Description

  The present invention relates to a broadcast receiving apparatus such as a television receiver and a broadcast recording apparatus for recording a received video signal.

  Some broadcast receivers such as television receivers and mobile phone terminals have a correspondence between a numeric value such as a channel numeric key number and a broadcast radio wave, and receive the broadcast radio wave associated with the received numeric value. There is something to do. In these broadcast receivers, when the viewing location changes due to moving or moving on the vehicle, or when receiving based on the numerical value associated with the broadcast radio wave received with weak electric field strength, the received electric field strength of the broadcast radio wave May be below the viewable threshold. In addition, when a broadcast wave reception channel is changed or added, a previously viewable broadcast may not be viewable.

  FIG. 11 to FIG. 13 are diagrams illustrating an example in which an abnormality of the reception state is displayed on the screen on an OSD (On Screen Display) in a conventional television receiver. FIGS. 11, 12, and 13 are examples of OSD displays when the received electric field intensity of broadcast radio waves is below a level suitable for viewing, below a level that can be viewed, and below a level that can be detected as a radio wave.

  Therefore, in Patent Document 1, when reconnection to a power source is detected and it is further determined that there has been a change in the signal content of the received broadcast radio wave and / or the received electric field strength, notification information is displayed to the user and the user moves. When there is, the user is prompted to update the association between the numerical value and the broadcast radio wave.

  In the broadcast receiving apparatus having the above-mentioned association, a broadcast radio wave that can be received is detected (so-called channel search) prior to the start of viewing, and the detected broadcast radio wave is associated with the numerical value. Therefore, even when the detection is not performed, the OSD display of FIGS. 11 to 13 may be performed. When the user sees such a display and recognizes that it is necessary to construct a correspondence, the OSD display operation guidance is opened. In the operation guidance, when the region setting is requested before the detection instruction, the detection is instructed after the region setting is performed. Thereafter, the television receiver detects receivable broadcast radio waves and performs the association.

Further, in a broadcast receiving apparatus that automatically detects broadcast radio waves, detection is performed when the viewing location has not changed or when the radio wave is temporarily shielded, and there is no correspondence between the numerical values and the broadcast radio waves. It is necessary to avoid the necessity of being updated or the detection being performed during viewing to hinder viewing. Therefore, in Patent Document 2, a broadcast radio wave is detected when it is detected that power supply has been stopped when the power is turned on, and only when the number of broadcast radio waves whose received electric field strength is below the reference electric field strength exceeds a set number By updating the attachment, it automatically responds to changes in the reception state due to moving or the like. Furthermore, in Patent Document 2, when the reception electric field strength of the broadcast radio wave having the association is automatically measured at regular time intervals, the number of broadcast radio waves whose reception electric field strength is equal to or less than the reference electric field strength is within a set range. Only by reconstructing the correspondence, the change in the reception state when it flows out from the shadow of the building or the tunnel is automatically handled.

The OSD circuit 12 switches and outputs various OSD displays to the display unit 14 instead of part or all of the broadcast video input from the TV circuit 11. The audio output unit 13 switches the broadcast audio output from the TV circuit 11 or the reproduced audio output from the recording unit 3 to output the sound. The display unit 14 switches between the broadcast video and / or OSD display output from the OSD circuit 12 and the playback video output from the recording unit 3. The display unit 14 is a liquid crystal display.

  The control unit 20 includes a CPU 21, a timer 22, a ROM 23, a RAM 24, a reception unit 25, and an operation unit 26, and is connected to each other via a bus. The CPU 21 executes the program while reading it from the ROM 23 and performs input / output with each unit, thereby functioning as a control center for the broadcast receiving device 1, the recording unit 3, the receiving unit 25, and the operation unit 26. The timer 22 is used for time measurement and recording start / end time management in the processing by the CPU 21. The ROM 23 is a read-only memory that stores programs necessary for processing by the CPU 21 and various fixed data. The RAM 24 is a rewritable memory used for storing data such as temporary data generated when the CPU 21 executes a program. The receiver 25 receives the infrared signal transmitted from the transmitter 201 of the remote controller 2. The operation unit 26 is provided to directly operate the broadcast receiving apparatus 1 on the main body side, and has channel up / down keys and other operation keys.

