Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a diagram for explaining the outline of a two-dimensional code creation / display system 1 that embodies the method of the present invention.
The two-dimensional code creation / display system 1 receives a broadcast data broadcast program, and creates and displays a two-dimensional code.
The two-dimensional code creation / display system 1 includes a broadcast station 500, a digital broadcast receiver 100, a television 200, and a mobile terminal device 300 (= mobile phone).

The broadcasting station 500 includes a data broadcasting server device 701.
The mobile terminal device 300 is connected to the data broadcasting server device 701 via the Internet 903 by bidirectional communication.

A digital broadcast receiver 100 used by a viewer is connected to a BS / CS 110 ° antenna 901, a UHF antenna 902, a control terminal 600 (= remote control), and a television 200 (TV monitor).
The digital broadcast receiver 100 includes a memory area. The memory area of the digital broadcast receiver 100 stores a BML browser that reproduces and displays BML content on the television 200.
The control terminal 600 receives information input by the viewer.

The mobile phone 300 captures a two-dimensional code image displayed on the television 200, decodes information included in the captured two-dimensional code image, and accesses the data broadcast server device 701.

The digital broadcast signal of the data broadcast program transmitted from the broadcast station 500 is received by the BS / CS 110 ° antenna 901 and the UHF antenna 902 via the BS / CS 110 ° satellite 905 and the transmitting station / relay station 906.

The digital broadcast receiver 100 converts the digital broadcast signal received by the BS / CS 110 ° antenna 901 and the UHF antenna 902 into a main broadcast screen and a data broadcast screen and displays them on the television 200.

The data broadcast program includes BML content composed of a plurality of BML scripts. (Details will be described later)
The digital broadcast receiver 100 receives a data broadcast program. A central processing unit (hereinafter referred to as CPU) built in the digital broadcast receiver 100 interprets the received BML script, thereby realizing each unit of the system described later.

FIG. 2 is a diagram for explaining a rough processing flow of the two-dimensional code creation / display system 1 according to the present invention.
The broadcast station 500 includes 16 image patterns (2 cell × 2 cell image patterns) and scripts executed as various means in the BML content and transmits a broadcast signal. (Fig. 2 (1))
When the digital broadcast receiver 100 selects a data broadcast, the BML content is cached (stored) in the working memory of the digital broadcast receiver ((2)).

The CPU reads the corresponding script from the BML content cached in the working memory and executes the following processing.

That is, the remote control acceptance script accepts input of information to be embedded in the two-dimensional code ((3)).
The two-dimensional code generation script creates two-dimensional code data ((4)).
The conversion script converts the two-dimensional code data into an image object using a 2 cell × 2 cell image pattern ((5)). That is, by using an image pattern of 2 cells × 2 cells, a two-dimensional code of 41 cells × 41 cells can be expressed by 21 × 21 image objects. By the way, in the QR code (registered trademark) (version number “6”) of 41 cells, the number of characters that can be embedded is 134 characters in binary notation.

The BML browser displays the image pattern (that is, the two-dimensional code image) of the image object on the television 200 ((6)).

The viewer captures the two-dimensional code image displayed on the television 200 with the mobile phone 300, decodes the information included in the captured two-dimensional code image, accesses the data broadcasting server device 701, and transmits the data. Receive interactive services for broadcast programs.

FIG. 3 is a basic configuration diagram of a digital broadcast receiver 100 used in digital broadcasting.
The digital broadcast receiver 100 selects a channel with the tuner unit 102 and the demodulation unit 103, and selects one transport (= TS) stream. The descrambling 104 releases the scramble of the broadcast signal. By selecting a desired packet in the TS decode 105, a specific program on a specific channel is selected. The main line video / audio signal is converted into a signal accepted by the TV monitor 200 by the MPEG decoder 113 and presented.

  The working memory 106 is a storage area in which BML contents of a selected channel are cached (temporarily stored). When the channel is changed or when a message is received from the broadcasting station notifying that the content of the BML content has been changed, the new BML content is fetched and held here.

  The input / output port 110 receives a signal from the remote controller 600 operated by the viewer. The modem interface 109 is connected to a public line. The non-volatile memory 108 has an area that can be used for each broadcaster. The data recorded in the non-volatile memory is retained as it is even when the receiver 100 is turned off. The volatile memory 115 is a temporary storage area in which data can be stored only while the same channel is selected. When moving to another station, the data on the volatile memory 115 is erased. The IC card interface 111 reads and writes data of the IC card 112 in which viewer identification information, personal information, and the like are recorded.

  The CPU 107 receives a command or the like by a remote control operation from the input / output port 110, controls the receiver 100, and reads and interprets the BML content cached in the work memory 106 and selects data broadcast screen data when data broadcast is selected. And is written in the video memory of the graphic controller 114. Thus, the data broadcast screen is displayed on the TV monitor 200.

The illustrated BML document is "<BML><HEAD><SCRIPT> ...... (Describe scripts that implement various means) ...... </ SCRIPT></HEAD><BODY> ...... (Describe screen structure) ) ... </ BODY></BML>".

FIG. 5 is a conceptual configuration diagram of the BML script.

Functions realized by executing the BML script on the receiver 100 include a remote control receiving unit 110, a URL generation unit 120, a two-dimensional code generation unit 130, an image pattern selection unit 140, and an image object creation unit. Reference numeral 150 denotes a data broadcast screen creation display means 160.

Remote control receiving means 110 receives a character string input from remote control 600 by the viewer.
The URL creating unit 120 creates a URL including the character string received by the remote control receiving unit 110.
The two-dimensional code generation unit 130 encodes the URL created by the URL creation unit 120 into two-dimensional code data.

The image pattern selection means 140 extracts predetermined array data and its array position information from the array of 2D code data created by the 2D code generation means 130, and creates pattern identification information.
The image object creation unit 150 creates an image object described by a BML tag using the position information corresponding to the array position information extracted by the image pattern selection unit 140 and the pattern identification information created by the image pattern selection unit 140. .

Note that the image object created by the image object creation unit 150 causes the BML browser to display image pattern data corresponding to the pattern identification information.
Alternatively, when the image object having the same color as the background color (= empty image object) is displayed by the BML browser and the image object creating unit 150 rewrites the empty image object with the pattern identification information, the rewrite is performed. The image object may be displayed after being updated to the corresponding image pattern data by the BML browser.
