1 is a diagram schematically illustrating an example of a digital system including a digital device according to the present invention.

1, an example of a digital system including a digital device according to the present invention includes a content provider (CP) 10, a service provider (SP) 20, a network provider A network provider (NP) 30 and a home network end user (HNED) (Customer) 40. Here, the HNED 40 may be, for example, a network TV, a smart TV, an IPTV, etc., as described above as the client 100, i.e., a digital device according to the present invention.

The content provider 10 produces and provides various contents. As shown in FIG. 1, the content provider 10 may include a terrestrial broadcaster, a cable SO (System Operator) or MSO (Multiple SO), a satellite broadcaster, An Internet broadcaster, a private CPs, etc. The content provider 10 may provide various applications besides broadcast content, etc. In this regard, I will explain in detail.

The service provider 20 can package and provide the content provided by the content provider 10 in a service. For example, the service provider 20 of FIG. 1 can package and provide the first terrestrial broadcast, second terrestrial broadcast, cable MSO, satellite broadcast, various Internet broadcasts, applications, etc. to the user.

Meanwhile, the service provider 20 can provide a service to the client 100 side in a uni-cast or multi-cast manner. In the above, the unicast method is a method of transmitting data between one sender and one receiver at a ratio of 1: 1. For example, in the case of a unicast method, when a receiver requests data from a server, the server transmits the data to the receiver according to a request. On the other hand, the multi-cast method is a method of transmitting data to a plurality of recipients of a specific group. For example, a server transmits data to a plurality of pre-registered receivers at a time. An Internet Group Management Protocol (IGMP) protocol may be used for the multi-cast registration.

Also, the content provider 10 and the service provider 20 may be the same entity. For example, the content provider 10 can also perform the functions of the service provider 20 by producing content and providing it in a service package. The opposite is also possible.

The network provider 30 may provide a network for exchanging data between the server and the client 100. [

The client 100 can construct a home network and transmit / receive data.

On the server side in the digital system, conditional access or content protection may be used to protect the transmitted content. In this case, on the client 100 side, a means such as a cable card (CableCARD), a DCAS (Downloadable CAS) or the like can be used for the processing in response to the server-side restrictive reception or content protection.

In addition, the client 100 can use the two-way service through the network. In this case, the client 100 may perform the function of the content provider, and the existing service provider 20 may receive it and transmit the same to another client.

2 is a diagram illustrating an example of a digital device according to the present invention. Here, FIG. 2 may correspond to the client of FIG. 1, for example, and may be a digital television receiver.

In one embodiment, an example of a digital device to which at least one external input is connected includes an interface for receiving a user input, a receiver for receiving content via a broadcast signal or a connected external input, a UI And a display unit for outputting at least one of a cursor and a UI according to the selected input mode and a display unit for outputting the content.

Here, the controller may control at least one of the color and shape of at least one of the cursor and the UI to be differentiated according to a result of the similarity determination, and may identify the selected input mode together with at least one of the output cursor and the UI Information is output to a predetermined area on the screen, and at least one of audio and vibration for at least one of the output cursor and the UI is output together.

The control unit controls the input mode selection UI according to the state of the digital device and provides the input mode selection UI in response to a wake-up request of the user when the state of the digital device is the stand-by mode In configuring the input mode selection UI, at least one of the shape, color, and size of the icon according to each input mode can be controlled to be configured differently.

In addition, when one input mode is selected from the input mode selection UI, the control unit controls to reconfigure at least one of the configured cursor and UI according to the selected input mode, and the input mode selection UI includes a window for selecting an input mode, The input mode selection UI is provided around the position where the cursor is first activated, and the selected input mode information is displayed at the time when the wake-up ends or when the digital device It is possible to continue to provide the second state described above, that is, until the time when the content starts to be normally provided through the screen.

