         [0036]    The image receiving device (sink apparatus)  100  is a broadcast receiver capable of reproducing a broadcast signal, a video content stored in a storage medium, and the like, or a video processing apparatus such as a video player (recorder) capable of recording and reproducing a content, for example. If the image receiving device  100  can be functioned as a sink apparatus, the image receiving device  100  may be a recorder (video recording apparatus) capable of recording and reproducing contents on and from an optical disk compatible with the Blu-ray Disc (BD) standard, an optical disk compatible with the digital versatile disk (DVD) standard and a hard disk drive (HDD), for example. If the device  100  can be functioned as a sink apparatus, may be a set-top box (STB) which receives contents and supplies the contents to the video processing apparatus, for example. 
         [0037]    The control device (source apparatus)  200  is a mobile terminal device (hereinafter referred to as a mobile terminal), such as a mobile telephone terminal, a tablet personal computer (PC), a portable audio player, a handheld video game console, and the like, which includes a display, an operation module, and a communication module, for example. 
         [0038]    The wireless communication terminal  300  is capable of performing wired or wireless communications with each of the image receiving device  100  and the mobile terminal  200 . That is, the wireless communication terminal  300  functions as an access point (AP) of wireless communications of the image receiving device  100  or the mobile terminal  200 . Further, the wireless communication terminal  300  is capable of connecting to a cloud service (a variety of servers), for example, via a network  400 . That is, the wireless communication terminal  300  is capable of accessing the network  400  in response to a connection request from the image receiving device  100  or the mobile terminal  200 . Thereby, the image receiving device  100  and the mobile terminal  200  are capable of acquiring a variety of data from a variety of servers on the network  400  (or a cloud service) via the wireless communication terminal  300 . 
         [0039]    The image receiving device  100  is mutually connected to the mobile terminal  200  via a communication cable (hereinafter referred to as MHL cable)  10  compatible with the Mobile High-Definition Link (MHL) standard. The MHL cable  10  is a cable including a High-Definition Digital Multimedia Interface (HDMI) terminal having a shape compatible with the HDMI standard on one end, and a Universal Serial Bus (USB) terminal having a shape compatible with the USB standard, such as the micro-USB standard, on the other end. 
         [0040]    The MHL standard is an interface standard which allows the user to transmit moving image data (streams) including video and moving images. According to the MHL standard, an electronic device (Source apparatus (mobile terminal  200 )) on the side that outputs a stream outputs a stream to an electronic device (Sink apparatus (image receiving device  100 ) on the side that receives a stream, via an MHL cable. The sink apparatus  100  is capable of causing the display to display video obtained by reproducing the received stream. Further, the source apparatus  200  and the sink apparatus  100  are capable of operating and controlling each other, by transmitting a command to the counterpart apparatus connected via the MHL cable  10 . That is, according to the MHL standard, control similar to the current HDMI-Consumer Electronics Control (CEC) standard can be performed. 
         [0041]      FIG. 2  shows an example of the video processing apparatus  100 . 
         [0042]    The video processing apparatus (image receiving device)  100  comprises an input module  111 , a demodulator  112 , a signal processor  113 , a speech processor  121 , a video processor  121 , a video processor  131 , an OSD processor  132 , a display processor  133 , a controller  150 , a storage  160 , an operation input module  161 , a reception module  162 , a LAN interface  171 , and a wired communication module  173 . The video processing apparatus  100  further comprises a speaker  122  and a display  134 . The video processing apparatus  100  receives a control input (operation instruction) from a remote controller  163 , and supplies the controller  150  with a control command corresponding to the operation instruction (control input). 
         [0043]    The input module  111  is capable of receiving a digital broadcast signal which can be received via an antenna  101 , for example, such as a digital terrestrial broadcast signal, a Broadcasting Satellite (BS) digital broadcast signal, and/or a communications satellite (CS) digital broadcast signal. The input module  111  is also capable of receiving a content (external input) supplied via an STB, for example, or as a direct input. 
         [0044]    The input module  111  performs tuning (channel tuning) of the received digital broadcast signal. The input module  111  supplies the tuned digital broadcast signal to the demodulator  112 . As a matter of course, the external input made via the STB, for example, is directly supplied to the demodulator  112 . 
         [0045]    The image receiving device  100  may comprise a plurality of input modules (tuners)  111 . In that case, the image receiving device  100  is capable of receiving a plurality of digital broadcast signals/contents simultaneously. 
