  Moreover, the television apparatus 1 may have the HDD 151 outside. In that case, the television apparatus 1 can be connected to the HDD 151 via, for example, a USB interface 125 and a USB terminal 124 compliant with the USB (Universal Serial Bus) standard. Further, the USB interface 125 and the USB terminal 124 can be connected to an external storage device (such as an HDD / card type storage medium (memory card)) prepared independently of the HDD 151.

  Note that the television device 1 may be configured not to include a tuner (multi-channel tuner). In that case, the television apparatus 1 is connected to a network such as an IP (Internet Protocol) communication network by the communication interface 123 and the LAN terminal 122, and can receive a program distributed by a program distributor (distributor). In this case, it is also possible for the television apparatus 1 to selectively acquire a streaming video (stream) by accessing a program provider (content server) on the network.

  A broadcast signal received by the antenna 101 is input to the input terminal 102. External input signals are input to the input terminals 104 to 107. As a source of the external input signal, for example, STB (Set Top Box (sometimes called an external tuner)), video recording device (sometimes called a recorder), video reproduction device (sometimes called a player) or Video camera device, etc. are optional. In particular, the video camera device is not controlled by the form of the camera device, and may be a portable terminal device capable of taking an image, such as a tablet PC (Personal Computer) device. Further, the signal processing unit 108 can perform decoding processing, image quality enhancement / sound quality enhancement processing on digital (or analog) video signals and audio signals supplied from the input terminals 104 to 107. If an analog signal is input, it is input to the signal processing unit 108 after A / D conversion by an A / D conversion circuit (not shown).

  The individual elements (sometimes referred to as modules or units) are each configured as a hardware circuit, and are connected to each other via an electric signal line such as a dedicated line or a general-purpose communication bus. ing. However, some of the individual elements described above may be realized by software that operates in the control of the controller 110.

  In the television apparatus 1 shown in FIG. 1, the input terminal 102 receives a broadcast signal (or external input signal) received by the antenna 101. The broadcast signal input to the input terminal 102 is selected by the multi-channel tuner 103 for each channel selected by the viewer (or reserved for automatic recording). The input unit 103 includes N (N is a positive integer) number of tuners 103a to 103n, and can receive (tune to) a maximum of N channel programs.

  A TS (Transport Stream) including the broadcast signal (program) of the selected channel is subjected to the following processing in the video decoder, audio decoder, and control information processing unit included in the signal processing unit 108. The video decoder, the audio decoder, and the control information processing unit, from the TS (Transport Stream) including the program of the selected channel, the video signal (video), audio / audio signal (audio) of the program of the selected channel, and Separated into control information, the video signal (video) and audio / audio signal (audio) of the program are decoded. Note that the number of video decoders and audio decoders included in the signal processing unit 108 is preferably equal to or greater than the number N of tuners included in the multi-channel tuner 103. In the embodiment, at least one video decoder and audio decoder are configured by hardware decoders, and the remaining number of tuners is configured by software decoders. Each hardware decoder or software decoder takes out PES (Packetized Elementary Stream) including high-priority specific information (and / or at least an I-frame image) included in the control information in TS and a character superposition. At the same time, the video PES and audio PES are decoded. Thereby, the cost of the signal processing unit 108 can be suppressed as compared with the case where hardware decoders corresponding to the number of tuners are prepared in order to decode the programs of all the channels.

  The hardware decoder included in the signal processing unit 108 decodes the TS demodulated (demodulated) by the software decoder for multi-channel display in addition to the program that is decoded (if necessary, scrambled (encrypted / decrypted) and reproduced). Receives and decodes the video signal (video) and audio / audio signal (audio) of the program of the channel selected from the TS (descramble (encryption / decryption) if necessary, and display the video for sub-screen display of multi-channel display) When hardware decoders are prepared for two or more tuners, one or more hardware decoders are used instead of software decoders to detect specific information with high priority. It can also be used for (removal).

  The controller 110 includes a central processing unit (CPU) 10, a read only memory (ROM) 11, a random access memory (RAM) 12, a nonvolatile memory 13, and the like.

  The controller 110 receives an operation input (user instruction) from the operation unit 115 and a command (control signal) sent from the remote controller (remote controller) 116 based on a control program stored in a ROM (Read Only Memory) 11. Controls the operation of each unit corresponding to the operation input received. Note that the receiving unit 117 and the remote controller 116 may transmit and receive operation signals by wireless communication using radio waves or the like, or may use infrared rays.