The digital device 200 includes a network interface 201, a TCP / IP manager 202, a service delivery manager 203, an SI decoder 204, A demultiplexer (Demux) 205, an audio decoder 206, a video decoder 207, a display A / V and OSD module 208, a service control manager A Service Discovery Manager 210, an SI & Metadata DB 211, a Metadata Manager 212, a Service Manager 213, a UI A manager 214 and the like. The network interface unit 201, the TCP / IP manager 202, the service delivery manager 203, the service control manager 209, the service discovery manager 210, The data manager 212, the IMS gateway 250, and the like may be implemented as one module as needed. Other components may also be implemented as a single module or divided into a plurality of modules as needed.

The network interface unit 201 receives or transmits Internet Protocol (IP) packets through a network. That is, the network interface unit 201 receives the service, the content, and the like from the service provider 20 through the network.

The TCP / IP manager 202 is used to transmit IP packets received by the digital device 200 and IP packets transmitted by the digital device 200, that is, between the source and the destination I am involved. The TCP / IP manager 202 classifies the received packets so as to correspond to an appropriate protocol and transmits the packets to the service delivery manager 205, the service discovery manager 210, the service control manager 209, the metadata manager 212, And outputs classified packets.

The service delivery manager 203 is responsible for controlling the received service data. For example, RTP / RTCP can be used to control real-time streaming data. When the real-time streaming data is transmitted using the RTP, the service delivery manager 203 parses the received data packet according to RTP and transmits it to the demultiplexer 205 or to the service manager 213 And stores it in the SI & meta data database 211. And feedbacks the network reception information to the server providing the service using the RTCP.

The demultiplexer 205 demultiplexes the received packets into audio, video, SI (System Information) data, and transmits them to the audio / video decoder 206/207 and the SI decoder 204, respectively.

The SI decoder 204 decodes, for example, service information such as PSI (Program Specific Information), PSIP, DVB-SI, and the like.

In addition, the SI decoder 204 stores the decoded service information in the SI & meta data database 211, for example. The stored service information can be read out and used by a corresponding configuration, for example, by a user's request. SI information related to an EPG service, a channel browser service, or the like according to a user's request can also be read from the SI & meta data database 211 in connection with the present invention. However, a more detailed description thereof will be described later.

The audio / video decoder 206/207 decodes the demultiplexed audio data and video data in the demultiplexer 205. The decoded audio data and video data are provided to the user through the display unit 208. [

The application manager can be configured, for example, including the UI manager 214 and the service manager 213. [ The application manager manages the overall state of the digital device 200, provides a user interface, and can manage other managers.

When an external input is connected to the digital device 200, the application manager or the control unit (not shown) judges the similarity of the configuration such as the shape, color, and size of the cursor, UI, etc. according to each input, Changes the configuration of the cursor, UI, etc. for input, and controls it to be different from the basic cursor, UI, and the like. When the status of the digital device 200 is in the first state, the application manager or the control unit constructs and provides a wake-up list UI according to necessity through an application or the like through an instant boot or the like, And controls to switch to the second state according to the selected input mode through the full boot.

The UI manager 214 provides a GUI (Graphic User Interface) for a user by using an OSD (On Screen Display) or the like, and receives a key input from the user to perform an operation of the device according to the input. For example, upon receipt of a key input from the user regarding channel selection, the key input signal is transmitted to the service manager 213.

The service manager 213 controls a manager associated with a service such as the service delivery manager 203, the service discovery manager 210, the service control manager 209, and the metadata manager 212.

Also, the service manager 213 creates a channel map and selects a channel using the channel map according to the key input received from the user interface manager 214. The service manager 213 receives channel service information from the SI decoder 204 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 205. The PID thus set is used in the demultiplexing process described above. Accordingly, the demultiplexer 205 filters audio data, video data, and SI data using the PID.

The service discovery manager 210 provides information necessary for selecting a service provider that provides the service. Upon receiving a signal regarding channel selection from the service manager 213, the service discovery manager 210 searches for the service using the information.

The service control manager 209 is responsible for selection and control of services. For example, when a user selects IGMP or RTSP in the case of selecting a live broadcasting service such as an existing broadcasting system and selects a service such as VOD (Video On Demand), RTSP is used to select a service Selection, and control. The RTSP protocol may provide a trick mode for real-time streaming. In addition, the service control manager 209 can initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

The metadata manager 212 manages the metadata associated with the service and stores the metadata in the SI & metadata database 211.

