The present invention relates to a web hard disk server for downloading predetermined broadcast content from a broadcast content providing server and physically sharing the same broadcast content and using the same, among the broadcast content downloaded from the broadcast content providing server. Regarding the same broadcast content, only one broadcast content is stored and used in a wired / wireless terminal.

The network provides a variety of services that are very useful for users. Especially, the web-hard disk service provides a remote storage system, which is a storage space on your computer system (PC). It is a service that can be used like a disk drive. Users can upload or update any file or data remotely to the storage space in the web hard disk server, that is, the web hard disk in the web hard disk server, or download the file or data from any location. It can be used. As such, the service using the web hard disk server uses the web hard disk of the web hard disk server as a storage device mounted on a user's computer, and the web hard disk is divided into a private and a public file. Each folder is formed so as to be stored, and the shared folder is freely available to other users authenticated by the corresponding host user.

However, the conventional method used for private use has inefficiency of storing the same broadcast content in physical storage spaces of different users even when multiple users store and use the same broadcast content.

In addition, the existing method used for the public is to access the shared folder as well as the domain name (IP address) and ID so that other users can be connected to the website where the web hard disk server is operated. I had the inconvenience of telling me my password. If the unspecified number of people share specific broadcast contents without the login procedure, there is a problem such as a violation of copyright.

On the other hand, such as DMB broadcasting (Digital Multimedia Broadcasting), streaming broadcasting can be performed in real time to the terminal through a satellite network, network network, wireless network in real time, in addition to the real-time broadcasting, the web hard by the request of the terminal Broadcasting may be performed by storing broadcast content in a disk server. The broadcasting method using the web hard disk server has a structure in which the web hard disk server downloads it from a source providing a broadcast content (hereinafter, referred to as a broadcast content providing server), stores it, and transmits it to each terminal whenever necessary.

1 is a diagram illustrating a broadcasting state using the web hard disk server. Referring to FIG. 1, the web hard disk server 110 downloads and stores specific broadcast content from the broadcast content providing server 100 according to a request of each wired / wireless terminal 140 or 150 (eg, a PC, a mobile phone, or a DMB phone). After that, it has a structure for transmitting to each wired or wireless terminal (140,150). Accordingly, the web hard disk server 110 should download the broadcast content requested from the wired / wireless terminals 140 and 150 from the broadcast content providing server 100 and allocate the broadcast content requested by the unique ID of each wired / wireless terminal. However, when a plurality of wired and wireless terminals 140 and 150 are requesting the same broadcast content, when the same content is to be downloaded and stored in the web hard disk server 110, the inefficient capacity waste of the web hard disk server 110 is inefficient. A problem arises. That is, despite the same broadcast content, there is a problem in that the capacity of the web hard disk cannot be efficiently used because the same broadcast content must be repeatedly stored for each unique ID of each wired / wireless terminal.

The present invention has been made to solve the above problems, in the web hard disk server for downloading and storing broadcast content, if the same broadcast content is assigned by each unique ID of each terminal, but the method of physically sharing and storing it For the purpose of presentation.

In order to achieve the above object, the web hard disk server according to the present invention, when the broadcast content downloaded from the broadcast content providing server is the same broadcast content, does not store the same broadcast content separately, but stores only one broadcast content. And an index storage unit for assigning an index, which is a unique number of broadcast contents stored in the web hard disk, for each unique ID of a wired / wireless terminal requesting transmission of the corresponding broadcast contents.

The web hard disk server may further include an input unit for interfacing with an administrator of the web hard disk server, a list of stored broadcast contents of the web hard disk server, a web hard disk total capacity, a web hard disk used capacity, and a management menu. The display unit for displaying, and if there are a plurality of the web hard disk, router that serves as a connection gate of the plurality of web hard disk, and a network connection for providing a network connection protocol is characterized in that it further comprises.

