Description

  The present invention relates to a broadcast receiving apparatus, and more particularly, to a receiver having a receiving unit capable of receiving a plurality of services belonging to a plurality of broadcast presentation units that need to be changed when selecting output based on event information and content data. The present invention relates to a broadcast receiving technique using an electronic program guide in Japan.

  In recent years, in television broadcasting, digitization has been promoted in terrestrial broadcasting as well as CS (communication satellite) broadcasting and BS (broadcast satellite) broadcasting. In multiple types of digital broadcasting such as CS digital broadcasting, BS digital broadcasting, terrestrial digital television broadcasting, etc., together with video information and audio information (content data) constituting the broadcasting event itself, for example, event name, event broadcasting date and time, SI (Service Information) including multiplexing of event information (information related to the broadcast event) such as event contents, event performers, etc. is also included in the digital broadcast signal and transmitted.

  The broadcast receiving apparatus displays an electronic program guide (hereinafter referred to as “EPG”) on the screen as a graphic user interface (GUI) that is easy for a viewer to select an event based on the SI. Can do. Using the EPG, a desired event can be selected on the screen, and the selected event can be displayed and the selected event can be reserved for recording.

  When various digital broadcast signals can be received, video and / or audio corresponding to the received digital broadcast signal is output, and various digital broadcast EPGs are switched and displayed based on the received event information. Is possible.

  The liquid crystal television receiver manufactured and sold by the applicant has the mechanism shown in FIG. As shown in FIG. 7, when viewing the terrestrial digital broadcast, the content 103 based on the terrestrial digital broadcast is displayed on the display screen 100. Here, for example, when an EPG display button of a remote control device is pressed, an EPG 105 of digital terrestrial broadcasting is displayed on the display screen 100 so as to be superimposed on the content 103.

Here, when the user presses a BS broadcast button with the remote control device, the EPG displayed on the display screen 100 is switched to the BS digital broadcast EPG, and the tuner selects the BS digital broadcast. Accordingly, the video and audio of terrestrial digital broadcasting are not output and BS digital video and audio can be output, but the video and audio are muted in the manufactured receiver. The EPG 140 is displayed on the display screen 100. The EPG 140 is roughly divided into a service display unit 141 and an event display unit 147. Furthermore, it is possible to move the cursor on the event display section of the EPG by operating the direction selection key of the remote control device, and processing related to the event associated with the area by pressing the enter key when stopped, for example, For an event currently being broadcast, a channel selection process for the service to which the event belongs, and for a future event, a reservation process for the event can be performed. The service display unit 141 is an area for displaying a service ID (channel number or the like) of a service belonging to a broadcast presentation unit displayed on the EPG, here, BS digital broadcast, and the event display unit 147 is a service display unit. The event content (broadcast title, etc.) 145 determined by the channel number and time is displayed on the event display section 147 defined by the channel number displayed in the column direction and the time axis in the horizontal direction. .

  In the figure, the event display unit 147 includes an area where no information is displayed. This area indicates that event information has not been acquired. For event information, information included in EIT, SDT, PMT, etc. is used. For example, when only EIT is used and information included in EIT is insufficient, information included in SDT or PMT is used as auxiliary information. The displayed types are different depending on the receiver specifications. After a certain period of time, unacquired event information can be obtained, and the EPG display of the event display unit 147 is displayed in an area where the event information is not displayed as indicated by reference numeral 147a. .

  On the other hand, FIG. 8 is a diagram showing an outline of the technique described in Patent Document 1 below. As shown in FIG. 8, content 203 is displayed on the display screen 200 while viewing digital terrestrial broadcasting. Here, when the EPG 205 is displayed by a remote control operation, the terrestrial digital EPG 205 is superimposed on the content 203 of the display screen 200. Here, when BS digital is selected by the remote control device, the EPG 207 displayed on the display screen 200 is switched to the BS digital EPG. However, video and audio are output as terrestrial digital. Since tuner tuning has not been switched, event information cannot be acquired even if time passes, and missing events are not filled.

