The present invention relates to a video reproducing technology of a mobile communication terminal, and more particularly, to a technology for reproducing and displaying a screen corresponding to two mobile communication terminals for two screens divided from one screen to the left and right.

Due to the development of wired / wireless communication technology, users have enjoyed playing various types of contents in a mobile communication terminal. Types of contents include contents (pictures, multimedia videos, pictures, animations, games, ringtones, sound source data, etc.) provided by using mobile communication, and contents provided by a cable connection between a PC and a mobile communication terminal. In addition, in the case of a mobile communication terminal having a camera function, the user can play and enjoy contents such as a picture or a video created using the mobile communication terminal on the mobile communication terminal.

In addition, recently, a mobile communication terminal having a broadcast receiving function has been released. Types of broadcast channels include general airwave (TV, radio) broadcasts, and digital broadcast channels operated for a fee. The user can enjoy these broadcast contents using the mobile communication terminal.

As described above, the contents reproduced in the mobile communication terminal are diversified, and the content reproduction function is becoming a main function of the mobile communication terminal, in addition to the inherent communication (telephone and data) function of the mobile communication terminal.

On the other hand, for example, by using a liquid crystal display (LCD) as large as possible, the video content can be more realistically enjoyed. However, since the mobile communication terminal is basically manufactured to be portable, there is a limit to increasing its size.

As a technique for solving such a problem, Korean Laid-Open Patent Publication No. 2004-75433 is known. This publication is for two mobile communication terminals to receive two separate video files, each of which is executed in each mobile communication terminal to form one screen as a whole.

According to the detailed description of the publication, in a method in which two mobile communication terminals according to the publication receive two separate image files, each of which is executed in each mobile communication terminal to configure a screen as a whole, (a) when the two screens corresponding to each of the two screens correspond to each other, the entire screen is configured, and each of the two mobile communication terminals receives each of the video files from a server having two video files having a shared key value. (b) any one of the mobile communication terminals receiving the video file requesting the shared key value from the server to receive the shared key value; and (c) the received shared key value is selected from the mobile communication terminal. If it is input to one and transmitting it to another mobile communication terminal in close proximity, (d) The mobile received the shared key value Characterized by comprising the step of passing the new terminal it is executed concurrent signal to another mobile communication terminal.

Accordingly, when the video screens simultaneously executed in the respective mobile communication terminals correspond to each other, one screen is configured as a whole. In one embodiment, the communication between adjacent mobile communication terminals uses infrared communication. In particular, in the step (c), when the shared key value is input to the mobile communication terminal, the input value is compared with the shared key value of the received image file, and if they match, it is transmitted to another mobile communication terminal in close proximity.

Looking at the concept of the publication as a top-level concept, as shown in the present invention, two mobile communication terminals for each of the two screens divided from one screen to the left and right to reproduce the corresponding screen and display the screen.

However, in view of the manner of implementing the division playback function, the range of usable contents, the convenience, and the like, the present invention is more advanced than the technology described in this publication. Hereinafter, description of the publication will be described in contrast to the present invention.

In the method of the publication, a communication service provider or a content service provider divides one video file into a left screen and a right screen in advance and re-encodes it. Then, two terminals download two video files and play the video on each terminal. That is, what is performed in the two terminals merely adjusts the playback start time of the video file to each other so that the corresponding left and right contents proceed simultaneously. In other words, the actual video data is owned by each of the terminals, and the start signal is transmitted and received through infrared communication in order to match the playback start time of the respective video data.

If the image data is not reworked to the left or right, but the general video file, consider the method of publication. This is a situation where the same video is being played on two terminals at the same time, i.e., multi-vision. As a result, the technology described in the publication is not a technology implemented in the mobile communication terminal itself, but corresponds to a video service technology among mobile communication services.

In addition, according to the publication, a mobile communication service provider or a service provider must separately produce a left image file and a right image file. That is, the area played in one video file is divided in half in advance, that is, the video data for the left screen and the video data for the right screen must be divided and encoded separately, so that the two terminals separately receive each image data wirelessly. do. Therefore, for a few users who want the service of the publication, the operator has to rework all image files used by general terminal users, and has a problem in that the image files are divided into left and right.

