Description

  The present invention relates to a multi-link display system suitable for viewing other related images such as more detailed related information near or at the viewer's hand while viewing images on a large television set in the living room. .

Recently, with the advancement of digital technology and information communication technology, there are increasing opportunities to view “screens in which images and characters are mixed (screens including images and characters)”.
For example, if you receive a data broadcast that multiplexes data related to the program content and sends it to a personal computer using a gap in the radio waves of a TV broadcast, “Mixed screen” is displayed or “when a“ window ”-like child screen is displayed in the parent screen” occurs.
In addition, TVs equipped with a “picture-in-picture (PIP)” function that displays a small screen on a large screen are on the market. When watching on a television with this PIP function, for example, it is powerful on a large screen. There are cases where detailed information related to the video is displayed on a small screen, which is also displayed in the “screen with a mixture of images and characters” and the “small screen in the large screen (parent screen)”. This is a type of “when a screen (child screen) is displayed”.
In addition, “Internet TV” that allows users to browse Internet homepages on TV has recently been put on the market. The main feature of this Internet home page is that it can be instantly switched to the linked home page. Most of the information on the homepage is "screen with mixed images and text".
As described above, recently, a “screen with mixed images and characters” placed in the living room (living room) and a screen (picture with a small screen (child screen) displayed in the large screen (parent screen))・ In-picture) ”and Internet homepages are increasing.

  Traditionally, the “living culture” (viewed in a family room) viewed by the viewer about 2 to 3 meters away from the living room, and the viewer watches from a distance of 30 cm on the desk in the office or study. It has been said that it cannot be easily integrated with the personal computer of "Study culture" (which is a personal tool). In the same context, it is said that TV is passively relaxed in the living room, and a personal computer is actively used in the study, private room, and workplace. Furthermore, in the same context, it is expressed that the TV is viewed with a back on the sofa in the living room (relaxed), and the computer is used with the back rolled up at the desk.

  In addition, depending on the contents of the Internet homepage, type A is suitable for viewing on a large display system away from the viewer, and type suitable for viewing on a relatively small display system near or at hand to the viewer. There is a thing of B. When the home pages are linked one after another, the type A and the type B appear one after another at random. For this reason, it is difficult to view type B information when viewed only on the stationary television. On the other hand, when viewing only with the personal computer, type A information cannot be fully enjoyed (for example, since personal computers cannot view type A information with a large number of family members, etc.). As described above, there is a problem that viewers are not easy to use in various respects even with only a stationary television or only with a personal computer.

  In addition, when watching live broadcasts of group sports such as soccer, theater broadcasts from theaters, concert broadcasts of music performance groups, etc. on large TVs in the living room, You want to track and watch the face of only one player, one actor in the theater, and one member in the music performance group (if you are scolding that one person as a fan) is there. However, since a large TV set in the living room is shared and enjoyed by the entire family, it is not possible to give a single person's face to the large TV set by giving priority to the preferences of only one person. Because it ’s annoying to other members.)

  Also, when a family member is watching a similar broadcast program on a stationary TV in the living room, even if one member of the family wants to see the profile of a player or actor, Displaying a profile as a “sub-screen” would be annoying to other families. This is because, when using a parent-child two-screen TV (television receiver), displaying the “window” -like “sub-screen” in the “parent screen” is concentrated on the “parent screen”. This is because the “sub-screen” becomes an obstacle to concentrate on viewing the “parent screen”. For this reason, even if one member of the family wants to see the profile of a player or actor, there is a problem that it is difficult for other families to do so.

  In addition, for example, information related to the contents of the screen displayed on a large display system placed at a distance of 2 to 3 m from the viewer (more detailed information, other related information, a part of the screen is enlarged) Video to be displayed, video to enlarge a specific person on the screen, video captured at other camera angles, information related to the time axis (for example, still images and repeat playback at a point just before the current time) The image) is preferably viewed at or near the viewer.

It is an object of the present invention to provide a small handheld display at or near a hand while a viewer views different images on two screens of a stationary large display device with a two-screen display function located at a relatively distant position. The device allows the user to easily view the small screen image of the two screens of the stationary large-sized display device, and easily displays the display content of the stationary large-sized display device by simply viewing the display content of the small-sized display device at hand. To be able to know.

In 3.1 and 2, the linkage means transmits a predetermined signal to the stationary large-sized display device, so that "information related to the display content of the stationary large-sized display device" is obtained from the stationary large-sized display device. The portable large-sized display device transmits "information related to the display content of the stationary large-sized display device" based on a predetermined signal from the cooperation means. , Which is wirelessly transmitted to the small handheld display device, and the small handheld display device receives and displays the "related information" transmitted from the stationary large display device. A multi-linkage display system characterized by that.
In 4.1 and 2, the cooperation unit transmits a predetermined signal to the small handheld display device, thereby receiving the small handheld display device from the “communication satellite (CS)” received by the small handheld display device. Based on "information sent by radio waves or radio waves for terrestrial broadcasting or broadcasting satellite (BS), by cable for cable television (CATV) broadcasting, or by communication lines used for the Internet" And displaying information related to the display content of the stationary large-sized display device.
5.1, 2, the cooperation means is “by a radio wave from a communication satellite (CS) or a radio wave from a terrestrial broadcasting station or a broadcasting satellite (BS), by a cable for a cable television (CATV) broadcast. Or a server on a network (including a home server) for receiving “information sent via a communication line used for the Internet or the like” and recording or processing the information. Is a system that receives and displays information from the server, and displays the information in cooperation with each other.
In 6.1 and 2, the cooperation unit is configured to communicate with a first transmission control unit for transmitting a predetermined program and other information from a predetermined recording medium or recording device to the stationary large-sized display device. Second transmission control means for causing the local small display device to transmit information related to the display content of the stationary large display device via a network or from a predetermined recording medium or recording device, This is a multi-link display system.

A large-sized stationary display device such as a wall-mounted television placed in the living room where the present invention was created is suitable for sharing with the entire family (viewing with family members). It is suitable for watching TV programs from a distance of about 2 to 3 meters. On the other hand, small portable display devices such as personal computers (personal computers) and PDAs (portable information terminals) are suitable for personal use by individuals ("personal media" used by individuals). It is suitable for the viewer to see text / image information such as newspaper information at or near his or her hand.

