The present invention 20 can recognize the interface of the terminal device to recognize the connection of the terminal, and can provide a multimedia communication service through a non-communication multimedia terminal device by providing a multimedia service that can be supported in the connected terminal device.

When the terminal device 102 or 103 is connected to the communication medium apparatus 101 through the terminal interface unit 21, the external interface method determination unit 22 refers to the interface method DB, and the external interface method of the connected terminal device is referred to. To judge. In this case, the external interface method may be exemplified above. For the brief description of each interface method, the IEEE1394 interface is a high-speed interface that connects a digital camcorder to an external device. Used. The USB interface is a high-speed interface that connects a digital camera to the outside and is mainly used as a storage device and used to transmit and receive stored data.

Audio In is a voice input interface that corresponds to a voice output terminal and is mainly connected to a terminal of a microphone type, and Audio Out is a voice output interface to a terminal of a speaker type. Video In is connected to a device having a camera that can input video through the video input interface, and Video Out interface is connected to a display device that can provide a video screen through the video output interface. In general, camcorders have IEEE1394 and AV in / out interfaces, and digital cameras have USB and A / V out interfaces.

The multimedia communication intermediate apparatus 101 or 20 performs a multimedia providing service through data transmission and reception with the terminal device 102 or 103 connected through the terminal interface unit 21. The multimedia services that can be provided through the intermediate apparatuses 101 and 20 are a real-time video (broadcast) data transmission service, a VoIP service, a web search service, a VOD service, a download and store (DnS) service, and a network storage access (NSA) service. These services are typically provided by a unique interface (the external interface described above) supporting each service.

Real-time video (broadcast) data transmission service is a service for transmitting the voice / image input from the camcorder 103 to the server or the terminal 105 via the Internet, the high-speed / high definition image and audio input from the camcorder 103 Real-time encoding and streaming transmission function and protocol for this are performed to deliver the data in real time through the Internet.

The VoIP service performs protocol for voice telephony service over the Internet, and performs encoding / decoding and transmission / reception of voice data. WEB service performs the necessary protocol and control functions to enable the Internet search service through the screen of the terminal. The VOD service performs a protocol for streaming and receiving video / audio data, decoding of video / audio data, and a player function and protocol for receiving and viewing a video selected through a web screen.

The DnS service performs a communication protocol and data transmission / reception function for downloading data through the Internet and storing it in a storage device of a connected terminal. The NSA service performs a function of uploading the contents of the storage device of the terminal to a storage device connected through the Internet as a function opposite to the DnS service.

The service list presenting unit 23 presents a list of services that can be supported by the interface method of the terminal device determined as a part of presenting a list of multimedia services that can be serviced by the interface method of the terminal device determined by the interface method determination unit 22. The selected service driver 24 recognizes the service selected by the user from the service list presented by the service list presenter 23 and drives the selected service. The selected service driver 24 reads the selected service from the service list DB. Let's do it. The driven service is provided to the server 105 through the network interface unit 25 or is provided from the server 105.

3 is a flow chart of a preferred embodiment of the present invention.

Step S31 is a step of determining whether the terminal device is connected to the communication network by grasping the external interface method of the non-communication multimedia terminal device, specifically checking each terminal interface in turn to check the connection state of the interface.

First, the connection state of the IEEE 1394 interface is checked (S311) and if activated, the real-time video (broadcast) data transmission service is added to the list of possible services (S312). In the next step, the connection status of the USB interface is checked (S313). If the USB interface is activated, the NSA and the DnS service are added to the list of available services (S314). The next step is to enter the A / V interface connection check step (S315).

If Audio Out is enabled and Audio in is enabled, add VoIP service to the service list. If Video Out is enabled while Audio Out is enabled, add WEB and VOD services to the list of available services.

When the external interface method of the terminal device is determined by the step S31, a service list that can be provided through the external interface is output (S32). When the user selects a service from the output service list, the selected service is driven (S33) It will provide a multimedia service.

The present invention recognizes a terminal device such as a camcorder connected through an IEEE1394 interface, real-time broadcast data transmission service, NSA service for backing up data from a storage device such as a digital camera connected via a USB interface, an MP3 player or other media connected via a USB interface. Mediation to enable DnS service to download new data from the Internet to storage devices such as players, VoIP service with microphone and speaker connected, WEB service and VOD service through camcorder or TV screen connected to Audio Out / Video Out interface You can do it.

The present invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, which are also implemented in the form of a carrier wave (for example, transmission over the Internet). It also includes. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention.

Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the equivalent scope will be construed as being included in the present invention.

The present invention provides a multimedia service that can automatically recognize a terminal device and provide the terminal device to a user through a characteristic of an external interface of a non-communication multimedia terminal device in which an internet communication is impossible in providing a selective multimedia service according to terminal recognition.

Since the list of services that can be serviced through the communication median device is dynamically displayed according to the state, the user can easily use the service without having to remember the list of available services according to the type of terminal or interface. By providing other services possible through different interfaces of one terminal device, it is possible to support various additional services through internet connection in addition to the basic functions of the terminal device.

In addition, by providing multimedia communication services through the interface of non-communication multimedia terminal devices, such as camcorders and digital cameras, users can reduce the purchase cost of separate expensive complex terminals and various multimedia of next generation Internet. The service may be performed through a non-communication terminal having a multimedia terminal characteristic.