         [0046]    The demodulator  112  demodulates the tuned digital broadcast signal/content. That is, the demodulator  112  acquires moving image data (hereinafter referred to as a stream) such as a TS (transport stream) from the digital broadcast signal/content. The demodulator  112  inputs the acquired stream to the signal processor  113 . The video processing apparatus  100  may comprise a plurality of demodulators  112 . The plurality of demodulators  112  are capable of demodulating each of a plurality of digital broadcast signals/contents. 
         [0047]    As described above, the antenna  101 , the input module  111 , and the demodulator  112  function as reception means for receiving a stream. 
         [0048]    The signal processor  113  performs signal processing such as a separation process on the stream. That is, the signal processor  113  separates a digital video signal, a digital speech signal, and other data signals, such as electronic program guides (EPGs) and text data formed of characters and codes called datacasting, from the stream. The signal processor  113  is capable of separating a plurality of streams demodulated by the plurality of demodulators  112 . 
         [0049]    The signal processor  113  supplies the speech processor  121  with the separated digital audio signal. The signal processor  113  supplies the video processor  131  with the separated digital video signal, also. Further, the signal processor  113  supplies a data signal such as EPG data to the controller  150 . 
         [0050]    Moreover, the signal processor  113  is capable of converting the stream into data (recording stream) in a recordable state on the basis of control by the controller  150 . Further, the signal processor  113  is capable of supplying the storage  160  or other modules with a recording stream on the basis of control by the controller  150 . 
         [0051]    Still further, the signal processor  113  is capable of converting (transcoding) a bit rate of the stream from a bit rate set originally (in the broadcast signal/content) into a different bit rate. That is, the signal processor  113  is capable of transcoding (converting) the original bit rate of the acquired broadcast signal/content into a bit rate lower than the original bit rate. Thereby, the signal processor  113  is capable of recording a content (program) with less capacity. 
         [0052]    The speech processor  121  converts a digital speech signal received by the signal processor  113  into a signal (audio signal) in a format that can be reproduced by the speaker  122 . That is, the speech processor  121  includes a digital-to-analog (D/A) converter, and converts the digital speech signal into an analogue audio (acoustic)/speech signal. The speech processor  121  supplies the speaker  122  with the converted audio (acoustic)/speech signal. The speaker  122  reproduces the speech and the acoustic sound on the basis of the supplied audio (acoustic)/speech signal. 
         [0053]    The video processor  131  converts the digital video signal from the signal processor  113  into a video signal in a format that can be reproduced by the display  134 . That is, the video processor  131  decodes the digital video signal received from the signal processor  113  into a video signal in a format that can be reproduced by the display  134 . The video processor  131  outputs the decoded video signal to the display processor  133 . 
         [0054]    The OSD processor  132  generates an On-Screen Display (OSD) signal for displaying a Graphical User Interface (GUI), subtitles, time, an application compatible/incompatible message, or notification information on incoming speech communication data or other incoming communication data similar thereto to the video and audio being reproduced, which is received by the mobile terminal  200 , and the like, by superimposing such displays on a display signal from the video processor  131 , on the basis of a data signal supplied from the signal processor  113 , and/or a control signal (control command) supplied from the controller  150 . 
         [0055]    The display processor  133  adjusts color, brightness, sharpness, contrast, or other image qualities of the received video signal on the basis of control by the controller  150 , for example. The display processor  133  supplies the display  134  with the video signal subjected to image quality adjusting. The display  134  displays video on the basis of the supplied video signal. 
         [0056]    Further, the display processor  133  superimposes a display signal from the video processor  131  subjected to the image quality adjusting on the OSD signal from the OSD processor  132 , and supplies the superimposed signal to the display  1341 . 
         [0057]    The display  134  includes a liquid crystal display panel including a plurality of pixels arranged in a matrix pattern and a liquid crystal display device including a backlight which illuminates the liquid crystal panel, for example. The display  134  displays video on the basis of the video signal supplied from the display processor  133 .

Further, the image receiving device  100  may be configured to include an output terminal which outputs an audio signal, in place of the speaker  122 . Moreover, the video processing apparatus  100  may be configured to include an output terminal which outputs a digital video signal and a digital speech signal. 
         [0059]    The controller  150  functions as control means for controlling an operation of each element of the image receiving device  100 . The controller  150  includes a CPU  151 , a ROM  152 , a RAM  153 , an EEPROM (non-volatile memory)  154 , and the like. The controller  150  performs a variety of processes on the basis of an operation signal supplied from the operation input module  161 . 
