  • The user interface unit 290 delivers a signal input by a user to the control unit 250 or may transmit a signal delivered from the control unit 250 to the external device (e.g., the remote controller 300, the mobile device 150, etc.). The user interface unit 290 receives a control signal for power-on/off, channel selection, screen setup or the like from the remote controller 300 and then processes the received control signal, in accordance with various communication systems including the RF communication system, infrared (IR) communication system and the like. Alternatively, the user interface unit 290 can transmit the control signal delivered from the control unit 250 to the remote controller 300 or the mobile device 150.
  • In addition, the video output unit 260 generates a drive signal by converting a video signal, a data signal and an OSD (on screen display) signal, which were processed by the control unit 250, or a video signal, a data signal and the like, which are received from the external interface unit 230, to R, G and B signals. The audio output unit 270 receives an input of an audio signal (e.g., stereo signal, 3.1 channel signal, 5.1 channel signal, etc.) processed by the control unit 250 and then outputs the received signal.
  • Further, the power supply unit 280 can supply a corresponding power to each of the components that configure the main device 100. The power supply unit 280 can supply power to the control unit 250 implemented into SOC (system on chip), the video output unit 260 for a video display, the audio output unit 270 for an audio output and the like. Further, the control unit 250 is described in detail with reference to FIG. 3 and FIG. 4 as follows. In particular, the control unit shown in FIG. 3 may include individual components or can be implemented into a single module.
  • Next, FIG. 3 is a block diagram illustrating one example of a control unit 350 of the main device 100 or the mobile device 150 according to an embodiment of the present invention. In particular, as mentioned in the foregoing description with reference to FIG. 2, the control unit 350 in FIG. 3 may correspond to a component of the main device 100 or the mobile device 150 shown in FIG. 1.
  • Referring to FIG. 3, the control unit 350 includes a demultiplexer 351, a video decoder 352, a scaler 353, an OSD generator 357, a mixer 354, a frame rate converter (FRC) 355 and a formatter 356. Moreover, the control unit 350 may further include an audio processor, a data processor and the like.
  • In addition, the demultiplexer 351 demultiplexes an input transport stream, and the video decoder 352 decodes a demultiplexed video signal. Further, the scaler 353 performs scaling to enable a resolution of the decoded video signal to be outputtable from the video output unit.
  • The OSD generator 357 generates OSD data in response to a user input or by itself. Further, the mixer 354 mixes the OSD data generated by the OSD generator 357 with the video signal processed by a video processor including the video decoder 352 and the scaler 353. The frame rate converter (FRC) 355 can convert a frame rate of an input video. In this instance, the video frame rate conversion may be attributed to an output frequency of a display module. For instance, the frame rate converter 355 converts a frame rate 60 Hz of an input video to a frame rate 120 Hz or 240 Hz of a video output to correspond to an output frequency of the display module.
  • The formatter 356 receives an input of an output signal of the FRC 355, changes a format of the received signal to be suitable for the video output unit, and then outputs the format-changed signal. For instance, the formatter 356 can R, G and B data signals. In addition, the R, G and B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.
  • The components described with reference to FIG. 2 and FIG. 3 may be merged together into a module or may be implemented as individual components. In addition, prescribed components may be omitted or added. Moreover, input signals or data may bypass prescribed components in response to various kinds of inputs.
  • The present invention provides an environment to facilitate data transmission and receptions (control data or signals included) between a mobile device and a main device more efficiently and also provides an interface for the environment. In this specification, various digital device objects including a mobile device, a main device, an external device and the like are described. In particular, regarding a mini TV, a mobile device may be taken as an example. However, the spirit or scope of the inventions in association with the mini TV is not limited to the mobile device only.
  • Further, in order to help the understanding of the present invention and provide convenience in description, a mobile device can access a mini TV via various paths and depths. For instance, the mini TV may be activated in response to an activation of a remote application. Further, the present invention provides a service processing apparatus for providing a communication environment or interface with further enhanced functions to overcome a limited function of a mobile device playing a role as a display device capable of simply outputting data or signals received from a main device (e.g., providing the same screen of the main device) or a limited function of the mobile device used as a substitute for an input means of a main device like a remote controller. The present invention also encourages a user's purchase desire by providing a user-friendly interface environment and/or service.
  • Next, FIG. 4 and FIG. 5 are diagrams illustrating a process for pairing a mobile device and a main device with each other according to an embodiment of the present invention. Referring to FIG. 4 and FIG. 5, a user interface (UI) provided in association with a paring and the like may slightly differ in accordance with a type of a mobile device (e.g., a smart phone shown in FIG. 4 or a tablet PC shown in FIG. 5).
  • First of all, a mobile device activates a remote application (S102, S202). Thus, when the mobile device activates the remote application, a pairing process starts. The paring may be performed on a previously agreed or defaulted device such as a main device or every device linkable or interoperable with the mobile device via wire/wireless network. Hence, the mobile device provides a list of all paired devices to a mobile terminal and can then be paired with a device having a best network condition or a best communication status for the pairing, a device according to a preset priority or the like, for example.
  • Further, if the remote application is activated, a state of the pairing is determined or the pairing is started, for example. However, if the pairing is determined in accordance with an attribute of an activated application instead of the remote application, the pairing process may be performed. Moreover, the pairing may be initiated in response to a user's setup or under a prescribed condition irrespective of the activation of an application. However, the pairing process is assumed to be performed in response to the activation of the remote application.
  • Once the remote application is activated, the mobile device determines a communication network state for the pairing, i.e., a presence or non-presence of a connection with a network or a connected state with the network (S104, S204). For this, the mobile device can provide a UI 410/510 indicating that a network connected state is being checked. In FIG. 4 or FIG. 5, the communication network for the pairing includes Wi-Fi, for example, by which the present invention is non-limited. Alternatively, the communication network may include Ethernet terminal for a connection with the wire network or such a communication protocol for a connection with the wireless network as WLAN (Wi-Fi), Wibro, Wimax, HSDPA and the like.
  • In the step S104 or S204, as a result of the determination of a presence or non-presence of the connection with the network or the connected state for the pairing, if the connection is not established, a popup indication is displayed on a screen of the mobile device (S106, S206). When the network is not connected, it may be because a user randomly blocks the network connection or the network connected state is poor due to a location of the mobile device and/or the like. Therefore, if the user of the mobile device checks the pop-up indication in the step S106 or S206, the user can solve this problem by setting up a network connection, moving the location or the like. Thus, the mobile device can provide the screen with the UI 410/510 to indicate that the connected state is being checked. In particular, the UI 410/510 can be provided if the user does not block the network connection in the mobile device.
  • Subsequently, the method checks how many devices are connected with the network through the step S104/S204 or the step S106/S206 (S108, S208). Through this checking step, if the number of the connected device(s) is 0, for example, a UI 420/520 is provided to indicate that there is no connected device. The user may reattempt the above-described process by resetting the network or setting another network.
  • On the other hand, if the number of the device(s) connected to the network is checked as 1 or more in the step S108 or S208, the mobile device provides a UI 430/530 including information on each connected device (e.g., only 1 device is displayed in this example) and determines whether a history of a previous connection with the corresponding device exists (S110, S210). If the previously connected history exists, the mobile device obtains a status of the corresponding device and then checks whether the corresponding device is connectible (S112. S212). If the corresponding device is not in the connectible status currently, the mobile device provides a guide UI 440/540 for the solution (S114, S214).
  • Further, if the number of the devices connected to the network, which is checked in the steps S108 or S208 is equal to or greater than 2, the mobile terminal provides a UI 430/530 including information on each of the connected devices and then waits for a selection made by a user. If the user selects a prescribed device through the UI 430/530, the mobile device checks a status of the selected device and then determines a connectible state (S116, S216). Thus, the UI 430/530 can provide various kinds of information including an identifier, name, power-on/off state, connectible state and network connected state (e.g., signal strength, etc.) of each of the devices and the like.
  • As a result of the determining step S116 or S216, if the corresponding device is not in the connectible state, the mobile device can provide the UI 440/550 indicating a guide to the solution. If the corresponding device connectible state is enabled via the guide or the connectible state of the corresponding device is determined in the step S116 or S216, the mobile device determines whether a history of a previous connection with the corresponding device exists (S118, S218).
  • If the state connectible with the corresponding device is enabled through the step S112/212 or the step S114/214, the mobile device may complete the pairing process. In addition, the mobile device provides a UI 450/550 for a next operation to be performed together with the paired device. Further, if the history of the previous connection with the corresponding device exists (Yes in S118, S218), the mobile device ends the pairing process and then provides the UI 450/550 to enable a next process to be performed. On the contrary, if the history of the previous connection with the corresponding device does not exist (No in S118, S218), the mobile device undergoes the step for an access to the corresponding device to complete the pairing process with the corresponding device.
  • In this step, the mobile device provides a related UI 460/560. In FIG. 4 and FIG. 5, a security related UI such as a user authentication window is exemplarily shown, by which the present invention is non-limited. In addition, other UIs for the corresponding step can be further provided. Further, if there is no connection history in the step S110 or S210, the UI 430/530 or the UI 460/560 may be provided.
  • The above description of the present invention with reference to FIG. 4 and FIG. 5 describe one embodiment of a pairing process between a mobile device and another device assuming that the pairing is performed by paring a mobile device and a main device (e.g., a main TV) with each other. The pairing can be performed on other external devices. In this instance, both of the foregoing description and the following description may be applicable to the pairing in a similar manner.
