Abstract: Since 1988, Public Broadcasting Service (PBS) has embarked on a modernization plan to deliver to it's member stations, multiple digital video, audio, and data signals, via new satellite systems. The Ku-band transponders and ground stations have been in operation. The Technical Operations Center (TOC) at Braddock Place in Alexandria, VA continues the transformation to digital video and audio operations for improved quality of service and increased number television program channels. Those program channels plus auxiliary data are compressed with General Instruments DigiCipher™ I equipment with a planned upgrade to DigiCipher™ II technology early next year. This paper will provide a discussion of the systems, operations and enhancements for delivery of digital program services and information data, from the PBS facilities to the nation's public television stations.
