Scrambling: An electronic security technique used to render a TV signal unviewable unless it is processed and restored by an authorized decoder or descrambler.

Service Area [Boundary]: As a definition specific to MSOs (cable company), a service area boundary typically follows municipal boundaries and/or zip code boundaries, whereby the MSO is legally obligated through franchise agreements to provide "services" to the entire municipality. Most telcos network follows the Public Utilities Commission Boundaries, not municipal boundaries.
This has created multiple legal battles between MSO and LECs attempting to provide Video services. The Warren study will have all the cable/MSO boundary information. Traditionally, Service Area Boundaries were called Hubs which generally followed city boundaries (geographical data), within the hubs there are nodes (equipment). These nodes typically feed 400 to 1000 "homes passes." Finally, an arbitrary "grid" (geographical) data was overlaid on the homes passed. Therefore, every customer had a hub, node and grid number.
Given the cumbersome nomenclature and its limited usefulness, it has been abandoned. GIS
Share: The percent of television households tuned to a particular program or category of programming.
SHVA (Satellite Home Viewer Act): Federal law (section 119 of the Copyright Act) which gives direct-to-home satellite distributors such as DBS a compulsory license for the retransmission of broadcast television programming. The SHVA will expire on December 31,1999, unless extended by Congress.

Switch: A mechanical or electronic device for making, breaking, or changing the direction flow of electrical or optical signals from one side to the other.
Syndicated Exclusivity (SYNDEX): Federal requirement that cable systems black out syndicated programming from distant signals (out-of-town television stations) for which a local broadcaster has exclusive contractual rights. For example, cable operators cannot import “I Love Lucy” as part of a distant TV signal if a local broadcaster has purchased the syndication rights for that program in its market. (The FCC eliminated this requirement in 1980 and subsequently reimposed it in 1990.)
System: Facility that provides cable service in a given geographic area, comprised of one or more headends.
