In FIG. 7, a signal received by a BS antenna (not shown) is supplied to a terminal 50. The tuner 1 performs channel selection processing on the received signal input from the terminal 50, and then outputs the signal to the demodulator 2. The demodulation unit 2 demodulates the signal input from the tuner unit 1 and outputs a bit stream of the demodulated signal to the error correction unit 3. The error correction unit 3 detects and corrects an error of the bit stream input from the demodulation unit 2 and outputs the error to the transport decoding unit 10.

[0005] The transport decoding unit 10 performs demultiplex processing on the bit stream input from the error correction unit 3, outputs a video signal of a program designated and viewed by the user to the video decoding unit 8, and Is output to the audio decoding unit 11.

[0006] The video decoder 8 decodes the video signal input from the transport decoder 10 and outputs it to the display controller 9. The display controller 9 is controlled by a control signal from the system controller 13, performs video signal processing on the decoded video signal input from the video decoder 8, and outputs the processed video signal to a display device (not shown) via the terminal 52. The video signal processing performed by the display control unit 9 is a process of switching to a video signal for performing an electronic program guide or a warning display, or a process of multiplexing the electronic program guide or the warning display with a program being viewed.

The audio decoding section 11 decodes an audio signal input from the transport decoding section 10 and outputs it to a speaker (not shown) via a terminal 53.

[0008] The transport decoding unit 10
The signal for which recording is specified by the user is demultiplexed and output to the recording processing unit 7, and a data signal such as program information is output to the memory 12. Recording processing unit 7

(Ectric Program Guide, electronic program guide) can be automatically displayed, and user operations can be simplified.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of a broadcast receiving apparatus according to the present invention will be described with reference to FIG. The same components as those shown in FIG.

Referring to FIG. 1, in the broadcast receiving apparatus according to the present embodiment, a signal having received a BS digital broadcast is input via a terminal 50, and the processing is performed as described in the background art. The error correction unit 3 outputs the bit stream in which the error has been detected and corrected to the transport decoding unit 10.
The signal input to the terminal 50 may be a signal that has received a CS digital broadcast.

A signal received by a terrestrial digital broadcasting antenna (not shown) is input to the tuner 4 via a terminal 51. The tuner 4 performs channel selection processing on the received signal input from the terminal 51, and then outputs the signal to the demodulation unit 5. Demodulation unit 5
Demodulates the signal input from the tuner 4 and outputs a bit stream of the demodulated signal to the error correction unit 6.
The error correction unit 6 detects and corrects an error in the bit stream input from the demodulation unit 5 and supplies the error to the transport decoding unit 10.

The transport decoding unit 10 performs demultiplex processing on the bit stream input from the error correction unit 6, outputs a video signal of a program designated and viewed by the user to the video decoding unit 8, and outputs an audio signal. Is output to the audio decoding unit 11.

In the subsequent signal processing, the same operation as that of FIG. 7 described in the prior art is performed, except for the case where the reception state is deteriorated.

The tuner section 4, demodulation section 5, and error correction section 6 are also controlled by the system controller 13 similarly to the conventional system shown in FIG.

Next, the operation when the receiving condition of the satellite broadcasting system is deteriorated due to rainfall or the like will be described.

The error correction unit 3 corrects the error more than a predetermined number of times within a certain time when counting up the number of uncorrectable errors in the error correction unit 3 due to the poor reception condition of the satellite broadcasting system due to rainfall or the like. When an impossible error is detected, an error information signal indicating an unreceivable state is output to the system controller 13.

Alternatively, the transport decoding unit 1
At 0, the number of uncorrectable errors may be counted up. The counting operation of the transport decoding unit 10 will be described in more detail with reference to FIG.

[0027] When the reception state of the satellite broadcasting system deteriorates due to rainfall or the like and error correction is impossible, the error correction unit 3 sets the transport error indicator (Transport error indicator) in the header of the transport stream signal. transport # er
ror_indicator). When the error detection unit 22 in the transport decoding unit 10 detects that the transport error indicator is 1 (the flag is set) a predetermined number of times or more within a predetermined time, an error indicating an unreceivable state is detected. An information signal is output to the system controller 13. Here, the transport decoding unit 10 of FIG. 2 includes one error detection unit 22 and one demultiplex unit 23, and the two bit streams from the error correction unit 3 and the error correction unit 6 are 1 bit. Are supplied to the two error detectors 22. The error detector 22 and the demultiplexer 23 are provided in two pairs, and the two bit streams from the error correction unit 3 and the error correction unit 6 are respectively different from each other. Alternatively, a configuration may be adopted in which the power is supplied to the power supply 22.

