Description

APAPATUS FOR INTERFACEING BETWEEN WEBBROWSER AND DSM-CC}

The present invention relates to an interlocking device for interworking a web browser and a digital storage media command and control (DSM-CC) so that a multimedia service can be provided using a web browser, in particular, a socket. The present invention relates to an interlocking device for linking a web browser and a DSM-CC by the method.

In general, the Internet is a computer network that exchanges data in accordance with a communication protocol called Transmission Control Protocol / Internet Protocol (TCP / IP). In general, services using the Internet require that one computer request information from another computer. It has a client / server structure that provides information, for example information written in HTML documents. The information providing side is called a server computer, and the information receiving side is called a client computer. The WWW (World Wide Web) is an Internet service of a client / server structure using a communication protocol called HTTP (Hyper Text Transfer Protocol). . Although the use rate of such internet service is exploding, it is pointed out that the network transmission quality is not guaranteed.

On the other hand, in the case of an interactive multimedia service, a large amount of data needs to be guaranteed to be transmitted stably while the service is provided on a network. Because of this characteristic, when the DAVIC (Digital Audio Visual Council) was created, the Internet, which is not guaranteed for network transmission quality, is not suitable for interactive multimedia services. (Asynchronious Transmission Mode) was selected. For this reason, DAVIC is currently providing mode services on ATM networks, not on the Internet.

1 illustrates a multimedia service system that performs a service according to the DAVIC standard. In FIG. 1, the multimedia service system includes a client terminal device 110, an ATM network 120, and a server 130. In addition, the client terminal device 110 may include an external input unit 112, an MHEG engine 114, a digital storage media command and control (DSM-CC) user-user (UU) unit 116, and a DSM-CC UN (User-). Network) 118 is configured.

In FIG. 1, the DSM-CC UN unit 118 attempts to connect to a server 130 providing a service by a client, and provides a server 130 capable of providing a service and an ATM network to receive a service from the server 130. The module receives a resource and opens a communication channel between the client terminal 110 and the server 130.

The DSM-CC UU unit 116 receives signals from the user through a communication channel secured by the DSM-CC UN unit 118, for example, "PLAY" and "PAUSE" of a movie to be watched. , "STOP", "FAST PLAY", "REWIND" and the like to receive the signal provided to the server 130, and serves to receive the results.

The MHEG engine 114 provides the user with an interface related to the service, issues an appropriate DSM-CC UU command for the user's input, and then displays the result back to the user. That is, it shows the user what services are available, for example, through the external input unit 112 such as a remote control, a keyboard, or a mouse, the user selects a specific service and manipulates a service associated with it, and the user returns the result. To show the action.

In the multimedia service system configured as described above, when the user operates the MHEG engine 114, the MHEG engine 114 sends a start signal to the DSM-CC UU unit 116. When the DSM-CC UU unit 116 receives the start signal from the MHEG engine 114, it sends a start signal to the DSM-CCUN unit 118 again so that the DSM-CC UN unit 118 receives network resources from the ATM network 120. Is assigned, and opens a communication channel between the client terminal device 110 and the server 130.

If an error occurs in this process, an appropriate error handling operation is performed, and when the process is successfully completed, the MHEG object for the MHEG engine 114 from the server 130 to work on the ATM network 120 After downloading, it is interpreted and the user is presented with introduction information about the service.

Once the user can select a service or perform operations such as operation through the MHEG engine 114, the MHEG engine 114 issues a command corresponding to the user's input to the DSM-CC UU unit 116, and the DSM The CC UU unit 116 transfers the information to the server 130 through the ATM network 120. When the server 130 transmits a predetermined MHEG document to the DSM-CC UU unit 116 via the ATM network 120 in response to a command corresponding to the user's input, the DSM-CC UU unit 116 transmits the MHEG document. To the MHEG engine 114, which provides it to the user.

As such, since the multimedia service system transmits information using an ATM network, network transmission quality is guaranteed compared to the Internet. However, with the explosive increase in the number of Internet users and the technical use of the Internet over ATM networks, the network's transmission quality can be guaranteed over the Internet. Accordingly, DAVIC has decided to include the Internet in the standard and is receiving technical proposals. As a result of this trend, there is a need to receive services according to the DAVIC standard on the Internet.

Accordingly, an object of the present invention is to provide an interworking device for interworking a web browser and a DSM-CC by a socket method.

In order to achieve the above object, the present invention provides a DSM-CC command for requesting a MHEG document to receive a service to an MHEG server through an ATM network, and a DSM-CC receiving a DSM-CC response signal transmitted from an MHEG server. And, a companion device for interworking a web browser, which is an internet search system, comprising: decoding and outputting a request signal in a string format generated by the web browser, and decoding a DSM-CC response signal transmitted from the MHEG server. A decoder for converting and outputting a response signal in a string format; An interface processor for transmitting a request signal in a string format generated by the web browser to the decoder through a predetermined socket, and transmitting a response signal in string form provided by the decoder to the web browser through the socket; When the string-type request signal generated by the web browser is decoded by the decoder, a DSM-CC command corresponding to the request signal is generated and provided to the DSM-CC, and a DSM-CC response provided from the DSM-CC is generated. And a DSM-CC pager that provides a signal to the decoder.
