  The present invention relates to a digital broadcast receiving device and a channel selection method for the digital broadcast receiving device, and more particularly, to a digital broadcast receiving device and a digital having a function of receiving and displaying a data broadcast transmitted superimposed on radio waves of the digital broadcast The present invention relates to a channel selection method for a broadcast receiving apparatus.

  The channel selection operation, which is a switching operation of the broadcast channel received by the television receiver, includes a method of directly selecting a channel with a numeric key such as a remote controller as a remote operation device, and a channel +/- (up / down) of the remote controller. There are a sequential channel selection method in which the channel number is increased / decreased with keys, and a channel selection method by assigning channels to numeric keys on the remote controller.

  By the way, in recent television receivers, various broadcasts are received by one TV receiver such as BS (Broadcasting Satellite) digital broadcast, CS (Communications Satellite) digital broadcast, and terrestrial digital broadcast. Things that can be done are increasing.

  In the case of such a television receiver, the channel selection operation using the channel +/- (up / down) key of the remote control is performed by the user operating the channel +/- (up / down) key of the remote control. Each channel of the digital broadcasting television (011ch, 021ch,...) And each channel of the BS digital broadcasting television (101ch, 102ch, 103ch,...) Are continuously selected.

  However, digital broadcasting has a large number of channels, and there are multiple types of broadcasting media such as “TV”, “Radio”, and “Data”, and channel selection operations are performed using the channel +/− (up / down) keys on the remote control. Therefore, the channel selection operation becomes complicated when the target channel is away from the currently selected channel, and smooth channel selection to the target channel becomes difficult.

  Further, in order to solve the above-mentioned problems, the remote control, which is a remote control device, has a “terrestrial” key for selecting a terrestrial television broadcast as a broadcast key for selecting a broadcast and a “digital” for selecting a BS digital broadcast. A BS key is provided, and a “TV” key for selecting a television broadcast as a media key for selecting each media, a “radio” key for selecting a radio broadcast, and “data” for selecting an independent data broadcast. ”Key, and after selecting the broadcast key, the media key is selected, and channel selection is performed with the channel up“ + ”key / channel down“ − ”key in the media in the broadcast service. Patent Literature 1 discloses a channel selection operation device in which a channel in each medium is assigned to a numeric key of a remote control so that a channel can be selected. It is.

By the way, digital broadcast data broadcasting can be accompanied by television broadcasting and radio broadcasting programs in addition to independent data broadcasting of media.
For example, when a user presses a data broadcast button on a remote control of a digital broadcast receiving device on a television broadcast channel, the first data broadcast program screen intended by the data broadcaster is displayed on the display device.

After the first data broadcast program screen is displayed on the display device, the user moves from the first data broadcast program screen to another screen by operating a cursor key, a determination key, or the like of the remote controller.
The transition from the first data broadcast program screen to another screen is also a button provided by the broadcaster for transition to each screen in advance, and the destination where the transition can be made is determined by the content of the data broadcast.

Further, at this time, not only the transition from the first data broadcast program screen to another screen but also the broadcaster can arrange buttons to select other channels.

  However, when data broadcasting content to be selected for such another channel is displayed on the display screen of the display device and the channel is selected by selecting a button, for example, the first television broadcast Ach is selected. If you select a button to perform operations that involve channel selection in the content of the data broadcast, you will notice that the user has selected another channel, regardless of whether or not you are aware Select the channel AAAA.

  Thereafter, for example, if the user tries to select a channel by using the channel up “+” key / channel down “−” key of the remote controller, the base point to be selected is not Ach but the channel currently being viewed. Because it becomes AAAch, channel selection of the remote control is not performed for Bch when channel up / down is performed with “+” key / channel down “−” key of remote control with respect to Ach. Channel selection may be performed for BBBch when channel is up / down with “+” key / channel down “−” key.

  The user didn't realize that he was tuned to AAAch, or was aware that he was tuned to AAAch at first, but AAAch had the sensation of being a branch of Ach. In this case, when the user feels uncomfortable in selecting the channel to BBBch, and the user desires to select the channel to Bch, the user's intended operation is not performed.

  Furthermore, if the user selects a digital broadcast receiver with a channel selection method that selects the media key after the user selects the broadcast key on the remote control, the channel selection from the content of the data broadcast skips the media. When it happens, the media will change.