         [0060]    The CPU  151  includes a computing element, for example, which performs a variety of computing operations. The CPU  151  embodies a variety of functions by performing programs stored in the ROM  152 , the EEPROM  154 , or the like. 
         [0061]    The ROM  152  stores programs for controlling the image receiving device  100 , programs for embodying a variety of functions, and the like. The CPU  151  activates the programs stored in the ROM  152  on the basis of the operation signal supplied from the operation input module  161 . Thereby, the controller  150  controls an operation of each element. 
         [0062]    The RAM  153  functions as a work memory of the CPU  151 . That is, the RAM  153  stores a result of computation by the CPU  151 , data read by the CPU  151 , and the like. 
         [0063]    The EEPROM  154  is a non-volatile memory which stores a variety of setting information, programs, and the like.

         [0066]    A touchpad includes a device capable of generating positional information on the basis of a capacitance sensor, a thermosensor, or other systems. When the image receiving device  100  comprises the display  134 , the operation input module  161  may be configured to include a touch panel formed integrally with the display  134 . 
         [0067]    The reception module  162  includes a sensor, for example, which receives an operation signal from the remote controller  163  supplied by an infrared (IR) system, for example. The reception module  162  supplies the controller  150  with the received signal. The controller  150  receives the signal supplied from the reception module  162 , amplifies the received signal, and decodes the original operation signal transmitted from the remote controller  163  by performing an analog-to-digital (A/D) conversion of the amplified signal. 
         [0068]    The remote controller  163  generates an operation signal on the basis of an operation input from the user. The remote controller  163  transmits the generated operation signal to the reception module  162  via infrared communications. The reception module  162  and the remote controller  163  may be configured to transmit and receive an operation signal via other wireless communications using radio waves (RF), for example.

         [0082]    The ROM  252  stores programs for controlling the mobile terminal  200 , programs for embodying a variety of functions, and the like. The CPU  251  activates the programs stored in the ROM  252  on the basis of an operation signal from the operation input module  264 . Thereby, the controller  250  controls an operation of each element. 
         [0083]    The RAM  253  functions as a work memory of the CPU  251 . That is, the RAM  253  stores a result of computation by the CPU  251 , data read by the CPU  251 , and the like. 
         [0084]    The non-volatile memory  254  is a non-volatile memory configured to store a variety of setting information, programs, and the like. 
         [0085]    The controller  250  is capable of generating a video signal to be displayed on a variety of screens, for example, according to an application being executed by the CPU  251 , and causes the display  234  to display the generated video signal. The display  234  reproduces moving images (graphics), still images, or character information on the basis of the supplied moving image signal (video). Further, the controller  250  is capable of generating an audio signal to be reproduced, such as various kinds of speech, according to the application being executed by the CPU  251 , and causes the speaker  222  to output the generated speech signal. The speaker  222  reproduces sound (acoustic sound/speech) on the basis of a supplied audio signal (audio). 
         [0086]    The microphone  223  collects sound in the periphery of the mobile terminal  200 , and generates an acoustic signal. The acoustic signal is converted into acoustic data by the control module  250  after A/D conversion, and is temporarily stored in the RAM  253 . The acoustic data is converted (reproduced) into speech/acoustic sound by the speaker  222 , after D/A conversion, as necessary. The acoustic data is used as a control command in a speech recognition process after A/D conversion. 
         [0087]    The display  234  includes, for example, a liquid crystal display panel including a plurality of pixels arranged in a matrix pattern and a liquid crystal display device including a backlight which illuminates the liquid crystal panel. The display  234  displays video on the basis of a video signal. 
         [0088]    The touch sensor  235  is a device configured to generate positional information on the basis of a capacitance sensor, a thermo-sensor, or other systems. The touch sensor  235  is provided integrally with the display  234 , for example. Thereby, the touch sensor  235  is capable of generating an operation signal on the basis of an operation on a screen displayed on the display  234  and supplying the generated operation signal to the controller  250 . 
         [0089]    The operation input module  264  includes a key which generates an operation signal in response to an operation input from the user, for example. The operation input module  264  includes a volume adjustment key for adjusting the volume, a brightness adjustment key for adjusting the display brightness of the display  234 , a power key for switching (turning on/off) the power states of the mobile terminal  200 , and the like. The operation input module  264  may further comprise a trackball, for example, which causes the mobile terminal  200  to perform a variety of selection operations. The operation input module  264  generates an operation signal according to an operation of the key, and supplies the controller  250  with the operation signal. 