For this reason, the inventor of the present invention is inappropriate for the contents displayed in a large stationary display device placed in the living room and a small (particularly portable) display device used by an individual at hand. I thought there was. In other words, the large display device placed in the living room is suitable for displaying the contents of a conventional television program and the like suitable for all the family members to enjoy and watching at a distance of about 2 to 3 m. On the other hand, a small (especially portable) display device that is placed at the viewer's hand is suitable for displaying information that the viewer uses personally (not for the entire family). Therefore, the present inventor considered that a “multiple linkage display system” capable of exhibiting the characteristics of both would be required in the future.
Specifically, the functions of a conventional TV are divided into a “master unit” (a large stationary TV set 2 to 3 m away from the viewer in the living room) and a “slave unit” (viewer It is separated in hardware from a small television that is handy, preferably portable. Then, for example, a parent screen and a child screen of a television having a conventional PIP (picture-in-picture, parent-child two-screen display) function are assigned to the parent device and the child device, respectively. This is because as long as the conventional TV screen of the PIP function is viewed, the screen displayed on the sub-screen has a TV shopping order screen, sports player data, and the like. Therefore, it is desirable to display such sub-screen data on the “slave unit” at hand of the viewer.

Although not “the invention itself described in the claims of the present application”, the contents of the invention disclosed in the present specification The multi-link display system according to the present invention is the contents of the display screen of the stationary large display device and the small display at hand. The contents of the display screen of the device are linked to each other, and the stationary large display device and the handy small display device share the contents and roles of the screen display with each other, for example, It is as follows.
1. A relatively large screen display unit for displaying program content mainly composed of images based on “information transmitted by television broadcasting”, which is used by being placed relatively far from the place where the viewer is. A small and small display having a large and stationary type large display device (parent device) having a relatively small screen display unit for displaying characters or images. An apparatus (slave unit), and linkage means for displaying on the screen display unit of the slave unit the content linked to / linked in real time or almost in real time with the display content of the master unit. Multiple linkage display system .

In the present invention, the term “stationary type” is used to mean “cannot be moved easily (because it is heavy or fixed due to housing) (non-portable type)” . This "stationary type" includes a type that is placed on a floor such as a living room, a wall-hanging type that is hung on an inner wall such as a living room, a type that is provided on a ceiling such as a living room or a bedroom, or a ceiling and wall in a living room or bedroom, etc. This includes a type that can be moved between the floor and the floor .

In the present invention, it is desirable that the handset is of a portable type that can be freely carried by a viewer. However, the handset need not be “portable” as long as it can be used in the vicinity of the viewer or at hand . For example, the slave unit may be a display device built in a “table” (such as a table) used by the viewer. That is, the “child device” of the present invention includes a child device built in a table for four persons and the screen display portion of the child device exposed at the center of the table. According to the configuration in which the slave unit is built in such a table, for example, four members of the family can display on the screen display unit of the slave unit in the center of the table while watching the live broadcast program of the horse race on the stationary large television. The betting ticket purchase screen can be used to order a betting ticket online . In addition, while a family sits at a table and watches a program that introduces catalog-sold products on the screen of a stationary master unit, a screen for ordering products and electronic payment is displayed on the screen display of the slave unit provided on the table. For example, the user can display an order screen and pay for the product with electronic money .

Further, when the slave unit is built in the table or the like as described above, the connection between the slave unit and the master unit may be performed not by wireless but by wire. In other words, in the present invention, it is desirable in many cases that the slave unit cooperates with the master unit wirelessly. You may make it transmit to a subunit | mobile_unit by transmission .
That is, in the first aspect of the invention, it is desirable that the slave unit is wirelessly connected to the master unit. However, the slave unit and the master unit are not necessarily connected wirelessly. This is because a home server (data management computer) is installed in one home, and all the broadcast waves or information transmitted from an external communication network are once taken into this home server, This is because the home server may send (redistribute) information to the parent device and the child device, respectively, so that the parent device and the child device can display information linked to each other. In this case, the slave unit is connected to the home server by wireless or wired connection, and the master unit is also connected to the home server by wireless or wired connection. In other words, in the present invention, data can be directly exchanged between the parent device and the child device, but when using a home server, data is directly transferred between the parent device and the child device. Data may be exchanged via the home server without being exchanged.

  In the present invention, the “small slave” includes an HMD (bed mount display). In addition, this HMD supports the display on the viewer's head or face, such as glasses, goggles, and helmets.

  In the present invention, a plurality of slave units may be provided. For example, while four family members watch a single large-sized television in the living room, each of the four family members has a child unit at hand, and displays a screen with content according to their own preferences and wishes. It may be. Further, the slave table may be built in the table for the table, and the screen display unit of the slave unit may be exposed at the four portions corresponding to the positions where four persons sit on the upper surface of the table. In this case, a total of four screen display parts are formed on the table).

Further, in the present invention, the slave unit is a portable controller for transmitting / receiving power of a display device such as a television or switching a channel by transmitting an infrared signal or the like from a remote controller for the master unit. The device may be integrated with the device . That is, an input device for a viewer to input control information in order to turn on / off a power source of a display device such as a television or switch a channel, a transmission device for wirelessly transmitting the control information, and an image A display device for displaying and a receiving device for receiving video information from outside are configured as a “remote controller” provided in one housing (for example, a notebook-type or notebook-type information device). May be.

In the present invention, the above 1. "Information sent by TV broadcast", which is information indicating a program displayed by the parent device, is information sent by a TV broadcast radio wave such as digital satellite broadcast or terrestrial wave, CATV (cable television), that is, wired Information sent by TV broadcasting, information automatically distributed by Internet “push technology” and “broadcasting Internet”), continuously sent from the Internet homepage to the viewer's communication terminal accessing it It also includes information about live concerts such as coming concerts and concerts . In particular, in the present invention, a case where “information continuously transmitted from a television broadcasting station or an Internet broadcasting station” is displayed on the parent device is a typical case of its use.
In the present invention, “television” means “image or text is converted into a signal such as an electric signal or an optical signal, which is sent to the viewer side via radio waves or cables, and the viewer side Is a receiver or receiver for reproducing the image or characters based on a broadcasting / communication system for reproducing the image or characters.

That is, in the present invention, the above-mentioned “information transmitted by TV broadcasting” refers to radio waves (terrestrial TV radio waves and satellite TV radio waves) of TV broadcasts (terrestrial TV broadcasts and satellite digital TV broadcasts). Individual viewers from “Internet broadcasting stations” that use “push technology” on the Internet, including “TV BI (Vertical Blanking Interval)” used in “data broadcasting”. Refers to information that is automatically distributed (transmitted) to other communication terminals (computer terminals), programs that are continuously transmitted from the Internet site (homepage) to viewer terminals (for example, live broadcast video of concerts), etc. Yes .
The “push technology” of the Internet (also called “broadcast Internet” or “Internet broadcast”) means that information is actively viewed on the Internet without waiting for access from viewers. It is a mechanism for delivering to a user.

