摘要

An apparatus for recording in a recording medium a flow of packaged data that includes a plurality of video programs, each of said video programs comprising respective packets of said data flow, whereby the programs are multiplexed in the flow of data, each of said programs having a respective package identification information in the packages thereof and each of said programs including images I that provide intra-image encoded information and P images and B images that provide inter-image encoded information, the apparatus comprising: distinguishing means (13) for analyzing the packets of the data stream in order to detect each program of said plurality of video programs based on the package identification information and to distinguish each of said programs Video according to package identification information incl This data flow and a table included in said data flow, the table included in said data flow providing a map between each of the video programs and the package identification information; detection means (14) for analyzing the packets of the data flow in order to detect information in them that means points of said video programs in which a reproduction can begin after a random access reproduction; obtaining means (14) for obtaining position information indicative of a position of each of said random access points detected in said data flow; generation means (15) for generating a random access information table comprising a respective list of said position information for each package identification information cited, whereby the lists correspond to respective different video programs and are distinguished from each other by the package identification information; and recording means (20) for registering said data flow within a file of said recording means, characterized in that the detection means are operative to detect the random access points of said data flow from the table included in said data flow in combination with the images I of each of the programs identified by the package identification information, said respective list of said position information includes a presentation timestamp indicative of a playback time and an address information corresponding in said registration means for said respective random access point and said registration means (20) are operative to register said random access information table within a separate file with respect to the data flow file of said registration means ( twenty-one).
