1. A method of editing MPEG digital video information signals, comprising the steps of:

  • reading a first block of information of a first digital MPEG information signal that is located around an edit point to be determined in the first digital MPEG information signal, into In internal memory of an editing apparatus;

    first outputting the first block of information from the apparatus, to an MPEG display;

    first establishing an ‘

    out’

    position in the first block of information as the edit point in the first digital video information signal;

    reading a second block of information of a second digital video MPEG information signal that is located around an edit point to be determined in the second digital video information signal, into the internal memory of the apparatus;

    second outputting the second block of information of the second digital video information signal from the apparatus, to the MPEG display;

    second establishing an ‘

    in’

    position in the second block of information as the edit point in the second digital video information signal;

    processing a portion of the first block of digital MPEG information that precedes and may include the ‘

    out’

    position, and a portion of the second block of digital MPEG information that follows and may include the ‘

    in’

    position, into a composite block of digital MPEG information;

    third outputting the composite block of digital MPEG information from the apparatus to the MPEG display; and

    recording at least a portion of the composite block of digital MPEG information that was displayed, onto a record carrier;

    and in which the record carrier includes a data recording portion divided up into fixed size fragment areas;

    the processing means encodes the digital MPEG blocks to be recorded into a channel signal of sequential channel blocks; and

    the size of the channel blocks of information satisfies the following relationship;
