Description

  The present invention relates to a technique in which a receiver that receives a broadcast from a broadcast station confirms the reception state of each channel and displays the reception state on a screen.

  In a portable broadcast receiver that can receive a broadcast while moving, the quality of the broadcast reception state changes depending on the location where the broadcast is received or the direction of the broadcast receiver.

  In general, in order to confirm the reception state, the user performs a reception operation on the broadcasting station one by one (changing the channel), and the user confirms the picture sound display and the reception status display at that time.

  Since it takes time for the decoding process until the picture sound is output after the broadcast is received, it takes time for the user to check the reception status from the picture sound.

  In addition, since user operation is required for each channel, it takes more time to check many channels.

As a related technique, there is a receiver that receives a broadcast from a broadcast station, and confirms the reception state of each channel and displays the reception state on a screen (see, for example, Patent Document 1 and Patent Document 2). ).

Release transmission and reception method of the present invention, its own device startup, when the unviewable state continues a predetermined time, and, when a user operation is performed, while the channel list is displayed on the display unit are displayed The method includes the steps of repeatedly selecting a channel in order and confirming the reception status , and displaying the reception status of each channel on a key used for channel selection operation .

Program of the present invention causes a computer to ship startup, when the unviewable state continues a predetermined time, and, when a user operation is performed, while the channel list is displayed on the display unit, to display It is characterized in that a process of repeatedly selecting a channel in order and confirming a reception status and a process of displaying the reception status of each channel on a key used for a channel selection operation are executed.

  According to the present invention, the reception status can be confirmed at high speed, and the reception status of each broadcasting station can be confirmed in a list display.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a broadcast receiver 10 in the present embodiment.

  A signal received by the antenna 11 is input to the broadcast receiving unit 12. The broadcast receiving unit 12 receives and demodulates a signal having a frequency corresponding to the channel designated by the control unit 14. The control unit 14 is a part that performs overall control processing in the broadcast receiver 10 such as reception control, decoding of received data (video, audio, etc.) and display control. The reception data output from the broadcast receiving unit 12 is decoded by the control unit 14 into video, audio, etc., displayed on the display unit 15, and presented to the audio presentation unit 16. The key input unit 13 is a part that receives instructions regarding broadcast reception from the user such as channel setting, and the input information is input to the control unit 14 and used for reception control and display control. The channel list information holding unit 17 is a part that holds channel list information used during channel selection.

  In the broadcast receiver 10, a physical channel (frequency) is assigned to a numeric key of the remote controller or the broadcast receiver 10 or a list of receivable stations is displayed on the screen so that a user can easily select a broadcast station to be viewed. It has means for registering a list of receivable channels, such as making it possible.

  As a method for creating the channel list, for example, a channel list for each region is held in the broadcast receiver 10 in advance, and a channel list for the region set by the user at the start of using the broadcast receiver 10 is used. There is a method of creating a channel list by confirming whether or not each physical channel (frequency) can be received by scanning. When a broadcast station is selected by a key operation or the like from the user key input unit 13, the broadcast receiver 10 selects a physical channel that can receive the selected broadcast station based on the channel list.

  An example of channel list information is shown in FIG. A display example of the channel list is shown in FIG.

  When this channel list is displayed by a user operation or the like, the broadcast receiver 10 confirms the reception status of the broadcasting stations displayed in the channel list behind the display of the channel list and displays it on the display unit 15. To do. This flow is shown in FIG.

  Referring to FIG. 5, the broadcast receiver 10 starts reception status confirmation triggered by the display of the channel list based on the channel list information holding unit 17 on the display unit 15 (S501). When the reception status confirmation is started, first, the physical channel number of the channel at the head of the channel list is read (S502). For example, in the case of the channel list of FIG. 3, physical channel number = 27 is read.

  Next, the read physical channel = 27 is selected (S503). After channel selection, the system waits for a time until the reception status can be determined, and the signal received by the antenna 11 is input to the broadcast receiving unit 12. The broadcast receiving unit 12 receives a signal having a frequency corresponding to the channel specified by the control unit 14 and acquires a reception status such as C / N. From the acquired reception status, the strength of the reception status is determined by threshold determination or the like (S504), and displayed on the display unit 15 together with the channel list (S505). FIG. 4 shows a display example in which the strength of the reception status is represented by the number of antennas.

  This reception status confirmation is performed in the order stored in the channel list while changing the physical channel to be selected (S506, S507). When the reception status confirmation of the last physical channel in the channel list is completed (S506 / none), the process returns to the top of the channel list (S502) to confirm reception.

  The above processing is repeated while the channel list is displayed. When the channel list display ends, for example, when a viewing broadcast station is designated by a user operation, the reception confirmation is repeated.

  According to the above-described embodiment, since it is not necessary to wait until the picture sound is displayed for confirmation of the reception state, and since there is no need for user operation to change the channel one channel at a time, the reception state can be confirmed at high speed. It can be performed. Moreover, since the reception status of each broadcasting station can be confirmed by a list display, visibility is good.

  As another embodiment of the present invention, the reception status display method is not only displayed on the channel list, but also on a key corresponding to each broadcast station used when the user selects a broadcast station. You may display. Moreover, you may display by the intensity and color of light when making the key applicable to each broadcasting station light. In addition, the reception status may be displayed not on the channel list but on a screen on which a plurality of broadcast stations are displayed simultaneously, such as a program guide.

  As yet another embodiment of the present invention, the reception status confirmation start timing is the display timing of the channel list, but a reception status confirmation start menu and key are newly provided to start reception status confirmation from the user. It is also possible when the operation is performed. Further, it may be when a reception-disabled state continues for a certain time while watching a certain broadcast, or when a broadcast receiver is activated.

  As still another embodiment of the present invention, the reception status to be displayed may be a value such as C / N, electric field strength, BER, MER itself, or a value calculated from a plurality of parameters related to these reception statuses. Alternatively, the result of judging the reception status in several stages from the value may be displayed.

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, you may perform the process which implement | achieves the function of a receiver by making a receiver read the program for implement | achieving the function of the broadcast receiver 10, and executing it. Further, the program is transmitted to another computer system by a transmission wave via a computer-readable recording medium such as a CD-ROM or a magneto-optical disk, or via a transmission medium such as the Internet or a telephone line. Also good. Further, a mode in which functions are distributed by an additional device is also within the scope of the present invention.
