BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a method for reproducing A/V data recorded on an interactive recording medium in conjunction with contents data recorded thereon or contents data provided by a contents providing server connected through the Internet. [0003] 2. Description of the Related Art [0004] High-density optical disks capable of recording large amounts of data are being widely used. The Digital Versatile Disc (DVD), which is a recording medium that is capable of recording large amounts of high-quality video data as well as digital audio data, is one example of these high-density optical disks. [0005] The DVD includes a navigation data recording area in which navigation data required for playback control of A/V data is recorded and a data stream recording area in which digital data streams are recorded. [0006] When a DVD is loaded into a DVD reproducing apparatus, the DVD reproducing apparatus first reads the navigation data recorded in the navigation data recording area and stores the navigation data in an internal memory. The DVD reproducing apparatus then begins reproduction of the DVD using the stored navigation data, thereby providing various functions of the DVD to a viewer. [0007] The development of new interactive DVDs. is being progressing rapidly. Unlike the DVD, the interactive DVD (I-DVD) contains additional contents data, which is detailed information about A/V data recorded thereon and provides the contents data through a user interface. The contents data may be recorded on the I-DVD as html files. [0008] In addition, a method for obtaining additional contents data from a contents providing server connected through the Internet while reproducing A/V data and contents data recorded on the I-DVD is under discussion. However, a method for effectively managing reproduction of A/V data and contents data responsive to a viewer's request is not yet available. SUMMARY OF THE INVENTION [0009] It is an object of the present invention to provide a method for reproducing data recorded on an interactive recording medium in conjunction with contents data provided by a contents providing server using navigation information for the contents data also provided by the contents providing server. [0010] The method for reproducing A/V data recorded on an interactive recording medium in accordance with the present invention comprises the steps of (a) receiving playback control information for the A/V data from a contents providing server and storing the received playback control information and (b) presenting the A/V data reproduced from the interactive recording medium in conjunction with additional contents data received from the contents providing server using the stored playback control information. BRIEF DESCRIPTION OF THE DRAWINGS [0011] The accompanying drawings, which are included to provide a further understanding of the invention, illustrate the preferred embodiments of the invention, and together with the description, serve to explain the principles of the present invention. [0012] In the drawings: [0013] FIG. 1 illustrates an interactive optical disk reproducing apparatus in which the present invention may be advantageously embodied; [0014] FIG. 2 illustrates the relationship among an A/V data stream, contents navigation information, and contents data files in accordance with the present invention; and [0015] FIG. 3 illustrates an embodiment of contents navigation information in accordance with the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0016] In order that the invention may be fully understood, preferred embodiments thereof will now be described with reference to the accompanying drawings. [0017] FIG. 1 illustrates an interactive optical disk reproducing apparatus in which the present invention may be advantageously embodied. The reproducing apparatus 100 comprises an optical pickup 11, an IDVD system 12, a microcomputer 13, a buffer memory 14, and an Internet interface 15 through which the apparatus 100 is connected to a contents providing server 300. [0018] The IDVD system 12 includes a DVD engine for reproducing A/V data recorded on an I-DVD 10 and an enhanced navigation (ENAV) engine for reproducing contents data provided by the contents providing server 300 or contents data recorded on the I-DVD 10. [0019] The IDVD system 12 outputs the contents data in synchronization with the A/V data from the IDVD 10. As shown in FIG. 1, the reproducing apparatus 100 is connected to the contents providing server 300 through the Internet interface 15 by the mutual operations of the microcomputer 13 and the ENAV engine included in the IDVD system 12. [0020] ENAV contents data, which is additional contents data associated with the A/V data being reproduced from the I-DVD 10, is downloaded from the contents providing server 300 and then temporarily stored in the buffer memory 14. The buffer memory 14 can be logically divided into a first buffer (buffer 1) and a second buffer (buffer 2).