2. In 1 above, when the master unit displays a relatively large image on almost the entire display screen and displays a relatively small character on a part of the display screen, A multi-linkage display system in which a portion of characters displayed on the base unit is displayed relatively large on the screen display unit .
In the present invention, the slave unit has a parent-child screen display function, the character portion is displayed relatively large on the “parent screen” of the slave unit, and the above-mentioned “child screen” of the slave unit is displayed. You may make it display the same content as the display content of a main | base station.
Further, in the present invention, the “character part” is displayed relatively large on the screen of the slave unit, and the “background part” of the “character part” (the “character part” is displayed). As the “background screen”, the same content (such as a movie image) as the content displayed on the parent device may be displayed.
In this way, the viewer can know the display contents of the parent device only by looking at the screen of the child device.

In the present invention, the case where “a relatively small character is displayed on a part of the display screen” of the parent machine means, for example, a caption subtitle (telop) of a foreign movie or a translation of a conversation in an interview program with a foreigner. Subtitles (telops), text by teletext using gaps in TV radio waves, subtitles (telops) for notifying emergency information such as earthquakes and disasters in ordinary TV programs, and explanations of news incidents in news programs There are flips (signboards / boards displaying characters) used by commentators when performing.
In addition, “text broadcasting” in which text information is broadcast in the gaps between television waves has been started in Japan for 12 years. A TV with a built-in teletext receiver can watch subtitles. This subtitle broadcasting is currently being implemented in Japan. Also, not only television broadcasting but also radio FM broadcasting distributes character information and road traffic information by radio waves (so-called “visible radio”).
In addition, a service that superimposes and transmits digitized data signals in the gaps between TV waves (as in the case of the traditional “text broadcasting” of television that has been in practical use in Japan for 12 years, the gaps in the TV waves are used. "Data broadcasting", which is a "data multiplex broadcasting service" that sends data in this manner, has already been started by a plurality of companies.

If the content of flips (subtitles) and telops used in the above-mentioned news programs are transmitted as digital data that can be distinguished from other images (newscasters, commentator images, etc.), It is easy to display flips and telops large. However, if the flip or telop is mixed as the image and analog data, it is quite difficult to distinguish between the two. However, even in that case, if there is a technology (already developed) that automatically recognizes only the character part and converts it into character data (text data), it is possible to display only the character part on the slave unit. is there. Such a technique has already been developed.
In addition, the technology that automatically converts speech into text makes it possible to display the translated text in real time during an interview in a foreign language on a television . Of course, when an interview is conducted in Japanese, it is also possible to display subtitles in real time in Japanese , which is useful for hearing impaired people.

3. In the above 1, when the link unit is displaying an image, the link unit displays “information related to the image of the master unit on the Internet home page” on the screen display unit of the slave unit. A multi-linkage display system for displaying “related information” on the image of the parent device, such as “information” .
In the present invention, it is desirable that the master unit has a bidirectional (interactive) broadcasting / communication service function capable of providing information desired by a viewer.
Further, in the present invention, the slave unit is provided with a master-slave screen display function, and the above-mentioned “related information” is displayed on the “parent screen” of the slave unit, while the master unit is displayed on the “slave screen” of the slave unit. The same information as the display content may be displayed. In this way, the viewer can know the display contents of the parent device only by looking at the child device screen (parent screen and child screen).

The provision of the “related homepage information on the Internet” can be provided by browsing the homepage information linked on the Internet with a browser . It is also possible to use the “push technology” of the Internet or the data distribution using the “multicast technology” of the Internet.

4). In the above 1, the parent device has a parent-child screen display function (two-screen method or the like), and the cooperation unit displays the “before parent image” displayed relatively large by the parent device. When a relatively small “child screen” is simultaneously displayed in an open area such as “window” in the parent screen, the “child screen” of the parent device is displayed on the screen display unit of the child device. Is a multi-link display system that displays the contents of "
In the present invention, the slave unit is also provided with a master-slave screen display function, and the content of the “slave screen” of the master unit is displayed on the “master screen” of the slave unit while the “slave screen” of the slave unit is displayed. The contents of the “parent screen” of the parent device may be displayed as they are in the “sub-screen” . That is, in this case, the contents of the “parent screen” and the contents of the “child screen” of each of the parent device and the child device are reversed to each other. In this way, the viewer can know the contents of the parent device's parent screen at the same time by simply looking at the child device screens (parent screen and child screen) .

  According to the fourth invention, in a television (such as a two-screen television receiver) having a conventional picture-in-picture function (PIP function; parent-child screen display function), the child screen is a “window” (window). However, this small screen is displayed large on the handset at the viewer's hand so that the viewer can easily see it (displayed on the stationary TV by the conventional PIP function) The sub-screen has a stationary TV set about 2 to 3 meters away from the viewer, and the size of the sub-screen is so small that it is difficult for viewers (especially myopic) to see it clearly. There was a problem). In the fourth invention, since the “child screen” of the parent device can be displayed on the child device, the “child screen” of the parent device may continue to be displayed on the parent device. There is no inconvenience even if it is not continued. Therefore, according to the fourth aspect of the invention, it is not necessary to keep the “child screen” displayed on the parent device (from the time when the contents of the “child screen” of the parent device are displayed on the child device, Since the “child screen” may be erased from the parent device, there is no “window” on the parent device screen, and the entire screen of the parent device is easy for the viewer to see and easy to watch. Can be a thing. That is, when a sub-screen is displayed like a “window” in the main screen displayed on the display unit of one television by the conventional PIP function, the presence of the “window” indicates that the viewer However, according to the present invention, such a problem can be solved.

5). In the above 1, the cooperation means is a person displayed on the screen of the master unit on the screen display unit of the slave unit when the master unit displays a moving image including a plurality of persons. A multi-linkage display system that displays a relatively large “image of a specific person specified by a viewer” .
In the present invention, for example, a video obtained by imaging a plurality of people together and a video obtained by imaging each person are broadcast or transmitted together, and a “video obtained by imaging a plurality of people together” is displayed on the master unit. In this case, the “video of a specific person designated by the viewer” is displayed on the slave unit.
In the present invention, the child device is provided with a parent / child screen display function, and the child device's “parent screen” is displayed while displaying the above-mentioned “video of a specific person designated by the viewer”. The display contents of the parent device (“video obtained by capturing a plurality of people together”) may be displayed as they are on the “child screen”. In this way, the viewer can know the display contents of the parent device at the same time only by looking at the child device screen (parent screen and child screen).