  In order to display detailed information about a program (event) on BS digital or to perform reservation processing, for example, the cursor displayed on the EPG is selected by using the direction selection key of the remote controller, and the program (event) is selected. When the button is pressed, BS digital broadcasting is selected to obtain event information as indicated by reference numeral 211. Here, terrestrial digital video / audio is not output. On the other hand, for example, BS video / audio can be output, but this example is muted (product specification). Next, when the detailed information display of the program and the reservation process are completed and the display is returned to the BS digital EPG display, the event of the acquired event information is displayed. Furthermore, the event information can be acquired over time, and the event display The remaining events are displayed in the section.

  As described above, in the broadcast receiving apparatus disclosed in Patent Document 1, when a user performs an operation for the purpose of acquiring detailed information, necessary program information can be displayed.

JP 2001-211400 A (published on August 3, 2001; paragraphs [0092] to [0100], etc.)

  However, in an actual liquid crystal television, there is a problem that the video and audio of the program being viewed are interrupted even when it is desired to browse the EPG of another broadcast network (broadcast presentation unit) for a short period of time, which is inconvenient. .

  On the other hand, in the technique described in Patent Document 1, a network including an event is not selected unless an operation for viewing the detailed information of the displayed event or a recording reservation registration operation for this event is performed. Information could not be acquired, new displays were not added for events other than those displayed, and usability was poor. Further, if an event is not displayed, an operation for viewing detailed information and a recording reservation registration operation cannot be performed, and thus there is a problem that information regarding the event cannot be acquired.

  An object of the present invention is to provide a broadcast receiving technique capable of performing operations related to an EPG that is easier to use.

  According to an aspect of the present invention, a receiving unit that can receive a plurality of services, a plurality of services that are provided based on event information received by the receiving unit, and a list of events corresponding to the services An electronic program guide creating unit for creating an electronic program guide for each broadcast presentation unit; an electronic program guide created by the electronic program guide creating unit; and a display unit for displaying received content data; The electronic program guide creation unit is different from the first broadcast presentation unit to which the service being received belongs when the output corresponding to the received content data is performed from the display unit. When the first instruction to display the electronic program guide for the second broadcast presentation unit is received from the user, the electronic program guide for the second broadcast presentation unit is created and the display unit Provided is a broadcast receiving apparatus characterized in that, when there is unacquired event information related to the second broadcast presentation unit, an information acquisition start display for prompting information acquisition start is displayed on the display unit. .

  According to the broadcast receiving apparatus, when there is unacquired event information related to the second broadcast presentation unit, there is information that can be further acquired by the user by performing an information acquisition start display that prompts the start of information acquisition. I can let you know. At this time, since the information can be known without changing the channel selection, the process of returning to the first broadcast presentation unit can be simplified.

  The information acquisition start display is preferably displayed in an event information display area for displaying the event information. The information acquisition start display is preferably displayed in an empty area in which event information is not acquired in the event information display area for displaying the event information.

By displaying in the empty area, it can be emphasized toward the user that it is empty, and the difficulty of seeing by hiding event information is eliminated.
In response to a second instruction to move the cursor to the information acquisition start display, the receiving unit is controlled to receive a service belonging to the second broadcast presentation unit, and event information relating to the second broadcast presentation unit is obtained. It is preferable that an electronic program guide for the second broadcast presentation unit is created and output to the display unit.

  When receiving the first instruction from the user, the electronic program guide creation unit displays a cursor on the service list, and the second instruction moves the cursor from the service list to the event list. It is preferable to be based on the movement of. Since the channel selection is not changed until the second instruction, it is easy to return to the first broadcast presentation unit.

A digital broadcast receiving function television (hereinafter referred to as “digital broadcast television”) that displays an EPG of a digital broadcast based on the program arrangement information will be described as an example.

