It is composed of one or more clients 200 connected to the sensory media generating device 100 through a communication network.

Each of the plurality of photographing apparatuses 110 is provided with different unique identifiers (GUIDs), and photographs images of different viewpoints and provides them to the sensory media generation server 130. The photographing apparatus 110 may be a camera for capturing an HD image.

The photographing apparatus 110 and the sensory media generation server 130 are connected through an IEEE 1394 network.

The sensory media generation server 130 assigns the same multicast address and different port numbers to each of the images photographed by the plurality of photographing apparatuses 110, and the SDP including the allocated multicast address and port number. A session description protocol message is generated and transmitted to the plurality of clients 200. At this time, the sensory media generation server 130 allocates the same multicast address and different port numbers to the plurality of images and the images received from the plurality of photographing apparatuses by executing one VP producer.

In addition, the sensory media generation server 130 receives the SDP message via a service access point (SAP) packet and receives a multicast address different from the allocated multicast address to the client 200 through a communication network. Here, the SDP message includes service attribute information including at least one of the allocated multicast address and a plurality of port numbers, a producer's name, an e-mail address, a video codec, a video quality, and a service type.

The client 200 analyzes the SDP message from the sensory media generating apparatus 100 to extract service attribute information, and outputs an image by a photographing apparatus selected by a user or a multi-view image by a plurality of photographing apparatuses. .

In addition, the client 200 may display a multi-view image by the plurality of photographing apparatuses 110 as a wide image using a network tiled display device.

The client 200 performing the above role refers to a terminal such as a PC.

According to another embodiment of the present invention, it may have a configuration further comprising a Venue server (not shown) for generating and providing a multicast address at the request of the sensory media generation server 130.

That is, the Venue server interconnects the sensory media generation server 130 and the plurality of clients 200 and exchanges video service information to provide a virtual space for collaboration, and the sensory media generation server 130 Assign multicast addresses as requested.

According to another embodiment of the present invention, when the user selects the VP producer, the sensory media generation server 130 displays a screen for selecting a channel value for each image from the plurality of photographing apparatuses 110. The user selects a channel value for each image from the photographing apparatus 110 through the channel value selection screen.

For example, when three HD images are received by three photographing apparatuses, a user allocates three channel values to each HD image as '63, 64, 65 '.

Then, when the user selects the HD video of the desired channel and executes the service, the sensory media generation server 130 allocates two multicast addresses.

By the above-described sensory media sharing system, when a video is transmitted to the multicast address through the sensory media generating apparatus 100, a plurality of clients 200 may be connected to receive a VP service using one consumer. have.

That is, the client executing the VP consumer service may receive the VP service using the SAP packet from the sensory media generating apparatus 100.

Referring to FIG. 2, the sensory media generation server 130 may include a communication unit 132, a VP (Video Presence) producer execution unit 134, a multicast address allocation unit 136, and a port number for communication with a plurality of clients. The allocator 138 includes an SDP message generator 140, an image receiver 142, and an image transmitter 144.

When the VP producer execution command is input by the user, the VP producer executing unit 134 executes the VP producer. In this case, the VP producer execution unit 134 may execute a VP producer by using an embedded program or by accessing a Venue server.

The multicast address allocator 136 allocates first and second multicast addresses when the VP producer is executed by the VP producer execution unit 134. That is, the multicast address allocator 136 may be configured to allocate a first multicast address that is equally allocated to each image photographed by a plurality of photographing apparatuses and a second SDP message generated by the SDP message generator. Allocates a multicast address.

In addition, the multicast address allocator 136 may request a multicast address allocation from a Venue server to receive a multicast address from the Venue server.

The port number assigning unit 138 allocates different port numbers to respective images photographed by the plurality of photographing apparatuses. In this case, the port number assignment unit 138 checks the position of each photographing apparatus by using the unique identification information of each photographing apparatus, and then includes the location information in the assigned port number.

In addition, the port number assigning unit 138 may receive a channel value from a user with respect to each image photographed by a plurality of photographing apparatuses and assign the channel value as a port number. That is, the user selects a VP producer and selects a channel value for each image from the photographing apparatus through the displayed channel value selection screen.