  • In the following description, for example, of a mini TV function activation between a mobile device (e.g., a mini TV) and a main device (e.g., a main TV) paired with each other according to an embodiment of the present invention, various methods for exchanging data with the main TV are explained.
  • In particular, FIGS. 6 to 12 are diagrams illustrating a method of providing a mini TV function in a mobile device after pairing according to embodiments of the present invention. That is, FIGS. 6 to 12 show examples of mini TV providable scenes of a mobile device in accordance with a state or mode of the mobile device and/or a main device.
  • FIG. 6 is a diagram illustrating one example of a scene for a mobile device to provide a mini TV when watching a normal screen in a main device. Referring to FIG. 6, a main TV 610 initially displays DTV channel 6. If the main TV 610 is paired with a mobile device 620 by the pairing process mentioned above, the mobile device 620 exchanges data with a main device (main TV 610), thereby providing a mini TV function.
  • For instance, if the pairing and the mini TV function are initiated by activating the remote application, the mobile device 620 provides a channel (or content) currently provided by the main device 610 to a screen for the mini TV function. This process may continue until a channel switching operation is performed by the paired main device 610 or the mini TV function is turned off, for example.
  • If the channel is switched or changed (e.g., channel 6 to channel 7) in the main device 610, the channel of the mini TV 620 is switched or changed to the same channel. However, although the mobile device can directly switch the channel in response to the main device, the mobile device can also inform a user using a popup UI indicating whether the channel is switched to another channel (e.g., channel 7) in the main device 610, whether a channel is changed, and/or the like and may then enable the channel switching operation to be performed in response to a selection made by the user.
  • Thereafter, if the channel is switched to another channel (e.g., channel 8 from channel 7) again in the main device 610, the mobile device 620 may perform an automatic channel switching operation or a channel switching operation in response to a user selection after providing a UI. Thus, the operation of the mini TV 620 in response to the channel change or switching of the main TV 610 is described with reference to FIG. 6, for example.
  • Next, FIG. 7 is a diagram illustrating one example of a scene for a mobile device to provide a mini TV when changing an input while watching a broadcast screen in the main device 610. Referring to FIG. 7, the main TV 610 initially provides DTV channel 6. If the mobile device 620 is paired with the main TV 610 by the paring process described with reference to FIG. 4 or FIG. 5, the mobile device 620 exchanges data with the main device 610 by being linked with the main device 610 and then provides a mini TV function.
  • The mobile device 620 provides the DTV channel 6 currently provided by the main TV 610. This may continue until a channel change or switching occurs in the main TV 610, for example. If an input to the main TV 610 is changed (e.g., the input is changed into a component input instead of a DTV channel for watching a broadcast program), the mini TV 620 of the mobile device may perform two kinds of operations as follows. First of all, the mini TV 620 performs an operation of changing a screen of the mini TV 620 in response to an input change of the main TV 610. Secondly, the mini TV 620 can perform an operation of maintaining a current screen of the mini TV 620 despite that the input of the main TV 610 is changed.
  • In the former case, if the mini TV 620 has a configuration corresponding to a component input, for example, it can play back the component input. If the mini TV 620 does not have the corresponding configuration, a format of data received from the main TV 610 may be converted to a format (e.g., file conversion, resolution conversion, size adjustment, screen ratio adjustment, etc.) that is outputtable from the mini TV 620.
  • Next, FIG. 7 shows the latter case. In particular, the mini TV 620 provides a screen by tuning a channel for a current screen by itself. Alternatively, the mini TV 620 receives a signal from the main TV 610 and then plays the received signal. Referring to FIG. 7, when an input to the mini TV 620 is changed into such an external input as a component, the mini TV 620 can keep providing a previous channel irrespective of the input change unless a channel for a broadcast program is switched in the main TV 610. In particular, in FIG. 7, the mini TV 620 continues to provide the DTV channel 6 at the timing point of changing the input of the main TV 610 to the component input.
  • Thus, the mini TV 620 can switch a channel (e.g., channel 6 to channel 7) separately from the external input of the main TV 610. However, since the main TV 610 still provides the data according to the component input, the main TV 610 does not provide the channel 7. On the other hand, if the input of the main TV 610 is switched from the component input to a broadcast channel for a broadcast program, the main TV 610 may perform the following operations. First of all, the main TV 610 changes a channel previously provided before the external input switching into the same channel currently provided by the mini TV 620 and then provides the same channel currently provided by the mini TV 620. Secondly, the main TV 610 continues to provide the channel previously provided before the external input switching.
  • For instance, FIG. 7 shows the former case of providing the channel currently provided by the channel previously provided before the external input switching. If the mini TV 620 receives and plays a broadcast signal using the tuner of the main TV 610, since the main TV 610 is already tuned to the corresponding channel for a channel switching operation of the mini TV 620, it may have no difficulty in providing a screen as soon as the input switching is performed. However, if the main TV 610 has a plurality of tuners or the tuner of the main TV 610 is used for the channel switching operation in the mini TV 620, the main TV 610 can operate like the latter case. Moreover, even if the main TV 610 has a single tuner, the main TV 610 can provide the channel 6 again by being forced to be tuned to the previous channel.
  • In the above description, the examples of the operations of the mini TV in response to an input change or switching of the main TV are explained with reference to FIG. 7.
  • Next, FIG. 8 is a diagram illustrating one example of operations when changing an input while the mobile device 620 is providing a broadcast program on a channel received from the main device 610. In particular, FIG. 8 shows an operation for a case opposite to that shown in FIG. 7. For instance, FIG. 8 relates to operations of a mobile device and a main device when an input of the mini TV 620 is switched to a component input despite that the main TV 610 keeps displaying the broadcast program, whereas FIG. 7 shows that the main TV 610 changes a currently watched broadcast program into a component input.
  • If the main TV 610 provides the DTV channel 6, the mini TV 620 also provides the same DTV channel 6 by processing a signal received via the main TV 610. Thereafter, despite that there is no change in the main TV 610, an input of the mini TV 620 is switched to a component input. The input of the main TV 610 is switched to the component input by being linked with the mini TV 620 or no change may occur in the main TV 610. FIG. 8 shows one example of the latter case. In particular, the main TV 610 continues to provide the same channel after the component input switching of the mini TV 620.
  • Subsequently, the main TV 610 can change a broadcast channel irrespective of the mini TV 620. In this instance, the mini TV 620 continues to maintain a currently provided external input or may provide a changed channel, in response to a broadcast channel change of the main TV 610. Further, the main TV 610 and/or the mini TV 620 provides a popup alarm for changed items of each device as a result of a mini TV function activation or a pairing and can then perform a corresponding operation. Further, although the pairing is provided to perform the mini TV function, it may be performed irrespective of the mini TV 620.
  • In FIG. 8, the mini TV 620 continues to provide the component input irrespective of the channel switching operation of the main TV 610. Thereafter, after the component input has been ended, if the input of the mini TV 620 is changed into a broadcast channel again, the mini TV 620 provides the previously provided channel 6 or the currently provided channel (e.g., channel 7) of the main TV 610.
  • In the above description, examples of the operations of the mobile device and the main device in response to the input switching of the mini TV 620 are explained with reference to FIG. 8.
  • Next, FIG. 9 is a diagram illustrating one example of an operation of the mobile device 620 while the main device 610 provides a component input instead of a broadcast channel. For instance, in the description with reference to FIG. 7, when the input of the main TV 610 is switched to a component input from a broadcast channel, the mini TV 620 continues to provide the broadcast channel instead of switching to provide the component input. However, FIG. 9 relates to an operation when the main TV 610 is providing the component input instead of the broadcast channel when activating the mini TV function.
  • Referring to FIG. 9, if the main TV 610 provides a component input instead of a broadcast channel, the mini TV 620 receives the component input and then provides the received component input. However, since the mini TV 620 differs from the main TV 610 in operations, attributes, capabilities and the like, the mini TV 620 converts the component input to be suitable for the mini TV 620 and then provides the converted component input. If the broadcast channel is input instead of the component input, it may be converted appropriately likewise.
  • FIG. 10 is a diagram illustrating one example of an operation of the mobile device 620 when the main device 610 switches an initially provided broadcast channel to a PC input while providing the initial broadcast channel. Although the component input is taken as an example of an external input in FIGS. 7 to 9, a PC input is taken as an example of an external input in FIG. 10.
  • Referring to FIG. 10, the main TV 610 initially provides DTV channel 6. Hence, the mini TV 620 also provides the DTV channel 6 via a screen. If an input of the main TV 610 is switched from a broadcast channel to an external input, i.e., to a PC input, the mini TV 620 may continue to maintain a previous channel or may provide the PC input. However, in the latter case, the PC input may be provided with a corresponding configuration in order to be provided by the mini TV 620 or may need a configuration to convert an input. Thus, FIG. 10 shows one example of when the mini TV 620 continues to provide the broadcast channel (e.g., channel 6) despite the PC input switching of the main TV 610.
  • Next, FIG. 11 and FIG. 12 are diagrams illustrating examples of an operation of the mini TV 620 when implementing a web browser in the main TV 610. First of all, in order to provide a mini TV function together with an activation of a remote application and a pairing process, the mini TV 620 can receive various kinds of additional information including a currently provided screen of the main TV 610, attributes, channel number, channel name, signaling information and the like. Since the main TV 610 and the mini TV 620 differ from each other in functions, attributes and the like, the additional information are received to provide an appropriate screen. Thus, various kinds of information can be transmitted and received between the main TV 610 and the mini TV 620.
