Convention Paper

A Digital Audio System for Broadcast and Prerecorded Media

Authors: Todd, Craig C.; Gundry, Kenneth J.

AES Convention 75 · Paper 2071 · March 1984

Abstract

The requirements for a digital audio system to be used for broadcast or prerecorded media differ from those for recording in that the major economic consideration is the cost of the playback circuitry. This fact has been utilized in the digital audio system to be described. The system offers high quality sound at a relatively low data rate (on the order of 200-350 kbits/sec). No precision components are required in the decoder minimizing cost. The performance, cost, and data rate advantages are achieved by placing more sophisticated circuitry in the encoder. Applications being pursued include DBS, cable, and terrestrial broadcast systems.
