Description

  The present invention relates to a broadcast reception display device and a channel selection method.

  With the increase in the number of broadcast channels in digital satellite broadcasting and the like, it is not uncommon for the number of receivable channels to exceed 50, and the operation of selecting a desired program from these is becoming very complicated. For example, there are times when it is desired to check the back program when it is a commercial time of a program that is currently being viewed or a corner that is not of interest. In such a case, it is determined whether or not the video displayed by switching to another channel will be liked in a very short time, and if it does not like, the operation of switching to another channel is repeatedly performed ( This operation is referred to as “zapping” below). If there was a favorite program during zapping, the following steps were taken.

  1. If you find a channel you like, remember the channel number.

  2. Continue zapping to see if there is a favorite program on another channel.

  3. After completing the confirmation, switch to the channel number you like and remember the program.

  At this time, if there were multiple favorite programs, I had to remember several channel numbers. You also had to remember the priority order of which channel number you liked. For this reason, channel switching by zapping has forced viewers to perform complicated operations. Therefore, as a method for confirming the back program, Patent Document 1 discloses a proposal that can confirm program contents of a large number of channels on a capture screen.

In the above-mentioned patent document 1, a back program is displayed regardless of whether or not it likes a region different from the main screen, and if a favorite program is found, a program is selected. In the displayed back program, there is no concept of the degree of likes of viewers.
Japanese Patent Laid-Open No. 10-51709

  When zapping to find a favorite program on the back program while watching the program, if there were multiple favorite programs, all channel numbers had to be stored. For this reason, there has been a problem that a favorite program is mistaken by channel switching due to ambiguous memory. Also, it was impossible to prioritize multiple favorite programs. For this reason, when there are multiple favorite programs, it is necessary to remember the degree of likes.

Channel selection means for displaying on the first screen the video broadcast on the channel designated according to the control signal designating the channel;
Means for displaying a video broadcast on the designated channel or information corresponding thereto on a second screen different from the first screen when a control signal designating the channel is input; ,
A control signal for designating the channel is input in each case where the designated channel is changed a plurality of times, and the video broadcast on different channels is displayed on the second screen in the process of performing the plurality of times. And a means for displaying a plurality of different images set at different positions on the second screen according to the circumstances.

  In the present invention, program selection can be facilitated by simply assigning a favorite degree to a favorite program and preferentially displaying the favorite program according to the favorite degree.

  In the first embodiment, among the favorite programs, the viewer can easily find a favorite program by displaying the video of the favorite program on the capture screen having a high degree of likes on the left side of the display screen. effective.

  In the second embodiment, there is an effect that the viewer can easily determine the degree of likes by adding a color frame corresponding to the degree of likes to the capture screen.

  In the third embodiment, it is possible to check channels that have not been confirmed during zapping, and the viewer can check all the favorite programs without fail.

  Next, details of the present invention will be described in accordance with the description of the embodiments.

  FIG. 1 shows a configuration diagram of the broadcast reception display device. Reference numerals 101, 104, and 107 denote antennas, reference numerals 102, 105, and 108 denote tuners for demodulating signals received from the respective antennas, and reference numerals 103, 106, and 109 denote decoders that decode the demodulated video signals. The video signal from each decoder is output to the selector 110, and the video signal of each input system is switched and transferred to the scaler 120 and the synthesis unit 124. The scaler 120 reduces the video data and passes it to the memory control unit 121. The registration memory 122 functions as a memory for temporarily registering the capture screen, and the display memory 123 functions as a display memory for outputting the capture screen. The memory control unit 121 writes the capture screen into the registration memory 122, reads out the capture screen from the registration memory 122 according to an instruction from the system control unit 130, and writes it into the display memory 123. The capture screen read from the display memory 123 is transferred to the composition unit 124. The combining unit 124 combines the video data from the scaler 120 and the selector 110. The display 125 displays and outputs video data, and the display device may be a flat panel (liquid crystal, plasma, etc.) having a matrix electrode structure or a CRT. The system control unit 130 controls the entire system and includes a CPU and a memory. 131 is a remote controller for operating this system, and will be described in detail later. In this embodiment, a remote control is used, but an operation mode in which a touch panel is combined with a display may be used. 132 is an I / F unit that transfers a signal from the remote controller to the system control unit 130, and 133 is a bus that transfers a control signal from the system control unit 130 to each block.