The SI & meta data database 211 stores service information decoded by the SI decoder 204, meta data managed by the meta data manager 212, and information necessary for selecting a service provider provided by the service discovery manager 210 do. In addition, the SI & meta data database 211 may store set-up data for the system and the like.

The SI & meta data database 211 may be implemented using a non-volatile RAM (NVRAM) or a flash memory.

Meanwhile, the IMS gateway 250 is a gateway for collecting functions necessary for accessing the IMS-based IPTV service.

On the other hand, the digital device shown in Figs. 2 and 3 is an example according to the present invention, and each component can be integrated, added, or omitted according to specifications of a digital device actually implemented. That is, if necessary, two or more components may be combined into one component, or one component may be divided into two or more components. In addition, the functions performed in each block are intended to illustrate the embodiments of the present invention, and the specific operations and apparatuses do not limit the scope of the present invention.

Other examples of the video signal processing apparatus include a set-top box, a DVD player, a Blu-ray player, a game machine, a computer, and the like described above excluding the display unit 380 and the audio output unit 385 shown in FIG. 3 Can be illustrated.

4 is a block diagram showing an example of the configuration of the controller 370 shown in FIG. The control unit 370 will be described in more detail with reference to FIGS. 3 and 4. FIG.

One example of the control unit 370 according to the present invention includes a demultiplexing unit 410, an image processing unit 420, an on-screen display (OSD) generating unit 440, a mixer 450, A Frame Rate Conveter (FRC) 455 and a formatter 460. The control unit 370 may further include a voice processing unit and a data processing unit. Meanwhile, the mixer 450, the frame rate converting unit 455, and the formatter 460 may be implemented as one module as needed.

The demultiplexer 410 demultiplexes the input stream. For example, the demultiplexing unit 410 may demultiplex the received MPEG-2 TS video, audio and data signals. The stream signal input to the demultiplexer 410 may be a stream signal output from the tuner 310 or the demodulator 320 or the external device interface 335.

The image processing unit 420 performs image processing of the demultiplexed image signal. To this end, the image processing unit 420 may include a video decoder 425 and a scaler 435.

The video decoder 425 decodes the demultiplexed video signal and the scaler 435 scales the decoded video signal so that the resolution of the decoded video signal can be output from the display unit 380.

The video decoder 425 may support various standards. For example, the video decoder 425 performs the function of an MPEG-2 decoder when the video signal is encoded in the MPEG-2 standard, and the video decoder 425 encodes the video signal in the DMB (Digital Multimedia Broadcasting) It can perform the function of the H.264 decoder.

On the other hand, the video signal decoded by the image processing unit 420 is input to the mixer 450.

The OSD generating unit 440 generates OSD data according to a user input or by itself. For example, the OSD generating unit 440 generates data for displaying various data in a graphic or text form on a screen of the display unit 380 based on a control signal of the user input interface unit 350, . The generated OSD data includes various data such as a user interface screen of the digital device 300, various menu screens, a widget, an icon, and audience rating information.

The OSD generation unit 440 may generate data for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 450 mixes the OSD data generated by the OSD generator 440 and the video signal processed by the video processor 320 and provides the mixed video signal to the formatter 460. Since the decoded video signal and the OSD data are mixed, the OSD is overlaid on the broadcast image or the external input image.

A frame rate conversion unit (FRC) 455 converts the frame rate of an input image. For example, the frame rate converter 455 may convert the frame rate of the input 60 Hz image to have a frame rate of 120 Hz or 240 Hz according to the output frequency of the display unit 380, for example. As described above, there are various methods for converting the frame rate. For example, when the frame rate is changed from 60 Hz to 120 Hz, the frame rate conversion unit 455 may insert the same first frame between the first frame and the second frame, Three frames can be inserted. As another example, when the frame rate is converted from 60 Hz to 240 Hz, the frame rate conversion unit 455 may insert and convert three or more identical or predicted frames between existing frames. On the other hand, when the frame conversion is not performed, the frame rate conversion unit 455 may be bypassed.