  Digital broadcasting currently includes BS digital broadcasting that uses BS (Broadcasting Satellite) to broadcast digital signals, and CS digital broadcasting that uses CS (Communication Satellite) to broadcast digital signals. There are three types of broadcasting: terrestrial digital broadcasting that transmits digitized broadcast waves from a terrestrial radio tower. As shown in FIG. 1, the digital broadcast television A according to the first embodiment of the present invention can receive any of the above three types of broadcasts. In digital broadcasting, there are currently three types of services: television broadcasting, radio broadcasting, and data broadcasting. The contents provided by these three services are video information and audio information for television broadcasting, audio information for radio broadcasting, and text information for data broadcasting. The digital broadcast television A is compatible with any of these three types of services, and can output content provided by each service as video and / or audio. In addition, since the difference in service is not related to the display layout of the display screen, in the following description, a case where a digital broadcast wave is a television broadcast will be described.

  Here, a data transmission system in BS digital broadcasting, CS digital broadcasting, and terrestrial digital television broadcasting currently used in Japan will be described.

  In BS digital broadcasting, CS digital broadcasting, and terrestrial digital television broadcasting currently used in Japan, multiple transport streams (hereinafter abbreviated as “TS”) are multiplexed on one transponder (frequency channel). Is being transmitted. The TS has a data structure that conforms to the standards of the Radio Industries Association (ARIB). The element sequence (ES) as content data (ES: Elemantary Stream) is the header for program sequence information as event information. As a TS packet added.

  The data structure of the program sequence information conforms to ARIB STD-B10 “Program sequence information standard used for digital broadcasting” which is the ARIB standard. Program sequence information includes PSI (Program Specific Information), which is transmission control information defined in the Moving Pictures Expert Group (MPEG) -2 system standard, and SI (Service Information) for constructing EPG and the like. Information). The PSI includes information on the frequency at which the TS is actually broadcast. SI is composed of four tables: BIT (Broadcaster Information Table), SDT (Service Description Table), EIT (Event Information Table), and TOT (Time Offset Table). Has been. The BIT describes information about a broadcasting station in the network. SDT is divided into a TS information part and a service information part. The TS information part includes a network ID for identifying the network and a TS ID (IDentifier) for identifying the TS. A network ID “4” is assigned to the BS network. Different network IDs are assigned to the CS1 network and the CS2 network, respectively. In digital terrestrial television broadcasting, different values of network IDs are assigned to each broadcasting station in the same region. The service information part includes a service ID (so-called channel number) that is an identifier for identifying each service (channel) in the network. The EIT describes program information for each event, and is divided into a service information part and an event information part. The service information part includes a service ID (so-called channel number) that is an identifier for identifying each service (channel) in the network. The event information section includes an event ID, event start time, event duration, event name (program title), event genre, and the like. TOT describes the current time.

  For details of the data structure of the program sequence information, the book “ARIB STD-B10“ Program Sequence Information Standard for Digital Broadcasting ”Version 4.0” distributed by ARIB (developed on December 14, 2004) It is described in.

  As shown in FIG. 1, the digital broadcast television A according to this embodiment includes a tuner 16, a speaker 6 as an output unit, and a display panel 7. The digital broadcast television A receives an instruction signal (signal light) based on an operation of an external remote controller 8 (shown in FIG. 2 and will be described in detail later), and performs an operation according to the received instruction signal.

  As shown in FIG. 1, the tuner 16 includes a digital demodulator (receiver) 2, a demultiplexer 9, an AV decoder 4, an audio controller 11, a display controller 13, a program sequence information storage unit 5, a remote control light receiver 14, And a control unit 3.

  The digital demodulator 2 is connected to an external antenna 1 that receives a digital broadcast wave (a high-frequency broadcast wave carrying a digital broadcast signal) of a BS digital broadcast, a CS digital broadcast, or a terrestrial digital television broadcast from a digital broadcast station. It is connected. In FIG. 1, the antenna 1 is described as one, but in reality, the antenna 1 may be three antennas for BS digital broadcasting, CS digital broadcasting, or terrestrial digital television broadcasting. A terrestrial digital television broadcast signal (broadcast wave) is transmitted from a terrestrial digital television broadcast station and received by a terrestrial digital television broadcast antenna.