A front view of the remote control 131 is shown in FIG. In FIG. 2, 201 is a signal transmission unit corresponding to a remote control operation, 202 is a cursor button for selecting a capture program, 203 is a channel up / down button for switching channels, and 204 is a capture button for capturing program video. is there. The capture button 204 captures the program by being pressed when the user likes the program, and the like degree can be set according to the number of times the capture button is depressed. That is,
Press the capture button once ... Like degree 1 (like degree: low)
Press the capture button twice ... Like degree 2 (like degree: medium)
Press capture button 3 times ... Like degree 3 (like degree: high)
Are associated with each other.

  At this time, the system control unit 130 associates the channel number with the degree of preference information and stores them in a memory (not shown) of the system control unit 130. In response to an instruction from the system control unit 130, the memory control unit 121 captures the reduced video data from the scaler 120 and writes it into the registration memory 122. Next, in order to display and output the registered capture screen, individual capture screens are read from the registration memory 122, and the order of the capture screens is rearranged and written to the display memory 123. By this process, a capture screen for display output is constructed and transferred to the synthesizing unit 124. In the present embodiment, capture screens having a high degree of likes are displayed side by side from the left side of the display screen, and the maximum number of capture screens is four.

  The number of capture screens is not limited as long as the screen ratio of the capture screens is maintained and the size is not reduced so that the visibility is not lost.

  The combining unit 124 combines the captured image from the memory control unit 121 and the received program image from the selector 110. Then, it is displayed on the display 125.

  Next, a case where zapping is performed while watching a program will be described. When watching the program of the BS digital tuner 102 and becoming a CM or the like and confirming whether the favorite program is broadcast on the back program, the channel is switched by the channel up / down button 203 in FIG. When you find a program you like, press the capture button 204 once. Then, the system control unit 130 in FIG. 1 issues a capture instruction to the memory control unit 120 and captures the capture screen. This will be described with reference to FIG. The registration memory and the display memory in FIG. 3 represent images of stored screen configurations.

  In FIG. 3a, since ch101 is liked and the capture button is pressed once, the capture screen of ch101 is stored in the registration memory 301. Since there is only one registered capture number, a capture screen is stored in the display memory 302 as shown in the figure.

  Next, in FIG. 3B, since the user likes the ch 108 and presses the capture button twice, the capture screen for the ch 108 is added to the registration memory. Since ch108 has been pressed twice for the capture button, it is rearranged and stored in the display memory in the order of priority ch108 and ch101.

  Next, in FIG. 3c, the user captures ch120 and presses the capture button twice, and the capture screen for ch120 is added to the registration memory. Since ch120 has been pressed twice for the capture button, it is rearranged and stored in the display memory in the order of priority with ch108, ch120, and ch101.

  Next, in FIG. 3d, ch130 is liked and the capture button is pressed three times, and the ch130 capture screen is added to the registration memory. Since ch130 is a capture button pressed three times, the display memory stores rearranged ch130, ch108, ch120, and ch101 in order of priority. If the number of captures exceeds four, it may be overwritten with a lower priority, or may be overwritten with an older one.

  Then, as shown in FIG. 4, a display output image 403 is obtained by synthesizing the output image 401 from the display memory rearranged and stored with the received program image 402 from the selector. Displayed in 125. Then, when an arbitrary capture screen is selected with the cursor button 202 in FIG. 2, the system control unit 130 performs channel selection control of the BS digital tuner 102 to the channel corresponding to the selected capture screen and displays the screen to the synthesis unit 124. Give instructions to stop synthesis. The BS digital tuner 102 outputs the video signal of the desired channel, displays the desired channel on the display 125, and the channel switching is completed.