The formatter 460 changes the output of the input frame rate conversion unit 455 to match the output format of the display unit 380. For example, the formatter 460 may output R, G, and B data signals, and the R, G, and B data signals may be output as low voltage differential signaling (LVDS) . When the output of the input frame rate conversion unit 455 is a 3D video signal, the formatter 460 outputs the 3D format video signal in accordance with the output format of the display unit 380, May also support 3D services.

On the other hand, the voice processing unit (not shown) in the control unit 370 can perform the voice processing of the demultiplexed voice signal. Such a voice processing unit (not shown) may support processing various audio formats. For example, even when a voice signal is coded in a format such as MPEG-2, MPEG-4, AAC, HE-AAC, AC-3, or BSAC, a corresponding decoder can be provided.

In addition, the voice processing unit (not shown) in the control unit 370 can process the base, the treble, the volume control, and the like.

A data processing unit (not shown) in the control unit 370 can perform data processing of the demultiplexed data signal. For example, the data processing unit can decode the demultiplexed data signal even when it is coded. Here, the encoded data signal may be EPG information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel.

4 or the control unit 470 may determine the similarity of the configuration such as the shape, color, and size of the cursor, UI, etc. according to each input when the external input is connected to the digital device 200 or 300, And changes the configuration of a cursor, a UI, and the like for external input based on the result to control it to be different from a basic cursor, a UI, and the like. If the status of the digital device 200 or 300 is in the first state, the control unit 470 constructs and provides a wake-up list UI according to necessity through an application or the like in an instant boot or the like, And the second state according to the selected input mode through full boot.

Meanwhile, the control unit 370 shown in FIG. 4 may include other configurations or omit some of the illustrated configurations according to the needs of those skilled in the art, as an example of the present invention.

5 is a diagram illustrating an embodiment (s) of the control means of the digital device 500. In Fig.

As discussed above, the digital device 500 may be coupled to at least one external input (s) 551 through 55N, where N is a positive integer.

A front panel (not shown) or a control means provided on the digital device 500 is used to control the digital device 500 to which the external input (s) 551 to 55N are connected.

The control unit includes a remote controller 510, a keyboard 530, and a pointing device 520 (hereinafter referred to as a " user interface device ") implemented mainly for the control of the digital device 500, ), A touch-pad, and the like, but may also include control means dedicated to external input connected to the digital device 500. In addition, a mobile device such as a smart phone, a tablet PC, or the like which controls the digital device 500 through mode switching or the like is not included in the control means. It should be noted that the present invention is described herein with respect to a pointing device as an example, but the present invention is not limited thereto.

The control means may be a communication protocol such as Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (UDA), Ultra Wideband (UWB), ZigBee, Digital Living Network Alliance (DLNA) At least one can be employed as needed to communicate with the digital device.

The remote controller 510 is a conventional control means having various key buttons necessary for controlling the digital device 500. [

The pointing device 520 includes a gyro sensor or the like to implement a pointer corresponding to a screen of the digital device 500 based on a user's motion, The control command is transmitted. Such a pointing device 520 may be named with various names such as a magic remote controller, a magic controller, and the like.

The keyboard 530 provides a variety of services such as a web browser, an application, and a social network service (SNS) as an intelligent integrated digital device beyond the conventional digital broadcast service providing only conventional broadcasts. It is not easy, and it is implemented to complement input and realize input convenience such as text by implementing similar to PC keyboard.

The control means such as the remote control 510, the pointing device 520 and the keyboard 530 may be provided with a touch pad as required to provide more convenient and various control purposes such as text input, pointer movement, .

When the digital device 500 is connected to at least one external input, the digital device 500 can switch to a mode for providing content through an external input (hereinafter referred to as an 'external input mode'). At this time, the digital device 500 of the external input mode can use the control means dedicated to the external input, but the digital device 500 of the external input mode can be continuously operated As an example will be described. Here, the control means in use may also be required to switch the mode for transmitting / receiving the control signal in the corresponding mode in response to the switching of the external input mode of the digital device 500.

