Technical Overview of the CD-I Format

Authors: Pohlmann, Ken C.

AES Conference: 5th International Conference: Music and Digital Technology · Paper 5-020 · May 1987

Abstract

CD-I (Compact Disc - Interactive) is a product-specific application of the CD-ROM (Compact Disc - Read Only Memory) format, which in turn is based on the CD-DA (Compact Disc - Digital Audio) standard. Rather than store specific data on a CD-ROM, or music on CD-DA, CD-I permits storage of a simultaneous combination of audio, video, graphics, text, and data, all functioning in an interactive manner. CD-I is thus a multi-media extension of CD-ROM. Because CD-I players will reproduce conventional CD-DA discs, CD-I is also an upscale CD-DA system. The CD-I format defines both hardware and software standards, and integration of functions. To provide flexibility in CD-I applications, different levels of audio fidelity, video resolution, and color coding are available, longer playing times are achieved by dividing the disc into channels, and executable object code provides for real time interactivity. Physical interleaving of data ensures synchronized presentation of different data types. CD-I also provides two data forms, for both maximum storage bandwidth, and extended error detection and correction.
