A description will be given for each step number.

  The processing up to step S105 is the same as in the related information display timing example 1-1.

The priority determination unit 18 refers to the viewing history stored in the storage unit 14 and gives priority to the related information. For example, as shown in 84A, 84B, 84C, and 84D in FIG. 17, the priority is given to a program that has been viewed most recently. Also, the priority is higher for the scene / time that was viewed more recently in the same program. It is not necessary to give priority to programs that are not viewed by the user. (S116)
Next, the user finishes viewing the program and performs an operation of turning off the screen display of the display unit 13. (S106)
The display control unit 12 refers to the priority given to the related information, and displays the related information with the highest priority on the display unit 13 in order from the left side, for example, as indicated by 84E in FIG. (S208)

The transmission unit 16 transmits the viewing history of the program viewed by the user to the reception unit 25 of the information processing apparatus 20d.

  Next, the flow of processing of the display system 1d 'in this example will be described with reference to FIGS.

  FIG. 17 is a diagram showing a flow of related information display in this example.

  FIG. 20 is a sequence diagram showing the process until the user starts viewing the program and the related information is displayed on the display screen in the processing shown in FIG. 17, and until the related information is displayed on the screen, FIG. A description will be given for each step number.

  The processing up to step S112 is the same as in the related information display timing example 1-3.

The control unit 21 refers to the viewing history stored in the storage unit 23, and whether or not each related information stored in the storage unit 23 is related information related to a program at least partially viewed by the user. Determine. If the related information is related information that the user has viewed at least part of, the priority determination unit 28 gives priority to the related information. For example, as shown in 84A, 84B, 84C, and 84D in FIG. 17, the priority is given to a program that has been viewed most recently. There is no need to give priority to programs that are not viewed by the user. (S117)
In the predetermined related information, the priority is present for each individual user or terminal, and the priority value is naturally different. The related information output unit 24 transmits to the related information acquisition unit 15 of the display device 10a the related information to which priority is given, which is related to a program that the user has watched at least part of. (S404)
The control unit 11 of the display device 10 a stores the related information received by the related information acquisition unit 15 in the storage unit 14. (S405)
Since the viewing history is transmitted to the information processing device 20d every predetermined time or every time the channel is changed, the display device 10a receives related information as feedback each time. In other words, steps S111 to S405 are repeated until the user turns off the screen display. In addition, regarding the related information once transmitted to the display device 10a by the information processing apparatus 20d, when only the priority is updated, it is sufficient to transmit only the priority given to the related information.

Next, the user finishes viewing the program and performs an operation of turning off the screen display of the display unit 13. (S106)
The display control unit 12 refers to the priority given to the related information, and displays the related information with the highest priority on the display unit 13 in order from the left side, for example, as indicated by 84E in FIG. (S208)
When the related information is not referred to during the display of the related information, the display control unit 12 turns off the screen of the display unit 13 as indicated by 84G in FIG. In addition, when the user performs an operation to turn off the screen display of the display unit 13 again, the display of the related information may be immediately terminated. When the related information is referred to during the display of the related information, the display control unit 12 cancels the operation of turning off the screen of the display unit 13 after a predetermined time has elapsed.

  Even in the configuration described above, the same effects as those of the priority assignment example 1-1 for the related information are obtained.

<Additional remarks relating to examples 1-1 and 1-2 of assigning priorities to related information>
In the priority assignment examples 1-1 and 1-2 for the related information, the priority is given according to the viewing history of the user. For example, the viewing time, the audience rating of the program, the use history of the TV, the net shopping history The user's schedule, outing history, cooking history, sleep history, exercise history, travel history, or other history of the user's action (user's behavior history) may also be a factor for determining the priority. Further, the display device 10a or the display device 10d may have a function of connecting to the Internet, and the priority may be determined from the history of applications such as the user's net shopping. Alternatively, the display device 10a or the display device 10d may include a camera and a line-of-sight detection unit, and the priority determination unit 18 may refer to the detection result of the line-of-sight detection unit to determine the priority of the user's line of sight.

  Also, the loudness of the viewer's voice may be recognized with a microphone and reflected in the priority. Moreover, priority may be added according to the audience rating or the like. In addition, when only a part of the viewing program is viewed, the priority order of the portions that are not viewed may be displayed with a lower priority.

  Moreover, it is good also as a structure which changes the magnitude | size of the display of each relevant information, or the color intensity according to a priority.
