Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a DVD (Digital Video Disc) player, and more particularly to a Web DVD player that can connect existing conventional DVD discs to related websites. machine. [Prior Art]

WebDVD, also known as Internet DVD, Internet-connected DVD, and ENav: enhanced navigation, is a powerful concept for improving DVD-Video technology through Internet technology. WebDVD combines the best of DVD and Internet, so that it complements each other perfectly and is used in many areas. For example, a WebDVD movie can be connected to the Internet for product marketing, audience discussions, and multi-participant games. A product video can use webpage technology to create gorgeous product images to entice viewers to buy directly on the spot. Similar applications are endless. The WebDVD title takes full advantage of the timely and automatic updates of the software on the Internet to supplement the latest information, update the links to relevant websites, current news and events, and special advice on services and products. Therefore, even if the WebDVD disc has been removed from its maker, it can be further improved or renewed. In addition, this approach makes the previously fixed media become dynamic and updatable, extending its useful life. The DVD Forum is an industry consortium (http://www.dvdforum.org) > It is currently developing standards for the content of web programming connected to WebDVD video discs. This standard allows for the addition of an embedded network connection to a DVD video disc that connects the disc

〇 \89\89225 D0C 1352911 Connect to their website containing specific disc content. The above website may also include a new navigation menu that is convenient for the player to download, so that the player can use the menu instead of the original DVD menu. However, in the case of existing conventional DVD video discs, there is no enhanced content that can be connected to the website and used, but WebDVD video discs can do the same. This situation will inevitably hinder and actually prevent the enormous potential of engaging in e-commerce activities as the user plays a large number of traditional discs that he owns. Therefore, there is an urgent need to provide a WebDVD player that can find a website associated with the content of existing conventional DVD discs. SUMMARY OF THE INVENTION The present invention provides a WebDVD player capable of connecting a conventional DVD disc to a related website, and the player can also be used to play a normal WebDVD disc. According to a first embodiment of the invention, the player comprises a small repository containing a URL (Uniform Resource Locator) directory of a popular DVD content provider. When the disc is loaded into the player, the player reads the provider's unique identifier (PVR_ID: provider unique identification) from the disc and uses the PVR_ID to find the URL of the relevant content provider from the URL directory. The content provider's URL is then used as a table index that includes the title identifier (Title_IDs: title identifications) of certain popular program content created by the content provider on the disc, the location of the Title_ID on the disc, Get the method of Title_ID and the URL of the relevant website. With this, the player tries to follow the table

〇\S9\89::5 DOC 1352911 The specified method obtains the Title-ID of the disc, and compares the obtained Title"D with the data in the Title-ID column of the table to find the content provider for finding the content. The corresponding URL of the specific web page. According to the second embodiment of the present invention, a database having a function similar to that of the first embodiment is installed on a web server. The database has a more comprehensive use — the URL directory that connects to the content provider's website and the video-like title directory that can be read by the player. In this embodiment, after the disc is loaded into the player, the player can read the PVR-ID and the Title-ID from the disc, and then connect the disc to the resource website to search for the content corresponding to the player. The above database is provided by the player manufacturer or other organization (eg, DVD Forum). The second embodiment of the present invention is a combination of the first and second embodiments. When the disc is loaded into the player, the player first consults its internal database to find the corresponding Title_ID. If it is not found, the player will access the resource website to find the corresponding Title_ID. Other objects and advantages of the present invention will be apparent from the description and appended claims. [Embodiment] FIG. 1 is a schematic diagram showing the connection between a WebDVD player and an Internet and a network according to an embodiment of the present invention. As shown in the figure, the DVD video disc 2 is loaded into the WebDVD player to interact with the related website set in the web server 25. The player can be built in a variety of ways, such as a personal computer (PC). The disc 20 can be a WebDVD video disc or an existing conventional DVD video disc. For the traditional DVD video disc

0 \3_225 DOC 1352911 Connected to the relevant website, the player uses the only PVR_ID (S donor unique identifier) in the disc that can determine the disc content provider and the only Title _id that can determine the unique title of the disc (eg movie) . For example, all traditional DVD video discs can be provided with pvR-ID. As shown in Table 1, the PVR_ID is found in VMGI_MAT (Video Manager Information Management Table). The corresponding byte location in the data structure: Sub-data structure Byte group content 〇 to 11 VMG_ID (Video Manager ^^ 12 64 to 95

When the number of bytes of the PVR_ID is less than 32, the vacancy used by the deficit is expressed as 〇〇. However, ▲ and: in the Jing video standard, there is no provision for the acceptance of - (1), the method of obtaining the mu by the right-hand method is to use the haircut nicking area (bca:b_) in some traditional discs. Unique serial number. In addition, the disc ~ (universal disc format.

