  Hereinafter, a hard disk drive (HDD) / optical disk apparatus integrated television receiver will be described as an example of a television receiver. FIG. 1 is a block diagram showing a configuration of a television receiver 10 integrated with an HDD / optical disc apparatus and its peripheral devices. The HDD / optical disk device integrated television receiver 10 is connected to an external device 12 typified by an image / audio recording device such as a set top box (STB) such as cable television or satellite broadcasting, or a video deck. Further, the HDD / optical disk device integrated television receiver 10 can be operated by a remote controller 13. Hereinafter, a BD (Blu-ray Disc) will be described as an example of the optical disc.

  The HDD / optical disk device integrated television receiver 10 demodulates and digitizes a television broadcast signal received by an antenna 15 and compresses video / audio data received from the tuner 16 or the external device 12 in accordance with MPEG2 or the like. An image / audio compression / decompression unit 17 for encoding or decompressing / decompressing compressed image data reproduced by the HDD recording / reproducing unit 18 or BD / DVD recording / reproducing unit 19, and a compression received from the image / audio compression / decompression unit 17 The recorded video / audio data is recorded on the HDD, and the HDD recording / reproducing unit 18 for reproducing the data recorded on the HDD, and the BD into which the compressed video / audio data received from the video / audio compression / decompression unit 17 is inserted. BD / DVD recording / playback unit 19 for recording data and playing back data recorded on a BD, and various setting values are displayed. An OSD (On Screen Display) unit 20 that can be set while being displayed on a part of the device 11, an image output unit 21 that converts an image signal from the OSD unit 20 into an analog signal, and outputs the analog signal to the display unit 11. The audio signal from the decompression unit 17 is converted into an analog signal and output to the display unit 11, the memory 23 including a ROM or a RAM, the remote control reception unit 24 that receives a signal from the remote controller 13, and the external device 12. An external I / F 25 to be connected and a control unit 26 for controlling each part of the HDD / optical disk apparatus integrated television receiver 10 are provided.

  In addition, the control unit 26 searches for a program based on a program genre or keyword set by the user, arranges programs reflecting the user's preference in order, and sets a recommended rank, and selects a high-ranked program. And control such as recording.

  Specifically, using information other than the image / audio data in the broadcast data (program genre, viewing age limit, image quality, audio system, program name, program description, etc.), the priority is set in advance in the desired information order by the user. If set, the control unit 26 searches for the program currently being broadcast, and determines the recommended rank by searching for the program based on the priority set by the user. In order to determine the recommended order, first, a program having information matching the high priority information set by the user is ranked high, and secondly, programs having the same priority information are Regardless of the number, the programs have the same rank, and thirdly, programs having different priority information are comprehensively determined as programs having higher different priorities.

  As a result of the above determination, if there is one program with the first recommended ranking, the control unit 26 selects the program, and if there are a plurality of programs with the first recommended ranking, the user selects from among them. And control to select the selected program. Note that if there is one program with the first recommended order, the user may be prompted to select whether or not to select the program before selecting it.

  Further, when there is one program with the recommended ranking of 1st and 2nd, the control unit 26 selects the program with the recommended ranking of 1st as described above, and the recommended ranking is 2 You may make it instruct | indicate the recording of the program of a position. By recording, even if the recommended ranking is low, you can watch it later. Note that before selecting the program with the first recommended order, the user may be prompted to select whether or not to select the program, and the recording of the program with the second recommended order is instructed. The user may be prompted to select whether or not to record the program.

  In addition, when there is one program having the first recommended rank and there are a plurality of programs having the second recommended rank, the control unit 26 selects the program having the first recommended rank as described above. In addition, the user may be prompted to select from programs with the second recommended rank, and may be instructed to record the selected program.

  In addition, when there are a plurality of programs having the first recommended rank, the control unit 26 prompts the user to select from among the programs as described above, and selects the program for which the selection operation has been performed. May be controlled so as to prompt the user to select a program that was not selected from among the programs ranked No. 1 and to instruct recording of the selected program. By recording, programs that were not selected can be viewed later.

  The recording destination instructed by the control unit 26 is the HDD of the HDD recording / reproducing unit 18 selected by the user or the optical disc of the BD / DVD recording / reproducing unit 19. If the external apparatus 12 includes a recording medium such as an HDD or an optical disk, the recording medium of the external apparatus 12 may be selected as a recording destination.

  Hereinafter, an embodiment relating to program search in the HDD / optical disk apparatus integrated television receiver 10 will be described. When the user tries to search for a program, first, a “priority setting menu” is selected from the menu screen. The priority setting menu is a menu for inputting a search condition when searching for a program, that is, a menu for inputting a priority item when determining a recommended order.

  FIG. 2 shows an example of the priority setting menu screen. The screen 30 is a screen at the time of starting the priority setting menu. In this example, priority levels 1 to 3 can be set in descending order of priority. Then, it is in a state where the priority 1 item setting with the cursor 31 can be input.

  When the enter key is pressed in the state of the screen 30, the screen 40 of FIG. 3 is displayed, and a list of candidates for setting items of priority 1 with the cursor 31 is displayed. On the screen 40, the cursor 41 is on “free word” which is a candidate for item setting.

  When the enter key is pressed in the state of the screen 40, the item setting portion of the priority 1 is set to free word, and a screen (not shown) for inputting the free word is displayed. A desired word is input using the assigned general input method. For example, when “Hanshin” is input and the enter key is pressed, the screen 50 in FIG. 4 is displayed. On the screen 50, the content that Hanshin is included in the free word is set as the priority 1, and the cursor 51 is in a position where the item of the priority 2 can be set.