In addition, according to the technique described in the publication, real-time playback is not supported in dividing and playing one video file. That is, when two mobile communication terminals receive the left screen file and the right screen file separately, and both of them finish downloading, one of them downloads the shared key value again and uses this value to play the timing at the same time. do. Therefore, the technique described in the publication can be reproduced only after reception of a video file and a shared key value, and thus cannot support real time streaming, for example. In addition, it is not meaningful that only one terminal plays the half-digit image received for divisional reproduction independently, and it becomes a useless thing occupying only memory in the terminal.

The present invention has been devised in such a situation, and the mobile communication terminal, if any terminal is equipped with the appropriate codec and hardware, for the general video data that can be played back, for example, in a software process in real time to the left / right video screen Splitting, recognizing the position relative to the other mobile communication terminal and outputs any one of the video data corresponding to the position of the mobile communication terminal of the divided video data, the other video data is provided to the other mobile communication terminal through the communication interface unit The purpose of the present invention is to propose a method of transmitting to a corresponding communication interface.

In accordance with another aspect of the present invention, there is provided a video reproducing apparatus of a mobile communication terminal, which recognizes a relative position of the mobile communication terminal corresponding to another mobile communication terminal, and includes left position information or right position information corresponding to the position. A control unit for providing a video signal, a codec unit for decoding the video data, and split the decoded video data into left video data and right video data, and according to the position information from the controller, any one of the divided video data. A signal processing unit including an image divider for transferring the image data to the screen display unit and transferring the remaining image data to the communication interface unit, a screen display unit for displaying the divided image data on the screen, and moving the remaining divided image data Transmission to the corresponding communication interface unit provided in the communication terminal It is characterized in that it is configured to include a communication interface.

The foregoing and other aspects of the present invention will become apparent from the following examples. Hereinafter, the present invention will be described in detail with reference to the preferred embodiments described with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is an example of a block diagram showing a video reproducing apparatus of a mobile communication terminal according to a preferred embodiment of the present invention, Figure 2 is a flow chart showing a video reproducing method of a mobile communication terminal according to a preferred embodiment of the present invention Is one example. This will be described with reference to the aforementioned drawings.

According to a preferred embodiment of the present invention, the present invention provides a method for reproducing an image of a mobile communication terminal having a video signal processing function, the method comprising: recognizing a relative position of the mobile communication terminal 201 corresponding to another mobile communication terminal; Decoding the video data (207); dividing the decoded video data into the left video data and the right video data (211); and among the two divided video data according to the position of the mobile communication terminal. It transmits one image data to the screen display unit 115 to display the screen, and transmits the other image data to the corresponding communication interface unit (not shown) provided in the other mobile communication terminal through the communication interface 121 It is characterized by comprising a step (215).

According to a preferred embodiment of the present invention, the baseband circuit of the mobile communication unit 103 and most of the circuits of the control unit 117 may be commercially provided as a single integrated circuit. The integrated circuit may include dedicated hardware for processing communication therein, a digital signal processor and a general purpose microprocessor. Logically, this integrated circuit includes a mobile communication unit 103 for controlling voice and data communication, and a control unit 117 for controlling the entire system in accordance with an operation signal or an operation state input from the operation unit 119. This integrated circuit can be an MSM chip. The signal processor 110 may also be included in the integrated circuit described above, but in some cases, may be implemented as a separate image processor in consideration of the processing capacity of the integrated circuit.

In the present invention, instead of receiving the left image or the right image from the external server as in the prior art, the mobile communication terminal itself separates the image, and one (eg, the main terminal) outputs one of the separated images and displays the other one. Transmits to another mobile communication terminal (eg secondary terminal). Accordingly, according to a characteristic aspect of the present invention, the control unit 117 recognizes the relative position of the mobile communication terminal in response to the other mobile communication terminal and displays the left position information or the right position information corresponding to the recognized position of the image segmentation unit 111. To provide.