  The controller 110 also inputs an operation input from the same color key of the remote controller 116 for each of the [blue] button, [red] button, [green] button, and [yellow] button that OSD displays in the display area (screen) of the display 141. Accept. The operation input from each color key can be received by the controller 110 as various control commands determined in advance for each screen mode (for example, menu screen or selection screen) being displayed. Execution of control to be performed is instructed. Furthermore, the controller 110 sets individual programs (channels) to be displayed at the display positions of, for example, six sub-video display positions in the screen display of the display 141 described later with reference to FIG.

  The controller 110 is also connected via a card interface 120 to a card holder 119 in which a memory card 118 can be mounted. That is, the controller 110 can exchange (read and write) information with the memory card 118 attached to the card holder 119.

  The controller 110 is further connected to the LAN terminal 122 via the communication interface 123. Accordingly, the controller 110 can exchange (send and receive) information between the LAN terminal 122 and a LAN-compatible device connected thereto. That is, the controller 110 functions as a DHCP (Dynamic Host Configuration Protocol) server. In this case, the controller 110 assigns an IP address for each control to the LAN compatible device connected to the LAN terminal 122, and performs predetermined control for each LAN compatible device.

  Further, the controller 110 is connected to the HDMI terminal 128 through the HDMI interface 129. That is, the controller 110 can exchange information (transmission and reception of video signals, audio (audio) signals, and control signals) between any HDMI compatible devices connected to the HDMI terminal 128.

The controller 110 is also connected to the USB terminal 124 via the USB interface 125. That is, the controller 110 can exchange information (transmission and reception of video signals, audio / audio signals, and control signals) with a USB compatible device (for example, the HDD 151 described above) connected to the USB terminal 124.
The controller 110 controls the brightness of the video (image) displayed on the display 142 and the backlight (illumination light) according to the brightness detection signal detected by the brightness sensor 121.

  The graphic processing unit 112 superimposes and outputs the OSD signal generated by the OSD (On Screen Display) processing unit 111 on the digital video signal supplied by the signal processing unit 108.

  The digital video signal output from the graphic processing unit 112 is input to the display 141 by the video processing unit 113 after the display processing for the actual screen display according to the reproduction characteristics of the display 141 in the subsequent stage. The graphic processing unit 112 has been playing back a video signal (video) decoded by the signal processing unit 108 or a program with very high priority information detected by the control information processing unit. Processing for changing the display size of the main video and multiplexing a plurality of sub-videos is performed so that the video is displayed on the same screen. As will be described later with reference to FIG. 2, the graphic processing unit 112 displays a plurality of, for example, six sub-videos displayed at predetermined positions with respect to the display position of the main video on the display 141 and the display position of the main video Set the display position of the position. Further, the graphic processing unit 112 sets a display position of auxiliary display for displaying auxiliary display independent of the display positions of the main video and the sub video displayed on the display 141. The graphic processing unit 112 can output the output of the OSD processing unit 111 by superimposing the output video signal on the output video signal so that a part of the output video signal of the signal processing unit 108 can be transmitted. The graphic processing unit 112 also selectively outputs the output video signal of the signal processing unit 108 and the output OSD signal of the OSD processing unit 111 as the output of the OSD processing unit 111, and both outputs constitute half of the screen. It is possible to output it in combination as described above. The graphic processing unit 112 can arbitrarily set the size and position of the screen display or the transmittance when the outputs of the OSD processing unit 111 are superimposed. In addition, the graphic processing unit 112 can arbitrarily set the number of sub-pictures displayed on the same screen display by the display 141. Based on the processing of the controller 110 corresponding to the instruction input from the viewer (user), for example, 3 A sub-picture display position of about ~ 7 is set. The display size of the sub video is set to a predetermined size together with the display size of the main video, but can be arbitrarily changed based on the processing of the controller 110 corresponding to the instruction input from the viewer.

  The sound processing unit 114 converts the input digital sound (audio) signal into an analog sound (sound) signal in a format that can be reproduced by the speaker 142, and makes the speaker 142. Note that the audio processing unit 114 outputs an audio (acoustic) signal attached to the main video when a sub-video is displayed on the display 141.

  FIG. 2 shows an example of a screen display displayed on the display in response to the video display signal output from the video processing unit.