  When the enter key is pressed in the state of the screen 50, the priority 2 item setting can be set in the same procedure as described above. The screen 60 of FIG. 5 shows a case where “genre” is selected in the priority 2 item setting, a list of candidates for detailed settings of priority 2 is displayed, and the cursor 61 is placed on “baseball”. Is in a position.

  A screen 70 in FIG. 6 shows a state in which similar operations are repeated and the priority level 3 is input. On the screen 70, the cursor 71 is positioned on “setting completed”. When the enter key is pressed in this state, the priority setting is completed, and this setting becomes effective until the next setting is changed. On the other hand, when the cursor 71 is moved to “Clear settings” and the enter key is pressed, the contents set above are erased and the screen returns to the state of the screen 30 in FIG.

  In order to execute the program search based on the priority setting contents that are valid as described above, the recommended program key of the remote controller 13 is pressed. The operation of the HDD / optical disk device integrated television receiver 10 when the recommended program key is pressed will be described below.

  FIG. 7 is a flowchart showing the program search operation in the HDD / optical disk apparatus integrated television receiver 10. Here, it is assumed that the settings are valid with the contents of the priorities 1 to 3 shown on the screen 70 in FIG. In this state, when the recommended program key is pressed, in step S10, the control unit 26 acquires information other than the image / audio data of the currently broadcast program of each channel.

  For example, in the case of Europe, since broadcast data is configured in accordance with the European standard (EN) created by the European Telecommunications Standards Institute (ETSI), the above information can be obtained from various data storage locations. . For example, program genre, viewing age restriction, video, and audio data are extracted from TS (Transport Stream (ETSI EN 301 192)) in which video, audio, and various data of the program are stored. Then, PMT (Program Map Table) and EIT (Event Information Table) defined by SI (Service Information (ETSI EN 300 468)) are confirmed in order to know the detailed information from the extracted data.

  FIG. 8 shows an example of the PMT, and FIG. 9 shows an example of the EIT. The video quality is determined from the service_type in the service descriptor in the EIT, whether it is SD (standard image quality) or HD (high image quality). The audio system is determined from the Stream_type and AC-3_audio_stream_descriptor in the PMT. The parental_rating_descriptor of the program is used, and the genre of the program is determined from the content_descriptor in the ETI.

  Since these pieces of information are contents that are generally confirmed when displaying a banner or EPG (electronic program guide) displayed at the time of channel selection, they can be acquired by providing a function that can display a banner or EPG.

  Returning to FIG. 2, the description will be continued. The process proceeds from step S10 to step S11, and the acquired information is set as a search target, that is, a program that is currently being broadcast is set as a search target, and a program including at least one of the priorities 1 to 3 set by the user is extracted. . Here, for example, it is assumed that programs A to D as shown in a list in FIG. 10 are extracted.

  Next, it progresses to step S12 and the recommendation order | rank of extracted program AD is determined. In this determination, as a first stage, a program having information that matches information with high priority is ranked high. “Hanshin”, which has the highest priority level 1 and is included in the program name and description, is programs A, B, and C. Program D has priority levels 2 and 3, but “ "Hanshin" is not included. Therefore, if it is determined that the program D is in the recommended ranking of 4th, and the rank in the first stage is expressed using an inequality sign, the programs A, B, C> program D are obtained. The larger side of the inequality sign indicates higher ranking.

  Next, as a second stage, programs having the same priority information are given the same rank regardless of the number of information. “Hanshin” with priority 1 is included in program A, four in program B, and one in program C, but the number is not considered here. Therefore, the ranking up to the second stage is the same as the first stage, and programs A, B, C> program D are satisfied.

  Next, as a third stage, among programs having different priority information, programs having higher different priorities are ranked higher. Program A includes priority 1, program B includes priority 1 and priority 2, and program C includes priority 1 and priority 3, so programs A to C have different priority information. It can be said that it has. As a program having a higher priority, program B has priority 2 because it has priority 2, and program C has priority 3, so it is ranked second. Since A does not have anything other than priority 1, it is ranked third. Therefore, the final recommended order considering the third stage is program B> program C> program A> program D.

  As a result of the determination, the process proceeds from step S12 to step S13, the program B having the first recommendation rank is selected, and then the process proceeds to step S14, where the program C having the second recommendation rank is set by the user in advance. Record on the recorded recording medium.

  In the above example, there is one program with the recommended ranking of 1st and 2nd, but as another example, when there are a plurality of programs with the recommended ranking of 1st, for example, FIG. As shown in the screen 80, when the list is displayed and the cursor 81 is movable and the enter key is pressed, the program selected by the cursor 81 may be selected. Then, as shown in the screen 90 of FIG. 12, the selected program can be selected by shading display 92 or the like, and the program to be recorded can be selected from the remaining programs with the cursor 91 and the enter key. do it. There is also an option not to record.

  As another example, when there is one program with the first recommended rank and there are a plurality of programs with the second recommended rank, for example, as shown in a screen 100 in FIG. When the list of the 2nd program is displayed and the cursor 101 is movable and the enter key is pressed, the program selected by the cursor 101 is recorded, and the program with the 1st recommended ranking is automatically selected. You just have to do it. There is also an option not to record.

  If no program is extracted as a result of the program search, a message indicating that there is no corresponding program may be displayed.

  As described above, according to the present invention, by determining the recommendation order according to the priority, the program search reflecting the user's preference can be performed, and the user's satisfaction can be improved.

  The present invention can be used for a television receiver, a television receiver including an HDD and an optical disk device.
