  The tuner 22 is a device that extracts a broadcast signal of a channel designated by the control unit 38 when a broadcast signal DS transmitted from a broadcast station is input via the antenna 222. The extracted signal is output to the control unit 38.

  The decoder 26 is given when one of the digital broadcast signal received by the tuner 22 and the digital content signal inputted from the external device 50 via the external I / F 24 is given by the switching control of the control unit 38. It is a device that inputs the digital signal, decodes it, and outputs it. The OSD 262 built in the decoder 26 generates image data based on information given by the control unit 38 and outputs it to the video output unit 32 for display on the screen of the display unit 40.

  In the memory 30, information on channel selection channels, which are channels that can be selected by the tuner 22, acquired in advance by auto-scanning (setting a receivable channel for the broadcast signal DS), and an operation program for the control unit 38. Is memorized. The channel selection information is stored as a channel map 302 described later.

  The video output unit 32 is a circuit that converts the video signal decoded by the decoder 26 into a video signal that can be displayed by the display unit 40 and outputs the video signal to the display unit 40. The audio output unit 34 is a circuit that converts the audio signal decoded by the decoder 26 into an audio signal that can be output by the display unit 40 and outputs the audio signal to the display unit 40.

  The remote control receiving unit 36 is a circuit that receives various command signals transmitted from the remote control 52 via infrared rays and transmits the command signals to the control unit 38.

  The control unit 38 is a circuit that controls each unit of the apparatus based on an operation program stored in the memory 30. The remote controller 52 is a device that is operated by a user to input various commands, and is a device that transmits an infrared signal corresponding to the commands.

  Referring to FIG. 2, remote controller 52 is provided with various keys so that it can be externally operated. For various keys, a power key 522 for turning on / off the power of the television 20 and switching designation of a broadcast received by the tuner 22 (in the case of this embodiment, a channel map for a channel currently being received by the tuner 22) The forward direction key 524 and the reverse direction key 526 that are operated to specify the adjacent channel in the channel selection channel order in 302 and the broadcast received by the tuner 22 are reversely specified (in the present embodiment). An inversion key 528 operated for the purpose of “reversal” will be described later) and a numeric keypad 530 for selecting a channel number for individually switching the reception channel of the broadcast signal DS are included. The forward direction key 524 and the backward direction key 526 are operated to switch the reception channel for the broadcast signal DS in the order stored in the channel map 302 by UP / DOWN operation.

  Referring to FIG. 3, channel map 302 includes information representing the channel number of the selected channel, information representing the input path, and information representing the channel number of the corresponding channel.

  In the case of the present embodiment, the channel numbers of the channel selection channels (channel numbers are 2-1, 2-2,..., 99-99 in the case of terrestrial digital broadcasting. The channel number is 2, 3, ..., 69. For cable television broadcasting, the channel number is 1, 2, ..., 120 (or 130). In addition to information indicating the channel number of the channel (“CH” in FIG. 3 indicates that it is a channel number), information indicating the digital content input from the external device 50 (digital content input from the external device 50) Is represented by the names (-1, -2) of the external device 50. In Fig. 3, "AUX" represents the name of the external device 50. It is included. The memory 30 stores information representing the channel number of the selected channel and information representing the digital content input from the external device 50. Thereby, in this Embodiment, the external apparatus 50 will be handled as a kind of channel selection channel. These pieces of information are stored in a predetermined order by the user. As a result, the memory 30 stores information representing channels that can be selected by the tuner 22 so that the order of the channels can be specified.

  The information representing the input route is “ON AIR” in the case of information corresponding to the channel number. This indicates that the broadcast station of the broadcast signal DS is the content supply source. In the case of information corresponding to the name of the external device 50, the information indicating the input path is “AUX input”. This indicates that the external device 50 is a content supply source.

  The information indicating the channel number of the corresponding channel is information indicating which channel selection channel or digital content the channel selection channel or digital content corresponds to. For example, in the case of the present embodiment, the channel selection channel “2-1” corresponds to the channel selection channel “4-2” that is the corresponding channel.