  • Next, FIG. 11 shows one example of when the mini TV 620 is unable to provide a screen identical to a web browser screen of the main TV 610. Referring to FIG. 11, the mini TV 620 can display a popup alarm to indicate that a web browser is currently active in the main TV 610 and is unable to be activated in the mini TV 620.
  • Referring to FIG. 12, if the main TV 610 activates a web browser when providing a broadcast channel of an initial DTV channel 6 before the activation of the web browser, a tuner of the main TV 610 continues to provide a currently tuned broadcast channel and a popup may be provided to indicate that the activation of the web browser is impossible. FIG. 12 may be identically applicable to when the web browser is active in the main TV 610 at the time of the mini TV activation except when the main TV 610 activates the web browser in the middle of providing a broadcast channel at the time of activating the function of the mini TV 620.
  • Unlike the above descriptions mentioned with reference to FIG. 11 and FIG. 12, if the main TV 610 receives a mini TV function request, the main TV 610 can provide the mini TV 620 with address information of a currently provided web browser. In this instance, the mini TV 620 indicates that the web browser is currently active in the main TV 610 and that the mini TV function is not executable and provides a UI to determine whether the mini TV 620 will activate a web browser for a corresponding address access based on the address information provided via the main TV 610, in response to a mini TV function request made by a user. If the user selects to activate the web browser, the mini TV 620 can provide a webpage optimized for the mini TV 620 via the activated web browser.
  • In the above description, the operations of the mini TV 620 when the web browser is currently active in the main TV 610 are explained with reference to FIG. 11 and FIG. 12. In the foregoing descriptions with reference to FIGS. 6 to 12, various scenarios of operations between the mini TV 620 and the main TV 610 in accordance with the activation of the mini TV function are explained.
  • In the following description, various uses and operation scenarios for a mini TV access such as an activation of a mini TV function and the like will be explained in detail with reference to the accompanying drawings. In particular, FIGS. 13 to 15 are diagrams illustrating examples of a mini TV function access method according to embodiments of the present invention. In particular, FIG. 13 is a diagram illustrating one example of activating a mini TV function by activating a channel selected from a home screen of a mobile device.
  • For example, FIG. 13(a) shows one example of a home screen of a mobile device. Referring to FIG. 13(a), a mode of a mobile device, a network state, a remaining battery level, a signal strength, time information and the like are provided to a top end 1310 of a screen. In addition, a menu icon may be provided directly below the top end 1310 of the screen.
  • A channel list 1320 may be provided to a middle part of the screen. In this instance, the channel list 1320 is displayed and another menu screen may be provided thereto. Further, text information (e.g., “channels”) indicating that the corresponding menu is the channel list is provided to a top end of the channel list 1320 and information on a plurality of channels is provided below the text information. In this instance, the information on the channel may include broadcast station information, channel information, thumbnail image, information on broadcast time, other text information and the like for example.
  • Further, the channel list menu screen configuration shown in FIG. 13 is just exemplary. In addition, various kinds of channel list menu screen configurations can be provided in accordance with various references including broadcasting system provider, channel, viewing restriction and the like.
  • An icon including text information for an activation of a mini TV function of the present invention, image information and the like is provided to a region 1330 below the channel list. In addition, a menu item for a volume adjustment, a menu item for a channel adjustment and the like may be provided to a most bottom end 1340 of the screen. If a user performs a click, double click, pointing or the like on a mini TV icon, the mobile device directly activates the mini TV function, receives a screen currently provided by the main device, and then switches its screen to the screen shown in FIG. 13(b).
  • Referring to FIG. 13(b), the mobile device enlarges and outputs a thumbnail image 1360 of the channel which is received when receiving video data from the main device or currently provided by the main device. In addition, the mobile device can output a loading wheel animation 1365 to indicate that a loading for the mini TV function activation is in progress. Further, if an external input is currently executed in the main device, the mobile device can display an external input control panel 370.
  • Further, in the mini TV function loading process, referring to FIG. 13(b), prescribed function items including an exit item (EXIT), a TV AV on/off item (TV AV ON/OFF), a sound only item (Sound only), a capture item (Capture), an SNS (social network service) item (SNS) and the like are output to a first region 1350 of a screen. A playback bar (e.g., a reproducing bar, a replay bar, etc.) including time information of a currently corresponding content is also provided to a second region 1355 of the screen. In particular, the playback bar provides information on a current play time.
  • In addition, a control panel 1370 including channel information, broadcast station information, content information, input information (e.g., external input, TV input, PC input, etc.) 1372, a volume and/or channel adjustment item 1374 and a channel list icon 1376 is provided to a third region of the screen of the mobile device.
  • The exit item (EXIT) mentioned in the above description is provided to end a mini TV and to enter the home screen shown in FIG. 13(a). The TV AV on/off item is provided to turn on/off a display of the main TV paired with the mini TV, i.e., a power and to enable/disable a mute. If the sound only item is enabled, multitasking is implemented by keep providing a sound of a currently provided content (i.e., the sound keeps being provided despite the switching to the home screen) despite that the mini TV function is ended. On the contrary, if the sound only item is disabled, the sound of the content is not provided by being turned off together with the mini TV function. The capture item is provided to capture a current video screen and to save the captured video screen in a prescribed location. The SNS item is provided to enable a current screen to provide a screen panel related to an SNS service. In doing so, a currently provided screen is paused or may continue to be provided irrespectively.
  • The external input control item within the control panel 1370 provides a list of inputtable external inputs of each of the mini TV and the main TV and also provides a UI for a switching or change to an item selected from the provided list. Further, in FIG. 13(a), the mini TV function may be directly entered and provided in response to a prescribed action. However, a UI is configured and provided to determine what function will be activated. In addition, a selection can be made using the configured UI. For instance, the mobile device provides a UI including an icon for a mini TV, an icon for TV account login, an icon for a search, an icon for configuration settings and the like. If a user selects the mini TV icon, the mobile device may operate as shown in FIG. 13(b).
  • Another example of a method of activating a mini TV function in a home screen (or a channel list) is to drag & drop a thumbnail image of a desired channel in the channel list in direction of the item 1330 indicating the mini TV function. In this instance, unlike the foregoing description, a content of a channel corresponding to the thumbnail image selected (i.e., dragged & dropped) irrespective of a channel currently provided by the main TV. Further, if the mobile device has a configuration (e.g., a tuner) capable of tuning and receiving a broadcast signal, the screen of the main TV is not switched or changed.
  • However, if the mobile device receives a broadcast signal on a channel tuned via the tuner of the main TV, the mobile device transmits a control signal for channel information and the like to the main device and can then receive a broadcast signal from the main device in a manner that the main device receives the broadcast signal by tuning a channel based on the corresponding channel information via the tuner. Besides, if the main device includes a multi-tuner, there is no concern. However, if the main device includes a single tuner, a screen of the main TV can be provided by being switched based on the control signal of the mobile device.
  • Next, FIG. 14 is a diagram illustrating the mini TV function activation mentioned in the above description. Referring to FIG. 14(a), a channel list, which is one of a home screen shown in FIG. 13(a), is provided to a screen. Thumbnail images for a total of 9 channels are provided to the screen at a time. If a user intends to watch a mini TV by accessing a channel corresponding to the thumbnail image at the center of the 9 thumbnail images, the user touches & drags the corresponding thumbnail image item 1410/1420 shown in FIG. 14(a)/FIG. 14(b) and then drops the corresponding thumbnail image item toward a bottom direction. If so, the screen automatically collects the information on the dragged & dropped thumbnail image. A control signal is created based on the collected information and is then transmitted to the main TV. Having received the control signal, the main TV performs an operation based on the received control signal. Thereafter, the mobile device receives a signal from the main device and then provides such a screen as shown in FIG. 14(c). If the channel corresponding to the dragged & dropped thumbnail image (i.e., the selected thumbnail image) is not the ongoing channel already provided by the main TV, it may take a little bit more loading time. Further, the screen of the main TV may be switched and provided.
  • Next, FIG. 15 is a diagram illustrating one example of an access method for a mini TV function activation according to an embodiment of the present invention. Referring to FIG. 15(a), ‘any screen’ is displayed on a main screen 1510 of a mobile device. If a user performs a touch action (e.g., click, double click, press for prescribed duration, etc.) on a prescribed region of the main screen 1510 or an option icon provided to a bottom end of the main screen, an option menu function item 1520 shown in FIG. 15(b) is provided.
  • In the option menu function item 1520, an icon for a mini TV function, an icon for TV account login, an icon for search, an icon for configuration setting and the like may be included. Further, the option menu function item 1520 shown in FIG. 15(b) can be activated in response to a prescribed action (e.g., shaking the mobile device right and left, shaking the mobile device up and down, etc.) as well as the above touch action. The mobile device may further include a gyro sensor and the like.

The optional function icons 2554 may be provided with a power key and keys for controlling channels, media, directions, touches, games and the like. For instance, if the touch key is selected, a whole screen turns into a touchpad to play a role as an input means for inputting a control command and the like to a main TV and the like.
  • The channel list in the premium menu shown in FIG. 25(a) may include an identifier (ID) (or, a name) for identifying a channel list for example and may be provided with a preview item, a detailed program information item 2544, and a channel list item. Moreover, a function icon 2560 for changing a configuration or arrangement system of channel list items is provided to a prescribed region of the screen.