  The digital demodulator 2 tunes to the channel of the desired service to extract the digital broadcast signal of the desired service from the digital broadcast signal received by the antenna 1 and to convert the digital broadcast signal into the baseband bit stream signal. Demodulate. The operation of extracting the digital broadcast signal of the desired service by tuning to the digital broadcast wave of the channel of the desired service is called channel selection. The digital demodulation unit 2 selects a service to be selected (tuned) in accordance with an instruction from the channel selection control unit 15 described later.

  As described above, the digital broadcast signal includes content data such as video data and audio data, and program arrangement information. Therefore, the bit stream signal demodulated by the digital demodulator 2 also includes content. Data and program arrangement information are included. The bit stream signal demodulated by the digital demodulation unit 2 is obtained by multiplexing a bit stream signal of event content data, a bit stream signal of program arrangement information, and the like.

  The demultiplexer 9 extracts a bit stream signal of program arrangement information from the multiplexed bit stream signal demodulated by the digital demodulator 2. That is, the demultiplexer 9 converts the multiplexed bit stream signal into a bit stream signal of video information (moving image information, still image information, character information, etc.), a bit stream signal of audio information, a bit stream signal of program arrangement information, etc. To separate. The demultiplexer 9 stores the program arrangement information in the program arrangement information storage unit 5. Further, the demultiplexer 9 sends a bit stream signal of video information and audio information to the AV decoder 4. Note that the program arrangement information included in the bit stream signal generally relates to EPG for about one week (for example, eight days) in the case of BS digital television broadcasting. The program arrangement information includes information on the event such as the name of the event, the broadcast date and time of the event, the content of the event, and the performer of the event.

  The AV decoder 4 performs a process of decoding the bit stream signal of the video information (compressed video information) sent from the demultiplexer 9 into a video signal in a format that can be processed by the display panel 7, and obtained by the process. A video signal is sent to an image composition unit 12 (to be described later) via a display control unit 13 (to be described later), and a bit stream signal of audio information (compressed audio information) sent from the demultiplexer 9 can be processed by the speaker 6. The audio signal is decoded into a format and sent to the speaker 6 via the audio control unit 11. The speaker 6 outputs sound according to the sound signal sent from the AV decoder 4. For example, MPEG (Motion Picture Experts Group) -2 Video is used as the compression format of the compressed video information included in the broadcast signal. For example, MPEG is used as the compression format of the compressed audio information included in the broadcast signal. -2 Use Audio AAC. These compression formats are not limited to these formats. For example, MPEG-4 Visual and H.264, which are international standard systems for moving picture coding technology. H.264 (MPEG-4 AVC) or the like may be used as a compression format of video information.

  The audio control unit 11 controls (stops etc.) the output of the audio signal to the speaker 6 based on an instruction from the EPG creation unit 10 described later.

  The display control unit 13 controls (stops etc.) the output of the video signal to the image composition unit 12 based on an instruction from the EPG creation unit 10 described later, and as a result, corresponds to the received broadcast signal. The display of the event video on the display panel 7 is stopped. The program sequence information storage unit 5 stores the bit stream signal of the program sequence information extracted by the demultiplexer 9.

  The remote control light receiving unit 14 receives a signal according to an instruction input by the user to the external remote control 8 from the external remote control 8 using infrared rays, and determines an instruction input by the user to the remote control 8 based on the received signal. An instruction signal corresponding to the instruction is sent to the control unit 3.

  The control unit 3 receives a user instruction to display an EPG as an instruction signal, and comprehensively controls operations of various components in the digital broadcast television A based on the instruction signal. The control unit 3 includes an EPG creation unit 10, an image composition unit 12, and a channel selection control unit 15.