  The screen display 151 shown in FIG. 2 includes a main video display area (may be referred to as a main screen or a main screen display) 152 and first to sixth sub video display areas (may be referred to as a sub screen or a sub screen display). ) 153 to 158 and an auxiliary display display area 159.

  The main video display area 152 displays, for example, a video of a program of an arbitrary channel selected by the viewer (may be displayed as CH or may be referred to as a broadcasting station or a distribution source). The main video display area 152 resumes the CH of the program received at the time when the power of the television apparatus 1 is turned off when the power of the television apparatus 1 is turned on, and is currently broadcast on that CH. Displays the video of the current program. In FIG. 2, the program displayed in the main video display area 152 is referred to as “program 123”.

  The first to sixth sub-picture display areas 153 to 158 display “program A”, “program B”, “program C”, “program D”, “program E”, and “program F”, respectively. . In the example shown in FIG. 2, each of the sub-picture display areas 153 to 158 includes “program A”, “program B”, “program C”, “program D”, “program E”, “program F”. ”, But the sub-picture display area corresponding to the channel where the program is not broadcast is preferably, for example, black screen display (video non-display). The arrangement (display order) of the sub-picture programs (CH) displayed in the respective sub-picture display areas 153 to 158 is, for example, the order of the CH numbers in ascending order (or descending order), for example, the number of times the viewer has watched. Arbitrary order, etc. are arbitrary. In addition, the sub-video display area that does not display video (black screen display) is selected in the order from the first sub-video display area 153 when selection of all programs (CH) to be displayed in the sub-video display area is completed. Alternatively, they may be aggregated (sorted) in the order closer to the sixth sub-picture display area 158.

  The sub-pictures displayed in the respective sub-picture display areas 153 to 158 may be stored programs (contents) reproduced by the recorder device or the player device, or programs (contents) that can be acquired through a network, for example.

  The first to sixth sub-picture display areas 153 to 158 are respectively program information display areas 153A, 154A, 155A, 156A, 157A, 158A, CH number display areas 153B, 154B, 155B, 156B, 157B, 158B and CH ( Broadcast station / distributor / supplier) including logo mark display areas 153C, 154C, 155C, 156C, 157C, 158C.

  Each of the program information display areas 153A to 158A is preferably located at the lower part of each display area, for example. Each program information display area 153A to 158A displays, for example, a program name (title) of the program (CH) being received (individual display areas are displayed as sub-pictures). Each of the program information display areas 153A to 158A displays a program description of the program displayed as a sub-picture, such as genre, story outline (summary), performer name, identification of initial broadcast and rebroadcast, etc. It may be a thing. When the program description exceeds the size of the individual display areas 12A to 17A (all explanations (information) cannot be displayed in the display area), the display target character string is scrolled to display all messages. Is preferred. For example, for a focused sub-picture, the size of the display area may be temporarily enlarged so that a message of, for example, about 3 lines can be displayed, so that the viewer can easily see the program description. preferable. This can increase the viewer's willingness to view the program (CH) that may be considered as a candidate for viewing (in which the viewer is focused). The program description of the focused sub-video may be temporarily displayed in a pop-up in the main video screen display.

  In addition, in the display area included in the sub-video, related information related to the CH (program), for example, information at the time of broadcasting in the past and information about the next broadcasting is displayed for the focused sub-video (CH). May be. Also in this case, the size of the display area may be temporarily enlarged, or pop-up display may be performed for a predetermined period (time) within the main video screen display. In addition, as the information at the time of broadcasting in the past, it is possible to refer to, for example, program information used for displaying a past program guide. In addition, information related to the next broadcast can refer to program information included in an EPG (Electric Program Guide) for recording reservation.

  Each of the CH number display areas 153B to 158B displays the CH number of the program being received (individual display areas are displayed as sub-pictures), for example, with a three-digit number.

  Each CH (broadcasting station / distribution source / supply source) logo mark display area 153C to 158C is the broadcasting station, distribution source, or supply of the program being received (individual display areas are displayed as sub-pictures). A logo mark and a CH icon that can recognize the source (easily) are displayed.

  The CH number display areas 153B to 158B and the logo mark display areas 153C to 158C are located at arbitrary positions in the individual sub-picture display areas 153 to 158. The CH number display areas 153B to 158B and the logo mark display areas 153C to 158C are displayed integrally (closely) in many cases, but may be displayed at different (independent) positions.