  • In particular, the preview item may be provided with a mini TV function icon 2542 together with a still image such as a thumbnail image or a video. Hence, it can directly activate a mini TV function from the preview item in the course of a channel list access according to an embodiment of the present invention. If the mini TV activating icon 2542 is selected from the preview item by a user, the mobile device receives a channel or content corresponding to the preview item from a corresponding device and then provides the received channel or content (FIG. 25(b)). In this instance, the device is non-limited by a main TV. Alternatively, the device may include one of various devices including an external input and the like. However, an indication for a corresponding input can be displayed. Further, the device may include an individual or separate content provider (CP) or IP server.
  • If the function icon 2560 is selected, it pops up to provide type information on various configuration or arrangement systems. If one of the type information is selected, the screen configuration shown in FIG. 25(a) may be changed overall.
  • For instance, referring to FIG. 26(a) and FIG. 26(b), when a plurality of contents are provided in horizontal direction, a screen related to a content at the screen center has a largest size and a size ratio of a screen may relatively decrease toward an edge of the screen. Referring to FIG. 26(a), a function icon for volume adjustment and a function icon for enabling a channel list to pop up are provided below the contents. In particular, the popup function icon can be provided at the center below the contents. Referring to FIG. 26(b), a channel list is enumerated in horizontal direction to provide schematic channel numbers and names.
  • Further, referring to FIG. 26(a) and FIG. 26(b), each channel or content list may provide a preview image 2610 together with channel or content information. In addition, time information such as a current play time, a remaining play time and the like may be displayed as a play bar below the preview image. Further, the preview image 2610 may include a still image such as a thumbnail image or a moving picture. In addition, a mini TV switching icon 2620 may be further included within the preview image 2610.

  • According to an embodiment of the present invention, if the mini TV switching icon 2620 within the preview image is selected in the course of the service shown in FIG. 26(a) or FIG. 26(b), it can directly provide a mini TV switching screen shown in FIG. 25(b). Further, if the mini TV switching icon 2620 is not provided within the preview image, a preview image is selected and then dragged & dropped in prescribed direction, whereby the mini TV function can be entered.
  • Next, FIG. 27(a) shows one example of a screen provided with both a channel browser and EPG information. FIG. 27(b) and FIG. 27(c) show one example of a screen of a channel browser provided with a list and detailed information. The overall contents of FIG. 27 are similar to those of FIG. 25 and FIG. 26 but differ from the contents of FIG. 25 and FIG. 26 in the formats provided for the channel browser and EPG. In this instance, a user just performs a flicking operation to search or move right and left channels and EPG information of a corresponding channel in a vertical direction. Using the EPG information, it can perform such a function as recording/recording reservation and the like. Further, the channel provided at the center within the channel browser may be switched to a mini TV by dragging & dropping a mini TV switching icon or image inside in prescribed direction, as mentioned in the foregoing description with reference to FIG. 26(a) and FIG. 26(b). In addition, a function item ‘real-time use’ may be usable in providing a preferred function.
  • FIG. 27(b) and FIG. 27(c) have contents similar to each other overall but slightly differ from each other in a display format. Referring to FIG. 27(b), a channel provided to a center region of a screen is provided with a detailed content only but schematic information is provided to the remaining region. Referring to FIG. 27(c), a channel provided to a top end of a screen is provided with a detailed content only but channels in the rest of the regions below are provided with schematic information only. Further, in FIG. 27(b) or FIG. 27(c), a mini TV switching icon within a preview image or the preview image is dragged & dropped in prescribed direction, thereby entering a mini TV directly.
  • Further, in this specification, a time machine function is explained by taking a content (e.g., a video, a moving picture file) as an example. Moreover, the time machine function is applicable to a still image file such as an image, an audio file such as music, a text file and the like in a similar manner. In addition, a UI may be configured in a similar manner in consideration of a content attribute, a step of a user interface and the like.
  • FIG. 28 is a diagram illustrating one example of a method of providing a time machine function in a mobile device. Referring to FIG. 28, a mobile device provides a content to a screen. The provided content may include one of mini TV functions of outputting a video received from a main TV.
  • In consideration of features or attributes of a mobile device, a time machine function may be activated automatically or manually in one of the following cases. A user can randomly stop a content currently played in a mobile device. The mobile device may operate as follows. First, the mobile device stops playing a content in response to a request made by a user and does not perform other operations.
  • Secondly, the mobile device stops playing a content after the timing point of requesting to stop a time machine function and provides a time machine UI. The latter case may be performed only if a separate time machine function request is made in accordance with setup. Alternatively, the latter case may be performed if a play stop request is made.
  • Further, a playback of a content in a mobile device may be abnormally stopped or ended. In this instance, the mobile device can activate a time machine function automatically or manually. In this instance, the ‘abnormal’ means when a screen is abnormally switched or ended in the course of watching. For instance, a time machine function may be activated in one of when a power is turned off while a content is played due to a battery shortage or the like, when a play is ended without using a separate content play stop button or that a power is forced to be turned off, a case of a reset due to other errors of a mobile device, or when a content reception is impossible or delayed due to network error or environment (e.g., deviation from a service area, etc.).
  • The time machine function may be provided based on such signaling information related to A/V playback as PID information, time information, frame information and GOP information of a content received via a main device or another digital device and the like. Further, a mobile device can provide a prescribed region of a screen with a UI including a size of a storage space remaining in a storage medium, data of a time machine function available time in accordance with the size of the storage space and the like while storing a content in accordance with a time machine function activation.
  • In association with a time machine function execution, a mobile device can receive and store signaling information on a content only for a part after a time machine request. In this instance, the mobile device provides a user with information based on each signaling information, creates a control signal for a content selected based on the provided information, transmits the created control signal to a main device, receives the corresponding content from the main device in a previous manner, and then provides the received content to the user.
  • Due to a limited storage capacity, storage/play time/speed and the like, a mobile device transmits a control signal to a main device. The mobile device performs a time machine function on a UI only. As a time machine function of the main device is actually activated, a content can be saved in a corresponding storage medium. In this instance, the mobile device creates and transmits a control signal in response to a play request made by a user, receives a corresponding video from the main device, and then provides the received video.
  • In the above description, if the storage space of the mobile or main device becomes in short due to the time machine function execution, it can use an external storage space (e.g., an external hard disc, an IP server, a USB device, a PMP, a PSP, an X-BOX, a cloud server, etc.). Alternatively, it can secure a storage space is secured by deleting an oldest storage capacity. Alternatively, it can secure a storage space in a manner that a later part is not saved.
  • Further, when the storage space is insufficient, as mentioned in the above description, it can reduce a storage capacity itself by deleting an advertisement part and the like randomly or in accordance with settings despite a part saved in a time machine process. In addition, it can provide various kinds of UIs for convenience of identification for the storage space.
  • When a storage space allocated for a time machine function and a storage space allocated for recording/recording reservation differ from each other in location or address, a recording/recording reservation mode is entered in the course of performing the time machine function and a content may be then saved in the storage space allocated for the recording/recording reservation.
  • A mobile device can randomly change settings when activating a mini TV or a time machine despite user's settings for the related function. For instance, even if a user sets a screen of a mobile device to be turned off in the absence of any touch in a first time, it can automatically control the screen to stay on after expiration of the first time in the course of activation of the mini TV or the time machine function. In particular, attributes of functions related to each other can be randomly changed and serviced in accordance with the attributes of the respective functions.
  • On the contrary, if the time machine function is activated, the mobile device can randomly set or service the screen to be turned off for saving the battery and the like despite the settings even if the first time does not expire. In this instance, the above service may be provided only if a remaining level of the battery is within a prescribed range.
  • In consideration of at least one of a remaining battery level and a storage capacity of the mobile device and/or the main device at the play stop or end request timing point, a mobile device may not activate a time machine function automatically. In this instance, a UI for indicating that the time machine function will not be automatically activated is provided to encourage user's convenience. This may identically apply to when a user makes a separate request for a time machine function.
  • Thus, it can solve the problems and/or inconveniences due to a limited size of a storage capacity of a mobile device and the like. If a user touches or taps to select an any region of a screen to which a currently played content is being provided, referring to FIG. 28, a mobile device can provide various UIs (or panels) 2810 and 2820.
  • In addition, each of the panels 2810 and 2820 may be provided or disappear individually in response to a touch to a corresponding region or the like. In particular, while a content is played, an icon 2815 indicating a pause and/or stop is provided to a center of a screen in accordance with a play state of the content. For a pause state, an icon indicating a play and/or stop may be provided. In this instance, a corresponding function may be activated in accordance with an access to the icon.
  • The control panel 2820 is provided to a bottom end of the screen. In particular, in association with a time machine, a UI for various identification information corresponding to the icon access can be configured and provided to a play bar. For instance, referring to FIG. 28, a mobile device can provide a play bar within a control panel with a first icon 2824 indicating a play stopped point at a play stop icon selected point and a second icon 2828 indicating a play point at current hour after the play stopped point when activating a time machine function together with a selection of the play stop icon.
  • Further, the play bar provides a start hour and an end hour of a content using a horizontal rod shape. On the play bar, a rod 2822 ranging from the start hour to the first icon 2824 is colorized, highlighted or focuses to indicate that the content has been played up to the corresponding part. This may be implemented by being discriminated from another rod 2826 ranging from the first icon 2824 to the play end hour.
  • Further, as the time machine function is provided, if the second icon 2828 is created, the rod 2826 between the first icon 2824 and the second icon 2828 may be preferably provided by being discriminated from the rod 2826 ranging from the second icon 2828 to the end hour as well as the rod 2822 between the start hour and the first icon 2824. For instance, the respective rods are differentiated from one another in color to be easily perceived by a user. In another instance, the respective rods are differentiated from one another in type, level and size of focusing/highlight and the like.