  The EPG creation unit 10 divides a plurality of available services into a plurality of broadcast presentation units, and based on the program arrangement information stored in the program arrangement information storage unit 5 (more specifically, the EIT included in the SI of the program arrangement information) Based on the above, a plurality of EPG image signals for each broadcast presentation unit are created while switching according to a user instruction. The EPG indicates a list of a plurality of services belonging to a corresponding broadcast presentation unit and a list of the plurality of services. Here, there are three broadcast presentation units: BS digital broadcast, CS digital broadcast, and terrestrial digital television broadcast, which have different operational rules (standards) related to the event information distribution method. Therefore, in the present embodiment, the EPG creation unit 10 creates one by switching between an EPG for terrestrial digital television broadcasting, an EPG for BS digital broadcasting, and an EPG for CS digital broadcasting. The EPG is a matrix-shaped EPG in which event information is arranged in the service ID order (channel number order) in the vertical direction, and the event information is arranged in time order in the horizontal direction as a time axis. The EPG creation unit 10 creates an EPG image signal so that the display panel 7 displays at least a part corresponding to a part of the services of all EPGs that can be used in one broadcast presentation unit. The EPG creation unit 10 sends the created image signal of the EPG screen to the image composition unit 12.

  When receiving an instruction (second instruction) for moving the cursor from the service display unit of the EPG screen to the event display unit via the remote control light receiving unit 14 from the remote control 8, the EPG creation unit 10 broadcasts the event being viewed. An instruction to acquire program arrangement information of another broadcast presentation unit different from the broadcast presentation unit to which the service belongs belongs to the channel selection control unit 15 and the program arrangement information acquired and stored in the program arrangement information storage unit 5 is transmitted. By reading, program arrangement information of another broadcast presentation unit different from the broadcast presentation unit to which the service broadcasting the event being viewed belongs is acquired.

  When the EPG creation unit 10 receives an instruction (second instruction) for moving the cursor from the service display unit on the EPG screen to the event display unit via the remote control light receiving unit 14 from the remote control 8, the EPG creation unit 10 and the voice control unit 11 and An instruction to stop the output of the audio signal to the speaker 6 and the output of the video signal to the image synthesis unit 12 is sent to the display control unit 13, respectively, and as a result, the display of the event video on the display panel 7; And the output of the sound of the broadcast event in the speaker 6 is stopped.

  When the EPG creation unit 10 receives an instruction to move the cursor from the remote control 8 via the remote control light receiving unit 14 (instructions by the cursor keys 26 to 29), the EPG creation unit 10 moves the cursor based on the instruction to move the EPG screen. The process to display on top is performed. The EPG creation unit 10 also performs highlight display processing for the service display unit and the date / time display unit.

  The image synthesis unit 12 synthesizes the image signal of the EPG screen sent from the EPG creation unit 10 with the video signal of the event sent from the AV decoder 4, and outputs the obtained video signal to the display panel 7. As a result, the image composition unit 12 causes the display panel 7 to display the EPG screen image created by the EPG creation unit 10 on the display panel 7 so as to be superimposed on the video corresponding to the video signal from the AV decoder 4 (video of the broadcast event). By displaying in this way, the user can check the EPG while viewing the broadcast event. In the normal viewing state, since the image signal of the EPG screen is not sent from the EPG creation unit 10, the image composition unit 12 outputs the video signal sent from the AV decoder 4 to the display panel 7 as it is.

  The channel selection control unit 15 receives an instruction to select a service or a broadcast presentation unit switching instruction to be described later from the remote controller 8 via the remote control light receiving unit 14, and switches the channel to be selected according to the instruction. The digital demodulator 2 is controlled. Further, the channel selection control unit 15 can also receive an instruction from the EPG creation unit 10, and other broadcast presentations different from the broadcast presentation unit to which the service broadcasting the event being viewed belongs from the EPG creation unit 10. When receiving an instruction to acquire the unit program arrangement information, the digital demodulator 2 is controlled so as to switch the channel to be selected to at least one channel transmitting the program arrangement information of another broadcast presentation unit.