6). In the above 1, the cooperation unit displays the video imaged at a certain camera angle among the video images obtained by imaging a certain target with a plurality of camera angles. Multiple linkage display that displays “video captured at other camera angle” different from the camera angle of the video displayed on the screen of the master unit on the screen display unit of the slave unit System .
In the present invention, for example, in “ multi-camera angle broadcasting / transmission ” that has already been performed in sports games such as baseball games, video from a certain camera angle is displayed on the screen display unit of the parent device. The image from another camera angle is simultaneously displayed on the screen display unit of the slave unit.
In the present invention, the slave unit has a master-slave screen display function, and the "master screen" of the slave unit is displayed with the above-mentioned "video taken from the camera / angle desired by the viewer" On the “child screen” of the slave unit, the display content of the master unit (for example, video captured from the camera angle selected by the television station) may be displayed as it is. In this way, the viewer can know the display contents of the parent device at the same time only by looking at the child device screen (parent screen and child screen).
One method for realizing the “multi-camera angle broadcasting” is to provide one program through a plurality of channels . For example, in a baseball or soccer broadcast, the camera is currently switched at the broadcast station, but if the video captured by each camera is streamed to a different channel, viewers can set their own channel. By switching, you can see each scene from the angle you want (camera angle).

7). In 1 above, when the master unit is displaying a certain moving image, the cooperation unit is a “part” of the image displayed by the master unit on the screen display unit of the slave unit and is viewed. A multi-linkage display system that displays a “part of an image” designated by a person relatively large .
In the present invention, for example, when an image in a base unit of a bitmap display (method for displaying information in units of dots) is displayed, a bitmap in a certain area (part of the screen) designated by the viewer is displayed. Only such an image is displayed in real time on the slave unit.
In the present invention, the slave unit has a master-slave screen display function, and the “parent screen” of the slave unit is displayed while displaying the above “part of the screen specified by the viewer”. The display contents of the parent device (the entire display screen of the parent device) may be displayed as they are on the “child screen”. In this way, the viewer can know the entire display contents of the parent device at the same time only by looking at the child device screen (parent screen and child screen).

8). In the above 1, the cooperation means, while the master unit is displaying a certain moving image, indicates to the slave unit “at the time point designated by the viewer” in the moving image displayed by the master unit. A multi-linked display system that displays “image” as “still image” .
According to the eighth aspect of the invention, an image showing “a person” in a moving image displayed on the master unit or a part thereof is displayed as a still image on the slave unit. In the present invention, for example, a moving image displayed on the parent device is recorded in real time on a recording device such as a hard disk or a DRAM (dynamic random access memory) provided in the parent device, the child device, or the home server. Then, based on an instruction from the viewer, an image at a certain time point is displayed as a still image on the slave unit.
In the present invention, the child device has a parent-child screen display function, and the “parent screen” of the child device is displayed in a large size while the “still image specified by the viewer” is displayed. The display contents of the master unit (moving images currently in progress) may be displayed as they are on the “sub-screen”. In this way, the viewer can know the display contents of the parent device at the same time only by looking at the child device screen (parent screen and child screen).

9. In the above 1, the cooperation unit is configured to display “after the time point designated by the viewer” in the moving image displayed by the parent device on the child device while the moving image is displayed on the parent device. Multi-linkage display system that plays back “moving images” .
In the ninth aspect of the invention, while the master unit is displaying the moving image, the entire moving image displayed on the master unit or a partial moving image of the screen is displayed on the child unit. Repeated (rewind / replay) is displayed on the machine. In the present invention, for example, a moving image displayed on the parent device is recorded in real time on a recording device such as a hard disk or a DRAM (dynamic random access memory) provided in the parent device, the child device, or the home server. Then , based on an instruction from the viewer, an image from a certain point in time is displayed on the slave unit so as to repeat (play) .
In the present invention, the child device has a parent-child screen display function, and the “parent screen” of the child device is displayed with the above-mentioned “ repeat moving image from the time point designated by the viewer ” large, You may make it display the display content (moving image in progress) of the said main unit as it is on the "sub-screen" of the sub unit. In this way, the viewer can know the display contents of the parent device at the same time only by looking at the child device screen (parent screen and child screen).

  In the above inventions 2 to 7, the screen having the parent device and the screen having the “data parent-child relationship (relation)” are displayed on the child device. On the other hand, the inventions of the above 8 and 9 are screens that have a “temporal or time-axis parent-child relationship (relation)” with the screen of the parent device (for example, a time delay with respect to the parent device screen). Screen) on the handset.

Reference numerals 21a, 22a, and 23a denote screen display units (comprised of LCD, organic EL (electro-neminescence), etc.) provided in the slave units 21, 22, and 23, respectively. 41, 42, and 43 are used for wireless transmission / reception with the wireless transmission / reception units 31, 32, and 33 of the parent device 20 (that is, between the parent device 20 and each of the child devices 21, 22, and 23). In order to transmit and receive signals between each other wirelessly, the wireless communication units are provided in the slave units 21, 22, and 23, respectively. In FIG. 1, reference numerals 51, 52, and 53 denote wireless transmission / reception units provided for wirelessly transmitting and receiving signals between the respective slave units 21, 22, and 23.
As described above, in the present invention, since the base unit 20 and the handset units 21, 22, and 23 can perform data communication with each other wirelessly, image data, character data, audio data can be exchanged between them. Such as content data and control signals can be transmitted and received mutually. Therefore, the display contents of the parent device 20 and the display contents of the child devices 21, 22, and 23 can be shared in real time with each other as desired by the viewer by a predetermined computer program. In other words, the contents of the display screen of the parent device and the contents of the child device display are linked in real time to each other while the parent device and the child device are linked to each other. The contents and roles to be displayed can be shared with each other.

As described above, according to the invention described in the claims of the present application, the viewer views different images on the two screens of the stationary large display device with the two-screen display function located at a relatively distant position. On the other hand, it is possible to easily view a small screen image in the two screens of the stationary large-sized display device with a small-sized display device at hand or in the vicinity thereof, and only display contents displayed on the small-sized display device at hand. As a result, it is possible to easily obtain the display contents of the stationary large display device .