  • Assuming that the rod moves from left to right in accordance with a flow of time, the above-mentioned second icon indicates that a playback is being performed on a prescribed level in accordance with a time machine function activation. In this instance, the second icon is not a final point until the end of the time machine function.
  • Hence, the second icon can be differentiated from the first icon 2824 in shape, color, size and the like. Even if the time machine function is ended, a user can select a play point at a current time instead of a time machine part (i.e., a section between a time machine start and a time machine end).
  • In this instance, the mobile device configures a third icon within the play bar to cover a section between the second icon 2828 and an end hour. In particular, the third icon may be configured identical to the first icon 2824 for example. Therefore, the above configuration enables a user to recognize that a time machine function is applied to a content despite that the user did not select a time machine function applied part. In addition, the above configuration provides the user with convenience in playback and the like thereafter.
  • Further, a time machine function may be activated for a single content several times as well as one time. In this instance, icons are appropriately configured to provide a user with convenience in selection. When a plurality of time machine icons are configured and provided in accordance with several activations, a plurality of the time machine icons are provided by being discriminated from one another. Alternatively, a plurality of the time machine icons may be provided by being configured identical to one another for the purpose of time machine function identification.
  • FIG. 29 is a diagram illustrating another example of a method of providing a time machine function in a mobile device. A mobile device can provide various related functions such as a bookmark function and the like together with the above time machine icons. When there is an incoming call while a content is being played via a mobile device, as shown in FIG. 29(a), the mobile device immediately stops playing the content, activates a time machine function, and provides a UI for a cell reception. Alternatively, the mobile device provides a content played screen with a UI indicating that there is the incoming call and then switches the screen, as shown in FIG. 29(b), in response to a selection made by the user.
  • In the latter case, if the screen is switched in response to the selection made by the user, as shown in FIG. 29(b), the played content is paused and the time machine function may be activated. Alternatively, in the latter case, a video call or a call connected state is displayed on a prescribed region of a content provided screen, the content continues to be played, and audio is eliminated only. Therefore, it can control a phone call to be enabled while the user enjoys the video.
  • If the call is ended, the screen shown in FIG. 28 or FIG. 30 is provided to control operations after the time machine function. Further, if a message, a mail, an information update or the like occurs in the course of playing a content in a mobile device, the above description may be similarly applicable to a corresponding service.
  • After a user has made a request for a time machine function activation, if the user makes a request for deactivating the time machine function or intends to preview the content attributed to the time machine function activation up to now before the end, the mobile device can provide a UI shown in FIG. 30. FIG. 30 is a diagram of a UI.
  • Referring to FIG. 30, a list 3010 of video screens saved in accordance with time machine function application by a prescribed time unit is provided to a prescribed region except the aforementioned control panel 2820. For instance, referring to FIG. 30, the video screens are provided as a list from an initial time machine function start point by 2-minute unit from a current video. In this instance, each list can provide a thumbnail image and may include related information as well.
  • Referring to FIG. 30, unlike FIG. 28, a recording button 3020, a current broadcast button 3030, a time machine list button 3040, recording reservation button 3050, a channel list and the like may be provided to the control panel if paged. In particular, for example, if a user intends not to check a time-machined content due to a long time machine time, a considerable amount of a stored content, or an insufficient time, the recording button 3020 is provided to switch a time machine function to a recording function. If the recording button 3020 is selected, a current screen may be switched to EPG screen. This can be done by the recording reservation button 3050 as well.
  • The current broadcast button 3030 is provided to switch to a currently broadcasted screen together with a time machine end. The time machine list button 3040 can page a corresponding content or a whole time machine list including the corresponding content. The recording reservation button 3050 pages EPG, provides a series, retransmission and rebroadcast channel of a corresponding content, information on the corresponding content and/or a related UI as well as the above-mentioned functions.
  • Referring to FIG. 30, thumbnail images of previous times in accordance with a set time reference by starting with a thumbnail image of a video currently played on a screen are extracted with reference to the set time reference and are then provided to the screen. In this instance, the mobile device may provide a thumbnail image in accordance with the settings or may provide detailed information on a content currently saved after the time machine function activation only.
  • Unlike the UI shown in FIG. 30, a UI may be configured by a frame unit in order to facilitate a saved content to be viewed in accordance with time machine function activation or to be edited like an editing after moving picture photographing. In this instance, a frame selected by a user may be enlarged and provided to a prescribed region (e.g., a region right below or above a corresponding frame within UI, a whole screen provided region, etc.).
  • Based on a separate editing button or a selection or action requested for editing, a selected frame may be deleted, moved, copied, or cut. Further, in FIGS. 28 to 30, if a region to which a UI is not provided is selected by a touch or the like, previously provided UIs may be deleted from the screen entirely or in part.
  • If the UI shown in FIG. 30 has difficulty in being provided to a single screen due to a size of the screen, the mobile device can configure the UI to enable a user to check a desired content by moving the UI by flicking or the like. The UIs provided in FIGS. 28 to 30 are the embodiments configured for the description of the present invention for clarity, by which the scope of the appended claims and their equivalents is non-limited.
  • Further, regarding a time machine function, a mobile device may configure and provide a UI shown in FIG. 31 unlike the former UI shown in FIG. 28 or FIG. 30. This UI configuration allows a user to perceive a time machine function more visually, i.e., intuitively. According to the above UI configuration, if a time machine function is activated, since a play of a content is stopped, it may be unable to provide an image for a video to a whole screen. Instead, if a UI for user's control convenience is provided in the course of a time machine function activation or at an end timing point of the time machine function, it can enhance user's convenience.
  • FIG. 31 is a diagram of a mobile device. Referring to FIG. 31, in association with a time machine function, a mobile device can provide an identifier for identifying a mode or type of a screen, a content screen (when outputting a still image), a play bar, a play control icon, a function icon, an audio control icon and the like. In particular, the play bar may be implemented into the former play bar described with reference to FIGS. 28 to 30.
  • In addition, the play control icon may include an icon for stop, an icon for play, an icon for pause, an icon for fast rewind, an icon for fast forward wind, an icon for recording control and the like. In particular, the function icon may include an icon for moving to a current broadcast screen, a recording list request icon, a recording reservation screen paging icon, a channel list providing icon and the like.
  • Further, the recording list request icon or the channel list providing icon may provide a list other than a played content. If the recording reservation screen paging icon is selected, EPG may be paged and provided. However, an initially provided EPG screen may be provided by being configured with reference to a corresponding content or a channel of the corresponding content for example.
  • If the channel list providing icon is selected, a channel video list may be paged. If a video is unseen, a channel number and a program title may be displayed. In addition, a time machine function may be duplicatively performed on currently broadcasted channels. In another instance, digital devices according to an embodiment of the present invention can perform a mini TV function using sensing information. In this instance, the sensing information may be received from at least one of a main device and a mobile device. In particular, the sensing information may be generated from at least one of a camera sensor, a weight sensor, a gyro sensor, a gravity sensor, a location sensor, a contact sensor and the like, which are provided to each of the devices. Therefore, each of the digital devices further includes a sensor and a sensing circuit in accordance with the above-mentioned configuration. Subsequently, a control unit processes the sensing information and can then transmit a control signal to a corresponding configuration or another device.
  • For instance, assume that a camera sensor is provided to a mobile device and that the mobile device is activating a mini TV function by being paired with a main device. The camera sensor can obtain sensing information on an object consecutively or by prescribed periods in the course of the mini TV function activation. While a user activates a mini TV function via a mobile device, if a prescribed interruption occurs, it may be to control the active mini TV function. In this instance, the interruption may include a case of activating such a mobile dedicated function as a phone call function and the like, when a user is temporarily doing something else instead of watching a mini TV, or the like.
  • When the interruption includes such a mobile dedicated function as a phone call function, the mobile device may control the active mini TV to be stopped or time-shifted immediately. If the interruption includes the case that a user is doing something else, considerable attention should be paid to stopping or time-shifting the mini TV. Since the mobile device has difficulty in obtaining user's intension precisely, if a control differing from the user's intention is performed, it may cause inconvenience to the user. To this end, the present invention intends to use sensing information.
  • If sensing information is obtained from a camera sensor by 3-second periods, a control unit can determine user's intention using the sensing information. For instance, if an object recognized from the obtained sensing information keeps being recognized, the control unit controls a mini TV function keeps being activated. However, if an object different from a previously recognized object is recognized, the control unit can create a control signal by further referring to at least one sensing information consecutively received rather than to stop activating the mini TV function.
  • If a different object is recognized from at least two sensing information received thereafter, the control unit can control the mini TV function to stop being activated from the corresponding timing point. In this instance, a previously recognized object means one object that is not a vacant space at least. An object different from the previously recognized object includes one object or a vacant space having no object exist therein. On the other hand, if the control unit has difficulty in identifying an object from received sensing information, the control unit may adjust a camera angle or process the object into a non-existing object.
  • When the control unit receives sensing information by prescribed periods, if an object different from a previously recognized object is recognized from the sensing information for faster and more accurate control, the control unit may set a camera sensing period to differ from a previously set camera sensing period, obtain consecutive sensing information, and use the obtained sensing information for a control. The control unit may adjust a sensing angle of a camera sensor together with or separately from the sensing period, obtain sensing information at a different angle, and use the obtained sensing information for the control.
