Philips CD-I - Introduction to CD-I

1. Introduction
1-1-1. CD-I
The Compact
Disc Interactive (CD-I) standard for the
Compact Disc offers a flexible combination of audio,
video, text and data, involving for example
database-oriented information and computer programs,
for interactive and real-time operation on essentially
self contained and easy-to-use CD-I systems, used in
conjunction with domestic audio equipment and
television receivers.
From a technical point of view, CD-I is a logical
extension of CD-ROM. And from users point of view, it
is a logical evolution of Compact Disc. It is therefore
firmly based on the well known and universally accepted
Compact Disc standard.
CD-I is based on a complete and self-contained
specification offering full disc-player compatibility
and taking into account the installed base of mass-
produced video and audio products.
The CD-I standard embraces CD-DA discs, and provides
for a world standard disc not tied to national
television broadcasting standards.
In contrast to the disc, CD-I system have to be adapted
to match the installed base of products which conform
to different national standards. CD-I systems can be
used in combination with the existing audio equipment
and modern domestic TV receivers because the standard
allows for the development of products compatible with
all national broadcasting systems.
The CD-I standard does not offer compatibility with the
video part of the CD-V standard. However, the digital
audio tracks of CD-V discs are treated in the same way
as CD-DA discs.