Further, according to both the invention described in the claims of the present application and the invention disclosed in the entirety of the present specification (hereinafter sometimes referred to as “the present invention”) , for example, as shown below An effect can be obtained.
First
For example, (1) “part of the sub-screen in the screen where the sub-screen is displayed in the main screen”, (2) “part of the screen displayed on the base unit specified by the viewer”, (3) “Video of a specific person in the video of multiple people displayed on the master” or (4) “Image taken at a certain camera angle in the video taken with multi-camera angle” When the recorded video is displayed on the main unit, the video captured with a camera angle different from that video is displayed on the viewer's hand or nearby small display device (enlarged display). ) Can be seen easily for people with myopia, etc. (1) “Part of the sub-screen in the sub-screen where the sub-screen is displayed in the main screen”, (2) “Display on the main unit Part specified by the viewer in the displayed screen ”, (3)“ Specific person in the video of multiple people displayed on the parent device Or (4) When a video imaged at a certain camera angle in a video imaged at a multi-camera angle is displayed on the parent device, It is possible to clearly and clearly see “a video imaged at an angle”.
Second
Further, in the present invention, the slave unit is provided with a master-slave screen display function (two-screen method), and the screen display unit of the slave unit displays “the contents displayed on the master unit as described above (1) to (3)” If the same image as the screen of the parent device is displayed on the “child screen” of the child device while the “linked / related content” is displayed as the “parent screen”, the viewer will be able to It is very convenient because it is possible to grasp the display contents of the master unit simply by looking at the machine.
Third
Further, according to the present invention, in a television receiver or a personal computer having a conventional picture-in-picture function (PIP function, two-screen display function), the child screen is displayed as a “window” in the parent screen. Although it is open, this child screen is displayed large on the child device at hand of the viewer so that the viewer can easily see it (the child screen displayed on the stationary television by the conventional PIP function is In addition to the fact that the stationary TV is installed about 2 to 3 meters away from the viewer and the size of the child screen is small, there is a problem that it is difficult for viewers (especially myopic) to see clearly) Is.
In the present invention, since the “child screen” can be displayed on the slave unit, the “slave screen” may or may not be displayed on the master unit. Therefore, according to the present invention, it is not necessary to display the “child screen” on the parent device (there is no need to display the “child screen” like “window” on the parent device). An extra “window (sub-screen)” is eliminated on the screen, and the effect is obtained that the screen of the master unit can be easily viewed by the viewer and viewed by the viewer. That is, when displaying a sub-screen like a “window” in the main screen displayed on the display unit of one TV by the conventional PIP function, the presence of the “window” means that the viewer concentrates the main screen. However, this problem can be solved by the present invention.

Japanese Patent Publication No. 6-61390 “Parent-Child Electronic Game Device” (Applicant: Casio Computer) discloses the following device. “A large electronic game device and a small electronic game device are connected to execute a game of the small device on the large game device. Therefore, the child electronic game device is set in the parent electronic game device. The game can be enjoyed on a large screen with a large key and easy to see, and the game can be played on a child electronic game device, and the execution process can be displayed on the display surface of the parent electronic game device by transfer, Conversely, a game can be played on the parent electronic game device, and the execution process can be transferred and displayed on the display surface of the child electronic game device, and a plurality of child electronic game devices can be connected to a number of parent electronic game devices. In addition, as shown in FIG. 14 and FIG. 15 (fourth embodiment) of this gazette, two games with a parent electronic game device are possible. When playing a battle game with a child electronic game device connected, the player does not display the mine position set by himself / herself on the display device of the parent electronic game device and the display device of the child electronic game device of the opponent. It is displayed on the electronic game device for children. That is, it is possible to display only the position of the landmine set by the user that he / she does not want to show to his / her opponent only on his / her child electronic game device.
As described above, according to the above publication, when a battle game is played by connecting a parent electronic game device and two child electronic game devices, the position of the mine set by the player is the same as the display device of the parent electronic game device. Although it is not displayed on the display device of the opponent's child electronic game device, it is displayed on the child's electronic game device. That is, it is possible to display only the position of the landmine set by the user that he / she does not want to show to his / her opponent only on his / her child electronic game device.
As described above, in the above publication, “a technology that makes the display content of the child electronic game device slightly different from the parent electronic game device (the position of the land mine that you do not want to show to your opponent is displayed It is disclosed that only the device can display it).
However, the above publication is based on the premise of an electronic game device, and the display content of the child electronic game device is basically the same as the display content of the parent electronic game device. Exceptionally, it is recognized that the mine position set by the user that is not desired to be shown to the opponent can be displayed only on the child electronic game device.
This is described in the 8th to 16th lines of the right column (column 9) on page 6 of the above-mentioned gazette, "If the shell fired by your tank hits the opponent's tank, the main CPU 14 determines that, The CRT display device 3 and each of the child electronic game devices 6 and 6 are given and displayed with the opponent tank destruction data and their own scoring data. . That is, this description clearly shows that “the own score data added to the opponent tank destruction data” and the like are displayed in common on the parent electronic game device and the child electronic game device.
In other words, in the above publication, the display content of the parent electronic game device and the display content of the child electronic game device are basically always the same and common. The presence / absence of “the landmine position set by the user” may be slightly different between the display of the parent electronic game device and the display of the child electronic game device.
On the other hand, the present invention is premised on a “television” having a characteristic of “streaming a program based on information transmitted by television broadcasting (including via the Internet)” such as television radio waves. Information related to the display content of the “master unit” that is “TV” (related information that is fundamentally different from the display content of the master unit) is displayed on the “child screen” in the “parent screen” of the master unit ( Instead of the conventional parent-child two-screen system), the starting point (technical idea) is to display on the screen display unit of the “child device”.
As described above, in the device shown in the above publication, what is displayed on the “parent” electronic game device is a game screen (game screen that is read and displayed from a CD-ROM or ROM cassette). It is not a “program continuously played based on information sent by television broadcasting” like the “master” of the present invention.
Further, in the above publication, what is displayed on the child electronic game device is not only “same game scene and score data”, which is basically the same as the parent electronic game device and has the same contents as the present invention. It is basically different from the display contents of the main unit (if the image and text are different, the same image even if the target is different, the same target even if the camera angle is completely different), but the main unit It is not “information linked to or linked to the display content”.
In these respects, the above-mentioned publication and the present invention are completely different in their objects (television and game device), and their operational effects and technical ideas are also completely different.

  The best mode for carrying out the present invention is a mode as described in Example 1 below.