For example, when three HD images are received by three photographing apparatuses, a user allocates three channel values to each HD image as '63, 64, 65 '. Then, the port number allocator 138 may allocate the selected channel value as a port number.

The SDP message generator 140 generates an SDP message including a first multicast address allocated by the multicast address allocator 136 and a port number allocated by the port number allocator 138. 2 Send to multiple clients via multicast address. At this time, the SDP message generator 140 transmits the SDP message to the second multicast address through an SAP packet.

The image receiving unit 142 receives images from a plurality of photographing apparatuses via an IEEE 1394 network, and captures them using a Dvgrab Module.

That is, the image receiving unit 142 receives an HD class image from a plurality of photographing apparatuses to obtain an immersive and realistic high quality image.

The image transmitter 144 transmits an image according to a client's request among the images received by the image receiver 142. That is, the video transmitter 144 transmits HD video to MPEG2-TS (Transport Stream) using a VLC (Video LAN Client).

For example, when three images are transmitted by three imaging apparatuses, the image transmitter 144 transmits HD images (high definition images) to the second multicast address through three VLCs.

3 is a block diagram schematically illustrating a configuration of a client according to the present invention.

Referring to FIG. 3, the client 200 includes a communication unit 202 for communicating with a sensory media generating device, a VP consumer service execution unit 204 for executing a VP consumer service according to a user's request, and an SDP message. The generation unit 206 and the display unit 208 are included.

The SDP message generator 206 extracts service attribute information by analyzing the SDP message transmitted from the sensory media generating device by executing the VP consumer service.

That is, the SDP message analyzer 206 extracts an SDP message from the SAP packet from the sensory media generating device, and analyzes the extracted SDP message to extract service attribute information including a multicast address, a port number, and the like. do.

The display unit 208 outputs service attribute information extracted by the SDP message analyzer 206 and outputs an image selected by the user.

That is, the display unit 208 displays the service attribute information extracted by the SDP message analyzer 206 so that the user can check it.

The display unit 208 may be a network tiled display device for displaying a multi-view image by a plurality of photographing apparatuses as a wide image or a local display device for outputting an image selected by a user.

Accordingly, the display unit 208 reproduces using a local display through VLC, and sends a wide video to a networked tiled display using a scalable video consumer (SVC).

Here, the tiled display refers to projecting unit images provided from a plurality of photographing apparatuses onto a single screen, and then attaching a plurality of unit images projected onto the screen to form a single high resolution super large image.

This tiled display technology can create ultra-large images at low cost, beyond the limitations of liquid crystal display (LCD) and plasma display pannel (PDP) technology, which are currently limited in large-scale, and furthermore, the concept of monitor for simple information delivery to users It is used as a means to provide virtual reality beyond.

The client 200 configured as described above may receive a VP service using one consumer when an image is transmitted to the multicast address through the sensory media generating apparatus.

4 is a diagram illustrating a sensory media sharing method according to the present invention.

Referring to FIG. 4, the sensory media generating apparatus allocates the same multicast address and different port numbers to respective images photographed by the plurality of photographing apparatuses when the VP producer is executed (S400).

In other words, the sensory media generating apparatus automatically assigns the same multicast address and different port numbers to each image captured by the plurality of photographing apparatuses when the VP producer is executed.

In addition, when the VP producer is selected by the user, the sensory media generating apparatus displays a channel value selection screen for selecting a channel value for each image from a plurality of photographing apparatuses. Then, after receiving a channel value for each image from each photographing apparatus through the channel value selection screen, and executing the selected VP producer, the sensory media generating device is the same for each image from a plurality of photographing apparatuses. The multicast address may be allocated and the received channel value may be assigned as the port number.

Then, the sensory media generating device generates an SDP message including the allocated multicast address and a port number (S402) and transmits the generated SDP message to a plurality of clients (S404). That is, the sensory media generating apparatus receives the SDP message through a SAP packet and receives a multicast address different from the allocated multicast address and transmits the SDP message to the client through a communication network.