  The channel map 302 is referred to (accessed) by the control unit 38 in order for the user to select a channel or content desired to be output to the display unit 40. Specifically, every time the forward direction key 524, reverse direction key 526, or reverse key 528 of the remote controller 52 is pressed, the control unit 38 switches and selects the channel selection channel received by the tuner 22. For example, as shown in FIG. 3, it is assumed that a channel indicated by a horizontal arrow is currently selected and received. When the user presses the forward direction key 524 in order to switch the content to be output, each time the user presses the control unit 38 switches and selects the channel to be received one by one in the downward direction in FIG. When the reverse key 526 is pressed, the selected channel to be received one by one in the upward direction in FIG. 3 is switched and controlled so that the selected channel is received each time the key is pressed. .

  Each time the inversion key 528 of the remote controller 52 is pressed, the control unit 38 selects so that the selected channel received by the tuner 22 is inverted. Specifically, each time the reverse key 528 of the remote controller 52 is pressed, the control unit 38 selects a selected channel received by the tuner 22 and another selected channel corresponding to the selected channel being received by the tuner 22 (that is, the corresponding channel). Select (Channel). As described above, which channel selection channel corresponds to which channel selection channel is specified by information indicating the channel number of the corresponding channel. FIG. 4 is a diagram showing the correspondence between channel selection channels and external inputs in the present embodiment (in this embodiment, the counterclockwise direction in FIG. The direction around is called “reverse direction”). In FIG. 4, channel selection channels connected by arrows are associated with each other. As is clear from FIG. 4, among the channels associated with each other, it is necessary to press the forward direction key 524 and the reverse direction key 526 most frequently in order to select a channel among the channels stored in the channel map 302. Is a channel.

  Each time the forward direction key 524, the reverse direction key 526, or the reverse key 528 is operated, the channel received by the tuner 22 can be reversed by referring to the channel map 302. At this time, the control unit 38 switches a signal to be supplied to the decoder 26 based on information indicating the input path (information corresponding to the selected channel). If the information representing the input path indicates "ON AIR", the decoder 26 is switched to give the output signal of the tuner 22. If the information indicating the input path indicates “AUX input”, the output is switched to give the output signal of the external I / F 24.

  After switching, the control unit 38 identifies the signal received by the remote control receiving unit 36 and refers to the information indicating the input path, and the tuner 22 receives the signal of the channel selected by the signal. The tuner 22 or the external I / F 24 is controlled so as to be received (or received by the external I / F 24). For example, when the output signal of the tuner 22 is switched, the tuner 22 is controlled to receive a broadcast signal, and when the output signal of the external I / F 24 is switched, a signal given from the external device 50 The external I / F 24 is controlled so as to accept.

  A content switching selection procedure with reference to the channel map 302 will be described with reference to the flowchart of FIG.

  When the power key 522 of the remote controller 52 is operated in step S100 (hereinafter simply abbreviated as S), the command signal resulting from this operation is given to the control unit 38 via the remote control receiving unit 36. Turn on the TV 20.

  In S102, control unit 38 reads channel map 302 from memory 30. When the channel map 302 is read, the control unit 38 controls the OSD 262 to display any of the read information. In S104, control unit 38 determines whether or not forward key 524, reverse key 526, or reverse key 528 has been operated by the user based on the input signal from remote control receiver 36. If it is determined that forward key 524, reverse key 526, or reverse key 528 has been operated (YES in S104), the process proceeds to S106. If not (NO in S104), the process returns to S104.

  At S106, control unit 38 provides a signal to be given to decoder 26 (or front end 28 depending on the channel to be selected) based on information corresponding to the channel selected by the user among the information representing the path of the input. Switch. When the signal is switched, the control unit 38 selects the selected channel, the channel (original channel) in which the tuner 22 was tuned before channel selection, and the channel associated with the selected channel. The channel number information is output to the OSD 262. The OSD 262 displays an image representing the output information on the display unit 40.

  In S108, control unit 38 determines whether or not remote control receiving unit 36 has operated power key 522 of remote control 52 based on the signal from remote control 52. If it is determined that power key 522 of remote controller 52 has been operated (YES in S108), the process ends. If not (NO in S108), the process proceeds to S104.

  An operation of the television 20 based on the above structure and flowchart will be described.