In general, when the same user switches to the external input mode while viewing the digital device, the mode switching and the current mode can be easily recognized. However, if the user temporarily leaves the room or worries about something else, It may not be recognized. Further, if a plurality of external inputs are connected to the digital device, it may not be easy to know which external input mode is activated. This is true for other users. That is, it is difficult to recognize whether the previous user uses the external input mode or the other general viewing mode in using the digital device, and it is difficult to recognize the state of the digital device, for example, a stand- A similar problem may arise even when it is turned on.

Therefore, if the user can not easily and quickly recognize the mode type or type of the digital device at present, he or she can recognize the mode accurately and control the digital device in a desired direction at a time, It can lead to complaints such as having to go through various depths.

In addition, when an external input is connected to the digital device, a UI (User Interface), a control-related key value, and the like for allowing the user to continue using the existing control means at the time of connection or switching to the external input mode May be required to be provided in the same or similar constitution. The external input or the digital device may be downloaded from the related server or the corresponding device, and compared with the existing UI or control-related key value, the same or similar form can be changed and configured. On the other hand, the external input or the digital device can automatically or manually check whether the UI or the control-related key value exists or not, according to the setting at the time of connection.

Accordingly, in this specification, a user who intends to control the digital device through the control means recognizes the state (mode) of the digital device through the control means, so that the user can control the device more quickly and easily without error, without requiring an unnecessary process .

6 is a diagram for explaining an embodiment of a process of processing an input signal of the control means in the digital device 610 in the external input mode.

The user can select or access the pointing device 620 on the digital device 610 by moving the pointing device 620 up and down and left and right to position it in a desired object or area. Accordingly, the digital device 610 may perform a predetermined function mapped to the object or the area and output the function.

If one external input 650 is connected to the digital device 610 and the content is running on the digital device 610 via the external input 650. Here, the case where the external input 650 is connected to the digital device 610 through the HDMI interface will be described as an embodiment.

The user can use the pointing device 620 to control the content of the external input 650 provided on the digital device 610. [

6, when the user moves the pointing device 620 from point 1 622 on the digital device 610 to point 2 624 in the horizontal direction (left to right), the digital device 610 is pointing At least one of the coordinates (X, Y) of the point 622 of the device and the coordinate data of the difference between the coordinates (X ', Y') of the point 624 and the coordinate value do. At this time, the generated coordinate data may include not only coordinate values but also user's request through motion or button of other pointing device 620 such as click, access, drag or the like.

The digital device 610 transfers the generated coordinate data to the external input 650 so that the user's request or control signal for the external input 650 being provided on the digital device 610 can be properly processed .

The digital device 610 is capable of delivering the generated coordinate data to the external input 650 in various forms or schemes. Coordinate data transmission can be accomplished through various methods such as a method using a CEC line of HDMI, a method using a UIBC packet wirelessly, a method using a PLC as a power line, a method using a server, and a method of receiving from a pointing device .

Here, the method of using the HDMI CEC line may be such that, for example, when the two are connected by the HDMI method, the coordinate data corresponding to the HDMI standard is generated in the digital device 610, To the input 650.

The UIBC packet using method uses a data transmitting and receiving device 630 that can be connected to both of the HDMI method and the wireless method irrespective of the connection method. For example, the data transmission / reception device 630 generates a UIBC packet including coordinate data according to a connection method with the digital device 610 and the external input 650, and transmits the UIBC packet to the digital device 610 And transfers the generated UIBC packet to the external input 650.

The method of using the power line PLC is such that the digital device 610 and / or the external input 650 functions by the power supplied through the same or different power line, and conveys the coordinate data generated through the power line . For example, it is common for a power line not to supply power only to the digital device 610, the external input 650, etc. but to have at least one data transmission / reception line (s) for data transmission / reception and to predefine the data format . Accordingly, the digital device 610 converts the generated coordinate data into coordinate data corresponding to the data transmission / reception format of the data transmission / reception line in the power line, and transmits the coordinate data to the external input 650 through the line. At this time, the digital device 610, the data transmission / reception device 630, and the external input 650 can appropriately convert the coordinate data according to the corresponding format, if necessary.

