A dramatic change brought about with the advent of digital television is the conversion from an analog to a digital representation of the television spectrum. In the new digital world, data is easily and efficiently passed through from its source to destination in an unaltered fashion. As a result, datacasting is rapidly achieving parity with video and audio services in digital television systems.Sources of data are expanding (Internet, streaming video and audio services, digital archives) along with the public's demand for more and varied information-based products. The wide and easily accessible "data pipe" provided by digital television has placed data on a similar level of importance with video and audio services to the home. As a result, datacasting has become the newest source of revenue-producing services for digital television programmers and distributors. This paper explores the distribution and delivery of Internet Protocol (IP) data services, and the role of digital satellite and digital cable systems in the delivery of these services from the programmer to the viewer.