  For this reason, in the digital broadcast receiving apparatus that allows channel selection in the respective media to be selected by channel selection with the channel up “+” key / channel down “−” key on the remote control or numeric keys on the remote control, When you want to select a channel in the media before the channel selection from the content of the data broadcasting, specify the channel directly or switch the media once, and then the channel up “+” key / channel down on the remote control It was necessary to select a channel using the “−” key, or to select a channel using a channel assigned to the numeric keys of the remote controller, and it took time and effort to select a channel using the remote controller.

  Therefore, in view of the above problems, the present invention is a channel selection instruction in which channel selection performed at the time of the next channel selection instruction is directly performed on the digital broadcast receiver from the remote operation means by the user. When the instruction is given by the channel selection instruction from the data broadcast content, the channel selection instruction is given to the digital broadcast channel selection means based on the channel, broadcast service, and broadcast media before the channel selection from the data broadcast content.

FIG. 3 is a diagram showing an example of a BML document accompanied by a channel selection operation used in data broadcasting in the digital broadcast receiving apparatus according to the embodiment of the present invention. FIG. 4 is a digital broadcast receiving apparatus according to the embodiment of the present invention. It is a figure which shows the BML document display screen displayed on a display means corresponding to each element of the BML document by the data broadcast display browser part in an apparatus.
Here, it is assumed that a BML (Broadcast Markup Language) document 8 accompanied with a channel selection operation used in data broadcasting as shown in FIG. 3 is sent to the digital broadcast receiver 2.

  On the BML document display screen 50A of the video output unit 5, as shown in FIG. 4, a “stock” button 51A for selecting stock information, a “weather” button 51B for selecting weather forecast, and news are selected. A “news” button 51C for selecting, a “to AAAch” button 52A for selecting the channel to AAAch, a “to BBBch” button 52B for selecting to the BBBch, and a television screen 53 with a reduced display area are displayed.

Here, the “to AAAch” button 52A displayed on the BML document display screen 50A of the video output unit 5 shown in FIG. 4 is defined as follows.
<P id = “AAA”
onclick = "senkyoku1 (); ..."
style = ”left: 300 px; top: 300 px; width: 60 px; height: 50 px;
nav-index: 3; nav-down: 4;
To AAAch </ p>

  In particular, onclick = “senkyoku1 ()” operates senkyoku1 () when clicked. It means that.

Furthermore, Senkyoku1 () is
function senkyoku1 () {
browser. epgTune ("arib-dc: // AAAA");
}
When the “To AAAch” button 52A displayed on the BML document display screen 50A of the video output unit 5 shown in FIG. 4 is clicked, epgTune () is executed. It means that.

  When epgTune () is executed by a script function, it selects a broadcast service (channel) as an argument.

  That is, when the “To AAAch” button 52A displayed on the BML document display screen 50A of the video output unit 5 shown in FIG. 4 is clicked, the operation is to select the channel to AAAch.

  While presenting this data broadcast, if the remote controller 4 moves the cursor to the “Go to AAAch” button 52A displayed on the BML document display screen 50A of the video output unit 5 and the user presses the enter key 45 on the remote controller 4. The remote controller receiver 23 of the digital broadcast receiver 2 receives a signal that the enter key 45 of the remote controller 4 is pressed, and the signal “determine key” received by the remote controller receiver 23 of the digital broadcast receiver 2 is the digital broadcast. The data broadcast display browser section 26 of the receiver 2 is notified, and the data broadcast of the digital broadcast receiver 2 indicates that the signal “determine key” from the remote control receiver section 23 has been pushed on the “to AAAch” button 52A. Analysis is performed by the display browser unit 26.

  The data broadcast display browser unit 26 of the digital broadcast receiver 2 notifies the channel selection determination unit 21 of the digital broadcast receiver 2 that the channel selection operation written in the BML document has been performed as an analysis result. .

  Then, the channel selection determination unit 21 of the digital broadcast receiver 2 selects a channel by pressing the enter key 45 of the remote controller 4 on the “to AAAch” button 52A displayed on the BML document display screen 50A of the video output unit 5. It is determined that the instruction is “a channel selection instruction from data broadcasting content”.

  Thereafter, the channel selection determination unit 21 of the digital broadcast receiver 2 issues a channel selection instruction to the digital television broadcast tuner unit 20, and the channel selection storage unit 22 of the digital broadcast receiver 2 indicates “from the contents of the data broadcast”. It is memorized with the channel that it was “channel selection instruction”.

