  Processing of the television receiver 10 configured as described above will be described with reference to a flowchart shown in FIG.

  The television receiver 10 analyzes content data such as broadcast waves received by the tuner 16 by the analysis device 18. This analysis process includes a process for recognizing character data included in the received content data, a process for recognizing image data such as a QR code, and the like. At the same time, a process for searching for a portable terminal (a portable terminal capable of performing wireless communication with the short-range wireless unit 17) compatible with short-range wireless communication is started (step S101). The television receiver 10 writes content data in the buffer 15 at regular intervals. When the CPU 12 confirms that new content data has been stored in the buffer 15, the analysis device 18 analyzes the contents of the buffer 15.

  In step S101, the content data analysis processing analyzes, for example, a QR code (see FIG. 5) displayed on the display device 13 of the television receiver 10. To analyze the QR code, first, color difference information is extracted from the content data. When it is determined that the portion having large color difference information, that is, the edge is concentrated in a square area, the determined square area is cut out and extracted. If a three-point double square 200 (see FIG. 5), which is a feature of the QR code, is recognized in the extracted square area, it is determined that it is a QR code. In this case, the analysis device 18 receives a command from the CPU 12 and extracts feature points of the two-dimensional information from the content data stored in the buffer 14 (for example, a character string called QR code having a square regular region) Is recognized by the OSD). When the feature point can be extracted, the information included in the two-dimensional information is analyzed and the analysis result is stored in the storage device 15.

  In step S101, the content data analysis processing analyzes character data (see FIGS. 8 to 10) displayed on the display device 13 of the television receiver 10, for example. To analyze the character data, first, color difference information is extracted from the content data. Text data is extracted using a OSD signal for a portion having large color difference information. In this case, the analysis device 18 receives a command from the CPU 12 and extracts feature points of the two-dimensional information from the content data stored in the buffer 14 (for example, character data displayed in the lower half of the display device 13 is subjected to OCR. (Text data is extracted by pattern matching software such as (Optical Character Reader)).

  The extracted text data such as URLs and characters is stored in the storage device 15. For example, as illustrated in FIGS. 8 to 10, when a plurality of text data is extracted, the plurality of text data is stored in the storage device 15.

  Next, when the CPU 12 of the television receiver 10 searches for a portable terminal that supports short-range wireless communication nearby (YES in step S102), the searched portable terminal, for example, the portable terminal 20 is in a standby state. It is determined whether or not (communication is possible) (step S103). For this determination, the CPU 12 of the television receiver 10 can access the portable terminal 20 via the short-range wireless unit 17 of the television receiver 10 and can communicate depending on whether there is a response from the portable terminal 20. Is determined. In step S103, if the CPU 12 of the television receiver 10 determines that the searched mobile terminal 20 is in the standby state (YES in step S103), it is stored (stored) in the storage device 15 of the television receiver 10. ) Is transferred (transmitted) to the portable terminal 20 via the short-range wireless unit 17 (step S104). When the transfer (transmission) of text data or the like from the television receiver 10 to the portable terminal 20 is completed, a completion display 10-2 is displayed on the display device 13 (speaker 10), for example, as shown in FIGS. The sound may be output from -5). In addition, a reception completion signal is transmitted from the portable terminal 20 to the television receiver 10. Receiving this reception completion signal, the television receiver 10 deletes the corresponding text data stored in the storage device 15. The timing of deleting the text data is when the remaining capacity of the storage device 15 reaches a predetermined capacity when a reception completion signal is received from the mobile terminal 20. When erasing is performed when the remaining capacity of the storage device 15 reaches a predetermined capacity, the old data is erased, for example.

  On the other hand, when the CPU 12 of the television receiver 10 determines in step S103 that the searched portable terminal 20 is not in the standby state (NO in step S103), the display device 13 of the television receiver 10 stores the storage device. The fact that there is accumulated information such as text data stored in 15 is displayed and the television receiver 10 enters a standby state (step S105). The display indicating that there is accumulated information such as text data stored in the storage device 15 in the display device 13 is displayed as a “transferable list” as shown in FIG. 12, for example. As described above, when the character data displayed in FIGS. 8 to 10 is extracted and stored as text data, three transferable text data are stored in the storage device 15. Selectable display in the "Available list". In addition to the three pieces of transferable information, all transfer selection items may be displayed. Further, as shown in FIG. 13, a display such as “Touch with mobile phone. Data remaining 3 (pieces)” is displayed on the display device 13 and prompts the user to transfer information via the short-range wireless unit 17. Is displayed (or see FIG. 6). Since short-range wireless communication is used, wireless communication is performed at a short distance by touching the cellular phone or touching the cellular phone.

  Further, when transferable text data is stored in the storage device 15, the LED (lighting unit) 10-4 may be turned on. Furthermore, when transferable text data is stored in the storage device 15, a predetermined voice may be output from the speaker (voice output unit) 10-5. Thereby, it is possible to prompt the user to prepare the mobile terminal so that it can be received.

  Next, it is determined whether or not the searched mobile terminal, for example, the mobile terminal 20 is in a standby state (step S106). In this determination, as in step S103, the CPU 12 of the television receiver 10 accesses the portable terminal 20 via the short-range wireless unit 17 of the television receiver 10, and receives a response from the portable terminal 20. Whether or not communication is possible is determined based on whether or not the communication is possible. In step S103, if the CPU 12 of the television receiver 10 determines that the searched mobile terminal 20 is in the standby state (YES in step S106), it is stored (stored) in the storage device 15 of the television receiver 10. ) Is transferred (transmitted) to the portable terminal 20 via the short-range wireless unit 17 (step S104).

  On the other hand, when the CPU 12 of the television receiver 10 determines in step S106 that the searched mobile terminal 20 is not in the standby state (NO in step S106), the television receiver 10 is still in the standby state. The CPU 12 of the television receiver 10 determines whether or not the standby state of the television receiver 10 continues for 3 minutes, for example (step S107). In step 107, when the CPU 12 of the television receiver 10 determines that the standby state of the television receiver 10 continues for, for example, 3 minutes (YES in step S107), the standby state of the television receiver 10 is changed. Release (step S108).

  According to the above-described embodiment, it is possible to apply analysis processing to all received content data, extract text data, and transfer it to a mobile terminal. Further, in the case of a device such as a television receiver in which display information is constantly updated and the display information cannot be operated on the device side, the display information can be stably sent to the receiving device. .

  In the above-described embodiment, the analysis of the content data is started with the start of the reception of the content data. However, when the television receiver 10 receives the analysis start signal from the mobile terminal 20, the reception is received. Analysis of content data may be started. In addition, instead of the analysis start signal from the mobile terminal 20, the analysis of the received content data is started when an analysis start signal is received by pressing a predetermined key of a remote controller capable of operating the television receiver 10. You may do it. In this case, when the analysis of the content data is completed (for example, when one QR code is extracted), the analysis process is automatically canceled (stopped).