In addition, the download method to the web hard disk server, the network content between the broadcast content providing server and the web hard disk to enter a download mode in which a specific broadcast content in the broadcast content providing server is downloaded, and the broadcast content Storing the broadcast content received from the provisioning server in a temporary buffer and comparing and comparing the same broadcast content with the broadcast content stored in the temporary buffer in the web hard disk; and, if there is the same broadcast content, in the temporary buffer. The process of assigning the index of the broadcast content existing on the web hard disk to the unique ID of the wired / wireless terminal that requested the broadcast content without performing the process of storing the broadcast content on the web hard disk, and does not have the same broadcast content In the case that the broadcast content in the temporary buffer Storing the web hard disk, assigning an index of the broadcast content stored in the web hard disk to a unique ID of the wired / wireless terminal requesting the corresponding broadcast content, and deleting the broadcast content in the temporary buffer. It is done.

Hereinafter, the detailed description of the preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the reference numerals to the components of the drawings it should be noted that the same reference numerals as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to general practices of those belonging to the technical field of the present invention, and the definitions should be made based on the contents throughout the present specification.

2 is a state diagram having a broadcast content providing server, a web hard disk server, a router, a network, and a wired / wireless terminal according to the present invention.

The broadcast content providing server 210 is a server having a plurality of broadcast contents, and performs a function of downloading specific broadcast contents to the web hard disk server 300 at the request of the wired / wireless terminals 240 and 250. The broadcast content refers to all data files such as movies, dramas, animations, music videos, etc., in particular, video (including photos and flash) and sound (including music and ringtones), text (E-mail, E-card, File) and its combined files.

The web hard disk server 300 is connected to the wired / wireless terminals 240 and 250 through the network 220 and the satellite / wireless network 230, so that the broadcast content requested by the wired / wireless terminals 240 and 250 can be broadcast content providing server ( It downloads from 210 and stores the web hard disk 370. The stored broadcast contents are transmitted to the wired / wireless terminals 240 and 250 through the network 220 and the satellite / wireless network 230 at the request of the wired / wireless terminals 240 and 250. Accordingly, the wired / wireless terminals 240 and 250 receive and reproduce broadcast content stored in the web hard disk 370.

There are a plurality of web hard disks 370 in the web hard disk server 300. The web hard disk 370 performs a memory function in which the broadcast content is substantially stored. The web hard disk 370 may be connected to a plurality of web hard disks through an internal bus, and may also be connected to web hard disks physically separated through a router 360. In FIG. 2, the web hard disk server 300 is illustrated as if the web hard disk 370 is located in the same server space. However, the web hard disks in the different web hard disk servers may be interconnected through the router 360. It will be obvious.

On the other hand, the biggest feature of the present invention, although the broadcast content stored in the web hard disk 370 takes the form of logically separately stored for each wired or wireless terminal, but has the concept of physically shared storage for the same broadcast content Is the point. That is, the broadcast content downloaded from the broadcast content providing server 210 has an appearance that is stored for each unique ID of the wired / wireless terminals 240 and 250, but is substantially out of the broadcast content downloaded from the broadcast content providing server 210. The same broadcast content is not separately stored for each unique ID, but is stored in the web hard disk only as one broadcast content, and only the index value of the same broadcast content stored is assigned for each unique ID of the wired / wireless terminal. The same broadcast content stored as described above has a feature of a personal web hard disk which is individually downloaded to the wired / wireless terminal at the request of wired / wireless terminals. The operation of the web hard disk will be described later in detail with reference to FIGS. 4, 5A, 5B, 6, and 7.

The wired and wireless terminals 240 and 250 perform a function of downloading and playing broadcast contents from the web hard disk server 300 through the network 220 or the satellite / wireless network 230. The wired and wireless terminals 240 and 250 download specific broadcast contents stored in the web hard disk server 300, respectively. For this purpose, the wired and wireless terminals 240 and 250 are assigned respective unique IDs (or unique IPs and unique serial numbers). Download your own broadcast content for each unique ID. The wired / wireless terminals 240 and 250 are terminals that can be connected to a wired / wireless communication network, such as a personal computer, a mobile phone, and a DMB phone.

