Description

[0001] MOBILE TERMINAL AND VIDEO SHARING METHOD THEREOF [0002]

The present invention relates to a mobile terminal capable of freely changing a video sharing right and performing video sharing in both directions and a method for changing a video sharing right.

The mobile terminal may be configured to perform various functions. Examples of such various functions include a data and voice communication function, a function of photographing a video or a moving image through a camera, a voice storage function, a music file playback function through a speaker system, and an image or video display function.

Some mobile terminals include additional functions to execute games, and some other mobile terminals are also implemented as multimedia devices. Moreover, recent mobile terminals can receive a broadcast or multicast signal to view a video or television program.

Among them, the touch function of the mobile terminal allows the user who is not familiar with the button / key input to conveniently perform the operation of the terminal by using the touch screen. In recent years, not only simple input but also important function .

Recently, a mobile terminal provides a video sharing call (VSC) function that transmits a video image (video signal) captured by a camera or a pre-stored video in a communication mode in which a voice signal is transmitted and received to a correspondent terminal in real time. In this case, the mobile terminal uses RTP (Real Time Protocol) to transmit voice data and uses PDP (Packet Data Protocol) to transmit video data.

Accordingly, the mobile terminal establishes a session (or a call) with the other party using a SIP (Session Initiation Protocol), which is a signaling protocol, and then sets up a session (or call) with the other party and then transmits the APN (Access Point Name) of the IP_based Multimedia Subsystem And performs the VSC function based on the assigned IP.

However, in the VSC function currently provided in the mobile terminal, a person who sends an image (MO) and a person who receives an image (MT) are determined before using the image sharing function. Therefore, if the MT wants to send an image to the MO during video sharing, it has a drawback in that it is necessary to stop the image sharing operation during the connection (disconnect the session) and perform the image sharing function again.

The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and a broadcast signal in which a data broadcast signal is combined with a TV broadcast signal or a radio broadcast signal.

Meanwhile, the broadcast related information may be provided through a mobile communication network, and in this case, it may be received by the mobile communication module 112.

The broadcast-related information may exist in various forms. For example, an EPG (Electronic Program Guide) of DMB (Digital Multimedia Broadcasting) or an ESG (Electronic Service Guide) of Digital Video Broadcast-Handheld (DVB-H).

The broadcast receiving module 111 receives broadcasting signals using various broadcasting systems. In particular, the broadcasting receiving module 111 may be a Digital Multimedia Broadcasting-Terrestrial (DMB-T), a Digital Multimedia Broadcasting-Satellite (DMB-S) Only Digital Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T), and the like. Of course, the broadcast receiving module 111 is configured to be suitable for all broadcasting systems that provide broadcasting signals as well as the digital broadcasting system described above.

The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

In addition, the mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and the wireless Internet module 113 can be built in or externally. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

The short-range communication module 114 refers to a module for short-range communication. Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, and the like can be used as the short distance communication technology.

The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. A typical example of the position information module 115 is a Global Position System (GPS) module. According to the present technology, the GPS module calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain three-dimensional current position information according to latitude, longitude, and altitude It can be calculated accurately. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display module 151.

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

The user input unit 130 generates input data for a user to control the operation of the terminal. The user input unit 130 may include a key pad, a dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. Particularly, when the touch pad has a mutual layer structure with the display module 151 described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence or absence of user contact, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be discussed later in connection with touch screens.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, Video input / output (I / O) ports, earphone ports, and the like.

Here, the identification module is a chip that stores various information for authenticating the use right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device.

The interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, Various command signals may be transmitted to the mobile terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display module 151, an audio output module 152, and an alarm unit 153.

The display module 151 displays and outputs information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display module 151 and the touch pad have a mutual layer structure to constitute a touch screen, the display module 151 can be used as an input device in addition to the output device. The display module 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent organic light emitting diode (TOLED) or the like. In addition, there may be two or more display modules 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may be provided with an external display module (not shown) and an internal display module (not shown) at the same time. The touch screen may be configured to detect not only the touch input position and area but also the touch input pressure.

