The Effect of Word Distribution on the Error Management of Digital Television Recorders

In the SMPTE and the European Broadcasting Union, groups are working toward a single format for digital television tape recording. This paper discusses the relative benefits of different methods of distributing words, both on the tape and between one head and another. The use of every head on all parts of the picture is shown to be beneficial. This conclusion is reached both from considerations of head clogging and of variations of performance between one head channel and another. Formats with one group of clustered heads are the only formats which automatically result in all heads being used equally on all parts of the picture, ensuring freedom from head-banding.