Next, FIG. 2 is a schematic diagram for explaining the first embodiment of the present invention mainly from the appearance, and FIG. 3 is a schematic block diagram for explaining the concept of the present embodiment. In FIG. 2, 1 is a master unit composed of a home-use large-sized television set in the living room, 1a is a screen display unit for displaying the screen of the television, 2 is connected to the master unit 1, and A receiving antenna 3 for receiving a signal by radio waves from a television station or an artificial satellite 3 is a transmitting / receiving unit for transmitting / receiving data to / from an external device by radio (for example, infrared rays).
In FIG. 2, 4 is a table (for use by a viewer in the family) approximately 2 to 3 m away from the parent device 1, and 5 is a small mobile phone placed on the table 4. 6a is a display unit for displaying the screen of the slave unit 5, and 6 is a support base for placing the slave unit 5 on the table 4. 5 is a transmitter / receiver for transmitting / receiving data to / from an external device by radio (for example, infrared rays), and 8 is a speaker for voice / sound output. In FIG. 2, 9 is a remote controller (remote controller) for inputting data such as characters or symbols, a program channel number, and a control signal such as a power ON / OFF signal. The remote controller 9 has a keyboard for inputting characters and a pointing device such as a mouse (not shown), a trackball (not shown), and a slice pad (not shown) for inputting positional information on the screen. A device (not shown) is provided. Reference numeral 10 denotes a transmission / reception unit for transmitting / receiving data to / from an external device by radio (for example, infrared rays). In this embodiment, the remote controller 9, the master unit 1, and the slave unit 5 can wirelessly transmit and receive signals between the three parties by the wireless transmission / reception units 3, 7, and 10. ing.

In this embodiment, only one slave unit (small display device) 5 is shown on the table 4, but this slave unit 5 can be individually held by all members of the family. In addition to homes, a single parent device 1 and a plurality of child devices 5 may be provided as a set in a certain room at a workplace, a public facility such as a library or an art museum .

Next, the operation of this embodiment will be described with reference to FIG.
(A) First, when image information and character information are mixedly mounted on the parent device 1, a case where character information is mainly displayed on the child device 5 at hand of the viewer will be described.
An example is now given to the case where the viewer wants to watch a certain program (in the following example, this program is assumed to be a live broadcast program of a sport game). Note that the master unit 1 of the present embodiment is a two-screen television (having a picture-in-picture function). In this case, the viewer operates the remote controller 9 at hand to select a favorite program, wirelessly transmits a control signal to the master unit 1 from the transmission / reception unit 10 provided in the remote control 9, and receives the control signal. A channel with a favorite program is selected from the antenna and displayed. In addition, the viewer operates the remote controller 9 to set the operation mode of the slave unit 5 to a mode corresponding to the request “largely display mainly the character information in the screen of the master unit 1”. Let ’s say.
Now, when the viewer instructs the output of a favorite player's profile while watching a sports game, the screen of the sports game is doubled (folded) in the large screen of the main unit 1. , The player profile screen is displayed. The display of this profile is also displayed on the display unit 5a of the handset 5 at or near the viewer (by the mode setting of the handset 5) at the same time that it is displayed on the base unit 1. Large display . For the viewer, the display of the profile is difficult to see from the distance of about 2 to 3 m (especially for myopic people) only by the display of the parent device 1, but the child device 5 is viewed. Because it is in the hands of the person, you can easily see the profile as if you were looking at a magazine or newspaper.

The player profile data to be displayed on the child device 5 can be displayed on the child device 5 by a method of wireless transmission from the parent device 1 to the child device 5, but other methods are also possible. . As another method, for example, the signal received by the receiving antenna 2 is directly transmitted to the parent device 1 and the child device 5 respectively, and the child device 5 receives the profile in the signal received by the receiving antenna 2. Alternatively, only a signal indicating “” may be selected and displayed in a large size.
As described above, in the present embodiment, the base unit 1 and the handset 5 cooperate with each other, so that the screen of the base unit 1 and the screen of the handset 5 are interlocked with each other, and display contents and roles are mutually related. It will be displayed while sharing.

  In the present embodiment, the player's profile is displayed relatively large on the slave unit 5 and the sport game displayed on the master unit 1 is displayed on the background portion of the profile of the slave unit 5. Also good. That is, when a sports game program is displayed on the master unit 1, the player profile is displayed in a small corner on the display unit of the master unit 1 and is difficult for the viewer to see. Therefore, in the present embodiment, the child profile 5 can be displayed in a large size, and the sports game program (contents displayed on the master device 1) can be displayed on the background.

FIG. 4 shows an example of the operation (A). In FIG. 4, 12 is a screen displayed on the parent device 1, and 13 is a screen displayed on the child device 5. A screen (foreign movie) is displayed on the screen 12 of the main unit 1, and a superimposed subtitle (a character string indicating the conversation contents of the movie characters) 12a is displayed in the lower part of the screen. It is displayed with tatami mats. However, since the caption portion is character information, there is a problem that it is difficult to see from the screen of the main unit 1 located at a position about 2 to 3 m away (especially for a nearsighted viewer). Therefore, in this embodiment, based on the radio signal from the master unit 1, the character information of the caption superimpose is enlarged and displayed on the screen 13 of the slave unit 5. Therefore, even a near-sighted person can read only the subtitles on the screen at hand by the handset 5 while viewing the Western movie on the large powerful screen of the base unit 1.
In this embodiment, in this case, the screen image of the slave unit 5 may be displayed with a large image displayed on the master unit 1 on the background while displaying a large caption. In this way, the viewer can conveniently grasp not only the display contents of the slave unit 5 but also the display contents of the master unit 1 only by looking at the slave unit 5.

In addition, when reading information from a video tape using a conventional analog recording method and viewing a movie, a signal in which subtitles and images are integrated in an analog manner is recorded on the video tape. It is difficult to extract only the subtitles and display them on the slave unit 5 (the same applies when watching a movie program with subtitle supervision in an analog television broadcast). That is, as in this embodiment, in order to share the image portion and the subtitle (character) portion in the movie with the master unit 1 and the slave unit 5 which are separate display devices, respectively, the image portion It is advantageous to broadcast or transmit in a form (digital data) that can separate the subtitle (character) portion from each other.
However, for example, the subtitles of the movie displayed on the master unit 1 are “automatically recognized” at high speed, “image data is converted to character data (text data)”, and the converted character data is converted into the slave unit 5. If it is transmitted to and displayed on the slave unit 5, subtitles can be displayed on the slave unit 5 in almost real time with the movie displayed on the master unit 1. The same is true for news commentary programs, etc., characters written on flips (signboards) used for news commentary are automatically recognized and converted to image characters at high speed and sent to the slave unit 5. May be displayed. If the contents of the flip are recorded as character data in a recording device built in the slave unit 5, the viewer can save the contents of the flip as character data in a database or the like.

