Abstract
A method of recording digital video signals, particularly color television signals, in such a manner that type drop outs and other errors can be corrected, comprises arranging the words in a manner on a recording medium such that the information used to replace an error comes from a part of the recording medium which is statistically well separated from the error. This is achieved using a plurality of recording tracks. Apparatus for carrying out the method comprises a plurality of shift registers for storing the digital signals, and means for reading out the signals in the desired manner. The preferred method of error correction is to arrange signals from the same line of video raster.
