Abstract

The invention concerns a method for recording of digital video and audio dataflow characterised in that, the recording is performed on a medium (201) organised in the form of logic blocks in series and comprising a recording and reading head. The method comprises steps which consist in: recording data in one block out of two starting from a first block; following the triggering of data reading, alternatively reading a previously recorded block while proceeding with the recording in the block coming after the read block. The invention also concerns a digital television receiver set using said method.