  If the user selects a channel with the channel up “+” key 42a / channel down “−” key 42b of the remote control 4 instead of the enter key 45 of the remote control 4, the data broadcast of the digital broadcast receiver 2 is performed. In the display browser unit 26, the channel up “+” key 42a / channel down “−” key 42b of the remote controller 4 are analyzed as being not described in the channel selection instruction for data broadcasting. The station determination unit 21 determines that the instruction is “direct channel selection instruction directly received by the user with respect to the receiving device”, and then instructs the digital television broadcast tuner unit 20 of the digital broadcast receiver 2 to select a channel. In the channel selection storage unit 22 of “the channel selection instruction to be performed directly on the receiving device by the user” And stored along with the Yan'neru.

Next, an example of a processing flow for instructing channel selection will be described with reference to FIGS.
FIG. 5 is a flowchart for explaining the channel selection instruction processing of the digital broadcast receiver in the digital broadcast receiver according to the embodiment of the present invention.
First, the user gives a channel selection instruction (step S101).
The channel selection instruction here may be either “a channel selection instruction performed directly by the user with respect to the receiving device” or “a channel selection instruction from the content of the data broadcast”.

  Then, the channel selection determination unit 21 of the digital broadcast receiver 2 determines whether data broadcasting is currently being activated (step S102).

  If data broadcasting is currently being activated (“YES” in step S102), whether the channel selection determination unit 21 of the digital broadcast receiver 2 is trying to select a channel by the operation described in the data broadcast content. Is determined (step S103).

  Here, when channel selection is to be performed by the operation described in the data broadcast content (step S103 “YES”), that fact is designated as “channel selection instruction from the data broadcast content” before the channel selection instruction. The channel is stored in the channel selection storage unit 22 of the digital broadcast receiver 2 together with the channel (step S104), and then the digital television broadcast tuner unit 20 of the digital broadcast receiver 2 selects the channel (step S105).

  Further, when data broadcasting is not currently activated (“NO” at step S102), when the channel selection operation itself is not described, or when channel selection is not performed by the operation described in the data broadcast content (Step S103 “NO”), since it is not the channel selection from the data broadcast content, it is stored in the channel selection storage unit 22 of the digital broadcast receiver 2 together with the channel as “selection instruction to be performed directly by the user with respect to the receiving device”. In addition, the count value N = 1 is set (step S106).

  Next, the channel selection determination unit 21 of the digital broadcast receiver 2 determines from the channel selection memory whether the previous channel selection instruction was the channel selection instruction described in the data broadcast content (step S107).

  Here, if the previous channel selection instruction is not the channel selection instruction described in the data broadcast content (step S107 “NO”), the designated channel is selected as it is (step S105).

  If the previous channel selection instruction is the channel selection instruction described in the data broadcast content (“YES” in step S107), the current channel is “channel selection instruction from the data broadcast content”. Next, the previous channel selection channel determines whether the previous channel selection instruction is a direct channel selection instruction (step S108).

  Here, if the previous channel selection instruction is a direct channel selection instruction (step S108 “YES”), the channel selection is “a channel selection instruction that is directly performed by the user on the receiving device”. ”, The channel selection instruction is made based on the previous channel selection channel that was directly performed, and the channel selection is performed (step S109).

If the previous channel selection instruction is not a direct channel selection instruction (“NO” in step S108), the channel selection is “channel selection instruction from data broadcasting content”. Next, the count value N = N + 1 is set (step S110), and then it is determined whether the previous channel selection instruction is a direct channel selection instruction (step S108).
Then, the channel that has been directly selected is searched, the channel selection is instructed based on the channel, and the channel is selected.

Next, one broadcast service is selected from the plurality of broadcast services, one of the plurality of broadcast media is selected from the selected broadcast services, and one of the plurality of channels in the selected broadcast media is selected. An example of the processing flow for the channel selection instruction of the digital broadcast receiving apparatus that can select “N” will be described with reference to FIGS. 2 and 6.
In particular, here, the broadcasting service is described as “terrestrial digital broadcasting”, “BS digital broadcasting”, “110 longitude CS digital broadcasting”, and the broadcasting media are “television”, “radio”, “data”. explain.