         [0090]    The operation input module  264  may be configured to receive an operation signal from a keyboard, a mouse, or other input devices capable of generating an operation signal. For example, when the mobile terminal  200  includes a USB terminal or a module which embodies a Bluetooth (registered trademark) process, the operation input module  264  receives an operation signal from an input device connected via USB or Bluetooth, and supplies the received operation signal to the controller  250 . 
         [0091]    The communication module  271  is capable of performing communications with other devices on the network  400  via the wireless communication terminal  300 , using a LAN or a wireless LAN. Further, the communication module  271  is capable of performing communications with other devices on the network  400  via a portable telephone network. Thereby, the mobile terminal  200  is capable of performing communications with other devices connected to the wireless communication terminal  300 . For example, the mobile terminal  200  is capable of acquiring moving images, pictures, music data, and web content recorded in devices on the network  400  via the communication module  271  and reproducing the acquired content. 
         [0092]    The MHL processor  273  is an interface which performs communications on the basis of the MHL standard. The MHL processor  273  performs signal processing on the basis of the MHL standard. The MHL processor  273  includes a USB terminal, not shown, to which an MHL cable can be connected. 
         [0093]    The mobile terminal  200  is capable of receiving a stream output from a device (source apparatus) connected to the USB terminal of the MHL processor  273 , and reproducing the received stream. Further, the mobile terminal  200  is capable of outputting a stream to a device (sink apparatus) connected to the USB terminal of the MHL processor  273 . 
         [0094]    Moreover, the MHL processor  273  is capable of generating a stream by superimposing a video signal to be displayed on a speech signal to be reproduced. That is, the MHL processor  273  is capable of generating a stream including video to be displayed on the display  234  and audio to be output from the speaker  222 . 
         [0095]    For example, the controller  250  supplies the MHL processor  273  with a video signal to be displayed and an audio signal to be reproduced, when an MHL cable is connected to the USB terminal of the MHL processor  273  and the mobile terminal  200  operates as a source apparatus. The MHL processor  273  is capable of generating a stream in a variety of formats (for example, 1080i and 60 Hz) using the video signal to be displayed and the audio signal to be reproduced. That is, the mobile terminal  200  is capable of converting a display screen to be displayed on the display  234  and audio to be reproduced by the speaker  222  into a stream. The controller  250  is capable of outputting the generated stream to the sink apparatus connected to the USB terminal. 
         [0096]    The mobile terminal  200  further comprises a power-supply  290 . The power-supply  290  includes a battery  292 , and a terminal (such as a DC jack) for connecting to an adaptor which receives power from a commercial power source, for example. The power-supply  290  charges the battery  292  with the power received from the commercial power source. Further, the power-supply  290  supplies each element of the mobile terminal  200  with the power stored in the battery  292 . 
         [0097]    The storage  274  includes a hard disk drive (HDD), a solid-state drive (SSD), a semiconductor memory, and the like. The storage  274  is capable of storing content such as programs, applications, moving images that are executed by the CPU  251  of the controller  250 , a variety of data, and the like. 
         [0098]      FIG. 4  is an exemplary diagram illustrating mutual communications between the electronic devices based on the MHL standard. In  FIG. 4 , the mobile terminal  200  is a source apparatus, and the image receiving device  100  is a sink apparatus, by way of example. 
         [0099]    The MHL processor  273  of the mobile terminal  200  includes a transmitter  276  and a receiver, not shown. The MHL processor  175  of the image receiving device  100  includes a transmitter (not shown) and a receiver  176 . 
         [0100]    The transmitter  276  and the receiver  176  are connected via the MHL cable  10 . 
         [0101]    When a Micro-USB terminal is applied as a connector at the time of implementation, the MHL cable is formed of the following 5 lines: a VBUS (power) line; an MHL− (differential pair [− (minus)] line; an MHL+ (differential pair [+ (plus)] line; a CBUS (control signal) line, and a GND (ground) line. 
