Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The present invention proposes a method and apparatus for displaying e-book contents in a multi-screen device system.

FIG. 1 is a diagram schematically illustrating a structure in which a first device is connected to peripheral devices in a multi-screen device system.

Referring to FIG. 1, it may be assumed that the first device 100 may be simultaneously connected to a plurality of devices, and the first device 100 is an example of a tramway device. That is, the first device 100 may be connected to the second device 110 to the N-th device 120, and may share content with the connected devices. Here, the second device 110 to the Nth device 120 may be all terminals having a screen capable of displaying shared content such as a tram book, a smartphone, a tablet PC, and the like.

2 is a signal flowchart illustrating a procedure of displaying content according to a service display type in a multi-screen device system.

Referring to FIG. 2, when a first device 200, for example, an e-book device, detects a multi-rendering service requesting to share content currently being displayed with another device (step 203), it searches for neighboring devices. The message is broadcasted (step 205). The discovery message includes capability information of the first device 200, and the capability information indicates whether devices receiving the discovery message can display the content being displayed on the first device 200. It is the basis for judging.

The devices receiving the discovery message transmit a discovery response message to the first device 200 in response to the discovery message (step 207). The search response message includes control related capability information on whether the user can display the content being displayed on the first device.

The first device 200 selects at least one device to share and display the content displayed in the first device 200 among the neighboring devices based on the received discovery response message (step 209). In FIG. 2, it is assumed that the first device 200 selects the second device 250.

In operation 211, the first device 200 determines a service display type. The service display type is determined as one of an interworking service display type, a subordinate service display type, and an independent service display type.

Here, the companion service display type indicates a service display type in which a control event occurring in the first device 200 also affects the second device 250. For example, the case where one electronic book is displayed through the first device 200 and the second device 250 may correspond to the companion service display type. For example, in the interlocking service display type, an even page is displayed on the first device 200, an odd page is displayed on the second device 250, and a control event such as turning over a bookshelf is generated on the first device 200. Similarly, the control event is applied to the second device 250 to reflect the effect of turning over the bookshelf.

The standalone service display type indicates a service display type in which a control event generated in the first device 200 does not affect the second device 250. For example, when the reference list of the text is clicked while the first device 200 displays the article, the body of the article is displayed on the first device 200 and the reference is popped up on the second device 250. The case of being displayed may correspond to the independent service display type.

For example, the first device 200 displays the body of the book and the second device 250 displays only the video inserted into the book, but is displayed on the second device 250 through the first device 200. This is the case where the content can be controlled.

When the first device 200 shares the content displayed on the first device 200 with the second device 250, the first device 200 indicates a relationship indicating the relationship between the first device 200 and the second device 250. In operation 213, the message is transmitted to the second device 250. The relationship setting message may include, for example, location relationship information such as whether to display a left or right page in an e-book, a top or bottom of the corresponding page, and an e-book, for example, whether to operate as a master device or a slave device. And at least one of relationship information such as main / sub relationship information such as the like and each device operating independently.

After the first device 200 transmits the relationship setting message, the first device 200 completes the relationship setting according to the information indicated by the relationship setting message, and the second device 250 also completes the relationship setting according to the information indicated by the relationship setting message. (Step 215)

After completing the relationship between the first device 200 and the second device 250, when the control event is detected (step 217), the first device 200 generates a control event message indicating the control event. Transmit to device 250 (step 221). The second device displays the corresponding content on the screen in consideration of the control event and the service display type (step 225). The first device also displays the corresponding content on the screen in consideration of the control event and the service display type (step 223). The control event may be a page using the first device 200, that is, a user using an e-book, page turning, scrolling a screen, enlarging or reducing the screen, playing a video, or displaying a pop-up window of the content.

Here, an example in which the display implementation method of each of the first device 200 and the second device 250 is the same is described as an example. However, when the display implementation method of each of the first device 200 and the second device 250 is different, the control event message is converted to correspond to the implementation method of the second device 250 so that the second device ( 250). For example, the display implementation method may be the same when the same model is the same manufacturer, and may be different when the model is the same or different model. That is, when the display implementation schemes of the first device 200 and the second device 250 are different from each other, the first device 200 sends a message indicating a control event detected in step 217 to the second device 250. According to the implementation manner of the conversion (step 220), and transmits the converted control event message to the second device 250 (step 221).