(Display of EPG so as to be identifiable when reception condition deteriorates) First, an example in which an EPG is displayed as shown in FIG. 3 when a program being viewed becomes unreceivable will be described.

The memory 12 stores data for creating an EPG in advance. The data for creating this EPG is updated to the latest data at, for example, 30 minute intervals, and data is sent, for example, one week ahead.

When an error information signal is supplied from the error correction unit 3 or the transport decoding unit 10, the system controller 13 receives the error information signal from the data signals such as BS and terrestrial digital broadcast program information acquired from the memory 12. An EPG of a program in a good state is created, a video signal for displaying the screen shown in FIG. 3 is created, and output to a display device (not shown) via the display control unit 9. At this time, the EPG is displayed so that a program that can be viewed in a good reception state and a program that cannot be viewed in a bad reception state can be identified.

For example, when there are a program having a good reception state and a program having a bad reception state even in a BS digital broadcast, as shown in FIG. Alternatively, the EPG may be displayed so that the user can identify it. Thereby, the user can select a program to be viewed from more programs. Further, as shown in FIG. 3B, an EPG may not be displayed for a program whose reception condition has deteriorated. As a result, only receivable programs can be displayed on the EPG, so that the display screen can be used more effectively for selecting a program to be viewed. Also, as shown in FIG. 3 (c), when the reception condition of the BS digital broadcast is deteriorated, an EPG relating to the program of the terrestrial digital broadcast is created, and when the reception condition of the terrestrial digital broadcast is deteriorated. For example, an EPG for a BS digital broadcast program may be created. This is because when the reception state of a program that is a BS broadcast is deteriorated, the entire BS broadcast is deteriorated. In the case of analog broadcasting, the reception state is detected by detecting S / N.

(EPG display of the same genre when reception condition deteriorates) Also, as shown in FIG. 3D, the EPG to be created is limited to programs of the same genre as the program immediately before the reception becomes impossible. An EPG may be created and displayed. When limiting to programs of the same genre, the system controller 13 compares the genre information attached to each program with the same genre as the program immediately before the program becomes unreceivable, thereby determining whether or not to place the program on the EPG whose genre is limited. Is determined. This genre information uses information transmitted from a broadcasting station as service information.

(When the receiving condition deteriorates, multi-screen display) Next, when the program being viewed becomes unreceivable, a multi-screen is displayed for receivable programs as shown in FIG. An example will be described.

FIG. 4 shows the program numbers.
Actually, the video (moving image / still image / intermittent moving image) of the program is displayed on the background.

When an error information signal is supplied from the error correction unit 3 or the transport decoding unit 10 for the program being viewed from the system controller 13, the system controller 13 sequentially switches and decodes programs having good reception conditions to decode the program. Create and display multiple screens. FIG.
As shown in (b), a program may be selected from the multi-screen by moving the cursor (bold frame of the program) up, down, left and right.

At this time, if a multi-screen program for program introduction has been sent from the broadcast station in advance, the sent multi-screen program may be selected and displayed.

When the sound of the program selected by the user on the multi-screen is to be output from the speaker, the system controller 13 controls the demultiplex processing of the transport decoding unit 10 and selects the selected one. The audio signal of the program is supplied to the audio decoding unit 11. Thus, the audio signal of the program selected by the user is reproduced from the speaker (not shown).

(Multi-screen display of the same genre when reception condition deteriorates) Also, as shown in FIG. 4C, for example, a program of the same genre as the program immediately before the EPG to be further created becomes unreceivable is displayed. A limited number of multi-screens may be created and displayed on the display device. When limiting to programs of the same genre, the system controller 13 compares the genre information attached to each program with the same genre as the program immediately before the program becomes unreceivable, thereby determining whether or not to place the program on the EPG whose genre is limited. Is determined.

When the audio of the program selected by the user on the multi-screen is to be output from the speaker, the system controller 13 controls the demultiplex processing of the transport decoding unit 10 and selects the selected one. The audio signal of the program is supplied to the audio decoding unit 11. Thus, the audio signal of the program selected by the user is reproduced from the speaker (not shown).

(If the reception condition deteriorates, the same program is broadcast simultaneously if another is being broadcast) Next, if the program being viewed becomes unreceivable, the same program as the program being watched will be replaced. A method of shifting to and displaying a broadcast that has been simultaneously broadcast by another will be described. Note that this selection is shifted to a program whose reception state is good when the reception becomes impossible.