FIG. 6 shows the selection of the digital broadcast receiver in which the third selection means of the remote control means in the digital broadcast receiving apparatus according to the embodiment of the present invention manages and stores the channel separately for each broadcast service and broadcast media. It is a flowchart explaining the process of an instruction | indication.
First, a channel is assigned in advance to each broadcast media of each broadcast service to the numeric keys 43 of the remote controller 4 shown in FIG. 2, and the channel up “+” key 42a / channel down “−” of the remote controller 4 is assigned. "Key 42b" can also select a channel in each broadcast media of each broadcast service in order.

  For example, assume that the user tries to select a channel assigned to the numeric key 43 using the numeric key 43 of the remote controller 4 (step S201).

  Then, the current broadcast service and broadcast media are stored in the channel selection storage unit 22 of the digital broadcast receiver 2 (step S202).

  Next, the channel selection determination unit 21 of the digital broadcast receiver 2 determines whether data broadcasting is currently activated (step S203).

  If the data broadcasting is currently activated (step S203 “YES”), whether the channel selection determination unit 21 of the digital broadcast receiver 2 is going to select a channel by the operation described in the data broadcasting content. Is determined (step S204).

  Here, when channel selection is to be performed by the operation described in the data broadcast content (“YES” in step S204), this is indicated as “channel selection instruction from the data broadcast content” before the channel selection instruction. The channel is stored in the channel selection storage unit 22 of the digital broadcast receiver 2 together with the channel (step S205), and then the digital television broadcast tuner unit 20 of the digital broadcast receiver 2 selects the channel (step S206).

  In addition, when data broadcasting is not currently activated (step S203 “NO”), or when channel selection is not performed by the operation described in the data broadcasting content (step S204 “NO”), the data broadcasting content Therefore, the channel is stored in the channel selection storage unit 22 of the digital broadcast receiver 2 together with the channel as a “channel selection instruction directly performed by the user to the receiving device”, and the count value N = 1. (Step S207).

  Next, the channel selection determination unit 21 of the digital broadcast receiver 2 determines whether or not the previous channel selection instruction is the channel selection instruction described in the data broadcast content from the channel selection memory (step S208).

  Here, if the previous channel selection instruction is not the channel selection instruction described in the data broadcast content (“NO” in step S208), the current channel is “the channel selection instruction performed directly by the user on the receiving device”. As is the case with the previous step, the channel designated by the fact that it is “the channel selection instruction to be performed directly on the receiving device by the user” is selected (step S206).

  If the previous channel selection instruction is a channel selection instruction described in the data broadcast content (“YES” in step S208), the current channel is “channel selection instruction from the data broadcast content”. Next, the previous channel selection channel determines whether the previous channel selection instruction is a direct channel selection instruction (step S209).

  Here, when the previous channel selection instruction is a direct channel selection instruction (step S209 “YES”), the broadcast service and broadcast media of the previous channel selection channel performed directly in this previous channel selection channel. It is determined whether or not the broadcast service and broadcast media of the currently selected channel match (step S210).

  Here, if the broadcast service / broadcast media of the previous channel selection channel matches the broadcast service / broadcast media of the current channel selection channel (“YES” in step S210), the last time the direct selection was made. A channel selection instruction is made based on the channel selection channel, and a channel is selected (step S211).

Here, if the broadcast service / broadcast media of the previous channel selection channel does not match the broadcast service / broadcast media of the current channel selection channel (“NO” in step S210), the last time the direct selection was made. The broadcasting service of the selected channel, the digital broadcasting receiver 2 is switched to the broadcasting media, and the channel assignment of the numeric key 43 of the remote controller 4 and the channel up “+” key 42a / channel down “−” key 42b is also the current broadcasting service, Switching from the broadcast media to the previous broadcast service or broadcast media (step S212).
Thereafter, the channel selection instruction is made based on the previous channel selection channel that was directly performed, and the channel selection is performed (step S211).

If the previous channel selection instruction is not a direct channel selection instruction (“NO” in step S209), the channel selection is “channel selection instruction from data broadcasting content”. Next, the count value N = N + 1 is set (step S213), and it is then determined whether the previous channel selection instruction is a direct channel selection instruction (step S209).
The determination is made until a channel that has been directly selected is found.

Next, at the time of channel selection instruction, whether the previous channel selection instruction was a channel selection operation performed from within the data broadcasting content is displayed on the display unit of the digital broadcast receiver, the display unit of the remote control unit, or the display screen of the display unit. An example of notifying will be described with reference to FIGS.
