It may include a control unit (not shown) for controlling the.

The presenter terminal 110 is a terminal of a person presenting a presentation. The presenter terminal 110 may display the presentation content and share the presentation content by transmitting the presentation content to the client terminal 120 through a communication unit. The client terminal 120 may share the presentation content by rendering and displaying the presentation content displayed on the presenter terminal 110. In this case, one or two or more presenter terminals 110 and client terminals 120 may exist and may be connected through a session.

The presenter terminal 110 and the client terminal 120 may include an application that can use the presentation sharing service on the WEB.

The presenter terminal 110 and the client terminal 120 include a personal computer (PC), a mobile phone, a smart phone, a notebook computer, a digital broadcasting terminal, a personal digital assistant (PDA), and a portable multimedia (PMP). Various types of terminals such as a player) and a navigation device.

In the WEB-based presentation service, the presentation real-time synchronization apparatus 100 may include a session generator 101, an extractor 102, a rearrangement unit 103, and a controller 104.

The session generator 101 may generate a session between the presenter terminals 110 and the client terminals 120. For example, when a signal for sharing presentation content is input from the presenter terminal 110, the session generator 101 may generate a sharing URL and generate a session. The presentation real-time synchronization apparatus 100 may transmit the shared URL generated through the communication unit (not shown) to the presenter terminal 110. The presenter terminal 110 may transmit the received sharing URL to the client terminal 120. When the client terminal 120 accesses the shared URL, the presentation real-time synchronization device 100 may synchronize the session. Thus, the presenter terminal 110 and the client terminal 120 may be synchronized.

The extractor 102 may extract at least one object included in each slide of the presentation content. For example, the presentation content includes a plurality of slides, and the extractor 102 may extract objects included in each slide. For example, an object refers to text, a figure, an image, a video, and the like included in the presentation content. The controller 104 may match the attribute information with each extracted object and generate attribute information of the object.

The rearrangement unit 103 may rearrange the rendering order of the object for each slide based on at least one of attribute information of the object, communication state information, and specification information of a connected device. For example, the rearrangement unit 103 weights the attribute information of the object, the communication state information, and the specification information of the connected device, and reorders the rendering order of the object for each slide based on the weighted information. Can be arranged.

The attribute information of the object may include information such as the type, size, color, and data capacity of the object. The communication state information may include information such as a communication speed, a communication method, a traffic state, and the like between the presentation real-time synchronization apparatus 100, the presenter terminal 110, and the client terminal 120. The specification information of the connected terminal may include information such as the data processing speed of the terminal, the size of the display unit, the number of pixels used, the amount of memory, the communication method, and the like. As such, by rearranging the rendering order of the objects in an optimized order, the time for the client terminal 120 to render the presentation content may be minimized.

The rearrangement unit 103 may rearrange the rendering order of the objects in the order in which the processing time is long. A detailed description thereof will be described below with reference to FIG. 2.

The controller 104 can regenerate the presentation content including the rearranged rendering order corresponding to each slide. The controller 104 may share the presentation content reproduced through the session to the client terminal 120. For example, when a signal for executing the presentation content is input from the presenter terminal 110, the controller 104 may share the reproduced presentation content through the generated session.

The controller 104 may search for a client terminal connected for each session, match the presenter terminal, the session and the retrieved client terminal information, and store the information in a memory (not shown). For example, the controller 104 may store and update the client terminal information connected to each session in a memory (not shown) at each set time.

When a signal for executing the presentation content is input from the presenter terminal 110, the controller 104 establishes a session corresponding to the presenter terminal 110 based on matching information stored in a memory (not shown). The reproduced presentation content may be shared to the client terminal 120 through the present invention. A detailed description thereof will be described below with reference to FIG. 3.

The presentation real-time synchronization apparatus 100 may minimize the time for rendering the presentation content by rearranging the rendering order of the objects in the optimized order. Accordingly, the presentation real time synchronization apparatus 100 may share the presentation content with the client terminal without delay.