  The auxiliary display display area 159 displays, for example, program information displayed in the main video display area, for example, program name, broadcast time, number of times of continuous broadcast (sum), summary of previous broadcasts, and the like. indicate. The information displayed by the auxiliary display is, for example, text (character information) attached to the main video (displayed integrally in the screen display of the main video), CH display, and / or logo mark of the broadcasting station. May be. In addition, the information displayed by the auxiliary display mainly includes text (character information), a CH display, and a logo symbol of the broadcasting station, and broadcasts of other channels not displayed by either the main video or the sub video. Information may be displayed every predetermined time. The information displayed by the auxiliary display is not necessarily highly directly related to the broadcast being received, such as the time and day of the week, but is preferably information useful for the viewer. . The third auxiliary display may be a display including a weather forecast of the area where the television device 1 is installed. Further, the information displayed by the auxiliary display is information regarding broadcasting of other CHs that are not displayed by either the main video or the sub-video, and is currently viewed by other viewers that can be acquired from the SNS server, for example. It may be a display relating to the viewing status (viewing rate, etc.) of the program being viewed. The information displayed by the auxiliary display may also be information (advertisement) of a program broadcast in the next time zone (broadcast time frame) on the CH (broadcasting station or distribution source) currently displayed in the main video, for example. Good. The information displayed by the auxiliary display may further be, for example, a display of an advertisement (advertisement) of a broadcast program broadcast by an arbitrary broadcasting station or distribution source. Note that the information displayed by the auxiliary display may be displayed by switching the above-described information at a predetermined timing. Moreover, it is preferable that the information displayed by the auxiliary display can be stopped by, for example, a (user) remote control operation. If the information displayed by the auxiliary display is detected to have received a program with very high priority information as described below, the display of the information displayed so far is interrupted and the priority is displayed. It is preferable to display very high information.

  Next, an example of a method for displaying a program (information with very high priority) by the controller 110 will be described.

The control information separated by the signal processing unit 108 includes, for example, SI (Service Information, Program Sequence Information) / PSI (Program Specific Information) describing TS distribution rules and contents, schedule or timing, and EPG information. The controller 110 extracts PAT (Program Association Table), CAT (Conditional Access Table), NIT (Network Information Table), and PMT (Program Map Table) from the PSI included in the control information, and each tuner 103a of the multi-channel tuner 103. The program of the channel received by ˜103n is reproduced. Note that SI is information provided by extending PSI (Program Specific Information), which is information describing to which program an ES (Elementary Stream) that is a video, audio, etc. included in the TS belongs. Information including SDT, EIT, etc. for displaying channel names and program information. In addition, PSI is schematically shown in FIG. 3, but when information with very high priority is broadcast in the first description loop 321 of the description of the structure 301 of the PMT, it is displayed ( To be described). That is, when information having a very high priority is broadcast, the description preceding the description 322 indicating the end of the first description loop in the preceding stage of the second description loop 323 including the description of ES is shown in FIG. 4 schematically shows information with very high priority, particularly an EWS (Emergency Warning Signal) 401 indicating “character super”. In addition, EWS is defined as “character supermarket” that is broadcast (transmitted) independently of the program in the standard specified by the Association of Radio Industries and Businesses, that is, ARIB (Association of Radio Industries and Businesses). Has been. Here, "Independent of the program ..." means that the service related to the content of the video among the services that display characters superimposed on the video of the television broadcast is classified as "subtitles" Other than that is "Character Super". “Character Super” is defined as a subtitle service that is asynchronous with the main video / audio / data, breaking news, organization change, hourly report, earthquake early warning, etc. In the description in the first description loop 321 of the PMT shown in FIG. 3, EWS is described as “descriptor_tag (descriptor tag)“ 0xFC ””. Further, as an operational rule, it is stipulated that a descriptor tag indicating EWS is described in the PMT throughout the broadcast of EWS. Therefore, in the controller 110, when the control information processing unit of the signal processing unit 108 detects that a descriptor tag having “descriptor_tag is“ 0xFC ”” exists in the first description loop 321 of the PMT. Thus, it is possible to specify that “character super”, in particular, “emergency information” is transmitted (broadcast).

  “Character Super” is normally transmitted (broadcast) as PES, but any number of packets (belonging to one PES) included in PES is “empty”, that is, there is information in the packet. There may not be. Therefore, when the control information processing unit of the signal processing unit 108 detects that a descriptor tag having a description “descriptor_tag is“ 0xFC ”” exists in the first description loop 321 of the PMT, It is preferable to confirm that information exists in the packet belonging to the defined PES.