  The remote control 2 includes a remote control operation unit 202 for remotely performing various operations of the broadcast recording apparatus, and a transmission unit 201 that outputs an infrared signal to the reception unit 25 when the remote control operation unit is operated. The remote control operation unit 202 has remote control keys and / or channel selection buttons for setting numerical values associated with broadcast radio waves and other operation keys.

  The recording unit 3 records and records the broadcast video and broadcast audio input from the TV circuit 11 and outputs the playback video and playback audio to the display unit 14 and the audio output unit 13, respectively.

  All operations related to the broadcast recording apparatus are performed by pressing operation keys on the operation unit 26 or the remote control operation unit 202. Each operation signal is received by the CPU 21 from the receiving unit 25 or the operation unit 26 via the bus.

In terrestrial digital broadcasting, the receiving channel number and the remote control number do not match. When the remote control number is associated with the digital terrestrial broadcast wave, the user inputs the area name and the prefecture area or the zip code in advance as the area setting as described above. Thereafter, the CPU 21 detects a terrestrial digital broadcast radio wave, and obtains a remote control key ID (a numerical value for designating a remote control number to which the broadcast radio wave should be assigned) from SI (Service Information) information included in the detected terrestrial digital broadcast radio wave. The remote control number having the same numerical value as the remote control key ID is associated with the broadcast radio wave.

  When selecting the target broadcast radio wave, the user performs a setting operation using the operation key of the operation unit 26 or the remote control key or the channel selection button in the remote control operation unit 202. Thereafter, the CPU 21 controls the TV circuit 11 to select the broadcast radio wave associated with the numerical value set by the remote control key or the channel selection button.

  FIG. 4 is a flowchart showing a processing procedure for determining the reception state of the broadcast radio wave in the broadcast receiving apparatus 1 according to the present invention. The following processing is executed by the CPU 21 in accordance with a control program stored in advance in the ROM 23 of the control unit 20.

  The CPU 21 takes in the received electric field strength of the broadcast radio wave output from the terminal of the TV circuit 11 a predetermined number of times every predetermined time (S11). The CPU 21 arithmetically averages the received reception electric field intensity to obtain a numerical value representing the reception state (S12). The CPU 21 determines whether or not the reception state has deteriorated below a predetermined threshold (S13). If it is determined that the reception state has not deteriorated (S13: NO), the process returns to step S11 for reading the received electric field strength. If it is determined that the reception state has deteriorated (S13: YES), the process is terminated.

  FIG. 5 is a flowchart showing a processing procedure when the reception state of the terrestrial digital broadcast wave is deteriorated in the broadcast receiving apparatus 1 included in the broadcast recording apparatus according to the first embodiment. FIG. 6 is an explanatory diagram showing an OSD-displayed image for prompting detection of broadcast radio waves, and an OSD-displayed image for accepting whether or not to notify a screen for accepting a detection instruction. FIG. FIG. 5 is an explanatory diagram showing an OSD-displayed image and an OSD-displayed image for accepting whether to detect a broadcast radio wave (channel search). As shown in FIG. 6, the CPU 21 performs OSD display for prompting detection of broadcast radio waves (channel search), and performs OSD display for selecting whether to notify a screen for receiving a detection instruction (S21). The user is prompted by the display of FIG. 6 and operates the keys of the operation unit 26 or the remote control operation unit 202 to select whether or not to issue a notification instruction. The CPU 21 determines whether “Yes” is input (S22) or “No” is input (S22: NO, S29) on the screen of FIG. 6, and waits until either is input (S22: NO). , S29: NO).

