Description

  The present invention relates to a television receiver, and more particularly to a television receiver capable of viewing analog broadcasting and digital broadcasting.

  At the present time, which is a transition period to digital broadcasting, television receivers capable of viewing terrestrial analog broadcasting and terrestrial digital broadcasting are on the market. Terrestrial analog broadcasting is scheduled to end in 2011, and an optimum method for dealing with changes in the broadcasting status of analog broadcasting and digital broadcasting (such as channel increase / decrease) has been proposed (see Patent Document 1).

JP 2004-222050 A

  For example, Patent Document 1 discloses a technique for performing re-search processing for all frequencies when program information (channel frequency or the like) acquired / recorded changes in advance due to moving or the like. However, it does not solve the problems associated with the termination of analog terrestrial broadcasting.

  For example, the digital television manufactured by the applicant incorporates a terrestrial analog broadcast tuner in addition to a terrestrial digital broadcast tuner and a BS / CS digital broadcast tuner. In areas where terrestrial digital broadcasting has not started, there are still many households who are still watching terrestrial analog broadcasts, and there is a survey result that the terrestrial analog broadcast end time in 2011 is less than 10%. Notifying users about waves is an urgent issue. Even when digital broadcasting is started in the above district, the conventional apparatus only turns on a notification lamp mounted on the TV, for example. For users who continue analog viewing, digital broadcasting is started in that district. There is a problem that it is difficult to determine that. In addition, it is necessary to eliminate a state in which the user does not know what action should be taken at the time of migration.

  An object of the present invention is to enable a smooth transition along with the termination of analog terrestrial broadcasting.

  In the present invention, the state where the terrestrial analog broadcast tuner is selected is detected, and at the time of detection, an “end notice message” is displayed on the screen through the message display processing unit. However, if the message is displayed every time when the above-mentioned analog broadcast channel selection is detected, it may impair the user's viewing convenience.Therefore, the time information when the message was displayed last time is retained, and a certain period (for example, 6 months) or more When a similar analog channel selection operation is performed at the time that has elapsed, a similar message is displayed again. When digital broadcasting is started in the user area, the status is detected, and a message to start digital broadcasting is displayed on the analog broadcasting screen in addition to the “Analog broadcasting end notice message”. Channel scan etc.).

  That is, according to one aspect of the present invention, a television receiver capable of viewing both digital broadcast and analog broadcast, and when the operation of selecting the analog broadcast program is performed, the analog broadcast A television receiver is provided that displays a notice message regarding the end of the broadcast. By giving a prior notice to the user, the end of analog broadcasting can be made known.

  In addition to the notice message, it is preferable to display an information message regarding the start of digital broadcasting at the receiver installation location. Thereby, it is possible to notify information related to the transition to digital broadcasting.

  In addition to the notice message, it is preferable to have a transition promoting means for urging the transition to digital broadcasting channel selection at the receiver installation location. Thereby, the transition to digital broadcasting can be performed more smoothly.

  According to another aspect of the present invention, a television receiver capable of viewing both digital broadcasts and analog broadcasts, and performs channel selection instructions to the analog modulation wave demodulation unit and the digital modulation wave demodulation unit. A digital broadcast state monitoring unit that monitors whether or not the system control unit and the digital modulation wave demodulation unit are tuned when the apparatus A is powered off. The digital broadcast state monitoring unit performs monitoring for performing a transition process to digital. A broadcast status monitoring unit, and when an operation for selecting an analog broadcast program is performed, if a channel to be tuned is found, a notice message regarding the end of the analog broadcast broadcast is included at the next analog channel selection. The system control unit for displaying a notice message selected from the message group stored in the message storage unit for storing the message on the display unit; Television receiver is provided which include a display control unit that performs control based on the instruction.

  According to the present invention, by displaying an “end notice message” on the screen every time a channel is selected for analog broadcast, the end of the analog broadcast in 2011 can be surely notified to the user. User confusion at the end of analog broadcasting can be alleviated.

  Further, by holding the time when the previous message was displayed and setting the period until redisplay, it is possible to reliably notify the user of the “end notice message” without stress.

  Further, by displaying the number of days in reverse calculation up to July 2011 in the “end notice message”, more reliable time limit information can be provided. When digital broadcasting is started in that area, the digital start message is displayed at the same time as the “end notice message”, and means such as channel scanning of the digital broadcast is provided so that the user can smoothly transition. It becomes possible.