  When the control information processing unit of the signal processing unit 108 detects reception of a program (broadcast) attached with very high priority information (“emergency information” / “character supermarket”) by the detection processing described above, the graphic processing unit 112, under the control of the controller 110, switches the display 141 to the multi-channel display shown in FIG. 2, and displays a program attached with “emergency information” / “text super”) in a predetermined area of the sub-picture display area. (When the display 141 displays a single program and a program other than the program being displayed is displayed). That is, even if it is detected that a program (broadcast) with “emergency information” / “text super”) is detected in a program that is not directly viewed by the viewer, it is the same as that being viewed , Information with very high priority can be displayed on the display 141. In addition, when the display 141 displays a plurality of programs in a multi-channel display, an “emergency” is displayed on a channel different from the channel displayed in the main video area, that is, in any program displayed in the sub-video. When a broadcast of a program attached with “information” / “text super” is detected, it is preferable to display the program of the channel in the main video display area. In the case where the display 141 displays a plurality of programs in a multi-channel display, and a broadcast of a program attached with “emergency information” / “text super” is detected in the channel displayed in the main video area. Alternatively, the multi-channel display may be stopped to provide a single screen display. In addition, the detection of information having a very high priority as described above can be realized even in cases other than “emergency information” or “text super” broadcasting. For example, even when “Emergency News (Emergency News Descriptor)”, which is standardized by the Association for Promotion of Advanced Broadcasting Services (A-PAB), is detected, the screen display is similarly controlled. It is preferable to do. Note that the television apparatus 1 may be provided with sensors capable of detecting, for example, shaking and temperature, means for receiving an earthquake early warning attached to a mobile phone, and the like, and detection using them may be used together. In addition, the video displayed in the sub-video display area or the main video display area is arbitrary, such as a still image (including an image obtained by capturing an arbitrary display) or a display including only character information (including a graphic).

  FIG. 5 shows, in software, an example of detection processing of a broadcast (program) to which “information with very high priority (“ emergency information ”/“ text super ”)” is attached.

  When receiving a broadcast (program) with “very high priority information (“ emergency information ”/“ text super ”)” included in the broadcast of any channel while receiving a program of any channel ([ 51] -YES), the display processing unit (graphic processing unit / controller) is notified that the program attached with "emergency information" (information with very high priority) is received ([53]).

  Note that a broadcast (program) with “high priority information (“ emergency information ”)” is not received ([51] -NO), and a broadcast with “text super” ( When information is present in the packet belonging to the PES included in “Character Super” when the (program) is received ([52] -YES), similarly (the information has a very high priority) Notify that the program attached with “Emergency information” is received ([53]).

  FIG. 6 shows, in software, an example of display control of the display processing unit when a broadcast (program) accompanied by “emergency information” / “text super” is detected.

  The controller 110 confirms that the display mode (display setting) set in the graphic processing unit 112 is a setting for performing multi-channel display ([61]).

  If the setting is to perform multi-channel display ([61] -YES), the controller 110 causes the control information processing unit of the detection unit, that is, the signal processing unit 108 to broadcast (program) with “emergency information” / “superimpose of characters”. ) Is received ([62] -YES), the display mode of the display 141 is switched to multi-channel display, and a broadcast (program) with “emergency information” / “text super” attached is displayed. ([63]). If multi-channel display is not set ([61] -NO), the detection function of “Emergency Information” / “Character Super” by the detection unit is not operated (the detection function is stopped), thereby reducing the power consumption. It is possible to reduce. The setting as to whether or not to perform multi-channel display is set in advance and can be set and stored according to preferences by using a setting menu technique using a well-known GUI.

  In this way, the hardware that decodes the main video indicates that a broadcast (program) with “high priority information (“ emergency information ”/“ text super ”)” is received in any channel broadcast. Independent of the hardware decoder, for example, by detecting by the control information processing unit of the signal processing unit 108, the user (viewer) is provided with an opportunity to visually obtain “emergency information” without increasing the device cost. it can.

  Also, by using “Character Super” to obtain “Emergency Information”, the emergency information is displayed at an earlier timing compared to the case where the emergency information is displayed by analyzing subtitles etc. in the program. it can.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention.