Then, the client analyzes the SDP message to extract and display service attribute information (S406). That is, when the client receives the SAP packet transmitted from the sensory media generating device, the client extracts an SDP message in the SAP packet. The client then analyzes the information in the extracted SDP message, extracts service attribute information including the multicast address and port number transmitted through the VLC, and displays the service attribute information in the GUI status window.

When the user selects the displayed service property information, the client displays a camera selection screen on which the location information of the camera is displayed (S408).

When the user selects a camera of a desired position on the camera selection screen (S410), the client transmits camera selection information to the sensory media generating device (S412).

Then, the sensory media generating device transmits the image photographed by the selected camera to the client (S414).

The client may obtain a wide image by playing the image from the sensory media generating device using a local display through VLC and sending the image to a networked tiled display using a scalable video consumer (SVC).

5 is a flowchart illustrating a method in which a sensory media generating device according to the present invention supports sharing of sensory media.

Referring to FIG. 5, when the VP producer is executed (S500), the sensory media generating apparatus allocates a port number for each image photographed by each camera by using GUID information of each camera (S502).

That is, the sensory media generating device executes the VP producer by using the built-in program or by connecting to the Venue server.

When the VP producer starts, the sensory media generating apparatus checks the position of each camera by using GUID information of each camera and then includes the checked position information in the port number. That is, each camera has different global unique identifier (GUID) information. Therefore, the sensory media generating apparatus can check the location information of the image coming through each camera using the GUID information.

After performing S502, the sensory media generating apparatus allocates a first multicast address for an image captured by each camera and a second multicast address for SDP message transmission (S504).

According to another embodiment of the present invention, the sensory media generating apparatus does not directly allocate the first and second multicast addresses, but requests a multicast address assignment from a Venue server to allocate a multicast address by the Venue server. I can receive it.

When the S504 is performed, the sensory media generating device generates an SDP message including service attribute information such as the first multicast address and the port number (S506), and generates the SDP message through the SAP packet. The second multicast address is used to transmit to the plurality of clients (S508).

Subsequently, when the sensory media generating device is requested to stop execution of the VP producer (S510), it stops transmitting the SAP packet and releases the multicast address (S512).

Then, the sensory media generating device stops the VP producer service (S514). In other words, when the sensory media generating device disables the VP Producer service, the Stop () function is executed and the running thread is stopped, and the SAP packet is no longer transmitted.

6 is a flowchart illustrating a method for sharing sensory media by a client according to the present invention. 9 is an exemplary diagram of a tiled display screen according to the present invention.

Referring to FIG. 6, when the VP consumer service is executed (S600), the client receives an SAP packet from the sensory media generating device (S602).

The client extracts an SDP message from the SAP packet (S604), analyzes the extracted SDP message, and extracts and displays service attribute information (S606).

That is, the client analyzes the information in the extracted SDP message, extracts service attribute information including the multicast address and port number transmitted through the VLC, and displays the service attribute information in the GUI status window as shown in FIG.

Referring to FIG. 7, service attribute information including a multicast address and a port number is displayed on the SDP message contents confirmation screen.

When the user clicks the desired information on the SDP message contents confirmation screen (S608), the client displays the camera selection screen as shown in FIG. 8 (S610).

Location information of each camera is displayed on the camera selection screen, so that the user selects a camera of a desired position through the camera selection screen.

When a camera is selected through the camera selection screen (S612), the client displays an image captured by the selected camera (S614). In this case, the SDP message contents confirmation window, the image providing window by the camera selected by the user, and the camera selection window may be displayed on the screen of the client.

When the user wants a tiled display while displaying an image using his client (S616), the client displays the multi-view image transmitted from the sensory media production apparatus as a wide image as shown in FIG. 9 ( S618). That is, when the user wants the tiled display, the client generates and displays the multi-view image as a wide image according to the setting value of the tiled display device.

According to the above method, the video is selected and processed according to the display status of the client, the bandwidth of the network, and the performance of the machine.The same video sharing function is provided at a long distance through the multicast address, By using a plurality of images provided through the wide image is provided.
