"DSS Contract No. 0ST83-00078." Includes bibliographical references. "This report is concerned with proposals for error correction schemes appropriate for broadcast teletext systems. Error correction can greatly improve the performance and extend the range of such systems. Since a broadcast system will be used in both rural and urban settings a variety of error types are to be expected and an error correction system must be able to deal with independent and a spectrum of burst error events. Moreover, code should place a minimum demand on the teletext decoder in terms of cost, memory, hardware. The code should be quickly decodable to permit on-line decoding or minimum delay off-line processing. Furthermore, the code rate must be kept high to satisfy the efficiency demands of the system operators"--Introduction and results, page 1-1. Error-correcting codes (Information theory) Canada.