Universal Disc Format) is fortunate to have a ... η, 会~,. The volume set identifier (乂〇丨隐 以' is called Tltle-ID. Another way is to use

〇A8y\S9225 OOC -9- 1352911 The unique Title-ID stored by the donor in the sector of the disc data. This data sector contains special data. There are a number of content providers in the disc's data structure for storing their personal information, including the only TiUe(1). For example, the boot area for storing content provider information is used for this purpose. The third way is to use the generated Title_ID. This method can be used to generate a statistically unique TiUe_ID based on certain information on the disc. For example, VMGI-MAT can be used to generate the TiUe_ID of the disc. The above method will be explained in detail below. The use of this method guarantees that the title identifier can be obtained for all conventional discs. In a first embodiment of the invention, the player 丨〇 includes a small repository containing a uRL directory of content providers of currently popular DVDs, such as AOL, Time Warner, Walt Disney, and the like. When the disc 20 is loaded into the player 10, the player 1 will read pvR_iD from the disc and use It PVR_ID to find the URL of the corresponding content provider from the URL directory. The content provider's URL is then used as a table index. As shown in Table 2, the table includes the title identifier (Title_IDs) of some popular program content created by the content provider, the location of the Title_ID on the disc, the method of obtaining the Title_ID, and the URL corresponding to the related website. Thereby, the player 10 tries to obtain the Title_ID of the disc according to the location data column and the acquisition method column of the table 2, and then compares the obtained Title_ID with the data in the column of the table TiUe_m to find out for searching. The corresponding URL of the content provider's specific web page. 〇\89\89225 DOC -10- 1352911 Table 2: Specification of the player's small and medium-sized database. TitleJDs — Ji Location acquisition method Algorithm type URL of the relevant website οποίοι... BCA Read N/A — 一•— · · 1011100... VMGI MAT generates ID type 2 - vv vv w.uibiicy.com In Form 2, the position of TiUe_ID can be located in BCa, that is, in the data sector of the original poor material, or in VMGI - MAT or other positions in the disc π · σ structure. The acquisition method intercepts in detail the method of obtaining the 丨e-ID t method, for example, which can be directly read from a specific position of the disc.

Title-IDs, or generated by a specific algorithm listed in the algorithm type block

Title—ID. The list of algorithms corresponding to each of the algorithm types in Table 2 needs to be installed in the player in advance, so that the player can calculate and generate the Title-ID by using the indicated algorithm and related data. The URL in the relevant website column indicates the URL corresponding to T "le-ID. For example, if κ is specified in the location ,, and "read" is specified in the acquisition method, then (4) machine H) will try to disc from the disc. Read the BCA information to find out its Title_ID. However, not all faces have BCA', and not all DVDs can read bca. In this case, 'other method may be needed (for example, "Generate 1〇, ,). If so, the player will use the secret location information (such as VMGI-MAT) and generate the Ding-(1) based on the specified algorithm. There are very few methods for generating Tuie-ID, which makes a method using a method similar to that used in CD-DB (CD 料 康 · · 浑 浑, 浑. CD Database), which method Η

0 \89\S9225 DOC 1352911 connects the CDs to the service website and then uses the start and end addresses of the title group or segment to calculate and generate the Title_ID. The other method uses the information located in the VMGI-MAT to generate the Title-IC). For example, all the group data of VMGI_MAT can be spliced into one, and the splicing data can also be decomposed into a specific number of stone horses for generating D(1)^ id. 2 is a schematic diagram of a detailed flow 30 for finding a related network for a particular disc in accordance with a first embodiment of the present invention. After the disc is loaded into the player (step 32), the player will determine whether the loaded disc is a WebDVD according to the system file of the disc (step 34, if the disc is WebDVD, the player will follow The WebDVD standard that has been officially adopted on the DVD Forum connects the disc to the relevant website (step 36) and starts WebDVD navigation (step W). On the other hand, if the disc is a conventional DVD, the player 1〇 The PVR-ID is read from the disc to determine the relevant content provider (step 4〇), and the URL directory located in the player database is searched to find the URL with the content provider. If there is no consistent coffee in the directory, the player will start the traditional D VD mode to start the traditional call. If the URL is found in the fox directory, the muscle will be ^ HL shooter in the form 2 (4) The first record in the table associated with the above URL is downloaded to the internal memory of the player: (step 48), and then according to the location block in the record, the acquisition method and the algorithm type column are managed to obtain from the disc t iUe_iD (Step 5〇).
