Description

  The present invention relates to a portable terminal and a program selection assistance system capable of receiving and displaying a broadcast program, multimedia content distributed from the Internet, and the like.

  With the spread of terrestrial digital broadcasting, services to provide broadcast programs for mobile terminals are being expanded. On the other hand, the number of programs equivalent to broadcast programs and broadcast programs such as terrestrial broadcasts, BS broadcasts, CS broadcasts, cable TV, Internet broadcasts, streaming broadcasts, etc. has been increasing. Finding programs has become a very complex task. Thus, development of an apparatus capable of preferentially displaying a program that matches the user's preference by learning the user's preference is being promoted.

  Among stationary devices that record analog terrestrial television broadcasts, there is a broadcast terminal device having a function of learning the user's preference for broadcast programs (see, for example, Patent Document 1). By continuing to use the broadcast terminal device for a long time, preference information such as a user's usage history is gradually accumulated in the broadcast terminal device, so that a program that matches the user's preference can be automatically recorded. However, since the stored information is used only within the broadcast terminal device, when there are a plurality of broadcast terminal devices that the user wants to use, the stored information cannot be reflected on other broadcast terminal devices. In addition, when the same device is shared by a plurality of users, it is cumbersome to separately classify and store the preference information of each user. Programs that do not fit may be recorded.

  Various programs of terrestrial digital broadcasting include various program additional information in addition to video and audio. In order to reproduce or display the program additional information, it is necessary to transfer or activate a necessary processing program. However, the transfer or activation of the processing program is generally executed after the program additional information is selected. For this reason, it takes time from the selection of the program additional information to the reproduction or display.

The channel selection unit 122 selects a specific broadcast program from a plurality of broadcast programs based on the information recorded in the recording device 13. The collecting means 123 collects the viewing state of the user obtained from the sensor means 18 and the program additional information of the broadcast program obtained via the broadcast wave transmission path 10A or the communication path 10B.

  The analysis unit 124 analyzes the collection result of the viewing state of the user by the collection unit 123 using the program additional information added to the broadcast program. The creating unit 125 creates a preference information table (see FIG. 3) for evaluating the user's preference according to the viewing state. The recording unit 126 records the information of the preference information table created by the creating unit 125 in the recording device 13.

  FIG. 3 shows an example of the preference information table. In the preference information table, for example, at least ID information for specifying a broadcast program, user preference information, priority of a broadcast program, and related information of a broadcast program are stored. As the preference information, for example, program additional information added to a broadcast program, time information representing viewing time, position information representing viewing position, motion information representing movement during viewing, and the like are stored. The program additional information may be transmitted simultaneously with the broadcast program or may be transmitted independently of the broadcast program together with electronic program guide (EPG) data or the like, but may be transmitted in any format.

  For example, when a user listens to a specific broadcast program, the ID information is “05090111030”, the program additional information is “CH: 1004, TL: Good morning news, CA: news, AU: −yama △ man, AU: −river ☆ "Beauty", time information "200508151430, 200508151600", position information "N035904, E1394529", motion information "SW-016.66", priority "10", related information "http://1001ch.jp" / "Is stored in the preference information table shown in FIG.

The sensor means 18 includes a global positioning system (GPS) and an electronic compass, and detects the position, movement, etc. of the user.

-How to watch broadcast programs using mobile devices-
An example of a trial listening of a broadcast program using the mobile terminal 1 shown in FIG. 1 will be described using the flowcharts shown in FIGS. 4 and 5.

  In step S21 of FIG. 4, when the operation unit 15 is operated by the user, the determination unit 121 determines the broadcast reception mode. If the broadcast reception mode is determined to be “automatic mode”, the process proceeds to step S40. Details of step S40 will be described later. If it is determined that the broadcast reception mode is a “learning mode” for learning user preference information, the process proceeds to step S22.