(B) Next, while watching the relay program of the sport game, the viewer changes the operation mode of the slave unit 5 with the remote controller 9 as “ sub-screen (picture in the master screen of the master unit 1). An explanation will be given of the case where the mode is set to “largely display (by the in-picture function)” .
Now, when the viewer instructs to output a favorite player's profile while watching a sporting game, a sub-screen like “window” is displayed in the main screen of the main unit 1, and the child is displayed. The player's profile is displayed in the screen. At this time, the contents of the child screen (profile display) are simultaneously displayed on the display unit 5a of the child device 5 at or near the viewer. For the viewer, the display of the child screen is difficult to see from the distance of about 2 to 3 m (especially for people with myopia) only by the display of the parent device 1, but the child device 5 is Since it is in the viewer's hand, it is possible to see only the sub-screen clearly, as if it were a magazine or newspaper. The contents of the child screen displayed on the child device 5 are typically character information, but may be graphic information / video information.

  FIGS. 5A and 5B show another example of the operation of (B). 5A and 5B, reference numeral 14 denotes a screen of the master unit 1, and 15 denotes a screen of the slave unit 5. For example, when a celebrity talk program or the like is displayed on the screen of the main unit 1, if a viewer requests a profile of a person shown on the screen, a request is made to a part of the main unit 1 screen. A “window” -like “sub-screen” 14 a indicating the profile is displayed. However, there is a problem that the portion showing the profile is difficult to see from the display screen of the main unit 1 located at a position separated by about 2 m or more. Therefore, this profile can be displayed on the screen 15 of the handset 5 at the viewer's hand based on the radio signal from the base unit 1. As described above, in the present embodiment, the base unit 1 and the handset 5 cooperate with each other, so that the screen of the base unit 1 and the screen of the handset 5 are interlocked with each other, and display contents and roles are mutually related. It will be displayed while sharing.

  Further, in this embodiment, as shown in FIG. 5C, a “window” -like “child screen” 15a is displayed, for example, at the lower right position of the child machine 5, and the parent screen is displayed on the “child screen”. The display content of the “parent screen” of the machine 1 may be displayed as it is. That is, in this case, the contents of the “parent screen” and the “child screen” of the parent device 1 are the contents of the “child screen” and the “parent screen” of the child device 5, respectively (that is, the parent device 1 and the child screen). The contents of the parent screen and the child screen are reversed from each other on the child device 5). In this case, a viewer watching the handset 5 at or near the hand can grasp the contents of the profile and the contents of the master screen of the base unit 1 at the same time by simply looking at the display contents of the handset 5, which is convenient. is there.

(C) Next, while watching the relay program such as the sports game or the celebrity talk, the viewer changes the operation mode of the slave unit 5 with the remote controller 9 in the screen of the master unit 1 A case will be described in which a mode is set in which a person designated by the viewer among a plurality of videos is displayed on the handset 5 in a greatly enlarged manner.
Now, as shown in FIG. 6 (a), it is assumed that images obtained by simultaneously capturing three persons 18a, 18b, and 18c are broadcast and transmitted on the screen 16 of the base unit 1. In this case, for example, not only the above-mentioned “videos of the three persons 18a, 18b, and 18c simultaneously imaged” by data broadcasting using a gap between TV waves, information distribution by the Internet “push technology”, etc. At the same time, it is assumed that “three video data obtained by shooting up three persons each” is being broadcast and transmitted to the receiving terminal of the viewer (in this case, the master unit 1) .

First, while viewing the screen 16 of the main unit 1 shown in FIG. 6A, the viewer “displays an icon (pictograph) on the main unit 1 for selecting a screen obtained by imaging each person up”. Is transmitted to the base unit 1 by the remote controller 9. Then, as shown in FIG. 6B, pictograms 19a, 19b, and 19c are displayed on the images of the persons 18a, 18b, and 18c, respectively. Therefore, for example, when the viewer desires to display an up image of the person 18c on the child device 5, as shown in FIG. 6C , the viewer displays an icon 19c displayed on the person 18c. The cursor (arrow) 91 is used for selection and instruction . Then, as shown in FIG. 6 (d), the video data obtained by imaging the person 18c sent by the TV radio wave is sent to the slave unit 5 via the master unit 1, and the slave unit 5 On the screen 17, an up image of the person 18c is displayed.
In this case, as shown in FIG. 6D, the frame of the child screen 17a is displayed at the lower right corner of the screen 17 of the child device 5 (adopting the parent-child two-screen method), and this child screen 17a is displayed. In addition, the display content of the screen 16 of the parent device 1 may be displayed. In this way, the viewer can grasp not only the enlarged image of the selected specific person 18c but also the display content of the parent device 1 by simply looking at the screen 17 of the child device 1, which is convenient. There is .

(D) Next, while watching a relay program such as the above-mentioned celebrity talk or sports game, the viewer changes the operation mode of the slave unit 5 with the remote controller 9 as “a certain object (in this case, the celebrity's Video (multi-camera angle video) taken from multiple angles and locations (interviews and sports matches), taken from other angles and locations other than the video displayed on the main unit 1 A case where the mode of “display on the handset 5” is set will be described.
For example, when a sports game broadcast program (multi-camera, angle video program) is broadcast / transmitted from a TV station, for example, the TV station side “from the back of the back net, from the base 1 side, Images are taken from a plurality of (multi) camera angles such as “from the back screen side, from the base 3 side”, and the images of these multi camera angles are broadcasted and transmitted simultaneously to the viewer side. On the viewer side, it is possible to select and view videos freely from these videos. This is called "multi-camera angle broadcasting / transmission".

In the case of “multi-camera angle broadcasting / transmission” , usually, a picture taken with a camera angle selected by the broadcast station, for example, “from the back side” is displayed on the screen of the base unit 1. . Now, it is assumed that the viewer transmits a command “I want to display the video imaged at another camera / angle on the slave unit 5” to the master unit 1 using the remote controller 9 . Then, in one corner of the screen of the main unit 1, the camera angle other than the camera angle currently displayed on the main unit 1 “from the back of the back net” is “from the base 1 side, from the back screen side” Characters such as “from the 3rd base side” and an icon for selecting the same are displayed. Therefore, for example, when the viewer wants to display an image captured with a camera angle of “from the 1st base” on the handset 5, click the icon indicating “from the 1st base” to select To do. Then, the image taken with the camera angle “from the back side” is displayed on the base unit 1, and at the same time, the image is taken with the camera angle “from the base 1 side” on the handset 5. Will be displayed.
At this time, both the master unit 1 and the slave unit 5 are of a two-screen system, and the video “from the back net” is displayed on the master screen of the master unit 1, and “from the base 1 side” is displayed on the slave screen. At the same time, an image “from the base 1 side” may be displayed on the parent screen of the child device 5, and an image “from the back side” may be displayed on the child screen. That is, in this case, the display contents of the master unit 1 and the slave unit 5 are in a relationship in which the master screen and the slave screen are reversed from each other (similar to that shown in FIG. 6D).

