Comparison of Near Video on Demand Methods for CATV (1992)
By Robert S. Burroughs and Qun Shi, Panasonic Technologies, Inc.
This paper will describe a simulation model for evaluating trade-offs between Video On Demand, (VOD), schemes and transmission methods. A statistical approach is used and the concept of a "Demand Function" is introduced. The model is then applied to the specific case of a CATV system which assumes new fiber optic architectures which use "Star" configurations from the Headend and standard coaxial "Tree and Branch" networks to the subscriber. This is similar to the architecture used by A TC in their Queens project [1]. The model is also can be used to compare the capacity of different networks, such as Telephone, CATV, and DBS, to provide NVOD services.