  In step S22, when the user selects television reception via the operation unit 15, and in step S23, a specific channel is selected via the operation unit 15, the broadcast wave of the selected channel is transmitted to the broadcast wave transmission path. It is input via 10A. Then, processing such as demodulation is performed by the communication unit 11, and reception data in a format handled by the mobile terminal 1 is generated. The generated reception data is sent to the multimedia processing means 14 via the control means 12. In the multimedia processing unit 14, the data is converted into a data format corresponding to the output device, and the audio data is sent to the audio output unit 16 and the video data is sent to the display unit 17. Thereby, as shown in step S24, program viewing is started. When the program is being viewed in step S24, the multimedia processing means 14 performs conversion processing of audio data and video data used for the broadcast program with high priority recorded in the preference information table of FIG. Prepare various programs to be used. Thereby, when a different broadcast program is selected via the operation means 15, it becomes possible to shorten the start time of the program required for reproduction from the selection of the broadcast program.

  In step S25, the collection means 123 of FIG. 2 executes viewing mode information collection processing for preference information learning. As the viewing form information collection processing, for example, as shown in FIG. 3, the collection unit 123 collects an ID for identifying a viewing program such as “050901130”, and a viewing start time “200508151430”. Subsequently, the collection unit 123 controls the GPS in the sensor unit 18 to collect the position information “N0353904, E134529”. When the GPS does not function, the collection unit 123 may collect the position information from the base station information of the mobile phone obtained through the communication path 10B. Subsequently, the GPS and accelerometer in the sensor means 18 are controlled by the collecting means 123 to collect motion information “SW-016.66” shown in the form of vector data consisting of the moving direction and moving speed.

  In step S26, the program additional information “CH: 1004, TL: Good morning news, CA: News, AU: −Yama △ male, AU: −Bi ☆ Bi” acquired by the collection unit 123 via the communication unit 11; Time information “200508151430, 200508151600” and related information “http://1001ch.jp (here, Internet access information)” are collected. Then, the analysis unit 124 performs analysis for associating the program additional information, time information, and related information collected via the communication unit 11 with the viewing mode information acquired in step S25.

  In step S27, the determination unit 121 determines whether or not the user ends viewing. If the viewing is not terminated, the process proceeds to step S24. On the other hand, when an instruction to end viewing is input from the operation unit 15, the creation unit 125 creates a preference information table based on information that has been updated so far, based on the analysis result. In step S28, the information in the created preference information table is recorded in the recording device 13 as one item in the preference information table shown in FIG. At this time, priority information calculated using an algorithm based on viewing frequency or the like is also created by the creating unit 125 and recorded in the recording device 13 by the recording unit 126. The priority can be determined, for example, by evaluating the appearance frequency of the keyword included in the program additional information by scoring the relationship of the usage frequency of the user.

  In step S29, the control means 12 controls a reception end process for ending the functional blocks necessary for receiving the TV program in the portable terminal 1 of FIG. 1 according to a predetermined procedure, and the TV program reception ends.

  The automatic channel selection process shown in step S40 will be described using the flowchart shown in FIG.

  In step S41, program additional information is input to the communication means 11 via the broadcast wave transmission path 10A or the communication path 10B. For example, the program additional information table shown in FIG. 6 is input based on the information input from the operation means 15 by the program additional information in the same time zone of the channel whose service area is the place operated by the user. In the program additional information table shown in FIG. 6, the channel number “1001, 1004,...”, The title TL “Grand Sumo, Afternoon Wide Show,. , Δ mountain, Δ field, and category CA “sports, information variety,...” Are input. The program additional information is recorded in the recording device 13 via the control means 12.

  In step S <b> 42, based on the information input via the operation unit 15, the determination unit 121 determines the automatic channel selection method (channel selection mode). In the example shown in FIG. 5, a method based on “program additional information” and a method based on “position / motion information” can be selected. If it is determined as “program additional information”, the process proceeds to step S48, and channel selection is automatically performed by comparing the program additional information with the priority recorded in the preference information table shown in FIG. If it is determined as “position / motion information”, the process proceeds to step S43.

  In step S43, the collection unit 123 of the control unit 12 causes the viewing form information, for example, viewing time “200505051510”, viewing position “N0353904, E1394529” and motion information “SW-001.10” as shown in FIG. The viewing time “200505051510”, the viewing position “N0353209, E1394203”, and the motion information “NW-016.66” as illustrated in FIG. 8 are collected via the GPS of the sensor unit 18 or the like. The collection result is stored in the recording device 13. When the GPS does not function, the collecting unit 123 may collect the position information and the movement information from the base station information of the mobile phone obtained via the communication path 10 </ b> B and record it in the recording device 13.