In the server utilization method, both the digital device 610 and the external input 650 can be connected to a server or a control unit of a manufacturer or a home network, and use the server. In other words, when the generated coordinate data is uploaded to the server or the control unit through the digital device 610, the coordinate data is downloaded from the external input 650 and used.

In addition, in the pointing device using method, the pointing device for the digital device 610 in the external input mode can be connected to the external device as well as the digital device 610, either wirelessly or wirelessly. That is, the generated coordinate data is transferred from the digital device 610 to the external input 650 via the pointing device 620. [ In this case, it is also possible to convert to a data format necessary for each device.

Each of the above-described methods may be used to transmit coordinate data separately between the digital device 610 and the external input 650, or a plurality of methods may be combined as needed to transmit coordinate data to further increase the accuracy, A malfunction caused by a network error or other data error can be prevented through backup to improve user convenience. However, problems such as data processing complexity, system efficiency, power consumption, and the like, which are generated when a plurality of coordinate data is transmitted, can be minimized by prioritizing each coordinate data transmitted.

The digital device 610 and the external input 650 can minimize the inconvenience of the user by continuously updating the UI and the key value etc. Such updating can be performed automatically or manually at the time of connection or mode switching have. Therefore, even if the input mode is switched, the user can use the same or similar functions without inconvenience through the same or similar UI, key.

However, the digital device 610, the external input 650, and the like can not have the same UI, key value, This is because the treatment subjects are different from each other, and the inherent limit of each one, that is, the device targets themselves are different from each other. Therefore, even if the same or similar UI is provided despite the mode switching, a function different from the user's input intention may be performed. For this reason, it is important to recognize the current mode accurately, otherwise the user will be able to recognize the current mode only after experiencing several depths through a menu or experiencing a few errors. Further, this problem may also be different depending on the state of the digital device. Here, the state of the digital device means a state in which the power is completely turned off, a stand-by state, a power-on state, and the like. For example, in the stand-by state, Is not known and it is possible to switch to the desired mode only after turning on the digital device. Therefore, mode selection and mode switching according to the mode recognition and the digital device state will be described in detail with reference to the accompanying drawings.

FIG. 7 is a view for explaining an embodiment of a mode recognition method, FIG. 8 is a view for explaining another embodiment of the mode recognition method, and FIG. 9 is a diagram Is an illustration showing an example.

The mode recognition method of FIG. 7, for example, is a method in which the shapes of cursors according to modes are implemented differently.

The digital device 710 to which at least one external input 740 is connected differently embodies the cursor shape 730 of the control means and the cursor shape (basic cursor) 720 in the case of the external input mode . Accordingly, the user can recognize the current mode directly from the appearance of the cursor appearing on the digital device 710 according to the control means.

7, for example, changing the cursor shape of the control means for mode recognition has been described as an example. However, it is also possible to change the shape of the cursor of the control means for various modes such as cursor shape, cursor size, cursor color, highlight, 2D / 3D In the normal viewing mode and external input mode, the current mode can be recognized immediately by only the cursor.

For example, unlike FIG. 7, the mode recognition method of FIG. 8 provides a UI (810 or 820) for mode recognition in a predetermined area on the screen without changing the cursor. In FIG. 8, it can be combined with the mode recognition methods 830 and 840 of FIG. That is, the mode recognition UI 810 or 820 may be provided in a predetermined area on the screen while giving a change to the cursor.

8, the mode recognition UI is provided with only one of the UI 810 indicating that the mode is the normal viewing mode and the UI 820 indicating the external input mode for the external input 850 connected to the current mode. (810 or 820) may be implemented only when the user activates the control means and disappear otherwise. Alternatively, it may be implemented such that when the user activates the control means or the state of the digital device is changed from stand-by to turn-on, it disappears for a predetermined time.

In addition, when the mode recognition UI 810 or 820 is provided, various implementations can be implemented so that the user can recognize the highlight, color, size, 2D / 3D, etc. at least once.

