TECHNICAL FIELD [0001] The present invention relates to a reproducing apparatus, a reproducing method, a program, a program storage medium, a data delivery system, a data structure, and a manufacturing method of a recording medium. More specifically, the present invention relates to a reproducing apparatus, a reproducing method, a program, a program storage medium, a data delivery system, a data structure, and a manufacturing method of a recording medium for appropriately downloading an update file of a content already recorded on a recording medium. BACKGROUND ART [0002] DVD (digital versatile disk) video format is one of playback only standards of digital versatile disks (DVDs). In the DVD video format, content data such as video and audio is multiplexed with data of a variety of sub-pictures including caption, and is recorded in a program stream on a disk. Navigation data is also recorded on the disk to reproduce interactively the stream. [0003] In interactive reproduction, data is reproduced at a desired position or in a desired order. In the interactive reproduction, users can use a variety of functions of DVD. The available functions include a multi-angle function in which videos captured at various angles are reproduced, a multi-language function in which data is reproduced in a desired language selected from a plurality of languages, a parental control function in which a particular scene, such as a scene of violence, is prevented from being reproduced. [0004] A program stream can be produced by multiplexing a plurality of audio streams and a plurality of caption data streams. If data of different languages is thus recorded for one video content, such as a movie, on a single disk, a user can select voice and caption of a desirable language at the beginning of or during video reproduction. [0005] Patent Document 1 discloses a system that allows a user to easily download a content as a video work, including sound effects, moving image, and still image. Patent Document 2 discloses a technique that allows a portion of entire music data to be replaced with another data. [0006] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2003-140662 [0007] [Patent Document 2] Japanese Unexamined Patent Application Publication No. 2002-311967 DISCLOSURE OF INVENTION Problems to be Solved by the Invention [0008] The user can naturally reproduce only contents recorded on a disk loaded on a player. [0009] For example, if a disk having a movie content with English caption only is purchased, the user can display the English caption pre-recorded on the disk. To view the same movie content with another desired language different from the pre-recorded language, the user needs to purchase a different disk with caption information of the other desired language. [0010] To sell disks of a movie content in countries of different languages, a seller of the disks need to prepare disks with different caption information, or a plurality of types of disks, such as disks of English language, disks of Japanese language, and the like. [0011] For example, when a bonus track is added, or when caption and voice are partially modified, instead of the modification of an entire content, a disk with the bonus track added thereon, and a disk with the caption and voice partially modified must be newly prepared for re-distribution. [0012] Preparing such disks takes time, possibly resulting in the loss of large business chance. [0013] The present invention has been developed in view of the above-described problem and it is an object of the present invention to allow an update file of a content recorded on a disk to be downloaded, or to be distributed in a removable recording medium to easily handle a content file recorded on the disk and the update file. MEANS FOR SOLVING THE PROBLEMS [0014] In accordance with a first aspect of the present invention, a reproducing apparatus for acquiring a first data group and a second data group, and reproducing an AV stream using the acquired first and second data groups, includes detecting means for detecting a file system of the first data group, and virtual file system generating means for generating a virtual file system containing at least a portion of each of the first data group and the second data group, based on the file system of the first data group detected by the detecting means, and attribute information containing first information indicating a recording position of the second data group and second information indicating a path in the virtual file system of the second data group. [0015] A directory structure of the virtual file system may include at least a portion of a directory structure in the file system of the first data group detected by the detecting means. [0016] The virtual file system may include a directory containing a play list file managing reproduction of the AV stream, a directory containing a clip information file managing the AV stream, and a directory storing the AV steam. [0017] The second data group may be stored on one of a semiconductor memory and a magnetic disk, and the first information may indicate a path in a file system in the one of the semiconductor memory and the magnetic disk. [0018] The reproducing apparatus may further include reproduction control means for controlling reproduction of the AV stream by controlling reading of the first data group and the second data group based on the virtual file system generated by the virtual file system generating means. [0019] The reproducing apparatus may further include storage means for storing the acquired second data group, and management means for managing the file system of the second data group in the storage means, wherein the reproduction control means controls the reproduction by reading the second data group stored on the storage means based on the first information and the second information contained in the attribute information, the virtual file system, and the file system of the second data group managed by the management means.