  Next, an operation flowchart of the system control unit 130 will be described with reference to FIG. First, when channel switching is detected in S501, the process proceeds to S502, and it is detected whether the capture button is pressed. If the capture button 204 is not pressed, the process returns to S501. If the capture button 204 is pressed, the process proceeds to S503, and the number of times the capture button 204 is pressed is stored. The channel number received at this time is also stored together. Next, when a capture instruction is issued to the memory control unit 121 in S504, the capture screen is written in the registration memory 122. Compare the likes from the capture screens already registered in S505, read from the registered memory 122 in order from the capture screen with the highest likes in S506, and capture the capture screen from the capture screen with the highest likes to the display memory 123 in S507 Write. As a result, since the captured screen has a high favorite level, in S508, the screen captured image is read from the display memory 123 and synthesized with the received program image.

  As described above, by capturing a favorite program during zapping and displaying a capture screen with a higher degree of likes from the left side of the display screen, the viewer can reliably identify the favorite program and easily select a program. There is an effect that can be performed.

  Since the system configuration is the same as that of the first embodiment, it will be omitted. The difference from the first embodiment is that a frame is added to the capture screen and a process of changing the color of the frame according to the degree of likes is added. This will be described with reference to FIG. As in the first embodiment, the capture screens are rearranged and written in the display memory.

  After the capture screen is stored in the display memory, the frame data is overwritten so as to border the area of the capture screen. This will be described with reference to FIG. The capture screen is written at a in FIG. 7 and overwritten so as to border the capture screen at b in FIG. Here, the upper and lower ends are 10 lines and the left and right ends are 10 pixels. Returning to FIG. 6, since the degree of likes is 1 in FIG. 6 a, a color frame corresponding to the degree of likes is given. In FIG. 6b, since the degree of favorite is 2, a color frame corresponding to the degree of favorite is given. In FIG. 6c, since the degree of favorite is 2, a color frame corresponding to the degree of favorite is given. In FIG. 6d, since the degree of favorite is 3, a color frame corresponding to the degree of favorite is given.

  As described above, by attaching a color frame corresponding to the degree of likes to the capture screen during zapping, there is an effect that the viewer can easily determine the degree of likes.

  Since the system configuration is the same as that of the first embodiment, it will be omitted. The difference from the first embodiment and the second embodiment is that a hold button is added to the remote control. FIG. 8 shows a front view of the remote control according to the third embodiment provided with the hold button 701.

  In the same way as in the first embodiment, there is a case where BS digital broadcasting zapping is performed and the switched channel happens to be in a CM broadcast and the program content cannot be confirmed. At that time, when the hold button 701 is pressed, the channel number that could not be confirmed is stored in a memory (not shown) of the system control unit 130. After completing one zapping, the system control unit 130 issues a switching instruction to the unconfirmed channel number stored in the BS digital tuner 102.

  A flowchart of the system control unit 130 will be described with reference to FIG. If channel switching is detected in S801, the process proceeds to S802 to detect whether the hold button is pressed. If it is not pressed, the process returns to S801, and if it is detected that the button is pressed, the channel number when it is pressed is stored. If the channel operation is performed in S804, since the zapping has not been completed yet, the process returns to S801. If channel switching is not detected in S804, it is considered that zapping has ended, and the process proceeds to S805. In S805, a process of switching to an unconfirmed channel number is performed.

  After the above flowchart, it is possible to set the degree of preference of the channel that has not been confirmed by performing the same processing steps as the capture button press in S502 and subsequent steps in the flowchart of FIG.

  As described above, it is possible to check a channel that has not been confirmed during zapping, and the viewer can avoid missing a favorite program.