         [0102]    The VBUS line supplies power from the sink apparatus to the source apparatus (functions as a power line). That is, in the connection of  FIG. 4 , the sink apparatus (power supplying source (image receiving device  100 )) supplies the source apparatus (mobile terminal  200 ) with power of +5V via the VBUS line. Thereby, the sink apparatus is capable of operating using the power supplied from the sink apparatus (via the VBUS line). The mobile terminal  200  as the source apparatus operates using power supplied from the battery  292 , during independent operation. When the mobile terminal  200  is connected to the sink apparatus via the MHL cable  10 , on the other hand, the battery  292  can be charged with the power supplied via the VBUS line from the sink apparatus. 
         [0103]    The CBUS line is used for bi-directionally transmitting a Display Data Channel (DDC) command, an MHL sideband channel (MSC) command, or an arbitrary control command(s) corresponding to application(s), for example. 
         [0104]    A DDC command is used for reading of data (information) stored in extended display identification data (EDID), which is information set in advance for notifying the counterpart apparatus of a specification (display ability) in a display, and recognition of High-bandwidth Digital Content Protection (HDCP), which is a system for encrypting a signal transmitted between the apparatuses, for example. 
         [0105]    An MSC command is used for, for example, reading/writing a variety of resistors, transmitting MHL-compatible information and the like in an application stored in the counterpart device (cooperating device), notifying the image receiving device  100  of an incoming call when the mobile terminal receives the incoming call, and the like. That is, the MSC command can by the image receiving device  100  to read MHL-compatible information of the application stored in the mobile terminal  200 , activate the application, make an incoming call notification (notification of an incoming call), and the like. 
         [0106]    As described above, the image receiving device  100  as a sink apparatus outputs a predetermined control command, MHL-compatible information, and the like to the mobile terminal  200  as a source apparatus via the CBUS line. Thereby, the mobile terminal  200  is capable of performing a variety of operations in accordance with a received command (when compatible with MHL). 
         [0107]    That is, the mobile terminal  200  (source apparatus) transmits a DDC command to the image receiving device  100  (sink apparatus), thereby performing HDCP recognition between the source apparatus and the sink apparatus and reading EDID from the sink apparatus. Further, the image receiving device  100  and the mobile terminal  200  transmit and receive a key, for example, in a procedure compliant with HDCP, and perform mutual recognition. 
         [0108]    When the source apparatus (mobile terminal  200 ) and the sink apparatus (image receiving device  100 ) are recognized by each other, the source apparatus and the sink apparatus are capable of transmitting and receiving encrypted signals to and from each other. The mobile terminal  200  reads the EDID from the image receiving device  100  in the midst of HDCP recognition with the image receiving device  100 . Reading (acquisition) of the EDID may be performed at independent timing different from that of HDCP recognition. 
         [0109]    The mobile terminal  200  analyzes the EDID acquired from the image receiving device  100 , and recognizes display information indicating a format including a resolution, a color depth, a transmission frequency, and the like that can be processed by the image receiving device  100 . The mobile terminal  200  generates a stream in a format including a resolution, a color depth, a transmission frequency, and the like that can be processed by the image receiving device  100 . 
         [0110]    The MHL+ and the MHL− are lines for transmitting data. The two lines of MHL+ and the MHL− function as a twist pair. For example, the MHL+ and the MHL− function as a transition minimized differential signaling (TMDS) channel which transmits data in the TMDS system. Further, the MHL+ and the MHL− are capable of transmitting a synchronization signal (MHL clock) in the TMDS system. 
         [0111]    For example, the mobile terminal  200  is capable of outputting a stream to the image receiving device  100  via the TMDS channel. That is, the mobile terminal  200  which functions as the source apparatus is capable of transmitting a stream obtained by converting video (display screen) to be displayed on the display  234  and the audio to be output from the speaker  222  to the image receiving device  100  as the sink apparatus. The image receiving device  100  receives the stream transmitted using the TMDS channel, performs signal processing of the received stream, and reproduces the stream. 
         [0112]      FIG. 5  is an exemplary diagram of the embodiment applied to mutual communications between the electronic apparatuses shown in  FIG. 4 . 
         [0113]    In the embodiment shown in  FIG. 5 , an MSC command is supplied from the image receiving device  100  to the mobile terminal  200  via the CBUS line. Further, names of applications stored in the mobile terminal  200  (and MHL-compatible information of each application) can be read (acquired) from the image receiving device  100 . It is to be noted that the HDCP recognition and EDID acquisition described with reference to  FIG. 4  have been completed before the control command (MSC command) is supplied (transmitted) and the MHL-compatible information is read (acquired). 