In addition, it is also possible to output all of the mode recognition UIs 810 and 820, to darken the UI indicating that the mode is inactivated, and to brighten only the UI indicating that the mode is the activated mode.

On the other hand, the UI indicating the external input mode is provided according to the type of the connected external input when a plurality of external inputs are connected, and provides a UI corresponding to the corresponding external input according to the type of the activated external input, Only one external input UI may be provided.

FIG. 9 is for explaining a method of processing a cursor, a mode recognition UI, and the like and a control signal corresponding thereto according to FIGS. 7 to 8. FIG.

9A, when a shortcut key such as an external input of the control means is pressed, the screen is switched and a menu item is provided as shown in FIG. 9B. In this menu item, a UI Is provided. Here, the UI may have the same function as the mode recognition UI of FIG. 8 described above.

9 (c), a process of inter-component processing is described with reference to FIGS. 6 to 9 (b). When a user's input is received through the interface 910 through the control unit, The UI for the TV 921 and the external inputs 922 to 92N (N is a positive integer) is determined according to the input of the user, and a control signal and a UI or a key value related thereto are generated and transmitted to an external input or the like do.

10 to 19 are diagrams for explaining embodiments of the mode selection method.

Hereinafter, Figs. 10 to 19 relate to a mode selection method, wherein the mode selection can be implemented differently depending on the state of the digital device. For example, in the present specification, embodiments for identifying a mode to wake-up in a case where the digital device is currently waking up in the stand-by state will be described for convenience. This is because unlike FIGS. 7 to 8, the digital device in the stand-by state is provided with the default mode or the previous mode as it is, which may not meet the user's intention or may be inconvenient, It is necessary to select which mode is woken up at the time of wake-up. When the wake-up mode is selected in this way, it is preferable that the cursor and the like are simultaneously processed as shown in Figs. 7 to 9 described above.

Fig. 10 shows a UI 1020 provided when the user wishes to wake up the digital device via the control means in a stand-by state.

The wake-up UI 1020 is provided with a list of at least one external input mode 1040, 1050 (external input 1 to external input N) coupled with a general viewing mode (TV) Thus, when the user selects any one of the lists through the cursor 1010 according to the control means, the digital device wakes up in the selected mode.

Here, in providing the wake-up UI 1020, the digital device can provide a mode selection convenience by providing a mode set to a default mode or a mode immediately before a standby mode differently from other mode icons so as to identify the modes have.

The wake-up UI 1120 of FIG. 11 is similar to that of FIG. 10, but illustrates icons 1120, 1130 through 1150 of a form that can more easily identify a mode icon rather than text. In this case, when the cursor 1110 is positioned at the lower end of each icon, basic information such as the name of the content, the degree of reproduction, and the like can be also output.

FIG. 12 shows a state in which the cursor 1205 is initially output according to the movement of the control means, or input modes of a predetermined shape are provided in a screen predetermined region (for example, the screen center) in order to select an input mode to be woken up in a similar manner / RTI > For example, a left arrow shape 1210 indicates a TV, an upper arrow shape 1220 indicates an external input 1, a right arrow shape 1230 indicates an external input 2, and a lower arrow shape 1240 indicates an external input 3 It can mean.

Therefore, when the user accesses the cursor by placing the cursor in any one of the arrow shapes, it wakes up in the stand-by state in the corresponding input mode.

In FIG. 12, four icons are shown according to four external inputs. However, the present invention is not limited to this, but may be provided according to the number of connected external inputs or may be all provided but partially disabled or not selectable.

Referring to FIG. 13, a wake-up UI is configured so that one of the TV / external inputs 1320/1330 can be selected at the edge of the screen.

If the user wants to wake up in another input mode, the center window (external input 1) 1420 can be selected through the arrow icons 1430 and 1440 Do. It is obvious that the present invention can be implemented in various forms such as a left / right direction as well as a vertical direction. In addition, the digital device may be configured to allow the user to select an input mode via the left / right direction icons 1430 and 1440, or to provide an input mode window 1420 or a wake-up list UI of the screen to wake- When the cursor 1410 is accessed in an area other than the area, the wake-up operation is directly performed in the corresponding mode.

