Abstract
Describes the design and realization of an error-correcting codec. For error protection of TV lines the realized codec utilizes a shortened (2196, 2136) BCH-code with 60 bits (2.7%) redundancy. The codec provides correction of 4 random errors or correction of one error burst up to 26 bits alternatively; 5 or 6 random errors can be detected. In the case of random errors the residual error rate after error correction is less than 10-8 even at 10-4 channel error rate.