There may be various ways for the controller 117 to recognize the relative position of the mobile communication terminal corresponding to the other mobile communication terminal. As an example, there may simply be a way for the user to directly set through the operation unit 119. For example, if the mobile communication terminal is set to the left through the operation unit 119, the control unit 117 recognizes this and outputs the left image data through the screen display unit 115 among the divided image data, and communicates the right image data. It transmits to another mobile communication terminal (not shown) through the interface unit 121. Another example of recognizing the relative position will be described later.

According to a preferred embodiment of the present invention, the signal processor 110 may be implemented including a codec unit 109 and an image divider 111. The codec unit 109 decodes the image data (207), for example, may be a conventional MPEG4 codec.

In addition, according to a characteristic aspect of the present invention, since the present invention is operable to the video data decodable by the codec unit 109, the video data is downloaded or downstreamed from an external server (not shown), and the mobile communication unit ( 103). In addition, the image data to be photographed may be transmitted from the camera unit 105, and as broadcast received image data, may be delivered from the broadcast receiving unit 101. In addition, the image data may be data stored in the storage unit 107.

In addition, according to the present invention, the image segmentation unit 111 divides the decoded image data of one screen into the left image data and the right image data (211), and according to the position of the mobile communication terminal, of the divided image data One image data is transmitted to the screen display unit 115 to display the image, and the other image data is transmitted to the corresponding communication interface unit (not shown) provided in the other mobile communication terminal through the communication interface unit 121. (215).

As is well known, the signal processor does not immediately transfer the decoded image data to the screen display 115 immediately after being decoded. Instead, the signal processor temporarily writes the decoded image data to the storage unit 107 (e.g., PAGE RAM). It can be read and transferred to the screen display unit 115.

Therefore, according to an embodiment of the present invention, the image segmentation unit 111 first writes the image data (general image data) decoded by the codec unit 109 to the storage unit 107. The image divider 111 refers to the position information input from the controller 117. Thus, when the relative position of the mobile communication terminal corresponds to the left side, half of the data corresponding to the left side of the image data stored in the storage unit 107 is read and transmitted to the screen display unit 115 side, and corresponding to the remaining right side The half of the data is read and transmitted to another mobile communication terminal through the communication interface 121.

For example, if the pixel size of the decoded image data is (480 pixels wide x 320 pixels wide), the (240 pixels wide x 320 pixels wide) of the left region (1 pixel to 240 pixels wide) of the entire image data of the page RAM is determined. The cutout is transmitted to the screen display unit 115, and (240 pixels × 320 pixels) of the right area (from 241 pixels to 480 pixels) of the entire image data of the page RAM is cut out and then transferred to the screen display unit 115 through the communication interface 121. Transmit to other mobile communication terminal.

The technology itself for communicating user data (including image data) and various control signals by setting up a wired / wireless communication interface promised between two mobile communication terminals of the same type (PHONE-TO-PHONE) is provided. It is a technique known in the art prior to filing. As the communication method of the communication interface 121, for example, there may be cable communication such as infrared communication or RS-232C.

As described above, according to a preferred embodiment of the present invention, instead of receiving a left image or a right image from an external server as in the prior art, the mobile communication terminal itself separates the image and decomposes any one of the separated images. The primary terminal outputs the screen and transmits the other one to another mobile communication terminal (eg, secondary terminal). Accordingly, in the present invention, the controller 117 recognizes the relative position of the mobile communication terminal in response to the other mobile communication terminal, and transfers the left position information or the right position information corresponding to the recognized position to the image segmentation unit 111. to provide.

In addition, according to a characteristic aspect of the present invention, since the present invention operates on the image data decodable by the codec unit 109, the image data is downloaded or downstreamed from an external server (not shown), and the mobile communication unit is performed. May be passed from 103. Also, the image data may be transmitted from the camera unit 105 as image data to be photographed, and may be transmitted from the broadcast receiving unit 101 as broadcast image data. In addition, the image data may be data stored in the storage unit 107.

Meanwhile, according to an additional aspect of the present invention, the codec unit 109 resizes the pixel size of the video data to be decoded to be equal to the pixel size of the screen display unit 115 at the request of the controller 117. Characterized in further performing the operation.

