Abstract
Abstract During recording of an MPEG information signal on a record carrier (40), transport packets (P k ) are stored in signal blocks in a track (1) on the record carrier (40). x transport packets of the MPEG information signal are stored in the second block sections (SB) of y signal blocks, where x and y are integers, x≧1 and y>1, more specifically, y>x. Further, third block sections (TB) are present in one or more of the second block sections in the y signal blocks of a group for storing additional information, which additional information relates to the specific application of recording and reproducing the MPEG information signal on/from the record carrier.