Meanwhile, the web hard disk server 300 of FIG. 2 omits other functional blocks and only the web hard disk 370 and the router 360 so as to clearly show the features of the present invention. Detailed building blocks of the server 300 are shown and described.

3 is a block diagram illustrating an internal configuration of a web hard disk server 300 according to the present invention.

The display unit 340 manages the use status of the user who uses the web hard disk server 300 or displays the use status of the web hard disk, and the like. The administrator of the web hard disk server uses the display unit 340. Performs web hard disk server management by viewing various figures. Although the contents displayed on the display unit 340 are illustrated in FIG. 7, an embodiment of such a display unit will be described later with reference to FIG. 7.

The input unit 350 is a user interface composed of various numbers and function keys. The administrator of the web hard disk server 300 performs various functions of the web hard disk server through the input unit 350, and the web through the input unit. Control and manage your hard disk server.

The web hard disk 370 is a plurality of hard disks in which broadcast contents uploaded from wired and wireless terminals are stored. The web hard disk 370 has a plurality of web hard disks connected to each other through an internal bus. The physically separated web hard disks are interconnected through routers 360. In the present invention, the broadcast content stored in the web hard disk 370 takes the form of being logically separately stored for each user, but is physically shared and stored as described above.

The network connection unit 330 is a function unit that provides a connection protocol for the web hard disk server 300 to connect to a network, and it will be apparent that the connection protocol is not limited such as TCP / IP and TCP / UDP. .

The control unit 310 controls the respective function units to store the broadcast content downloaded from the broadcast content providing server on the web hard disk.

The index storage 320 performs a function of setting an index (eg, a unique number, an address address) of broadcast content stored in the web hard disk 370 for each user. For example, taking the table shown in the following [Table 1] as an example,

TABLE 1

Wired and wireless terminals Index of Broadcasting Contents Stored on Web Hard Disk First Wired and Wireless Terminal 1-2, 1-5, 1-7 2nd wired and wireless terminal 1-2, 1-3, 1-7, 1-9, 1-10 .... .... .... .... .... ....

As shown in [Table 1], the first wired / wireless terminal stores and uses broadcast contents having a unique number of indexes 1-2, 1-5, and 1-7 on the web hard disk, and the second wired / wireless terminal 1 Broadcast contents with indexes -2, 1-3, 1-7, 1-9 and 1-10 are stored and used on the web hard disk. By the way, although the broadcast content having the index is used through the web hard disk, respectively, as shown in [Table 1], in the case of the broadcast content having the indexes 1-2 and 1-7, the first wired / wireless terminal and the second wired / wireless It can be seen that the terminal is sharing and using. The above sharing means only physical sharing but not logical sharing. That is, although broadcast contents having the indexes 1-2 and 1-7 refer to physical sharing, which is broadcast contents stored on a specific web hard disk as the same broadcast contents, the first user and the second wired / wireless terminal may use the same. It has logical individual characteristics.

4 is a diagram illustrating a logical connection and a physical connection relationship between broadcast content stored in a web hard disk server and individual wired / wireless terminals as shown in [Table 1].

For convenience of description, as shown in FIG. 4, the music broadcasting content stored in the web hard disk includes 10 music broadcasting contents, ranging from 1-1 broadcasting contents to 1-10 broadcasting contents, and the movie broadcasting stored in the web hard disk. It is assumed that the content consists of a total of 10 movie broadcasting contents, ranging from 2-1 broadcasting contents to 2-10 broadcasting contents. Assuming that 10 music broadcasting contents and 10 movie broadcasting contents are stored in the web hard disk as described above, the first wired / wireless terminal 450 may have 1-2, 1-5, 1- of 20 broadcasting contents. 7 Download music broadcasting contents (452,454,456) and download 2-1, 2-4, 2-7, 2-8, 2-9, 2-10 movie broadcasting contents (458,460,462,464,466,468). (400) downloads 1-2, 1-3, 1-7, 1-9, 1-10 music broadcast contents (402,404,406,408,410) and 2-2, 2-3, 2-4, 2-5, 2- 7, 2-8, 2-10 movie broadcast content download (412, 414, 416, 418, 420, 422, 424) is received and used.