  The display panel 7 outputs a video signal including an event video and / or an EPG screen sent from the image synthesis unit 12 as a video. The display panel 7 is not particularly limited, and is a liquid crystal display panel, a plasma display panel, an organic EL display panel, or the like. Further, instead of the display panel 7, a CRT (cathode ray tube) display, a projection display device (projector), or the like may be used.

  As shown in FIG. 2, the remote controller 8 includes a key group for a user to input an instruction to the digital broadcasting television A (FIG. 1, hereinafter refer to FIG. 1), and according to the operation of the key group. Signals representing various instructions are sent to the remote control light receiving unit 14. The key group includes a program guide key 20 for displaying an EPG screen on the display panel 7 of the digital broadcast television A, three broadcast switching keys 21, and an event at the cursor position on the EPG screen (currently selected event). A determination key 25 for selecting or reserving a channel, an up cursor key 26 for moving the cursor on the EPG screen upward, a left cursor key 27 for moving the cursor on the EPG screen to the left, on the EPG screen A right cursor key 28 for moving the cursor to the right and a down cursor key 29 for moving the cursor on the EPG screen downward are provided. For example, when the program guide key 20 is pressed while an event video is being displayed, a signal indicating an instruction to start an EPG screen of a broadcast presentation unit to which a service broadcasting the event belongs is transmitted.

  The broadcast switching key 21 is a key for instructing switching of a broadcasting network, and is composed of three keys: a terrestrial digital television broadcasting key 22, a BS digital broadcasting key 23, and a CS digital broadcasting key 24.

  The broadcast switching key 21 inputs an instruction to switch the EPG created by the EPG creation unit 10 from one broadcast presentation unit EPG to another broadcast presentation unit EPG when the EPG is superimposed on the video of the broadcast event. Acts as a key.

  When the broadcast switching key 21 displays a broadcast event video without displaying an EPG, the channel selected by the digital demodulator 2 is changed from one broadcast presentation unit channel to another broadcast presentation unit channel. Functions as a key to input an instruction to switch to. There is an input from the broadcast switching key 21 corresponding to a broadcast presentation unit different from the broadcast presentation unit of the broadcast event currently being displayed in a state where the broadcast event video is displayed on the display panel 7 without displaying the EPG. In this case, the digital demodulator 2 acquires content data of an event being broadcast in synchronization with one service of a broadcast presentation unit (for example, CS digital broadcast) corresponding to the input broadcast switch key 21, and The event video is displayed on the display panel 7. For example, when the CS digital broadcast key 24 is selected, the digital demodulator 2 acquires content data of an event being broadcast in synchronization with one service of CS digital broadcast, and displays a video of the event being broadcast on the display panel. 7 is displayed.

  In the following, first, an outline of the technique related to the above Japanese Patent Application No. 2005-049949 will be described with reference to FIG. As shown in FIG. 3, it is assumed that the content is currently being viewed by digital terrestrial broadcasting on the display screen 300 of the digital broadcasting television. Please refer to FIG. 1 and FIG. 2 as appropriate. Here, when the button 20 for displaying the EPG is pressed by the remote control device, the digital terrestrial EPG 305 is superimposed on the content 303 and displayed on the display screen 300.

  Next, when the user presses the BS button 23 of the remote control device, the display screen is switched to the BS digital EPG. However, video and audio are still terrestrial digital. Even if the cursor is on the service display unit 306, even if time elapses, the event information is not further acquired, and the empty area 307 in the event information display unit 315 where information is missing is not filled with information. .

  When the cursor is moved from the service display unit 306 to the event display unit 315, the BS digital broadcast corresponding to the selected EPG is selected, and the video and audio of the terrestrial digital broadcast are not output. Is muted. When time elapses, event information can be acquired, and the empty area 307 of the event display section is filled with event information.