  • Further, the control unit may control a pause or time shift function to be activated in accordance with a live broadcast, a previously saved broadcast or a different content, i.e., a content type. Before the pause or time shift function is activated, the control unit may configure a corresponding UI, provide a user with the configured UI, and activate the corresponding function in accordance with a selection made by the user.
  • A case of using a contact sensor as a substitute for a camera sensor is described, for example, as follows. This case is overall similar to the above-mentioned case of using the camera sensor but slightly differs in a reference for determination. Hence, the aforementioned duplicative description is omitted from the following description and different matters shall be mainly described in the following description.
  • First of all, a control unit obtains sensing information from a contact sensor or a heat sensor continuously or by prescribed periods. In this instance, the contact sensor is provided to determine whether a user is handling a mobile device in direct. In addition, the contact sensor may be provided to lateral and/or rear side of the mobile device. When a mini TV function is activated via a mobile device, the contact sensor is used because a user generally holds the mobile device in his hand(s) in order to facilitate the mobile device to be handled rather than to fix the mobile device to a prescribed position. So to speak, if a mobile device is not handled in user's hand(s), it may be highly possible for the user not to use a mini TV function on account of the experience in using the mobile device.
  • Therefore, the control unit extracts user's contact information and/or heat information from the continuously received sensing information obtained from the contact sensor and/or the heat sensor and then determines whether the user is watching the mini TV function. In this instance, regarding the heat information, a reference value may be set by considering the temperature generated from the mobile device and a prescribed temperature range added to a temperature of hand with reference to human body temperature at least. When the heat information is used, only if the temperature given by the heat information is lower than the reference value, the control unit determines that the user is not watching the mini TV function and then controls the pause or time shift function to be activated in accordance with the content type.
  • The control unit may consider both of the sensing information of the camera sensor and the sensing information of the contact sensor and/or the heat sensor. The control unit prioritizes the sensing information of the camera sensor and the sensing information of the contact sensor and/or the heat sensor by giving higher priority to the camera sensing information. If an object different from a previously sensed object is sensed based on the camera sensing information, the control unit obtains the sensing information of the contact sensor and/or the heat sensor and then uses the obtained sensing information for the control. Alternatively, sensing information may be obtained in a manner that the sensing periods of the respective sensors are set equal to each other or set not to overlap with each other. This may identically apply to a gyro sensor. If a user uses a mini TV via a mobile device, the user may watch the mini TV in the course of moving in general. Hence, if error of the sensing information input via the gyro sensor is equal to or smaller than a reference value, the control unit may determine that the user is doing something else without holding the mobile device in his hand.
  • For the time shift, the control unit performs a time shift function within a surplus space only in consideration of capacity of a built-in storage unit of a mobile device. If there is no surplus space, the control unit makes a request for a time shift to a main TV or stops the time shift function not to further play a corresponding content. In the latter case, if data in a previously saved space has a low priority or is not significant, the data is deleted to secure a storage space. In continuation with the above description, the control unit can secure a space using a web server like a cloud server or may secure a sufficient storage space using a cloud server from the beginning.
  • Further, when a prescribed channel or a content of a broadcast serial is controlled to be continually played back, the control unit controls the corresponding content of the corresponding channel or the corresponding installment in the above manner only and may stop playing the rest of the content or installments.
  • Moreover, the control unit determines user's intension further using sensing information received via a plurality of sensors provided to the mobile device in addition to the above-described sensors and can then use the determination for a corresponding control.
  • Further, sensing information may be provided to a main device as well as a mobile device. In this instance, the main device can perform a control function in a manner almost equal to that of the aforementioned method of using the sensing information in the mobile device. Further, even if a mini TV function is used via a mobile device, a control unit of the mobile device can refer to the sensing information of the main device as well. For instance, since the main device generally includes components (e.g., an image processor, etc.) functionally better than those of the mobile device, the mobile device receives the sensing information obtained by the main device and then uses the received sensing information for the control.
  • Besides, if each sensing information is set to be activated/deactivated on a prescribed region of a screen in case of mini TV function activation, it can prevent such inconvenience as a control that deviates from user's intention. In addition, it can provide UI information to enable a user to set a reference value randomly for a factor of sensing information that affects a control operation of a control unit.
  • FIG. 32 and FIG. 33 are flowcharts for a mini TV providing method according to an embodiment of the present invention. Referring to FIG. 32, in a method of processing a mini TV service according to one embodiment of the present invention, if a mobile device activates a prescribed application (S310), the mobile device is paired with a main device by the active application (S320).
  • The mobile device transmits a control signal for a mini TV to the main device in response to a prescribed selection made by a user or a prescribed action performed by the user (S330) and then output data received from the main device to a screen (S340). In addition, the mini TV service processing method according to an embodiment of the present invention may further include at least one of the steps of receiving a signal for an output change from the main device, determining whether to switch an output video based on the output change signal received from the main device, and controlling an output of the main device by creating a signal for an output video change of the mobile device and then transmitting the created signal to the main device.
  • Referring to FIG. 33, in a method of processing a mini TV service according to another embodiment of the present invention, a mobile device is paired with a main device (S410). After the pairing step S410, the mobile device receives an input of a user's selection or action (S420). Based on the received input of the user's selection or action, the mobile device receives video data from the main device and then outputs the received video data to a screen (S430). The mobile device also transmits a signal including video data to the main device and then controls the main device to output the transmitted signal including the video data (S430).
  • In addition, the mini TV service processing method according to an embodiment of the present invention may further include at least one of the steps of activating a prescribed application in the mobile device, receiving a signal for an output change from the main device, determining whether to switch an output video based on the output change signal received from the main device, and controlling an output of the main device by creating a signal for an output video change of the mobile device and then transmitting the created signal to the main device.
  • In this instance, the prescribed application may include a remote application. The mini TV may include one of hardware provided to the mobile device, an application activated in the mobile device, a function activated in the mobile device, and software activated in the mobile device. The mini TV receives output video data of the main device and/or output video data of a different device paired with the main device and then outputs the received output video data to the mobile device. Alternatively, the mini TV controls an output of the main device or an output of the different device paired with the main device to be adjusted, changed, or adjusted.
  • The above-mentioned prescribed selection may be made via an icon for an activation of the mini TV, which is provided by each depth or step in a UI provided by the mobile device. The above-mentioned prescribed action may include at least one of a quick rapid movement or shaking toward the main device, a drag & drop operation of a prescribed item in the UI provided by the mobile device in prescribed direction, and a drag or flicking in prescribed direction by touching a prescribed region within the screen of the mobile device. In addition, the prescribed action may include at least one of a capture of a screen of the main device by the mobile device and a drag & drop operation of image data output to the mobile device onto a prescribed region.
  • Further, the above-mentioned mini TV may be provided as a landscape or portrait screen in accordance with attributes of a screen configuration. In particular, the landscape or portrait screen may be provided on the basis of current inclination information of the mobile device. Alternatively, the landscape screen and the portrait screen may be provided by being switched to each other in accordance with current inclination information of the mobile device. Alternatively, the landscape or portrait screen may be provided as a default. For clarity, the above descriptions relate to the examples of providing a landscape screen as a default due to the property of a broadcast screen.
  • FIG. 34 and FIG. 35 are flowcharts for a method of providing a time machine function in a mobile device. Referring to FIG. 34, in a method of processing a mini TV service according to one embodiment of the present invention, a prescribed application is activated in a first device (S510).
  • The first device is paired with a second device in response to the activation of the prescribed application (S520). The first device transmits a control signal for a mini TV activation to the second device in response to a first request for the mini TV activation (S530).
  • The first device outputs a content received from the second device to a screen (S540), and the first device stops a playback of a content output based on a second request for a time machine function and provides a first UI including first time machine information on a play point in case of the second request and second time machine information on a current point to a prescribed region of the screen (S550).
  • Thereafter, the first device outputs a content to the screen in response to a third request for the playback of the content (S560). In particular, the first UI may include a play bar. The first time machine information and the second time machine information are displayed in the first UI by being discriminated from each other. For instance, the first time machine information and the second time machine information are configured to differ from each other in color and/or size. For another instance, the first time machine information and the second time machine information may be discriminatively displayed in a manner that the second time machine information includes at least one of highlight, focusing, thumbnail image and visual indicator, which are not included in the first time machine information.
  • In particular, the first request is made via an icon for the mini TV activation, which is provided by each step in the UI provided by the first device. Alternatively, the first request may be made via at least one of a quick rapid movement or shaking toward the second service, a drag & drop operation of a prescribed item in the UI provided by the first device in prescribe direction, a drag or flicking in prescribed direction by touching a prescribed region in the screen of the first device, a capture of a screen of the second device by the first device, and a drag & drop operation of image data output to the first device onto a prescribed region.
  • In particular, the second request is made via a phone call to the first device or an icon for the time machine activation, which is provided by each step in the UI provided by the first device. Alternatively, the second request may be made via at least one of an action of shaking the first device in prescribed direction, a touch & drag of a prescribed region in the screen of the first device in prescribed direction, a flicking of a prescribed region, and a drag & drop operation to a prescribed region.
  • Optionally, the above-mentioned service processing method may further include at least one of the steps of outputting a second UI for a playback control of a content output to the screen in response to the third request, receiving a signal for an output change from the second device, determining whether to switch an output video based on the received signal for the output change of the second device, and controlling an output of the second device by creating a signal for an output vide change of the first device and then transmitting the created signal to the second device.