If the CPU 21 determines that “yes” has been input (S22: YES), as shown in FIG. 7, the OSD display of the current region setting contents and whether or not to detect a broadcast radio wave (channel search) are accepted. OSD display is performed (S23). Note that if the region setting has never been accepted, the contents of the region setting at that time are not displayed.
The user is prompted by the display of FIG. 7 and selects whether or not to instruct the detection of the broadcast radio wave by operating the keys of the operation unit 26 or the remote control operation unit 202. In this case, when the user recognizes that the setting contents of the area are not displayed on the OSD display or that the area setting is not correct, “NO” is selected for the purpose of setting the area.

  The CPU 21 determines whether “Yes” is input (S24) or “No” is input (S24: NO, S32) on the screen of FIG. 7, and waits until either is input (S24: NO). , S32: NO). When “NO” is input (S32: YES), the process is shifted to step S30 for performing area setting described later.

When the CPU 21 determines that “YES” is input (S24: YES), the CPU 21 detects one broadcast radio wave (S25). Further, the remote control key ID is read from the SI information included in the detected broadcast radio wave, and the reception channel number of the detected broadcast radio wave is associated with the remote control number having the same numerical value as the remote control key ID (S26).
In this case, when a plurality of broadcast radio waves having the same remote control key ID are detected, the broadcast station of FIG. 3 assigned to the accepted area is preferentially associated with the remote control number. Even if the setting of the region has never been accepted, it is rare to detect the broadcast radio wave having the same remote control key ID repeatedly, so the received channel number of the detected broadcast radio wave Even if duplicates are duplicated, the remote control number is associated with each detection. The association is held in the RAM 24 of the control unit 20, and when the user performs a setting operation by pressing the remote control key, the reception channel number associated with the remote control number of the remote control key is set by the CPU 21. Searched. The CPU 21 obtains the reception frequency from the reception channel number and controls the channel selection for the TV circuit 11.

  The progress indicating which channel is detected and the result of detection and association are displayed as OSD as shown in FIG. 8 (S27). When the detection has been completed for all target broadcast radio waves (S28: YES), the process ends. When the detection is not finished (S28: NO). The process returns to step S25 for executing detection.

  When the CPU 21 determines that “NO” is input in step S29 (S29: YES), the CPU 21 displays the screen for performing the area setting shown in FIG. 2 by OSD (S30). The user is prompted by the display of FIG. 2 and operates the operation unit 26 or the remote control operation unit 202 to set the area. The CPU 21 performs an area setting input process on the screen of FIG. 2 and the subsequent screen (S31), and the process proceeds to step S23.

  In the broadcast recording apparatus according to Embodiment 1 configured as described above, when it is determined that the reception state of the broadcast radio wave has deteriorated, the broadcast radio wave detection is performed before the user recognizes that the apparatus has failed. And OSD display for asking a notification instruction related to acceptance of the detection instruction. When the user inputs an affirmative response to the OSD display, the OSD display for inquiring an instruction to detect the broadcast radio wave is displayed while displaying the setting contents of the received area. Further, when the user gives an affirmative response to the OSD display, broadcast radio waves are detected. At each detection, the remote control key ID of each broadcast station is read from the SI information included in the broadcast radio wave, and the detected broadcast radio wave reception channel number is associated with the remote control number. Therefore, if the reception status of the broadcast radio wave deteriorates due to movement of the viewing location or addition / change of the reception channel of the broadcast radio wave, or if the user has forgotten to detect the broadcast radio wave and cannot receive it, special detection means or a new area setting It is possible to detect broadcast radio waves without the need for terrestrial broadcasting, and to quickly and easily associate digital terrestrial broadcast radio waves with remote control numbers. This can reduce the possibility of misunderstanding.

  In the first embodiment, in step 23 in FIG. 5, the area setting content at that time is configured to be displayed in OSD, but other information related to the area setting, for example, the area setting is displayed. You may comprise so that it may display in OSD whether it received.