  Next, the digital broadcast television according to the embodiment of the present invention will be described. FIG. 4 is a diagram showing an outline of EPG related technology in the digital broadcast television according to the present embodiment. The description will be made with reference to FIGS. As shown in FIG. 4, terrestrial digital broadcasting is being viewed, and digital terrestrial broadcasting content 53 is displayed on the display screen 50. The cursor indicates the service display unit 61. In this state, when the user presses the EPG button 20 of the remote control device, it switches to BS digital EPG. Video and audio remain terrestrial digital. In this state, since the event information cannot be acquired even after a lapse of time, the acquired event information is already filled, but the event information in the empty area 58 of the event display unit 57 is not filled. .

  Here, when the remote control BS button is pressed, in the present embodiment, a display such as “start information acquisition with the cursor right key” is performed on the event display section 57 of the display screen 50. When the user looks at this display and operates the cursor right key with this display as a target, the cursor moves to the right and when the event display unit 57 is reached, the tuner switches to the BS and starts actual information acquisition. Can be made. That is, the display functions as a display for deepening the user's understanding and prompting the operation.

  When an operation for moving the cursor to the right side of the display screen 50 is actually performed by the movement button 28 of the remote controller, the cursor moves from the service display unit 61 toward the event display unit 57. When the movement of the cursor is detected, a process for switching to the broadcast corresponding to the service displayed on the EPG, in this case, the BS broadcast, is performed. At this time, the terrestrial digital video / audio is not output and the BS digital broadcast video / audio can be output, but may be muted here. In this state, since event information related to EPG of BS digital broadcasting can be newly acquired, the empty area 71 is filled with information as time passes. Eventually, all the event information 75 that can be acquired can be displayed on the event display section 45 of the EPG as shown in FIG.

  As described above, according to the broadcast receiving apparatus according to the first embodiment of the present invention, EPG of other broadcasts can be displayed while viewing a certain program, so that EPG related usability is improved. To do. In addition, a display that prompts the cursor to move from the service display unit to the event display unit, and further moves the cursor toward a display that means that the event information can be acquired. Since information is newly added and displayed, there is an advantage that convenience is increased.

  Next, a broadcast receiving apparatus according to a second embodiment of the present invention will be described with reference to the drawings. The difference between the broadcast receiving apparatus according to the present embodiment and the broadcast receiving apparatus according to the first embodiment is that, as shown in FIG. 4, when the remote control BS button is pressed, the event display section 57 of the display screen 50 is displayed. For example, when a display such as “start information acquisition with the cursor right key” is performed, a display such as “start information acquisition with the cursor right key” is displayed in the empty area 58 of the event display unit 57. It is characterized by making it.

  By displaying in the empty area 58 in this manner, there is an advantage that the current EPG display is not hidden by the above display, and the EPG display becomes easier to see.

  Next, the flow of processing in the first and second embodiments will be described with reference to the flowchart shown in FIG. As shown in FIG. 6, when the process is started (START), it is monitored in step S1 whether or not the switch key to any broadcast presentation unit is pressed, and if the key is pressed ( YES), the process proceeds to step S2, and it is determined whether or not the broadcast presentation unit pressed in step S1 is different from the currently displayed broadcast presentation unit. If they are different (YES), the process proceeds to step S3. If NO in steps S1 and S2, the process returns to step S1.

  When the process proceeds to step S3, the display is switched to the broadcast presentation unit EPG pressed in step S1. In step S4, a movable display is performed in the EPG. In the case of the first embodiment, the movable display is moved to the event display unit, and in the second embodiment, the movable display is moved toward the changeable display.

  Next, in step S5, it is determined whether or not an operation for moving the cursor toward the movable display is performed by the movement button of the remote controller. If it is determined that the cursor is moving toward the movable display (YES), the process proceeds to step S6. If the cursor is not moved (NO), the process proceeds to step S10. In step S6, the broadcast presentation unit pressed in step S1 is selected, and the original video / audio is stopped. Proceeding to step S7, the broadcast presentation unit event information pressed at step S1 is displayed on the event display unit.