  • Besides, the first device may include a mobile device, the second device may include a digital broadcast receiver, and the prescribed application may include a remote application. Referring to FIG. 35, in a method of processing a mini TV service according to another embodiment of the present invention, a first device is paired with a second device. The first device receives video data from the second device and then outputs the received video data to a screen, based on a first request for the mini TV activation. Alternatively, the first device transmits a control signal including the video data to the second device (S610).
  • The first device stops playing a content output based on a second request for a time machine function and provides a first UI including first information on a play point in case of the second request and second information on a current point to a prescribed region of the screen (S620). Thereafter, the first device outputs a content to the screen in response to a third request for the playback of the content (S630).
  • In addition, FIGS. 36-46 illustrate an alternative embodiment of the present invention. In this embodiment, a display device interfaces with a mobile terminal and the display device and mobile terminal are controlled based on an eye movement and/or a grip pattern of a user.
  • In more detail, FIG. 36 illustrates a display device 3600 interfacing with a mobile terminal 3610. In particular, FIG. 36(a) illustrates the display device 3600 including camera units 3620 that are able to capture and view an eye movement of a user using the mobile terminal 3610. In FIG. 36(a), the user's eyes are viewing the mobile terminal 3610.
  • FIG. 36(b) illustrates the user's eyes facing the display device 3600. FIG. 36(c) illustrates the user's eyes looking away from the mobile terminal 3610 as well as the display device 3600.
  • According to an embodiment of the present invention, the display device 3600 performs different functions based on the user's eye movement. These features will be described in more detail with respect to FIG. 37. In addition, it is respectfully noted the display device 3600 in FIG. 36(a) includes two camera units 3620. This is just an example and any number of camera units may be disposed around the display 3600 in order to sufficiently capture the eye movement of the user holding the mobile terminal 3610. In more detail, the camera unit 3620 can include a face recognition process for recognizing facial expressions of the user, and then the controller of the display device 3600 can determine the eye movement of the user by analyzing the facial expressions of the user. In an alternative embodiment, the mobile terminal 3610 can use the camera included on the mobile terminal 3610 to capture the facial expressions of the user, and then transmit this information to the display 3600. That is, the mobile terminal 3610 already includes a camera and thus the camera can be used to determine the eye movement of the user using the mobile terminal 3610. For example, the camera unit of the mobile terminal 3610 or the camera units 3620 of the display device 3600 can tell whether the user's eyes are looking at the mobile terminal 3610, looking at the display device 3600 or looking away from both the mobile terminal 3610 and the display device 3600 (as shown in FIGS. 36(a)-(c)).
  • Based on the different eye movements of the user, the streaming operating of the display device 3600 is controlled to provide an enhanced service to the user and to save power and energy.
  • Turning next to FIG. 37, which is flow chart illustrating a method of controlling the display device 3600 and mobile terminal 3610 according to an embodiment of the present invention. The operations performed in FIG. 37 can be performed by the control unit of the display device 3600 or in an alternative embodiment controlled by the control unit of the mobile unit 3610. Thus, the control units of the display device 3600 and the mobile terminal 3610 can cooperate with each other in order to provide commands between each device.
  • As shown in FIG. 37, the control unit of the display device 3600 determines whether the control operation is to be based on the user's eye movements, the user's grip pattern on the mobile terminal 3610 or both (S900). This feature can be set by the manufacturer of the display device, mobile terminal or can be set by the user. For example, the user may set the display device 3600 or mobile terminal 3610 to perform the control method using only the eye movement of the user, using only the grip pattern of the user or using both the eye movement and grip pattern of the user.
  • If the user's eye movement is set as the control method, the controller determines whether the user's eyes are looking at the display device 3600 (S910) (this is shown in FIG. 36(b)). If the user's eyes are looking at the display device 3600 (yes in S910), the control unit turns off the streaming of the video contents displayed on the display device 3600 to the mobile terminal 3610. That is, as discussed above, the user can view contents on their mobile terminal 3610 that are displayed on the display device 3600. Thus, if the user was watching a program on the display device 3600 and had to leave the room in order to go to the kitchen or bathroom, for example, the user can have the contents currently being displayed on the display device 3600 displayed on the mobile terminal 3610. Thus, the user can view the streamed contents on their mobile 3610 while they leave the room including the display device 3600.
  • In step S910, the control unit determines whether the user's eyes are looking at the TV. If they are looking at the TV (yes in S910), the control unit of the display device 3600 automatically stops streaming the data that was being streamed to the mobile terminal 3610, because the user is not looking at the mobile terminal, but rather has moved their eye pattern to look at the display device. Thus, the battery power of the mobile terminal 3610 is saved and any extra streaming charges are avoided.
  • On the contrary, if the user's eyes are not looking at the TV (no in S910), the control unit determines whether the eyes of the user are looking at the mobile terminal 3610 (S930) (as in FIG. 36(a)) or looking away from both the mobile terminal 3610 and the display device 3600 (as shown in FIG. 36(c)). If the user's eyes are looking at the mobile terminal (yes in S930), the control unit maintains the streaming operating between the display device 3600 and 3610 or if the streaming operation has not started, starts the streaming operation (S940). In more detail, if the control unit determines the user's eyes are looking at the mobile terminal 3610, the control unit can advantageously determine that the streaming operation should continue or should start because the user's eyes are looking at the mobile terminal 3610 and are not looking at the display device 3600.
  • Alternatively, if the user's eyes are not looking at the mobile terminal and are not looking at the TV (no in S910 and no in S930), the control unit of the display device 3600 automatically starts a time-shift record process in which the contents displayed on the display device 3600 are recorded (S950). Thus, if the user was interrupted while watching the display device 3600 and had to turn around to welcome a guest entering their home, or for any other reason, the display device 3600 automatically records the data being displayed on the display device 3600. Thus, the user can easily go back to viewing the contents that they missed when they were distracted from viewing the program. Thus, according to the present embodiment, the user can easily watch a video program on the display device 3600, on the mobile terminal 3610 or view recorded contents without requiring any particular input operations, because the display device analyzes and determines their eye movement and then advantageously controls the display device 3600 and the mobile terminal 3610.
  • The right side of FIG. 37 illustrates the user's grip pattern on their mobile terminal being used to perform different functions. In particular, the user tends to grip their mobile terminal using the same grip patterns for each of the different functions. For example, the user has a first grip pattern when making a phone call, a second grip pattern when viewing a video file, a third grip pattern when texting, a fourth grip pattern when searching the Internet, a fifth grip pattern when taking a picture, etc. Thus, based on the different grip patterns, the control unit of the mobile terminal 3610 or the display device 3600 can perform specific operations. FIGS. 39-46 illustrate different grip patterns corresponding to different functions executed on the mobile terminal (these Figures will be described in more detail later). Thus, returning to FIG. 37, the control unit determines whether the grip pattern corresponds to the user viewing contents (S960). If the user is viewing contents (yes in S960), the control unit either maintains the streaming operation between the display device 3600 and the mobile terminal 3610 or turns on the streaming operation (S970). The control unit can then determine if the user's grip has changed (S990). If the user's grip has not changed (no in S990), the operation in step S970 is continued. However, if the user's grip has changed (yes in S990), the control unit can perform a function based on a new grip pattern (S1000).
  • Alternatively, if the user's grip pattern does not correspond to the user view contents (no in S960), the control unit performs a function based on the grip pattern. The below Table 1 illustrates different functions being performed for different grip patterns (S980).
  • FIG. 37 also illustrates both the user's eye movement and grip pattern being used in order to determine how to operate functions between the mobile terminal 3610 and the display device 3600 (S1010).
  • In more detail, the below Table 1 illustrates functions being performed by different eye patterns and grip patterns. The user can also define their own grip patterns and what functions should be executed based on the grip pattern.
  • TABLE 1 Function Eye Pattern Looking at TV Turn off mobile terminal streaming operation Looking at mobile terminal Maintain or turn on streaming Looking away from TV and Turn off mobile terminal streaming time/shift mobile terminal record Grip Pattern Phone call grip Stop streaming to mobile terminal; time shift TV Viewing video grip Turn on/maintain streaming to mobile terminal Texting grip Display/execute (overlay) text window Internet searching grip Display/execute Internet browser Camera grip Execute/turn on camera Undefined grip Notify user User-defined grip Refer to function table User-defined Grip Grip Pattern # 1 Texting Grip Pattern # 2 Video watching Grip Pattern # 3 Phone calling Grip Pattern # 4 Internet searching/viewing Grip Pattern # 5 Camera Grip Pattern # N User-defined function
  • Thus, with reference to Table 1, the control unit can determine the eye pattern, grip pattern or both in order to determine what function is executed. As discussed above, if the user is looking at the display device, the control unit can turn off the mobile terminal streaming operation. If the user is looking at the mobile terminal, the control unit can maintain or turn on the streaming operation. If the user is looking away from the mobile terminal and the display device, the control unit can turn off the streaming operating and/or perform a time shift recording operation. These features are discussed above with respect to FIG. 37.
  • Regarding the grip patterns, if the grip pattern corresponds to a phone call grip pattern, the control unit can stop the steaming operation between the display device 3600 and mobile terminal 3610 and/or can start a time shift recording operation. FIG. 43 illustrates the grip pattern for a phone call operation. Thus, if the user is watching a streaming operation on their mobile terminal 3610 from the display device 3600 and receives an incoming call, the control unit of the display device 3600 or the mobile terminal 3610 automatically stops streaming the contents to the mobile terminal and/or starts a recording operation. Thus, the user can answer the phone call and then return to viewing the contents.