Accordingly, the first wired / wireless terminal 450 and the second wired / wireless terminal 400 share music broadcasting contents 1-2, 1-7, and 2-4, 2-7, 2-8, and 2-10 movie broadcasting contents. It can be seen that it is used. The sharing does not mean that the file is completely shared and downloaded, but only that the first wired / wireless terminal and the second wired / wireless terminal use a single broadcast content together without managing the broadcast content separately on the web hard disk. That is, when the broadcast content stored in the web hard disk by the first wired / wireless terminal 450 and the second wired / wireless terminal 400 is the same broadcast content, only the broadcast content that is downloaded once without being stored in the web hard disk is not duplicated. This means that the registered and stored broadcast contents are used as logical web hard disks that are matched to each user area as shown in [Table 1] and FIG. 4 so that each user can use them individually. The download method from the broadcast content providing server to the web hard disk server will be described later along with the flowchart of FIG. 7.

5A and 5B are diagrams illustrating screens of respective wired and wireless terminals.

An example of the screen of the first wired / wireless terminal when the first wired / wireless terminal is connected to the web hard disk is shown in FIG. 5A, and an example of the screen of the second wired / wireless terminal when the second wired / wireless terminal is connected to the web hard disk in FIG. 5B. Shown. On the screens of the first wired / wireless terminal and the second wired / wireless terminal, the usage amount (502,512) of the web hard disk used by each wired / wireless terminal) is displayed. The size of these broadcast contents (508, 518) and the available web hard disk capacities (504, 514) are displayed. Referring to the difference between FIG. 5A and FIG. 5B, it can be seen that only the type of stored broadcast content varies according to a user.

6 is a diagram illustrating an example of a screen displayed on a display unit of a web hard disk server.

The web hard disk basically takes a separate storage method, but has the structure of sharing the broadcast content physically because it takes the structure of storing the same broadcast content only once. For example, suppose that 10 pieces of music broadcasting content (10 Mbytes each) are stored in a total 100Mbyte web hard disk, and 10 pieces of movie broadcasting contents are stored in a web hard disk (10 Mbytes each). In this case, a total of 1,100 Mbytes (100 Mbytes + 1,000 Mbytes) of web hard disk capacity is used to store 20 broadcast contents.

However, when using the concept of sharing and storing the same broadcast content according to the present invention, the apparent total capacity displayed by each of the wired and wireless terminals to be used individually appears to be using a capacity larger than 1,100 Mbyte, which is a physical use capacity. can do..

For example, among the stored 10 music broadcasting contents and 10 movie broadcasting contents, the first wired / wireless terminal may select 3 music broadcasting contents (3 * 10Mbyte = 30Mbyte) and 6 movie broadcasting contents (6 * 100Mbyte = 600Mbyte). In case of receiving and using it, it looks like the web hard disk of total 630Mbyte (30Mbyte + 600Mbyte) capacity is used, and the second wired / wireless terminal has 5 music broadcasting contents (5 * 10Mbyte = 50Mbyte) and 7 pieces. In the case of receiving and using movie broadcasting contents (7 * 100Mbyte = 700Mbyte), it is apparent that a web hard disk with a total capacity of 750Mbyte (50Mbyte + 700Mbyte) is used.

Therefore, although the actual physical capacity of the web hard disk used by the first and second wired and wireless terminals is only 1,100 Mbytes (602), the two wired and wireless terminals have 630M byte and 750Mbyte capacities, respectively. Since it has an external appearance using a hard disk, a total of 1,380 Mbytes (630 M + 750 M) of capacity 604 is used.