  A television receiver according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a functional block diagram showing a configuration example of the television receiver according to the present embodiment. The television receiver A shown in FIG. 1 stores a digital modulation wave demodulating unit 1, an analog channel selection state holding unit 3, a digital broadcast state monitoring unit 5, a system control unit 7, and programs for various processes. ROM 7a, analog modulation wave demodulation unit 9, graphic drawing multiple display processing unit 11, message storage unit 11a, display device unit 15, speaker 17, remote control device (remote control device) 21, and remote control light receiving unit 19, a digital decoding processing unit 23, an audio output processing unit 25, a signal processing unit 27, and an antenna 31.

  The system controller 7 controls the analog modulated wave demodulator 9 and the digital modulated wave demodulator 1 with respect to the respective channel selection. The digital broadcast state monitoring unit 5 monitors whether there is a digital broadcast channel to be tuned to the digital modulated wave demodulation unit 1 when the device A is powered off. If a channel to be tuned is found, a message display is displayed at the time of the next analog channel selection, and digital transition processing means is provided. Messages and the like at that time are stored in the message storage unit 11a. A message is displayed on the display device unit 15 based on this message. Based on message display control from the system control unit 7, a message is displayed on the display device 15 via the graphic drawing multiple display processing unit 11. At this time, the difference (difference) between the previous state stored in the analog channel selection state holding unit 3 and the current state is observed, and if there is a difference, a new message related to the difference is issued. Thus, the system control unit 7 controls the display. The analog channel selection state holding unit 3 has a function of holding the previous state. Further, the remote control device 21 transmits a user instruction to the device via the remote control light receiving unit 19. In addition, a general timer is provided, and the occurrence time of events such as display and update can be acquired by the timer and stored in association with the event.

  FIG. 6 is a diagram showing the flow of image display of the analog signal A and the digital signal D in FIG. As illustrated in FIG. 6, the analog signal is output from the system control unit 7 to the display device 15 through the analog modulated wave demodulation unit 9, the signal processing unit 27, and the graphic drawing multiple display processing unit 11. On the other hand, the digital signal is output from the system control unit 7 to the display device 15 through the digital modulation wave demodulation unit 1, the digital decoding processing unit 23, and the graphic drawing multiple display processing unit 11.

  Hereinafter, the flow of the message display operation will be described with reference to the flowchart. FIG. 7 is a flowchart showing the flow of the first processing related to message display. At the time of analog channel selection (step S0), in step S1, it is determined whether or not an “analog broadcast end” message has been displayed before. If not displayed (N), the current display time information is acquired in step S2. Next, in step S3, for example, an analog broadcast end notice message 53 is displayed on the display screen 51 as shown in FIG. 2, and the current display time information is updated / saved in step S4, and the process is terminated (step S5).

  In the case of Y in step S1, the previous display time information and the current display time information are acquired, and in step S7, it is determined whether or not a specified time (for example, 6 months) has elapsed from the previous display time. . If it has elapsed (Y), the process proceeds to step S3. If it has not elapsed (N), the process proceeds to step S8, the display is not performed, and the process is terminated (step S5).

  In this way, if the “analog broadcast end” message has not been displayed before, or if the specified time has elapsed since the previous display time even if it was displayed before, “ “Analog broadcast end” message is displayed. Thereby, it is possible to inform the user of “end of analog broadcasting” in a confirming manner.

  FIG. 8 is a flowchart showing the flow of the second process. As shown in FIG. 8, in the process shown in FIG. 7, after the current display time information is acquired in step S12, the difference between the display time of the current display time information and the analog broadcast end time is calculated in step S13. Then, after displaying the analog broadcast end notice message + the remaining days in step S14, the processing is different in that the current display time information is updated / saved in step S15. In the process shown in FIG. 8, as shown in FIG. 3, the remaining number of days is displayed on the display screen 51 in addition to the analog broadcast end notice message based on the difference between the display time of the current display time information and the analog broadcast end time. Since it is displayed (55), the user can also obtain information on how long analog broadcasting will end.