According to an embodiment of the present invention, the liquid crystal display of each mobile communication terminal has a predetermined pixel size capable of displaying image data. For example, if the liquid crystal display device is QVGA, the pixel size is (240 pixels wide x 320 pixels high). Therefore, when the video data output from the codec unit 109 is divided left and right, it is preferable that the pixel size of each divided video data is a pixel size of (240 pixels in length x 320 pixels in length), respectively.

In one embodiment, when the decoded image data output from the codec unit 109 is a pixel size of (480 pixels by 320 pixels in length), the pixel size of each divided image data is (240 pixels in width × each). The pixel size is 320 pixels in height, so no additional processing is required.

In one embodiment, the video data reproduced on the screen of one mobile communication terminal is to be played over each screen of the two mobile communication terminals. Therefore, if image data of pixel size that can be reproduced in the screen window of one terminal is downloaded from an external server, the pixel size of the downloaded image data must be enlarged in order to be reproduced over each screen window of two terminals. do.

That is, the decoded image data output from the codec unit 109 is a pixel size of (240 pixels wide x 320 pixels), and the liquid crystal display of each mobile communication terminal has a pixel size of (240 pixels wide x 320 pixels). In this case, it is necessary to allow each image data to be divided to have a pixel size of (240 pixels wide x 320 pixels high).

To this end, according to an embodiment of the present invention, the control unit 117 makes a resizing request requesting the codec unit 109 to adjust the pixel size of the image data output. In one embodiment, in the case of the MPEG4 codec, an instruction code corresponding to resizing is added during programming.

Thus, for example, the codec unit 109 additionally performs a resizing process so that the image data can be output at a pixel size of (480 pixels × 320 pixels) in decoding. Implementation methods for resizing using the MPEG4 codec are well known in the art. For example, in the original image data, if one liquid crystal display device pixel corresponds to one pixel (for example, RGB) value constituting the image, one pixel value (original image data) is changed at the request of the controller 117. Two liquid crystal display pixels are output (see FIG. 7). Of course, one pixel value may be output to two half or three liquid crystal display pixels according to the requested size to be resized.

According to a further aspect of the present invention, a mobile communication terminal has a left connector part and a right connector part respectively coupled to a corresponding connector part provided in another mobile communication terminal on a left side and a right side of the housing.

5, the left side of the mobile communication terminal housing has a left connector 501. For example, the left connector 501 may be implemented as a receptacle for allowing a corresponding plug to be inserted, such as a receptacle for providing a USB plug to a USB terminal.

In addition, the right side of the mobile communication terminal housing has a right connector 503. For example, the right connector 503 is typically provided in a portable terminal such as a USB plug, and may be a plug that can be plugged into a receptacle.

6 shows a state in which a mobile communication terminal and another mobile communication terminal are coupled by a connector unit. The other mobile communication terminal also has a left connector 601 on the left side of the housing, and a right connector 603 on the right side.

As shown, the right connector 503 of the mobile communication terminal and the left connector 601 of the other mobile communication terminal are combined. As such, when the two mobile communication terminals are communicatively connected by the direct coupling of the connector parts 503 and 601 on the left side of the mobile communication terminal and the right side of the other mobile communication terminal, the two liquid crystal display devices are also in close proximity. Since the data is reproduced in succession, the user can enjoy the contents in a more realistic wide screen window.

At this time, the communication interface 121 performs communication through the right connector 503 coupled with the left connector (eg, 601) of the other mobile communication terminal, or the communication interface 121 is connected to the other mobile communication terminal. Communication is performed through the left connector 501 coupled with the right connector (eg, 603).

When the controller 117 recognizes that it is coupled with another mobile communication terminal through the communication interface 121, the position of the mobile communication terminal depends on whether the connector part connected to the other mobile communication terminal is the left connector part or the right connector part. It recognizes (201). For example, the control unit 117 recognizes the relative position of the mobile communication terminal as the left connector part when the connector part connected to the other mobile communication terminal is the left connector part, and when the connector part connected to the other mobile communication terminal is the left connector part, the mobile communication terminal Recognize the relative position of to the right.