         [0114]    The owner of the portable terminal (source apparatus)  200  is capable of connecting the mobile terminal  200  (electrically) to the sink apparatus  100  connected via the MHL cable  10  merely for the purpose of charging the battery of the mobile terminal  200 . 
         [0115]    In terms of specifications at the time of MHL connection, control can be performed in a manner similar to that of the HDMI-Consumer Electronics Control (CEC) standard. Accordingly, when the mobile terminal  200  is connected to the image receiving device  100  merely for the purpose of charging the battery, an application being activated or video being reproduced in the mobile terminal  200  is displayed on the screen of the image receiving device  100 , regardless of the intention of the owner (user). 
         [0116]    Under such backgrounds, the present embodiment is configured such that settings as to whether to display, in the image receiving device  100 , an application being activated or video being reproduced in the mobile terminal  200 , when the mobile terminal  200  is connected to the image receiving device  100  via an MHL cable, can be made from a setting screen (screen display) which will be described with reference to  FIGS. 6-11  (and  FIGS. 18-23 ). 
         [0117]      FIG. 6  illustrates an example in which video or the like being displayed in the mobile terminal  200  is suppressed from being displayed on the screen of the image receiving device  100  regardless of the intention of the owner (user), when the mobile terminal  200  is connected to the image receiving device  100  via the MHL cable  10 . In this example, an MHL operation setting screen  521  is displayed in an image display  501  being displayed on the image receiving device  100 . That is, the screen  501  shown in  FIG. 6  displays an MHL operation setting (auto-menu) screen  521  including a “Charge” button (bar)  523  via which a selection input (operation instruction via the remote controller  163 ) can be made for the purpose of charging the connected mobile terminal  200 , and a “View video or photos” button (bar)  525  via which a selection input (operation instruction) can be made for the purpose of displaying video or the like being displayed in the mobile terminal  200 . 
         [0118]    That is, when the image receiving device  100  has detected that the mobile terminal  200  is connected via MHL, the image receiving device  100  displays the “Charge” button  523  and the “View video or photos” button  525  as the operation setting (auto-menu) screen  521  on the screen  501  being displayed at that point in time, and maintains (displays) a focus movement (remote control operation) by the remote controller  163  and a standby state waiting for input of an operation instruction by “Enter” button (input of a control command corresponding to “Enter”), for example, for a predetermined period of time. 
         [0119]    When a selection input is made with the “Charge” button (item name)  523  in the operation setting (auto-menu) screen  521  or the “View video or photos” button (item name)  525 , an operation corresponding to each item, which will be described with reference to  FIG. 12 , is performed. 
         [0120]    An operation instruction by “Enter” button (input of a control command corresponding to “Enter” button) or the like may be assigned to one of a “Blue” button  531 , a “Red” button  533 , a “Green” button  535 , and a “Yellow” button  537 , which are provided at predetermined positions in the screen display  501 , correspond to a “Blue” key, a “Red” key, a “Green” key, and a “Yellow” key provided on the remote controller  163 , respectively, and are configured to prompt the user to perform a key operation for a control input corresponding to a predetermined command set in the key of each color in each screen display. For example, when an output of a control command corresponding to “Enter” command is assigned to the “Yellow” button  537 , the “Enter” command can be output by operating the “Yellow” key on the remote controller  163 . 
         [0121]    A screen similar to that of the operation setting (auto-menu) screen  521  is also displayed in a display of the mobile terminal  200 , as exemplified in  FIG. 18 . Therefore, the owner (user) of the mobile terminal  200  is capable of making a selection input directly from the “Charge” button  223  or the “View video or photos” button  225  displayed on the display of the mobile terminal  200 . 
         [0122]    When the device  200  connected to the image receiving device  100  is embodied as a pair of headphones, or the like, which does not include an output module (for outputting video and speech) for use as the source apparatus and is not intended for outputting video or speech, display of the operation setting (auto-menu) screen ( 521 ) shown in  FIG. 6  and an operation setting screen ( 221 ) shown in  FIG. 18  can be omitted. That is, at the point in time when it is detected that the device  200  connected to the image receiving device  100  is a device not intended for output purpose, a charging operation may be started. It is possible to easily detect that the device  200  is not intended for output purpose on the basis of information unique to the device, such as a media access control (MAC) address. 