7 is a flowchart illustrating a process of downloading broadcast content in a broadcast content providing server to a web hard disk server according to the present invention.

First, a process of connecting between the broadcast content providing server and the web hard disk server 300 (S702). The connection may be made at the request of the wired or wireless terminal, or the connection may be made by a web hard disk server administrator. If the connection is successfully established, the broadcast content download mode in which the specific broadcast content in the broadcast content providing server is downloaded to the web hard disk server is entered (S704). The download mode entry means that the web hard disk server enters the download mode when a request is made to the broadcast content providing server to download a specific broadcast content.

When the entry into the broadcast content download mode is successfully performed (S704), the broadcast content providing server transmits the specific broadcast content to be downloaded to the web hard disk server 300 (S706). The web hard disk server 300 stores the received broadcast content in a temporary buffer (S708). Thereafter, the web hard disk server searches for its own web hard disk and determines whether the same broadcast content as the broadcast content stored in the temporary buffer exists in the web hard disk (S710).

Determining whether the same broadcast content exists (S710) may be performed in various ways. The index (INDEX) in the head information of the first head of the broadcast content is analyzed to determine whether the indexes of the corresponding broadcast content are the same or broadcast. Compare and contrast the actual data frames of the content one by one, or instead of comparing and collating all the data of the broadcast content in order to reduce the comparison time, (eg, every 10 frames in the case of a video). As such, there is no limit to the method, such as being able to compare and contrast the contents of broadcast contents.

As a result of determining whether the same broadcast content exists, when the same broadcast content does not exist, the process includes storing the broadcast content in the temporary buffer as a web hard disk (S714). The index of the broadcast content stored in the web hard disk is registered in the index storage unit as user's use broadcast content information (S716), and the broadcast content in the temporary buffer is deleted (S718). On the other hand, if the same broadcast content exists, the index of the same broadcast content that has already been stored on the web hard disk is registered in the index storage unit as the used broadcast content information of the user (S712), There is a process of deleting broadcast content (S718).

Meanwhile, in steps S706 and S708, the web hard disk server 300 downloads the broadcast contents requested from the wired / wireless terminal 210 and stores them in a temporary buffer. If the same broadcast content exists in the web hard disk server by determining whether it exists in the web hard disk server has a process of index registration (S712) of the existing broadcast content instead of the broadcast content existing in the temporary buffer.

However, according to another embodiment of the present invention, before downloading the broadcast content requested from the wired / wireless terminal into the temporary buffer, it is determined in advance whether the same broadcast content as the broadcast content requested from the wired / wireless terminal exists in the web hard disk, and thus the same broadcast content is provided. If present, the broadcast content transmission step S706 and the temporary buffer storage step S708 may not be performed.

In addition, as another embodiment of the present invention, when a plurality of wired / wireless terminals have the same broadcast content requested for reservation download, only one broadcast content may be downloaded. For example, when the first wired / wireless terminal requests a reservation download of the first broadcast content broadcasted at 23:00, the controller stores the broadcast ID unique ID and the like and sets the reservation download. Subsequently, when the second wired / wireless terminal requests a reserved download for the first broadcast content broadcasted at 23:00, the web hard disk server searches for a list of broadcast content previously reserved and sets the same first broadcast content as a reservation. The first broadcast content is downloaded only once. Thereafter, the first and second wired and wireless terminal IDs of the first and second broadcast content reservation download requests are allocated and registered with the index of the first broadcast content.

In the above description of the present invention, a specific embodiment such as a web hard disk server has been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the patent scope of the present invention is not to be determined by the above-described embodiment, and it will be apparent that the claims are not limited to the claims as well as the equivalent scope.

As described above, the present invention uses the web hard disk individually for each user by physically sharing and storing the same broadcast content among a plurality of individual broadcast contents downloaded from the broadcast content providing server to the web hard disk. Therefore, the web hard disk capacity can be used efficiently.