In addition, the presentation real-time synchronization apparatus 100 shares the presentation content in real time without delay by sharing the presentation content through a session corresponding to the presenter terminal based on matching information stored in the memory without a separate session retrieval process. can do.

1 and 2, the extractor 102 may extract at least one object included in each slide of the presentation content. The extractor 102 may extract the

objects

210, 220, and 230 included in the slide 200. In the present embodiment, the description will be made based on the case of one slide, but a plurality of slides may exist.

The rearrangement unit 103 may rearrange the rendering order of the object for each slide based on at least one of attribute information of the object, communication state information, and specification information of a connected device. For example, the rearrangement unit 103 may rearrange the rendering order of the objects in the order in which the processing time is long.

Hereinafter, it is assumed that the rendering order of the

objects

210, 220, and 230 of the slide 200 is the first object 210, the second object 220, and the third object 230. For example, the rendering order may be the same as the production order in which the object is inserted into the slide.

The rearrangement unit 103 may derive an optimized rendering order in consideration of attribute information of the object, communication state information, specification information of the connected device, and the like. If the optimized rendering order is the third object 230, the first object 210, and the second object 220, the rearrangement unit 103 sets the rendering order of the object for the slide 200 to the third object. 230, the first object 210, and the second object 220 may be rearranged in this order. Accordingly, the client terminal 120 renders and displays the slides in the rearranged rendering order. As such, by shortening the rendering time of the client terminal 120, the presentation content executed in the presenter terminal 110 may be displayed in real time on the client terminal 120.

The controller 104 can regenerate the presentation content including the rearranged rendering order corresponding to each slide. The controller 104 may share the presentation content reproduced through the session to the client terminal 120.

1, 3, and 4, the controller 104 searches for a client terminal connected for each session, matches the presenter terminal, the session, and the retrieved client terminal information to store in the memory (not shown). Can be. In the present embodiment, the presenter terminal 1 is connected to session 1, the terminals connected to session 1 are

client terminals

1 and 2, the presenter terminal 2 is connected to session 2 and session 3, and the terminal connected to session 2 is a client terminal. Assume that 3 and 4 are client terminals connected to

session

3, 5 is presenter terminal 3 is connected to session 4, no terminal is connected to session 4, and so on. The reason there is no terminal connected to session 4 may be that the terminal connected to session 4 has terminated the connection.

When a signal for executing the presentation content is input from the presenter terminal 110, the controller 120 establishes a session corresponding to the presenter terminal 110 based on matching information stored in a memory (not shown). The reproduced presentation content may be shared to the client terminal 120 through the present invention. For example, when a signal for executing the presentation content is input from the presenter terminal 2, the controller 120 does not perform a separate session search, but based on the matching information stored in the memory (not shown), the presenter terminal 2 The reproduced presentation content may be shared to the

client terminals

3, 4, and 5 through Session 2 and Session 3 corresponding to.

Accordingly, the presentation real-time synchronization device can share the presentation content in real time by drastically reducing the time for transmitting the presentation content by sharing the presentation content through the session immediately without a separate session search process.

The presentation real-time synchronization apparatus 100 extracts at least one object included in each slide of the presentation content (510). For example, the presentation content includes a plurality of slides, and the presentation real-time synchronization apparatus 100 may extract objects included in each slide. The presentation real-time synchronization apparatus 100 rearranges the rendering order of the object for each slide based on at least one of attribute information of the object, communication state information, and specification information of a connected device (511). The presentation real-time synchronization apparatus 100 regenerates the presentation content including the rearranged rendering order corresponding to each slide (512).

The presentation real-time synchronization device 100 matches the presenter terminal, the session, and the retrieved client terminal information and stores the matched terminal information in a memory (not shown) (514). For example, the presentation real-time synchronization apparatus 100 may store and update the client terminal information connected to each session in a memory (not shown) at each set time. When the presentation real-time synchronization device 100 receives a signal for executing the presentation content from the presenter terminal 110, the session corresponding to the presenter terminal 110 based on matching information stored in a memory (not shown). The reproduced presentation content is shared with the client terminal 120 through the session (515).