(E) Next, while watching the relay program such as the celebrity talk, the viewer changes the operation mode of the slave unit 5 by using the remote controller 9 , for example, pointing / displaying on the screen of the master unit 1. A case will be described in which the mode of “displaying a part specified by the device in a large size on the slave unit” is set .
Now, it is assumed that a viewer is watching a celebrity talk program, and a video of a scene where a plurality of celebrities (actors etc.) are talking is displayed on the screen of the parent device 1. At that time, when only the face part of a celebrity who is a fan (favorite) is specified with a pointing device such as a mouse and clicked / selected, only the face part is enlarged, It is displayed on the display unit 5a of the slave unit 5 . Therefore, the viewer can enlarge and display only the face of a favorite celebrity (actor) on the handset 5 at hand and see it nearby.

  FIG. 7 is a diagram showing an example of the operation (E). In FIG. 7A, 16 indicates a screen of the parent device 1, and 17 indicates a display screen of the child device 5. Now, it is assumed that a viewer is displaying a program of a celebrity talk on the parent device 1. Therefore, three celebrities 18a, 18b, and 18c are shown on the screen of the base unit 1. Now, suppose that the viewer desires to enlarge only the face of the celebrity 18c who is a personal fan. In order to realize this, the viewer must first designate the “portion of the face of the celebrity 18c” (“the portion of the screen desired by the viewer”) with a pointing device such as a mouse. . FIG. 7B to FIG. 7D show this operation. First, as shown in FIG. 7B, when the viewer gives a predetermined instruction with the remote controller, the reference point 92 for designating the “part of the screen” is displayed on the screen 16 of the parent device 1. Is done. As shown in FIGS. 7C and 7D, the viewer designates the reference point 92 with the cursor (arrow) 93 and, for example, drags the cursor 93 to display the screen desired to be enlarged. Part of ". Then, the viewer instructs the parent device 1 to enlarge and display the designated “part of the screen” on the child device 5 by the remote controller 9. Then, as shown in FIG. 7 (e), this “part of the screen” (in this case, the face portion of the celebrity 18 c) is enlarged and displayed on the screen 17 of the handset 5.

In other words, the viewer wants to enlarge and display the designated “part of the screen” (the portion surrounded by the square shape shown by reference numeral 94 in FIG. 7D) on the handset 5 at hand. A command is issued to the base unit 1 through the remote controller 9. Then, video data corresponding to this “part of the screen” is transmitted from the parent device 1 to the child device 5 wirelessly in almost real time. This is because, since the screen of the main unit 1 is the “bitmap display method”, the image data of only “part of the screen” partitioned as shown in FIG. Wireless transmission to the machine 5 is possible. Based on this radio signal, the face portion (portion designated by the viewer using the pointing device) 94 of the celebrity 18c is enlarged and displayed on the handset 5. Even if the face of the celebrity 18c moves on the screen of the main unit 1, it is automatically tracked (tracked) by a computer program (for example, “agent (electronic secretary) technology”). The video of the face portion of the celebrity 18c is continuously transmitted from the parent device 1 to the child device 5, and the face portion of the celebrity 18c is continuously transmitted to the child device 5 (specified by the viewer). A part of the screen is enlarged).
In this case, as shown in FIG. 7 (e), the screen 17 of the handset 5 displays the face portion of the celebrity 18a in a large size, and a “child screen” 17a in the lower right corner. The video image currently displayed on the master unit 1 may be displayed in real time as it is on the child screen 17a. In this way, the viewer can conveniently grasp not only the magnified image of the face of the celebrity 18c but also the contents of the screen of the master unit 1 in real time simply by looking at the slave unit 5.

FIG. 9 is a diagram for explaining the operation of this function. 9A and 9B, the TV program selected by the viewer is displayed on the screen 53 of the parent device 1. On the other hand, the back program is displayed on the handset 5. The contents of the back program of the slave unit 5 are displayed on the slave unit 5 when a reception signal from the receiving antenna 2 (see FIG. 2) is transmitted to the slave unit 5 via the master unit 1 (relayed). (In the present invention, the signal from the reception antenna 2 may be transmitted directly to the antenna provided in the slave unit 5 without being relayed by the master unit 1).

  The back program displayed on the handset 5 may be any one back program selected by the viewer or a plurality of back programs selected by the viewer. In the example shown in FIG. 9, a total of nine back programs selected by the viewer are respectively displayed on a total of nine divided screens a to i with the screen display section divided. Then, for example, when the program displayed on the parent device 1 is in a CM (commercial), the viewer selects an arbitrary one of the programs displayed on the child device 5 and selects “This selected This command is immediately displayed on the display screen of the master unit 1 by wirelessly transmitting a command such as “Display the back program (for example, the reverse program displayed on the divided screen indicated by i in FIG. 9) on the master unit 1”. The displayed program (the program displayed on the divided screen i in FIG. 9) is displayed. As a configuration for the above-mentioned viewer to wirelessly transmit an instruction “display the selected back program (for example, the back program displayed on the divided screen indicated by i in FIG. 9) on the master unit 1”). Is, for example, provided with a “transparent touch panel” on the screen display unit 54 of the child device 5, and the viewer presses (touches) the divided screen i in FIG. The back program displayed on the divided screen i may be specified, and the channel of the specified back program may be transmitted to the main unit 1.

  In this way, when the back program selected by the viewer (the back program displayed on the split screen i in FIG. 9B) is displayed on the main unit 1, until then, The program displayed on the base unit 1 is replaced with the above-mentioned “back program displayed on the split screen i in FIG. 9B” and is newly displayed on the split screen i in the display screen 54 of the handset 5. It will be displayed. Then, for example, when the CM of the program newly displayed on the divided screen i is finished, the viewer reads “This program (changed from the parent device 1 and is currently displayed on the divided screen i of the child device 5. The above program is displayed again on the master unit 1 by wirelessly transmitting to the master unit 1 a command “display the program) on the master unit 1 again”. In place of this, on the divided screen i of the screen 54 of the child device 5, the program that has been displayed on the parent device 1 until then is displayed again as the back program.

  Next, FIG. 9C shows another similar operation, and a program list 54 a is displayed on the screen 54 of the handset 5. Although only a part of the program list is shown in FIG. 9C, the viewer can display all the programs by scrolling the program list up and down on the display screen 54. it can.