  When the power key 522 of the remote controller 52 is operated, the command signal resulting from this operation is given to the control unit 38 via the remote control receiving unit 36, so the control unit 38 turns on the television 20 (S100). When the power is turned on, the control unit 38 reads the channel map 302 from the memory 30 (S102). Now, in the channel map 302, it is assumed that the channel “2-1” is selected as indicated by the horizontal arrow in FIG. FIG. 6 is a diagram showing an image displayed on television 20 at this time.

  When the channel map 302 is read, the control unit 38 determines whether or not the user has operated the forward key 524, the reverse key 526, or the reverse key 528 based on the input signal from the remote control receiver 36 (S104). ). Here, when the user presses forward key 524 (YES in S104), the channel designated by the horizontal arrow in FIG. 3 is changed to channel “2-2” shown in the next lower column. The The control unit 38 switches a signal to be supplied to the decoder 26 based on information corresponding to the channel selected by the user among the information representing the input path. When the signal is switched, the control unit 38 displays the channel numbers of the selected channel, the original channel, and the channel associated with the selected channel (S106). FIG. 7 is a diagram illustrating an image displayed on the television 20 when the broadcast of the channel “2-2” is received as a result of the signal being switched. The channel numbers of the channel “2-2”, the original channel “2-1”, and the corresponding channel “4-3” of the channel “2-2” are displayed.

  When the signal is switched, the control unit 38 determines whether or not the power key 522 of the remote controller 52 has been operated (S108). In this case, since power key 522 of remote controller 52 has not yet been operated (NO in S108), control unit 38 determines whether forward key 524, reverse key 526, or reverse key 528 has been operated ( S104). Here, when the user presses forward key 524 (YES in S104), the channel designated by the horizontal arrow in FIG. 3 is further changed to channel “2-3” shown in the next lower column. Is done. The control unit 38 switches the signal supplied to the decoder 26 (S106). FIG. 8 is a diagram illustrating an image displayed on the television 20 when the broadcast of the channel “2-3” is received as a result of the signal being switched.

  When the signal is switched, the control unit 38 determines whether or not the forward key 524, the backward key 526, or the reverse key 528 is operated through the process of S108 (S104). Here, when the user presses forward key 524 (YES in S104), the channel designated by the horizontal arrow in FIG. 3 is further changed to channel “3-1” shown in the next lower column. Is done. The control unit 38 switches the signal supplied to the decoder 26 (S106). FIG. 9 is a diagram illustrating an image displayed on the television 20 when the broadcast of the channel “3-1” is received as a result of the signal being switched.

  When the signal is switched, the control unit 38 determines whether or not the forward key 524, the backward key 526, or the reverse key 528 is operated through the process of S108 (S104). Here, when the user presses reverse key 526 (YES in S104), the channel designated by the horizontal arrow in FIG. 3 is changed to channel “2-3” shown in the upper column. The The control unit 38 switches the signal supplied to the decoder 26 (S106). Thereafter, each time the user presses the reverse direction key 526, the processing of S104 to S108 is repeated. FIG. 10 is a diagram illustrating an image displayed on the television 20 when the channel on which the tuner 22 receives broadcast is “2-1”.

  When the screen of the television 20 is in the state shown in FIG. 10 and the signal to be supplied to the decoder 26 is switched, the control unit 38 determines whether or not the forward key 524, backward key 526, or reverse key 528 has been operated through the processing of S108. Is determined (S104). Here, when the user presses reverse key 528 (YES in S104), remote control receiving unit 36 receives an instruction to invert the channel. When remote control receiving unit 36 receives an instruction to invert the channel (YES in S104), control unit 38 switches the signal applied to decoder 26 (S106). The control unit 38 sets a channel on which the tuner 22 receives a broadcast by switching a signal to be supplied to the decoder 26. The channel to be selected is a channel in which the difference in the order of the selected channel with respect to the channel “2-1” on which the tuner 22 has received the broadcast before receiving the instruction to switch the channel is equal to the value described below. “4-1”. The value is a value obtained by rounding up or down the value after the decimal point to half of the total number of channel selection channels. As is apparent from FIG. 3, in the case of the present embodiment, the corresponding channel is predetermined for each selected channel. FIG. 11 is a diagram illustrating an image displayed on the television 20 when the broadcast of the channel “4-1” is received as a result of the signal being switched.