The term "same program" used in the present specification means, for example, a program in a broadcasting form in which the same broadcasting station broadcasts exactly the same in terrestrial broadcasting and satellite broadcasting. A broadcast-type program in which a station broadcasts the same baseball game shot by a different camera is also “the same program”.

When an error information signal is supplied from the error correction unit 3 or the transport decoding unit 10 for the program being viewed from the system controller 13, the system controller 13 acquires the program information read from the memory 12 and views the program up to now. Using the program title information or the like, a search is made to see if any other programs are being broadcast at the same time and have good reception conditions. As a result of this search, when the same program is simultaneously broadcasted and a good reception condition is found, the system controller 13 acquires the program information from the memory 12 and sends the program information to the transport decoding unit 10. While supplying the program information to the tuners 1 and 4 to change the program. As a result, it is possible to record a program that is being broadcast elsewhere simultaneously in the recording processing unit 7. For example, when the same program is being carried out by the BS and the terrestrial wave, and the reception condition of the BS deteriorates, the program is switched to the same program of the terrestrial wave having a good reception condition.

(When the receiving condition deteriorates, the program is selected by going back through the program selection history) Next, when the program being viewed becomes unreceivable, the program is shifted to the program selected before the program being viewed. A method of displaying the information will be described. Note that this selection is shifted to a program whose reception state is good when the reception becomes impossible.

When the system controller 13 is supplied with an error information signal from the error correction unit 3 or the transport decoding unit 10 for the program being viewed, the system controller 13 traces back the program selection history using a remote controller or the like, and first selects a program whose reception state is good. And switches to the detected program. The system controller manages these program selection histories.

(When the reception condition deteriorates, the program selection history is traced back to the program selection voice notification) In this way, the program selection history is traced back, and the program whose reception condition is good is detected first, and the detected program is displayed. At the time of switching, it may be notified that the program has shifted to a program with a good reception condition, or the program to which the program has shifted is sounded. When the transition to a program with a good reception state is completed, the system controller 13 uses the program title and the like included in the EPG from the memory 12 to determine which program has a bad reception state and to which program. The audio data to be guided is created, and the audio signal is output to the audio decoding unit 11. Thus, the user can be notified of the information of the program transition by voice. The generation of the voice data is performed by using a well-known voice synthesis technique, but is not an essential part of the patent and will not be described.

(When the reception condition deteriorates, if another same program is being broadcast, the program shifts and records.) Next, when the reception becomes impossible during recording, the same program is input with a good reception condition. In the following, a description will be given of an operation of shifting to the channel and continuing the recording when the program is being broadcast, and automatically setting the recording reservation by the receiving apparatus when the same program is scheduled to be broadcast.

The term “same program” used in the present specification means, for example, a program in a broadcasting form in which the same broadcasting station broadcasts exactly the same in terrestrial broadcasting and satellite broadcasting. A broadcast-type program in which a station broadcasts the same baseball game shot by a different camera is also “the same program”.

When an error information signal is supplied from the error correction section 3 or the transport decoding section 10 for the program being viewed from the system controller 13, the system controller 13 acquires the program information read from the memory 12 and records the program information so far. Using the program title information or the like, a search is made to see if any other programs are being broadcast at the same time and have good reception conditions. As a result of this search, when the same program is simultaneously broadcasted and a good reception condition is found, the system controller 13 acquires the program information from the memory 12 and sends the program information to the transport decoding unit 10. While supplying the program information to the tuners 1 and 4 to change the program. As a result, it is possible to record a program that is being broadcast elsewhere at the same time in the recording processing unit 7. For example, when the same program is being carried out by the BS and the terrestrial wave, and the reception condition of the BS deteriorates, the recording is performed by switching to the same program of the terrestrial wave having a good reception condition.

When a desired program is scheduled to be broadcasted, the system controller 13 acquires program information from the memory 12, supplies a recording reservation information signal to the recording processing section 7, and sets a recording reservation.

Then, the system controller 13 notifies the user that the recording reservation has been made by supplying the display control unit 9 with information on the changed program.

Thus, the user can continuously view / record the same program if the same broadcast is being performed elsewhere.

(Receiving Condition Once Degraded, but Regained Good) Next, the operation when the receiving condition is deteriorated, for example, when the weather recovers and the receiving condition becomes good again explain.

