  FIG. 6 is a diagram for explaining processing of the video viewing system shown in FIG. Hereinafter, an operation of performing personal authentication by bringing the portable information terminal 1 close to the server device 2 and allowing the user 3 to view the viewing information 251 will be described.

  First, the portable information terminal 1 and the server device 2 are activated (steps 1000 and 2000). The portable information terminal 1 searches the server device 2 based on the communication start procedure defined by the communication protocol of the communication unit 100 (step 1001). The server device 2 receives this search using the communication unit 200, and measures the distance between the portable information terminal 1 and the server device 2 (step 2001). This distance is, for example, a physical distance if wireless, and a router hop count according to the IP protocol if wired. That is, it is only necessary to measure the logical distance as a numerical value. If the distance measured in step 2001 is larger than a predetermined value set in advance by the server device 2, the process returns to step 2001 and repeats the distance measurement (step 2002). If it is smaller than the predetermined value, it is determined that the portable information terminal 1 is close to the server device 2, and the process proceeds to step 2003. When determining that the server device 2 is close, the server device 2 transmits a request to the portable information terminal 1 to transmit the authentication information 103 to the server device 2 using the communication unit (step 2003). When the portable information terminal 1 receives the transmission request for the authentication information 103 via the communication unit 100 (step 1002), the portable information terminal 1 proceeds to step 1004. Otherwise, the process proceeds to step 1008.

  In step 1002, when a transmission request for authentication information 103 is received, the authentication information 103 is acquired from the authentication information table 102 held in the storage device of the portable information terminal 1 (step 1004). At this time, the user 3 uses the user interface of the portable information terminal 1 to input the PIN information 301 described with reference to FIG. Next, the acquired authentication information 103 is transmitted to the server device 2 using the communication unit 100 (step 1005). The server device 2 receives the authentication information 103 transmitted by the communication unit 100 of the portable information terminal 1 via the communication unit 200 (step 2004). Then, the identification information 320 included in the authentication information 103 is acquired. When acquiring the identification information 320, the PIN information 321 is collated with reference to the PIN information 301 input by the portable information terminal 1, and the identification information 320 is validated if they match (step 2005). Next, an identification ID 322, personal information 323, and access right 324 are acquired from the identification information 320 (step 2006). Next, the presence / absence of an access right to the viewing information 251 stored in the viewing information holding unit 250 of the server device 2 is checked to determine whether the access right 324 can be obtained (step 2007). If authentication fails, the process is repeated from step 2001. If acquisition is possible, the viewing information 251 is acquired from the viewing information holding unit 250 (step 2008).

  Next, the attribute information 330 is acquired from the authentication information 103. When acquiring the attribute information 330, the PIN information 331 is collated with reference to the PIN information 301 input in the portable information terminal 1, and the identification information 330 is validated if they match (step 2009). Then, the PIN information 331, the attribute ID 332, the image quality ID 333, the sound quality ID 334, the size ID 335, and the time ID 336 are acquired from the attribute information 330 and the viewing information is processed (step 2100). The viewing information processing process (step 2010) will be described later. Next, the viewing information 251 processed in the processing for viewing information (step 2100) is transmitted to the portable information terminal 1 using the communication unit 200 of the server device 2 (step 2011), and the process returns to step 2001 to repeat the distance measurement. .

  The portable information terminal 1 receives the viewing information 251 transmitted by the server device 2 in step 2010 (step 1006), and holds the viewing information 251 in the storage device of the portable information terminal 1 (step 1007). At this time, if the user 3 does not instruct to view the viewing information 251 using the user interface, the process is repeated from step 1001 (step 1008). When the user 3 instructs to view the viewing information 251 using the user interface, the viewing information 251 is acquired from the viewing information holding unit 105 (step 1009), and the video / audio playback device 108 and the meta of the mobile information terminal 1 are acquired. The video / audio and metadata included in the viewing information 251 are reproduced using the data reproducing device 109 (step 1010).

  As described above, personal authentication is performed by bringing the portable information terminal 1 close to the server device 2, and the viewing information 251 can be viewed by the user 3.

  FIG. 7 is a diagram for explaining processing for processing the viewing information 251 in accordance with the attributes of the user 3 stored in the portable information terminal 1.

  First, the user 3 inputs the PIN information 331 described with reference to FIG. 4 using the user interface of the portable information terminal 1 and acquires the attribute information 330. If the PIN information 331 does not match (step 2101), the processing 2100 of the viewing information 251 ends (step 2117). If they match, the attribute information 330 of the authentication information 103 is acquired (step 2102). Here, the attribute ID 332, the image quality ID 333, the sound quality ID 334, the size ID 335, and the time ID 336 are acquired. If any of these does not exist, it may not be acquired.

  Next, the processing information table 259 held by the viewing information processing unit 257 is sequentially searched to determine whether there is processing information (step 2103). If there is no processing information, the processing 2100 is terminated (step 2117). If there is processing information, processing information 340 to 341 is acquired (step 2104). Here, with reference to the attribute ID 350 of the acquired processing information, it is determined whether or not it matches the attribute ID 332 of the attribute information 330 (step 2105). If they do not match, the process proceeds to step 2103 to obtain the next processing information 340 to 341. If they match, the process ID 351 of the process information 340 to 341 is referred to, and it is determined whether or not it matches the image quality ID 333 of the attribute information 330 (step 2106). If they match, the image quality information is acquired from the processing instruction information 352 (step 2107).

  Next, with reference to the processing ID 351 of the processing information 340 to 341, it is determined whether or not it matches the sound quality ID 334 of the attribute information 330 (step 2108). If they match, the sound quality information is acquired from the processing instruction information 352 (step 2109). Next, with reference to the process ID 351 of the process information 340 to 341, it is determined whether or not it matches the size ID 335 of the attribute information 330 (step 2101). If they match, size information is acquired from the processing instruction information 352 (step 2111). Next, with reference to the process ID 351 of the process information 340 to 341, it is determined whether or not it matches the time ID 336 of the attribute information 330 (step 21012). If they match, time information is acquired from the processing instruction information 352 (step 2111).

  All the processing instruction information 352 specified by the attribute information 330 can be acquired through the steps so far. Next, the data amount per unit time is calculated from the size information of the processing instruction information 352, the time information, and the total data amount of the viewing information 251 (step 2114). Next, from the data amount per unit time, the image quality information, and the sound quality information, it is calculated how much the viewing information 251 can be compressed and the target processing can be realized, and the compression rate is calculated as a numerical value (step 2115). . Next, based on the numerical value of the compression rate, the viewing information 251 is temporarily expanded and then compressed again to change the compression rate of the viewing information 251 (step 2116), and the processing 2100 of the viewing information 251 is ended. (Step 2117). Thereby, the operation | movement which processes the viewing-and-listening information 251 according to the attribute of the user 3 of the portable information terminal 1 is realizable.

  As described above, according to the present embodiment, personal authentication is performed by bringing the portable information terminal 1 close to the server device 2, and further, processing according to the user attribute is added to the viewing information stored in the server device. You can create a preview and send the created preview to your mobile device.