         [0123]    Whether to display the operation setting (auto-menu) screen shown in  FIG. 6  or not, i.e., whether to activate an auto-menu in the MHL-connected device or not can be set on an MHL connection setting screen shown in  FIGS. 7 and 19 . When an arbitrary selection input is made from each of a plurality of buttons that will be described below, an operation corresponding to each item that will be described with reference to  FIG. 13  is executed. 
         [0124]    An MHL connection setting screen  551  shown in  FIG. 7  includes an auto-menu display setting button  553 , an output setting button  555 , and an external operation setting button  557 , for example. The functions of the buttons, which are shown as a list in  FIG. 13 , will be described below. A screen similar to the MHL connection setting screen  551  is also displayed in the display of the mobile terminal  200 , as exemplified in  FIG. 19 . Therefore, the owner (user) of the mobile terminal  200  is capable of directly making a selection input from each button displayed on the display of the mobile terminal  200 . 
         [0125]    The auto-menu display setting button  553  is used for setting whether to display the [MHL operation setting (auto-menu)] screen shown in  FIG. 6 , and when a “Display” button  553  is selected, an [auto-menu display setting] screen  561 , which will be described below with reference to  FIG. 8 , is displayed. That is, when the “Display” button  563  is selected in  FIG. 8 , activation of the auto-menu described with reference to  FIG. 6  is set, and the MHL operation screen  521  shown in  FIG. 6  is displayed whenever the device (mobile device)  200  is connected to the image receiving device  100  via MHL. Therefore, when a “Do not display” button  565  is selected, even when the device (mobile device)  200  is connected to the image receiving device  100  via MHL, the MHL operation screen  521  (shown in  FIG. 6 ) is not displayed. A screen similar to the auto-menu display setting screen  561  is also displayed in the display of the mobile terminal  200 , as exemplified in  FIG. 20 . Therefore, the owner (user) of the mobile terminal  200  is capable of making a selection input directly from each button displayed on the display of the mobile terminal  200 . When an arbitrary selection input is made from each of a plurality of buttons that will be described below, an operation corresponding to each of a plurality of items that will be described with reference to  FIG. 14  is performed. 
         [0126]    An output setting button  555  displays an output setting screen  571 , which will be described below with reference to  FIG. 9 . That is, when an “Output video and speech” button  573  is selected in  FIG. 9 , the “View video or photos” button  525  defined by the auto-menu of the MHL operation screen  521  described with reference to  FIG. 6  is displayed via MHL whenever the device (mobile device)  200  is connected to the image receiving device  100 . A screen similar to the output setting screen  571  is displayed in the display of the mobile terminal  200 , as exemplified in  FIG. 21 . Therefore, the owner (user) of the mobile terminal  200  is capable of making a selection input directly from each button displayed on the display of the mobile terminal  200 . When an arbitrary selection input is made from each of a plurality of buttons that will be described below, an operation corresponding to each of a plurality of items that will be described with reference to  FIG. 15  is performed. In that case, it is possible to set whether to display the above-described auto-menu (whether to activate the auto-menu) or not, on the basis of the name and the number of the device or the name of the connection device connected to an arbitrary MHL device. 
         [0127]    When a “Do not output video or speech” button  575  is selected, even when the device (mobile device)  200  is connected to the image receiving device  100  via MHL, the MHL operation screen  521  (shown in  FIG. 6 ) is not displayed. In the example of  FIG. 9 , the “Output video and speech” button  573  and the “Do not output video or speech” button  575  are displayed (as OSD) as examples of output setting buttons  555 . Output settings, however, can be configured such that an “Output video but do not output speech” button or a “Do not output video but output speech” button are displayed and a corresponding control input is received (processing is performed in accordance with a control input). It is also possible to display checkboxes, radio buttons, or the like, which allow the user to set whether to output or not each of video and speech individually, receive a corresponding control input, and perform processing in accordance with the control input. 
         [0128]    An external operation setting button  557  displays an external operation setting screen  591 , which will be described below with reference to  FIG. 11 . That is, when an “Output video and speech” button  593  is selected in  FIG. 11 , video or speech being reproduced by the mobile terminal  200  or an incoming call indication indicating receipt of an incoming call (such as an image by which the caller can be specified) is displayed whenever the device (mobile device)  200  connected to the image receiving device  100  via MHL is activated by a certain factor, for example, by being operated (by the user) or receiving an incoming call. A screen similar to the external operation setting screen  591  is also displayed in the display of the mobile terminal  200 , as exemplified in  FIG. 23 . Therefore, the owner (user) of the mobile terminal  200  is capable of making a selection input directly from each button displayed on the display of the mobile terminal  200 . When an arbitrary selection input is made from each of a plurality of buttons that will be described below, an operation corresponding to each of a plurality of items that will be described with reference to  FIG. 17  is performed. When a “Do not output video or speech” button  595  is selected, video or speech being reproduced by the device (mobile device)  200  or an incoming call indication is not displayed when the device (mobile device)  200  connected to the image receiving device  100  is operated (by the user), receives an incoming call, or the like. 