  • In addition, if the grip pattern is viewing a video or contents on the mobile terminal 3610, the control unit can maintain the streaming operation to the mobile terminal or if the streaming operation has not yet started, to start the streaming operation. Thus, the user can merely grab their mobile terminal using the video viewing grip, and the control unit automatically either starts the streaming operation or maintains a current streaming operation.
  • Further, as shown in Table 1, the user also has a particular grip when texting. Thus, when the grip pattern indicates the user is texting or beginning to text, the control unit can display or execute a text window on the mobile terminal 3610. In more detail, if the user is watching a streamed video on their mobile terminal 3610 and wants to let another user know about the video, the user may want to start a text message session with the other user. In the present invention, the user merely needs to grip the phone using their standard text grip pattern and the control unit automatically displays a text window on the mobile terminal 3610. In addition, so that the user can continue to watch the streaming operation, the control unit can display the text message window in an overlaying manner on the content being displayed on the mobile terminal 3610. Alternatively, the control unit may display the text message window on the display device 3600.
  • In addition, one example of using both the user's eye movement and grip pattern is as follows. If the user is watching a video streaming operation on their mobile terminal 3610 and wants to text another user, the user may grab the phone using their standing text gripping pattern. Then, the control unit starts or executes the text messaging process. If the user then stops looking at the mobile terminal 3610 and looks at the display device 3600, the control unit can automatically display the text messaging window on the display device 3600 rather than on the mobile terminal 3610. Thus, in this example, both the grip pattern and user's eye movement are used in order to determine the operations to be controlled. This is true for each of the grip pattern and eye patterns discussed in Table 1 and the above description.
  • Similar comments apply to the Internet searching grip. That is, FIG. 45 illustrates one example of a grip pattern used when searching the Internet. Thus, when the control unit determines the grip pattern in FIG. 45 holding the mobile terminal, the control unit can display or execute an Internet browser on the mobile terminal 3610. Again, if the user's eye movement moves away from the mobile terminal 3610 towards the display device 3600, the control unit can execute or display the Internet browser on the display device 3600 instead of the mobile terminal 3610. This is another example of using a combination of the user's eye movement and grip patterns when determining the operation to be performed.
  • Another grip pattern is when the user is taking a picture. FIG. 46 illustrates the user taking a picture of himself and a friend. Thus, in this example, the user has a particular grip pattern as shown in FIG. 46 that indicates the user is taking a picture. The control unit can then execute or turn on the camera function based on the camera grip pattern. If the user was watching a streaming operation prior to gripping the mobile terminal 3610 using the camera grip pattern, the control unit can stop the streaming operation between the display device 3600 and mobile terminal 3610, because the user is using the mobile 3610 as a camera.
  • Table 1 also illustrates an undefined grip pattern. In particular, if the control unit cannot determine the grip pattern and what function to perform, the control unit can notify the user that the grip pattern is undefined. Table 1 also illustrates user-defined grip patterns. In particular, the user can set particular grip patterns and particular functions. For example, the user can set a first grip pattern to be a texting grip pattern, a second grip pattern to be a video watching grip pattern, a third grip pattern to be a phone calling grip pattern, etc. These features are illustrated in the bottom portion of Table 1.
  • Thus, according to the present invention, the grip pattern and user's eye movement can be used individually or in combination to determine what function should be performed on the display device, the mobile terminal or between the display device and the mobile terminal.
  • Turning now to FIGS. 38-46, which illustrate features regarding the different grip patterns. In particular, FIG. 38 is an overview of a mobile terminal 3610 including a plurality of sensors 3620. In particular, the sensors 3620 can be placed around the mobile terminal 3610 in order to determine the different grip patterns of the user. The sensors can be pressure sensors, for example, which can determine pressure being applied by the user's fingers. The sensors 3620 in FIG. 38 are merely examples, and the sensors can be placed in different patterns. For example, the sensors 3620 can be placed on particular areas of the mobile terminal 3610 which receive a grip pattern from the user. The positions include top surfaces, side surfaces and bottom surfaces of the mobile terminal 3610. Thus, using the sensors 3620, the control unit can determine the grip pattern of the mobile terminal 3610. In addition, the control unit of the mobile terminal 3610 can determine the grip pattern of the user gripping the mobile terminal 3610 and then transmit this information to the control unit of the display device 3600 as discussed above.
  • Next, FIG. 39 illustrates the user gripping the mobile terminal 3610. As shown in FIG. 39(a), the particular grip pattern may correspond to a video viewing grip pattern. Thus, when the user grips the mobile terminal 3610 using the grip pattern shown in FIG. 39(a), the control unit can determine that the grip pattern corresponds to a viewing video grip pattern. FIG. 39(b) illustrates the different areas touched in FIG. 39(a). Thus, when the mobile terminal 3610 determines the grip pattern corresponding to that shown in FIG. 39, the function can be executed based on this particular grip pattern.
  • FIG. 40 illustrates another example of a viewing video grip pattern. As shown in FIG. 40(a), the user is currently viewing a video. Note that the grip pattern in FIG. 40(a) is slightly different than the grip pattern shown in FIG. 39(a), but both are grip patterns for the viewing contents. Thus, both of these grip patterns can be designated as viewing video content grip patterns. The user can also set one of these grip patterns to be for video viewing and another to be for picture taking, for example. A table can be stored in the memory such as that shown in Table 1 which includes the different grip patterns and the functions that are performed based on the particular grip patterns. As discussed above, the user can also define what grip patterns correspond to what functions and this information can be stored in the memory.
  • FIG. 40(b) illustrates the different positions touched or gripped by the user of the mobile terminal. In particular, FIG. 40(b) illustrates three positions touched by the gripping of the mobile terminal by the user. In addition, the user is selecting the home button or pressing the home button in FIG. 40(a). This additional information can also be used to determine the grip pattern. In particular, because the grip pattern in FIGS. 40(a) and (b) appear to illustrate the video viewing grip pattern, the control unit can use the additional input operation of the home button to determine whether this particular grip pattern is actually the video grip pattern or a picture taking grip pattern (or other grip patterns). Thus, the user's actions on the mobile terminal can be used to distinguish what grip pattern is being used.
  • FIG. 41 illustrates yet another example of a grip pattern for viewing video contents. As shown in FIGS. 41(a) and 41(b), the grip pattern includes four positions touched by the user's four fingers excluding their thumb. Thus, the control unit can determine from the sensors 3620 what grip pattern is being used. In FIG. 41(b), the sensors can determine that four positions have been gripped, and thus determine this is a viewing video grip pattern.
  • Next FIG. 42 illustrates the mobile terminal 3610 being docked in a docking station 3650. In this example, the control unit of the mobile terminal 3610 determines the grip pattern is actually a docking station 3650. Thus, the control unit can determine the docking station 3650 touches and secures the mobile terminal 3610 on the bottom and lower side surfaces of the mobile terminal 3610 as shown in FIG. 42(b). Thus, in this example, the control unit can determine that the user is viewing video contents, especially when the user's eye movement is directed at the mobile terminal 3610. Thus, in this example, the control unit can either start the streaming process from the display device 3600 to the mobile terminal 3610 or continue the streaming service. This is another example of using a combination of both the grip pattern and the eye pattern of the user in order to determine what function to perform.
  • In addition, as discussed above, FIG. 43 illustrates a user performing a call function. As shown in FIG. 43(a), the user grips the phone with their left hand. FIG. 43(b) illustrates the different touch patterns occurred based on this particular grip pattern. In addition, FIG. 43 illustrates a user gripping the phone with their left hand. However, the user can also grip the phone with their right hand (especially if they are a right handed user) and will have a similar grip pattern as shown in FIG. 43(b) except the grip pattern would be switched.
  • FIG. 44 illustrates a grip pattern used for texting. In particular, FIG. 44(a) illustrates the user gripping the lower portion of the mobile terminal 3610 in which four regions of the phone are touched as shown in FIG. 44(b). Thus, the control unit can determine the user is performing a texting operation based on this particular grip pattern. In addition, as shown in FIG. 44(a), the user's thumbs are actually touching the keypads. Thus, this addition information case be used to determine the grip pattern is particularly for texting. In addition, if the user is currently viewing a streaming operation, the text message window can be overlayed on the currently streamed content and can also be displayed on the display device 3600 when the user's eyes move to the display device 3600 (as discussed above).
  • FIG. 45 illustrates an example of a user performing an Internet searching or reading operation. As shown in FIG. 45, the user is gripping the mobile 3610 with their left hand and is using a pointer device 3660 to access information on the displayed page. Thus, the controller can determine that the mobile terminal has a grip pattern as shown in FIG. 45(b), which corresponds to an Internet searching or similar function. Thus, the control unit can automatically execute an Internet browser or perform other similar functions based on this particular grip pattern.
  • In addition, FIG. 46 illustrates a user taking a picture of himself and a friend. Thus, the control unit can determine the grip pattern includes three touches as shown in FIG. 46(b) and then automatically execute the camera function when the user uses this particular grip pattern.
  • Thus, as discussed above, the present invention provides a method of controlling the mobile terminal and display device based on the grip pattern of the user, the eye movement of the user or both the grip pattern and eye movement of the user.
  • Accordingly, the present invention provides the following advantages.
  • First of all, the present invention provides an interfacing method and environment for communications between a plurality of devices, thereby enabling a service limited to a specific device to be used by various devices more user-friendly.
  • Secondly, the present invention provides an interfacing method and environment among a plurality of devices, thereby providing various kinds of services.
  • Thirdly, the present invention raises product satisfaction for devices, thereby encouraging consumer's desire for purchase.
  • It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