When the program can be returned to the user at the time of viewing or recording, it is notified by video or audio that the program can be returned.
An operation of allowing the user to select whether to return the channel or automatically returning the program will be described.

The error correction unit 3 or the error detection unit 22 sends a signal indicating that a predetermined number of uncorrectable errors has not occurred within a predetermined period of time.
Output to Then, the system controller 13 obtains the video information or the audio information of the notification of the program change to the user from the memory 12 and outputs the information to the display control unit 9 or the audio decoding unit 11 so that the program can be returned. The user can be notified by video or audio. For example, if the transition is within the BS digital broadcast, it is necessary to continue to detect the error occurrence status of the program before the program transition even after transitioning to the same program, so that two BS tuners must be provided. In some cases.

On the displayed notification screen, the user can select a program change using a remote controller or the like. When a process of returning to the program before the program shift is selected by a remote controller or the like, a program change request signal is supplied from the remote controller to the system controller 13 and the program is switched and displayed / recorded.

In this case as well, a notice of channel change is displayed.

(EPG display of program transition history at the time of program recording) Next, at the time of reproduction, the program transition history at the time of program recording is displayed in EP.
A method of displaying with G will be described.

When the system controller 13 changes the demultiplex processing at the time of recording, the changed information such as changed program information and time information is stored in the memory 12.
After the recording is completed, the data in the memory 12 is acquired by the system controller 13, supplied in the order of the transport decoding unit 10 and the recording processing unit 7, and recorded in the recording processing unit 7 together with the change information. When the recorded program is reproduced, the EP of the program recorded by a remote controller or the like is used.
When the G display is selected, the system controller 13 acquires the change information from the recording processing unit 7 and supplies the change information to the display control unit 9 so that the change information such as the program number, broadcast date and time, and image quality information of the recorded program is shown in FIG. It can be displayed in EPG as shown. In FIG. 5, program 2 is temporarily switched to terrestrial digital broadcasting (SD: standard image) during the recording of BS digital broadcasting (HD: high-definition image), and the reception state is improved again. (HD: high-quality image).

It should be noted that the system controller 13 may create EPG data in the memory 12 in advance from the acquired program information data and display it. By doing so, the EPG can be displayed more quickly.

Further, in this embodiment, a case has been described in which the reception state of the satellite digital broadcast is deteriorated and the program cannot be viewed. Conversely, if the receiving condition of terrestrial digital broadcasting deteriorates and you cannot view it,
/ EPG of CS digital broadcasting is displayed.
Also, even in the case of satellite digital broadcasting, EPG may be displayed even in the case of satellite digital broadcasting in the case where it cannot be received at high quality but can be viewed at low quality due to hierarchical coding. .

As described above, the EPG of the currently receivable program is automatically displayed to the user, so that the display of the warning does not continue to be displayed, and the user can easily display another receivable program. Can be selected and viewed.

In the present embodiment, an example is described in which two tuners for BS and terrestrial digital are provided, but both BS / CS digital tuners and CAT are used.
V is also viewable, if the viewable broadcast EPG
May be displayed.

The signals supplied to the terminals 50 and 51 are not limited to digital broadcasting, but may be analog broadcasting as long as electronic program information can be obtained.

FIG. 6 shows another embodiment of the present invention. In this embodiment, a BS digital broadcast signal or a CS digital broadcast signal is supplied to a terminal 50, and a terrestrial analog broadcast signal is supplied to a terminal 5.
6 is an example of a broadcast receiving device when supplied to a broadcast receiver 6;

The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

The transport decoding unit 10 performs a demultiplexing process and converts the video signal into a video decoding unit 8.
Then, the audio signal is output to the terminal I of the selection processing unit 20 via the audio decoding unit 11. The demodulation unit 18 includes the tuner unit 1
A video signal or an audio signal is detected from the signal input from 7, and the demodulated signal is output to the video / audio reproduction unit 19. The video / audio reproduction unit 19 performs an amplification process or the like and outputs a video signal to the display control unit 21 and an audio signal to the terminal II of the selection processing unit 20.

When a selection signal from a remote controller or the like is input to the system controller 13, the system controller 13 supplies the selection signal to the display control unit 21 and the selection processing unit 20.

The display control section 21 is a system controller 1
3 is controlled by the selection signal from the terminal 3 and selects one of the two input video signals and outputs the selected signal to the terminal 52. The selection processing unit 20 is also controlled by a selection signal from the system controller 13 in the same manner.
One of the two audio signals is selected and output to the terminal 53.
