programming over the Internet. With the advent of a new processing system for the World Wide Web, referred to as “Internet Protocol version 6” (or IPv6), the net will soon become a pipeline for full screen television and streaming audio.

Most video on the Internet is transmitted with unicast routing, a single viewer downloads a file (video on demand). With the same bandwidth as a unicast on the current Internet, multicast on IPv6 will reach anyone who tunes into the stream.

The IPv6 is a disruptive technology that will have a major impact on the “brick and mortar” network television industry, and will provide access to individuals, nonprofit organizations, and small companies to dramatically expand the types of programming and interactive media content.

In an interesting note, the Arts & Entertainment Networks is re-branding The History Channel as “,” to position itself for this exciting new medium.

Clarendon Foundation has been preparing for this development for many years, and anticipates being able to take advantage of new opportunities for dramatically expanding its outreach.
