Abstract:
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; andrecording 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:SFA/2.ltoreq.size of a block of the channel signal<SFA,where SFA equals the fixed size of fragment areas of the record carrier.
