Abstract:
A method of reproducing information comprising the steps of:dividing a series of data including a compressed video signal, a compressed audio signal, and other digital data, thereby producing a divided series of data; constructing a first data unit including a header indicative of a head of said first data unit and said divided series of data; collecting one or more of said first data unit; constructing a second data unit including a header indicative of a head of said second data unit, information indicative of a reference time, and said one or more of said first data unit; dividing time sequential data of said second data unit into one or more predetermined units of a data structure that is peculiar to a medium, thereby producing divided time sequential data of said second data unit; recording said divided time sequential data of said second data unit on said medium after performing a signal process that is peculiar to said medium on said divided time sequential data of said second data unit; reproducing said divided time sequential data of said second data unit from said medium in accordance with said signal process that is peculiar to said medium at a data transfer rate that is not less than a data transfer rate of said time sequential data of said second data unit; rearranging said divided time sequential data of said second data unit read from said medium in accordance with said data structure that is peculiar to said medium to obtain a reassembled second data unit; and outputting said reassembled second data unit as time sequential data having a data transfer rate equal to said data transfer rate of said time sequential data of said second data unit; wherein a beginning of said outputting step is delayed until a time interval since a time at which an immediately preceding outputting step was begun is equal to a difference between said reference time indicated by said information included in said reassembled second data unit and a reference time indicated by information included in a reassembled second data unit which was output in said immediately preceding outputting step.