         [0129]      FIG. 10  relates to settings of each device when two or more MHL devices are provided in the image receiving device  100 . For example, when two MHL devices are provided, the “Description” shown in  FIG. 16  is displayed at predetermined timing, according to the number of devices, for which a plurality of MHL-compatible devices are provided in the image receiving device  100 . Further, a screen similar to the MHL device setting screen  581  is also displayed in the display of the mobile terminal  200 , as exemplified in  FIG. 22 . Therefore, the owner (user) of the mobile terminal  200  is capable of making a selection input directly from each button displayed on the display of the mobile terminal  200 . When the “Do not output video or speech” button  595  is selected, the video or speech being reproduced by the device (mobile device)  200  connected to the image receiving device  100  or an incoming call indication is not displayed when the device (mobile device)  200  is operated (by the user), receives an incoming call, or the like. 
         [0130]      FIG. 24  illustrates settings for displaying, in the image receiving device  100 , of an application being activated and video being reproduced on the side of the mobile terminal  200  when the mobile terminal  200  shown in  FIG. 6  is connected to the image receiving device  100  via an MHL cable using the auto-menu shown in  FIG. 7 , in terms of software. 
         [0131]    When the mobile terminal  200  is connected to the image receiving device  100  via an MHL cable [ 101 ], it is detected that display settings (auto-menu) have been made [ 102 ]. 
         [0132]    When the display settings (auto-menu) have been made [ 102 -YES], (selection of) charging is detected [ 103 ]. 
         [0133]    When charging is selected [ 103 -YES], “Do not display” is set, in which an application being activated or video being reproduced (and sound [audio] being reproduced) on the side of the mobile terminal  200  is not displayed on the side of the image receiving device  100  [ 104 ]. 
         [0134]    When charging is not selected [ 103 -NO], it is detected that the device (mobile terminal)  200  is capable of outputting video/sound (includes an output device) [ 105 ]. 
         [0135]    When the device (mobile terminal)  200  is a device not including an output device for outputting video/sound [ 105 -NO], it is determined that (selection of) charging has been made. That is, an output of a display or the like is not displayed [ 104 ]. 
         [0136]    When the device (mobile terminal)  200  is a device capable of outputting video/sound [ 105 -YES], the mobile terminal  200  displays video being reproduced in or outputs an acoustic output to the image receiving device  100  [ 106 ]. 
         [0137]    While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the invention. Indeed, the novel embodiments described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions and changes in the form of the embodiments. The accompanying claims and their equivalents are intended to cover such forms or modifications as would fall within the scope and spirit of the invention. 
         [0138]    That is, according to the embodiment, it is possible to add “Set, in the sink apparatus (an output device or an image receiving device such as a TV), whether to output video being displayed by the source apparatus when the sink apparatus is connected to the source apparatus (such as a smartphone) via MHL”. Therefore, when a mobile terminal is connected to an image receiving device, it is possible to suppress an application being activated or video and speech output being reproduced in the mobile terminal from being output or reproduced without the intention of the owner (user) (it is possible to set an operation intended by the user at the time of connection). 
         [0139]    Further, according to an embodiment, when an external device (source apparatus/smartphone) connected to an image receiving device is operated, it is possible to set whether to output video and speech of the external device (or not), and hence user-friendliness is improved. 
         [0140]    Moreover, according to an embodiment, it is possible to suppress video and information of the source apparatus connected for the purpose of charging the battery, for example, from being immediately displayed in the sink apparatus. 
         [0141]    In order to achieve the embodiment, the control module detects that power is supplied to a connected device (a connected device is charged) (by identifying (the type of) the mobile terminal on the basis of a MAC address). 
         [0142]    Further, in order to achieve the embodiment, the control module receives a control instruction for not displaying the input video from a control instruction input module (button) displayed on the display (by allowing the user to select or determine a button) via a remote controller.