According to an auxiliary aspect of the present invention, the left connector portion may be a receptacle portion, and the right connector portion may be a plug portion. Alternatively, the right connector portion may be a plug portion, and the left connector portion may be a receptacle portion.

Accordingly, for example, the connector part of the present invention may be implemented as a receptacle part commonly implemented in a portable terminal using a USB cable and a plug part commonly implemented in the portable terminal so as to be directly connected to a host without using a USB cable.

According to an additional aspect of the present invention, the buffer unit 113 buffers the divided image data, and transfers the buffered image data to the screen display unit 115, and in accordance with the buffering state, the communication interface unit ( And transmitting a synchronous control signal to another mobile communication terminal (not shown) through 121).

This additional aspect proposes a concrete implementation method for synchronizing the images played back in two mobile communication terminals. It is obvious to those skilled in the art that the synchronization control signal is transmitted to the counterpart terminal according to the buffering state of the buffer unit, and the two terminals synchronize time. Therefore, a detailed description thereof will be omitted.

For reference, in the case of the mobile communication terminal of FIG. 1, two communication interface units 121 and 313 and two coupling units 503 are used in the case of the mobile communication terminal of FIG. 3. , 601), so that time delay may occur. If this time delay is fine enough to be tolerated, then no additional time synchronization establishment measures will be needed. In order to overcome this time delay, the present invention uses a means of buffering as an embodiment.

3 is another example of a block diagram illustrating a video reproducing apparatus of a mobile communication terminal according to a preferred embodiment of the present invention, and FIG. 4 is a flowchart illustrating a video reproducing method of a mobile communication terminal according to a preferred embodiment of the present invention. Is another example. Hereinafter, a description will be given with reference to the drawings described above. In the description, the description of unnecessary portions will be omitted.

If the primary terminal and the secondary terminal have not yet been determined, the two mobile communication terminals must prepare for the video segmentation playback operation in the same environment. Therefore, the mobile communication terminal performing the operation of FIG. 4 first needs a location recognition step. In some cases, the controller 315 may inform the position information recognized by the signal processor 310 in advance.

In one embodiment, whether the primary terminal and the secondary terminal can be determined by the user's play play command signal. For example, when a user's video reproduction command is input through the operation unit 119 in FIG. 2 (203), the controller 117 recognizes that the user is the main terminal, and recognizes the communication interface 121, 313. This is notified to the control unit 315 of the other mobile communication terminal (205). Then, the control unit 315 can recognize that it is the secondary terminal (403), and then waits for example to receive the image data. Subsequently, when the divided image data is received through the communication interface unit 313, the image data is output through the screen display unit 301 (409).

Meanwhile, according to an exemplary embodiment, the signal processor 310 may temporarily store image data received through the communication interface 313. For example, the image data may be written to the page RAM of the storage unit 305. As described above, whether the received image data is directly transmitted from the communication interface unit 313 to the screen display unit 301 or through another temporary storage means (for example, the signal processor 310) is provided. This is not an important issue in describing this, but is a problem that you may face in your implementation. Of course, what is delivered directly to the screen display unit 301 may achieve better performance in simultaneous playback.

In addition, when two mobile communication terminals are communicatively connected by the direct coupling of the connector of the left side of the mobile communication terminal and the right side of the other mobile communication terminal, the two liquid crystal display devices are also in close proximity, so that the two image data are reproduced in succession. Since it brings, the user can more realistically enjoy the content in a wide screen window occurs.

In addition, according to the present embodiment, the mobile communication terminal (sub terminal) does not receive a left image or a right image from an external server as in the prior art, but from another mobile communication terminal (main terminal) (the other mobile communication terminal itself). Separating the image) Any one of the separated images is received.

According to a characteristic aspect of the present invention, any mobile communication terminal corresponding to the present invention may be either a primary terminal or a secondary terminal. If the primary terminal and the secondary terminal have not yet been determined, the two mobile communication terminals must prepare for the video segmentation playback operation in the same environment.

Therefore, whether the primary terminal or the secondary terminal, the mobile communication terminal first needs a location recognition step. In some cases, the controller may inform the position information recognized by the signal processor in advance.
