Call Models for Video Dialtone

Chang, Yee-Hsiang; Pitt, Daniel



Abstract: Video dialtone represents a means for subscribers to access video channels for a variety of high-bandwidth broadband interactive services. In the United States, the video dialtone network employs the concept of the level 1 and level 2 gateways to provide this access. The core function of both gateways, a function we be- lieve to be needed worldwide, independent of the U.S. regulatory environment, is to help the user select and connect to a suitable video information provider and receive a program chosen by the user. The calling and connectivity sequences that effect this are the subject of this paper. We present two different call models and discuss their advantages and disadvantages in various conditions. We also propose a signaling model compatible with emerging broadband signaling standards.
