Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of giving a user displeasure because a television screen is frequently subjected to blackout to display a message such as "Reception is impossible, check antenna setting and adjustment" when a receiving state of a BS antenna deteriorates due to rainfall/snowfall, storm or the like while BS digital broadcasting is viewed in the conventional television with built-in BS digital. <P>SOLUTION: A function is provided for retrieving from EPG data whether the same program as the currently viewed one is broadcasted by terrestrial waves and switching to a terrestrial channel on which the same program is broadcasted when broadcasted. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a BS digital built-in television with an EPG function.

If the reception status of the BS antenna deteriorates due to rain / snowfall, storms, etc. while watching BS digital broadcasts on a conventional BS digital built-in TV, the TV screen will be blacked out, “Cannot receive. Check the antenna settings and adjustments. Please display "message (for example, see Patent Document 1).
JP 2002-016841 A

  However, with the above method, if the reception status of the BS antenna continues to deteriorate, the TV screen will frequently black out, and each time, “Cannot receive. Check the antenna settings and adjustments.” Since such a message is displayed, the user is greatly discomforted.

  The present invention aims to alleviate the above problems.

  In order to achieve the above object, the present invention searches the EPG data for whether the same program being viewed is broadcast on the terrestrial wave, and if it is broadcast, “the same program being viewed is also broadcast on the terrestrial wave”. A message such as “Yes / No” is displayed, and if the user selects “Yes”, a function to switch to the terrestrial channel on which the same program is broadcast is provided.

  Thereby, discomfort to the user due to frequent blackouts can be alleviated, and viewing can be resumed with a simple operation.

  As described above, according to the present invention, it is possible to provide a channel selection device that detects deterioration of the reception state of the BS antenna, searches for a terrestrial channel broadcasting the program using EPG data, and switches to that channel. Thus, it is possible to obtain a useful effect of relieving discomfort to the user and resuming viewing with a simple operation.

  The present invention is a BS digital built-in television equipped with a function of detecting deterioration of the reception state of a BS antenna, searching for a terrestrial channel broadcasting the program by EPG data, and switching to that channel. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 shows a channel selection device for a BS digital built-in television. In FIG. 1, reference numeral 101 denotes a BS antenna, 102 denotes a BS tuner, 103 denotes an error correction device, 104 denotes a scramble control device, 105 denotes a multiplex data separation device, 106 denotes an MPEG playback device, 107 denotes an output processing device, and 108 denotes a television screen. It is. Reference numeral 109 denotes a control microcomputer, 110 denotes a remote controller, 111 denotes a terrestrial antenna, 112 denotes a terrestrial tuner, and 113 denotes an EPG data storage unit.

  The operation of the channel selection apparatus configured as described above will be described below. In FIG. 1, when viewing BS digital broadcasting, a signal input from the antenna 101 enters the tuner 102. The tuner 102 selects a channel frequency according to an instruction from the control microcomputer 109. The signal from the tuner 102 passes through the error correction device 103 and the scramble control device 104 and then enters the multiple data separation device 105. In the multiplex data separator 105, the video signal of the channel desired by the user is extracted in accordance with an instruction from the control microcomputer 109, and enters the output processor 107 through the MPEG playback device 106. In the output processing device 107, it is output to the television screen 108 in accordance with an instruction from the control microcomputer 109.

  In FIG. 1, the control microcomputer 109 detects the deterioration of BS antenna reception when viewing BS digital broadcasting. In FIG. 1, the EPG data acquired from the multiple data separation circuit 105 and the tuner 112 is appropriately stored in the EPG data storage unit 113 by the control microcomputer 109, and the same program as the BS digital program currently being viewed is displayed on the ground. The control microcomputer 109 can search the EPG data storage unit 113 to determine whether or not it is being broadcast.

  Next, in FIG. 1, when switching to the terrestrial broadcast when viewing the BS digital broadcast, the signal input from the antenna 111 enters the tuner 112 in accordance with the user's channel switch instruction input from the remote controller 110, and the tuner In 112, the channel frequency is selected according to the instruction from the control microcomputer 109, and after entering the output processing device 107, the output of the terrestrial broadcast is switched to the television screen 108.

  In addition, a message such as “Cannot receive. Check the antenna settings and adjustments.” Or “The program you are watching is also being broadcast on terrestrial. Do you want to switch to terrestrial? Yes / No” is displayed. Is displayed on the television screen 108 from the output processing device 107.

  By doing as described above, it is possible to detect the deterioration of the reception state of the BS antenna, search for a terrestrial channel broadcasting the program using EPG data, and switch to that channel.

  In the present invention, since the deterioration of the reception state of the BS antenna can be detected and the terrestrial channel broadcasting the program can be searched by EPG data and switched to that channel, all AVs capable of receiving simulcasting are available. Useful for equipment.

The figure which shows the structure of the channel selection apparatus of BS digital built-in television in Embodiment 1 of this invention.