Meanwhile, the proximity sensor 141 may be disposed inside or near the touch screen. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. Therefore, the proximity sensor 141 has a considerably long life span and its utilization is also significantly higher than that of the contact-type sensor.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

An example of the operation of the high-frequency oscillation-type proximity sensor will be described. In a state where a high frequency of a stationary wave is oscillated in an oscillation circuit, when the sensing object approaches the vicinity of the sensor sensing surface, the oscillation amplitude of the oscillation circuit attenuates or stops , And these changes are converted into electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor 141 may be configured so as to detect the proximity of the pointer with the change of the electric field along the proximity of the pointer if the touch screen is electrostatic.

Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; In addition, a position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects proximity touches and proximity touch patterns (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, and the like) , And may output information corresponding to the detected proximity touch operation and the proximity touch pattern on the touch screen.

The audio output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 152 outputs an acoustic signal related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the vibration output as described above. Of course, a signal for notifying the occurrence of an event may also be output through the display module 151 or the sound output module 152.

The memory 160 may store a program for processing and controlling the control unit 180 and may store a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, . In addition, the memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read- And an optical disc. Also, the mobile terminal 100 may operate a web storage for performing a storage function of the memory 160 on the Internet.

The control unit 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

The mobile terminal 100 mainly operates in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The mobile terminal 100 operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

The casing (casing, housing, cover, etc.) constituting the outer appearance of the first body 200 is formed by the first front case 220 and the first rear case 225. Various electronic components are embedded in the space formed by the first front case 220 and the first rear case 225. At least one intermediate case may be additionally disposed between the first front case 220 and the first rear case 225.

The cases may be formed by injection molding of a synthetic resin or may be formed of a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the sound output module 152, the camera 121 or the first user input unit 210 may be disposed in the first body 200, specifically, the first front case 220.

The mobile terminal provides a Video Sharing Call (VSC) function that transmits a video image (video signal) stored in a pre-stored image or a camera in a communication mode in which a voice signal is transmitted and received to a correspondent terminal in real time. The user of the mobile terminal establishes a session with a user who wants to share the video and then shares the video through the session. At this time, the user (or sender) who wants to share the image is referred to as MO, and the user (or receiver) who receives the image is referred to as MT.

5 is a signal flow diagram for performing image sharing in a conventional one-to-one call.

As shown in FIG. 5, the user MO transmits a session establishment request (INVITE) message to the user MT in order to share an image. In the INVITE message, a user (MO) can receive a certain type of image to a user (MT) and a location to which the image is to be transmitted may be included. The INVITE message passes through several SIP servers (not shown) to be delivered to the MT. The SIP server is implemented as a proxy server having only a message forwarding function.

The SIP server that received the INVITE message parses the INVITE message to recognize the MT 50, and then delivers the INVITE message to another appropriate SIP server or MT.

The MT receiving the INVIT message sends a response message to the INVITE message. The response message includes a status code indicating a processing result. If the MT has successfully received and processed the INVITE message, it sends a '200 OK' response message to the MO. Upon receiving the response message, the MO transmits an ACK request message to the MT again to notify that the response message (200 OK) sent from the MT has been properly received, thereby creating one session between the MO and the MT.

Accordingly, the MO transmits an image to be shared through a set session, for example, a pre-stored image or an image (video signal) captured by the camera, to the MT in real time. In the present invention, for convenience of description, image sharing in a one-to-one call is defined as "individual image sharing ".

Referring to FIG. 6, an operation in which a user (MO) sends a session establishment request (INVITE) message to a user MT1 to establish a session is the same as in FIG. The MO can perform voice communication with the MT1 through the established session (for example, session 1), and requests the other user MT2 to establish a session while performing the voice communication with the MT1, Similarly, session setup may be requested from MT2.

When the INVITE message requesting the session setup is received from the user MT2, the MO transmits the processing result of the INVITE message to the MT2 in response to the response message (200 OK). The MT2 receiving the response message generates another session (for example, session 2) between the MO and the MT2 by transmitting an ACK request message to the MO again to notify that the response message (200 OK) sent from the M has been properly received.

Accordingly, the MO transmits a pre-stored image or an image photographed by the camera to each of MT1 and MT2 through each session 1 and session 2 to perform a multi-image sharing function.

For convenience of explanation, the present invention defines a video sharing in a one-to-many conversation as "multi-view video sharing ".