  In step S44, the analysis means 124 of the control means 12 compares the viewing mode information as shown in FIGS. 7 and 8 with the position information and motion information of the preference information table shown in FIG. analyse. If the viewing mode information is the example shown in FIG. 7, candidates that include information that matches the position information “N0353904, E1394529” in FIG. 7 or information within the neighborhood threshold from the preference information table in FIG. 3 are candidates. . Here, the ID “050901130” and the ID “05090222030” in FIG. 3 are candidates. Subsequently, the analysis unit 124 refers to the motion information shown in FIG. 7 and the motion information in the preference information table shown in FIG. 3 to select candidates whose vector amounts match or approximate. When FIG. 7 and FIG. 3 are compared, the motion information of the ID “050902020” matches the vector amount of the motion information of FIG. 7, so the ID “05090222030” is the final candidate. The analysis result of the final candidate is recorded in the recording device 13. When there are a plurality of candidates, the one with the highest determination coefficient at the time of candidate selection is selected. Or you may judge using other preference information, such as time information.

  When the collected viewing mode information is the example shown in FIG. 8, the analysis unit 124 selects the ID “05090336080” and the ID “05090447090” in the preference information table of FIG. 3 as candidates. Subsequently, the analysis unit 124 analyzes and selects an ID “05090447090” that is close as a vector quantity from the motion information as a final candidate. The analysis result of the final candidate is recorded in the recording device 13.

  In step S45, the channel selection means 122 of the control means 12 reads the final candidate ID information recorded in the recording device 13, and the program additional information associated with the ID information and the program additional information table of FIG. By comparing the contents, the channel with the highest degree of matching of the constituent elements is selected. For example, when the ID “0509022030” in FIG. 3 is selected as the final candidate, the channel selection means 122 selects the program additional information “CH: 1001, TL: baseball broadcast, CA: sports” attached to the ID “05090222030”. , AU: □ mountain-, AU: Δ river-"and the program additional information table of FIG. 6 are compared to select channel 1001 and output it to display means 17 and audio output means 16.

  In step S46, the determination unit 121 of the control unit 12 determines whether or not the channel selection is appropriate. If it is determined that the channel selection is not appropriate, the process returns to step S43. If it is input that the channel selection is valid, the process proceeds to step S47 and the viewing is continued. The determination of the validity of the automatic channel selection shown in step S46 does not have to be explicitly performed by the user via the operation unit 15. If there is no refusal operation from the operation unit 15 for a certain time, the determination unit 121 is determined. However, it may be determined that the channel selection is appropriate.

  According to the mobile terminal 1 according to the embodiment of the present invention, the recording device stores the preference information table based on the viewing state of the user such as program additional information, viewing time, viewing position, and motion information when viewing a broadcast program. The program to be viewed is automatically selected based on the information in the preference information table. Therefore, it is possible to easily select a broadcast program that suits the user's preference from various broadcast programs according to the viewing state of the user. For example, when a user views a television program A while traveling in a car or the like in the evening, a preference table is created based on the viewing state. The television program A can be preferentially displayed simply by selecting “TV viewing” via the operation means 15 in step 1.

  Further, by recording a preference learning table as illustrated in FIG. 3 on a mobile terminal that is used more frequently than a conventional stationary broadcasting terminal device, it can be used even in a stationary broadcasting terminal. You can tune in a broadcast program that suits the taste of the user. Moreover, since the information of the preference information table recorded in the recording device 13 of the portable terminal 1 can be transmitted to and received from a plurality of electronic devices via the communication unit 11, the type of electronic device, the owner of the electronic device, In addition, it is possible to select a broadcast program that matches the user's preference with high accuracy without depending on the location of the electronic device.

  By the way, when a user views a broadcast program, there are cases in which video is important and audio is important, and there are various modes of viewing. Therefore, as shown in the preference table shown in FIG. 9, as the user preference information, output restriction information (main panel, sub-panel, And a window position or a display size in the high-resolution main panel). Then, the control means 12 reads out the output restriction information recorded in the preference information table of FIG. 8, and controls the processing for displaying the specific broadcast program on the audio output means 16 and the display means 17 based on the output restriction information. Thus, the broadcast program can be viewed in an output format that meets the user's preference without any special setting.
