The functions of subscriber wined television receivers in this new setting are examined and the details of set-top converters are closely scrutinized. Also explored are augmented one-way and two-way services which will require such added equipment in the home as a camera, microphones, digital devices, sensors, printers, and tape recorders. Lastly, characteristics of the augmented home teizminal are examined in an attempt to identify the demands which the new services may place upon the cable systems.