15 to 16, a wake-up list UI (1520, 1530, 1620, 1630) is provided at the edge of the digital device screen.

Here, the wake-up list UI positioned at the upper, lower, left, and right sides may be provided at a predetermined wake-up request, or may be provided with a UI closest to the position of the cursor 1510 or 1610 to be initially activated.

In this case, the wake-up list UIs 1520, 1530, 1620, and 1630 display the immediate input mode through the input mode selection windows 1522, 1532, 1622, and 1632, and when the cursors 1510 and 1610 are positioned, A list of input modes may be provided. In addition, the wake-up list UIs 1520, 1530, 1620, and 1630 may include information windows 1524, 1534, 1624, and 1634 for the content being provided in the previous mode together with the input mode selection windows 1522, 1532, 1622, Can also be provided. For example, in the information windows 1524, 1534, 1624, and 1634, information on a type of an input mode, a content type, a content name, a content attribute, a 2D / 3D status, a current playback level, a codec information, / RTI > Also, although not shown, when cursors 1510 and 1610 are positioned in the information windows 1524, 1534, 1624, and 1634 in the case of a short moving picture or thumbnail information, an EPG, a channel browser, Or may be provided in a pop-up form in a predetermined area on the screen separately. When the cursors 1510 and 1610 are positioned in at least one of the input mode selection windows 1522, 1532, 1622 and 1632 and the information windows 1524, 1534, 1624 and 1634, The window is enlarged to a predetermined area of the screen in the direction of an arrow on the UIs 1520, 1530, 1620, and 1630, and an input mode selection list and detailed information are provided.

Accordingly, the user can control not only the selection of the input mode at the time of wake-up but also the desired information about the content or the like to be immediately accessed or output, so that a separate control operation can be performed in advance after the screen is loaded for wake-up have.

17, rectangular input mode list windows 1720 to 1760 are unfolded and each window is activated and highlighted according to the movement of the cursor 1710. When selected, the other windows disappear and are woken up and the contents of the corresponding mode A window for the selected mode is continuously provided until the user is informed of the selected mode.

In this case, if the selected input mode window is again accessed from the input mode list windows 1720 to 1760, that is, the wake-up process is temporarily stopped and the other input that has disappeared for switching to another mode The windows of the mode can be provided again.

Referring to FIG. 18, when the user makes a wake-up request, the digital device provides the input mode selection window 1830 in a pop-up form at the lower right or around the cursor 1810.

Accordingly, a desired input mode can be selected through the window 1830 as described above.

Meanwhile, in the case of FIG. 19, for example, it is possible to change the shape of the icon according to activation / deactivation of the corresponding mode to identify whether the activation / deactivation is performed. For example, when the icon of the external input 1 on the upper right side is inactivated as in the form of the first icon 1930-1, the cursor 1910 indicates that the dark color and the dotted line, Or if it is selected, it is changed to a bright color, a solid line, a bright expression or the like so as to indicate that it is activated, so that the input mode can be identified with a fun to the user.

In this case, the selected icon is continuously provided in the wake-up process and may finally provide the user with the remaining time until wake-up.

In addition, in the above description, if necessary, various information can be provided between the last wake up in the process of wake-up, that is, in the input mode selection. For example, if it takes a certain period of time until final wake-up for various reasons, the user may be informed of the content of the selected mode or the summary information of the immediately preceding playback content, It is possible to minimize the inconvenience caused by the wake-up time period by providing frequently viewed advertisements or contents.

Such an icon may vary not only when the input mode is selected at the wake-up in the stand-by state but also when the external input mode is selected or switched, such as when the external input key of Fig. 9 (a) Lt; / RTI >

When the user selects an area other than the area provided with the wake-up UI via the control means, presses a key button not related to the wake-up mode selection, or selects an icon in the default or immediate mode, Wake-up can be performed.

The above-described Figs. 10 to 19 are not only used only for mode selection, but are also available for all recognition with or in addition to Figs. 7 to 8. Fig.
