  Digital cable - Wikipedia, the free encyclopedia
Digital cable is a term for a type of cable digital television that delivers more channels than possible with analog cable by using digital video compression.
Digital cable also enables two-way communication, enabling services such as the ability to purchase pay-per-view programming without the use of a phone line.
Digital cable signals are often worse than analog signals, due to compression artifacts in both the image and sound.

 Telecommunications Training - Digital Transmission Video Course
Since computers communicated in a digital format and the telephone network was analog, the transmitted signals had to be converted by devices called modems.
Now they are extending the digital signals all of the way into businesses and homes by converting the telephone networks from "telephone service" to "digital service." These new networks will provide you with end to end connections of binary or digital bit streams at various speeds.
Digital services are making this easier than ever because you only need to meet one common interface regardless of the type of information you transmit.

 Convergence Green Paper: Working Document   (Site not responding. Last check: 2007-10-15)
Digitisation of networks and the increasing integration of computer processes and memory into such devices were the key factors underlying such changes.
At the same time, concerns were expressed by incumbent telecommunications operators and by some broadcasters that any increase in the number of jobs due to new technologies was unlikely, in the short-term, to offset continuing job losses in their traditional activities as they adapted to greater competition and the introduction of these new technologies.
Digitisation, on the other hand, since it would drastically reduce spectrum scarcity in broadcasting and lead to an increased number of TV channels, was seen as leading to extra demand for premium content.

Maybe homes and workplaces, transportation systems, and the emerging digital telecommunications infrastructure can be reconnected and reorganized to create fresh urban relationships, processes, and patterns that have the social and cultural qualities we seek for the twenty-first century.
Digital telecommunications infrastructure is now beginning to follow the old electric and telephone wires, and in some cases to piggyback on the existing copper.
Satellite telecommunications systems are not affected by terrain at all, and can deliver services even more economically to areas with very low population densities and teledensities (telephone lines per hundred residents).22 Older geosynchronous satellite systems had large but limited service footprints, and mostly focused their capacity on densely populated areas.