  FIG. 9 is a flowchart showing the flow of the third process. As shown in FIG. 9, at the time of analog channel selection (step S20), it is determined in step S21 whether or not an “analog broadcast end” message has been displayed before. If not displayed (N), this time display time information is acquired in step S22. Next, in step S23, a digital broadcast start state is acquired. Next, in step S24, it is determined whether digital broadcasting has already started in the area where the receiver is installed. If the digital broadcast has not been started (N), the process proceeds to step S25, an analog broadcast end notice message (see FIG. 2) is displayed, the current display time information is updated / saved in step S26, and the process is performed in step S27. finish. If the digital broadcast has already started in step S24 (Y), the process proceeds to step S28, and an analog broadcast end notice message and a digital broadcast start guidance display 57 are displayed on the display screen 51 as shown in FIG. Next, the current display time information is updated / saved in step S29, and the process ends in step S27. A method for acquiring information related to the start of digital broadcasting will be described later (FIG. 11).

  In the case of Y in step 21, the process proceeds to step S30, and the previous display time information and the current display time information are acquired. Next, in step S31, it is determined whether or not a specified time (6 months in the example) has elapsed since the previous display time. If it has elapsed (Y), the process proceeds to step S23. If not (N), the digital broadcast start state is acquired in step S32, and it is determined whether or not digital broadcast has already started in the area where the receiver is installed in step S33. If yes (Y), a digital broadcast start guidance display is performed in step S34, and the process is terminated (step S27). If not started (N), no display is made (step S35), and the process proceeds to step S27.

  As described above, in the third process, in order to determine whether or not to perform digital broadcast start guidance display or the like by determining whether or not digital broadcasting has started in the area where the receiver is installed. , It is possible to provide easy-to-understand guidance for the user.

  10A and 10B are flowcharts showing the flow of the fourth process. As can be seen from a comparison with FIG. 9, when digital broadcasting has already started in the area where the receiver is installed (Y), a digital broadcast start switching means is provided in step S56. For example, as shown in FIG. 5, on the display screen 51, an end display, a display indicating that digital broadcasting has already started, and means for allowing the user to select whether or not to view the digital terrestrial service (Yes: 63 , No: 65) is displayed. Here, when switching to digital is instructed by a user operation in step S58, for example, digital tuning is performed using digital tuning means in step S59. If switching to digital is not selected by a user operation, the process ends in step S47.

  Also, in step S48, analog broadcast end notice message display + digital broadcast start switching means is provided, and in step S49, the current display time information is updated / saved, and in step S50, an operation for switching to digital broadcasting is performed. Thus, if Y, digital tuning is performed in step S51, and if N, the process ends (step S47).

  As described above, the fourth process is characterized in that when digital broadcasting has already started in the area, a means for switching to digital viewing is provided to the user.

  FIG. 11 is a flowchart showing a flow of a processing example for acquiring information related to the start of digital broadcasting. As shown in FIG. 11, first, when the power of the receiver is turned off in step S60, the search channel initial value is set in step S61. A channel selection process is performed in step S62, and the presence or absence of a signal is determined in step S63. As for the presence / absence of this signal, for example, is there a PAT (Program Association Table) or NIT (Network Information Table) necessary for receiving a digital broadcast that is synchronized with a digital broadcast wave modulated at a frequency specified in the channel selection process? It can be determined by checking whether or not. Note that PAT and NIT are information tables required for digital broadcast reception defined by ISO / IEC13818, and are multiplexed with digital broadcast signals. If there is a signal (Y), the process proceeds to step S66, and after holding the signal presence information, if there is no signal (N), the process proceeds directly to step S64. In step S64, it is determined whether or not the all channel search is completed. If not completed (N), the search channel is incremented (+1) in step S67, and the channel selection process in step S62 is performed. When the all channel search is completed, the process ends in step S65.

  As described above, according to the television receiver of the present embodiment, the time information at which the previous message regarding the end of analog broadcasting is displayed is retained, and the same is true when a certain period (for example, six months) has passed. When the analog channel selection operation is performed, the same message is displayed again, so that the advance notice to the user can be confirmed.

  In addition, when digital broadcasting is started in the area where the receiver is installed, the user can be prompted to shift to digital broadcasting. As a result, user confusion at the end of the broadcast is reduced, and a smooth transition to digital broadcasting is possible.

  The present invention can be used for a television receiver.