  As described above, according to this embodiment, the user can invert the channel by operating the inversion key 528. When the channel is reversed, the number of key operations required for channel selection can be reduced to about half by using the forward key and the reverse key together. Since the number of key operations for channel selection is reduced, if there are many channels that can be received, the channel that the user wants to watch can be easily selected without direct channel selection. This will be described more specifically with reference to FIG. FIG. 12 is a diagram illustrating a relationship between channels when 100 channels are stored as channel selection channels in the channel map. As shown in FIG. 12, when the selected channel is stored and the channel “1” is selected, the channel is switched to “49” when the reverse key is pressed. If channel "49" is to be selected using the forward direction key or the reverse direction key, it is necessary to operate the key 48 times. The television according to the present embodiment can select channel “49” by operating the key once. One key is provided for the channel selection.

  Here, the remote controller 52 is used to selectively specify the content to be output to the display unit 40. However, the forward key 524, the reverse key 526, or the reverse key 528 is provided on the front panel (not shown) of the television 20. Corresponding function keys may be provided, and instructions may be given by operating from the front panel.

  When the total number of channel selection channels is an odd number, one corresponding channel may correspond to a plurality of channel selection channels. FIG. 13 is a diagram illustrating an example of the relationship between channels when the total number of channels registered in the channel map 302 is an odd number. FIG. 14 is a diagram showing an example of the contents of the channel map when the channel shown in FIG. 13 is registered in the memory 30. As is apparent from FIGS. 13 and 14, the channel “2-1” corresponds to the channels “3-2” and “4-2”.

  When the total number of channel selection channels is an odd number, a certain channel may correspond to a channel (dummy channel) that is not actually broadcast. In this case, if the corresponding channel is a dummy channel, the channel map does not include information indicating the corresponding channel (or may include information on a predetermined character string such as “NULL”). If the corresponding channel is a dummy channel, when the user presses the reverse key 528, a sandstorm-like image is displayed on the display unit 40.

  The operation of the DVD recorder 60 based on the structure and flowchart as described above will be described.

  FIG. 19 is a diagram illustrating an image displayed on television 80 when the processes of S100 to S102 are completed. Thereafter, the control unit 72 determines whether the user has operated the forward key 524, the reverse key 526, or the reverse key 528 based on the input signal from the remote control receiver 36 (S104). Here, when the user presses reverse key 528 and remote control receiving unit 36 receives a user instruction to invert the channel (YES in S104), control unit 72 refers to content map 662 in memory 66. Thus, the channel corresponding to the channel that has been the target of content selection before receiving the instruction to invert the channel is set as the channel of content selection target. As is clear from the “corresponding channel” column in FIG. 16, in the present embodiment, the channel set after the inversion is predetermined for each channel before the inversion. The channel set after inversion is less than the decimal point with respect to half of the total number of channel selection channels when the channel order difference with respect to the channel for which the content was selected before receiving the instruction to invert the channel. Equal to the value rounded up or down. As a result, the channel designated by the horizontal arrow in FIG. 16 is changed to the channel “4-1” corresponding to the channel “2-1”. The control unit 72 causes the television 80 to display content information corresponding to the selected channel (S110). FIG. 20 is a diagram showing that the television 20 is displaying content information corresponding to the channel “4-1” as a result of the channel change. When the content information is displayed, remote control receiving unit 36 receives a signal representing the selected content from remote controller 52 (S112). As a result, the remote control receiving unit 36 receives the selection of content. When the signal is received, the control unit 72 switches the input of the decoder 74 to the HD device 64. The HD device 64 reads the corresponding content signal from the hard disk and outputs it to the decoder 74. The decoder 74 decodes the signal and outputs it to the video output unit 68. The video output unit 68 outputs the decoded signal to the television 80 (S114).

  As described above, according to this embodiment, even if there is no complicated operation, the user can sequentially display content information by operating the reverse key 528. When recording many contents broadcast on many channels, the contents that the user wants to watch can be easily selected.

  The present invention is not limited to the configuration of the above-described embodiment, and various modifications can be made. For example, a device for playing digital content is not limited to the HD device 64 or the DVD playback device 62, but is a CD- A ROM (Compact Disc Read Only Memory) reproducing device or other magneto-optical disk reproducing device may be applied. Also, the device for recording / reproducing digital content is not limited to the HD device 64 or the DVD device 2, and may be another device capable of recording / reproducing large-capacity digital data at high speed.
