  On the other hand, when the average value avn of the reception level is equal to or less than the threshold th, the download content reproduction process is performed because there is a possibility that the advertisement content video and audio may be stopped or skipped due to the deterioration of the reception state. (Step Sa8).

  In the download file playback process, the presence / absence of quality-complementary video / audio and the presence / absence of alternative-complementary video / audio are determined for the advertisement video / audio. The advertisement video / audio in the stream video / audio is reproduced.

  FIG. 9 is a flowchart for explaining the operation of the download content reproduction process according to the present embodiment. First, it is determined whether or not there is a download file (step Sb1). If there is no download file, the streaming playback unit 210 continues to play the advertisement content video and audio (step Sb8). On the other hand, if there is a download file, the quality-complementary video / audio is searched (step Sb2).

  Quality supplemental video / audio presence / absence judgment is based on “Advertiser”, “Advertising title”, “Advertising time” of quality supplemental video / audio metadata and “Advertiser”, “Advertising title” This is done by comparing each item with “Advertising time”. The logical product of the results after comparison of each item is calculated, and the one that is true is selected as the quality-complementary video / audio of the advertising video / audio in the stream video / audio. Details of the quality-complementary video / audio search process will be described later.

  Next, based on the search result of the quality-complementary video / audio, it is determined whether or not there is a corresponding quality-complementary video / audio (step Sb3). (Step Sb4). On the other hand, if there is no relevant quality-complementary video / audio, an alternative complementary video / audio is searched (step Sb5).

  As shown in FIG. 9, the determination of the presence / absence of alternative complementary video / audio is processed step by step as primary selection, secondary selection, and tertiary selection. The primary selection is “Advertiser”, “Advertising time” in the alternative complementary video / audio metadata, “Advertiser”, “Advertising time” in the advertisement presentation judgment metadata, and “Current date” in the personal characteristic information. ”,“ Current time ”and“ advertisement period ”and“ advertisement time ”in the advertisement determination metadata. A logical product of the results after each item comparison is calculated, and a plurality of true ones are selected as primary selection results.

  For the secondary selection, first, the “genre” and “subgenre” of the alternative complementary video / audio metadata and the “genre” and “subgenre” of the advertisement presentation determination metadata are selected. Are compared, and the logical product of the results after the comparison of each item is calculated. The keyword processing compares the “keyword” of the alternative complementary video / audio metadata with the “keyword” of the advertisement determination presentation metadata, and counts the number of keyword matches. In the secondary selection result, a plurality of scored points are selected according to the number of matching keywords.

  In the tertiary selection, the secondary selection result having the highest score is selected. When there is no selection candidate in the process of primary selection, secondary selection, and tertiary selection, the alternative complementary video / audio presence / absence determination result is no alternative complementary video / audio. The details of the alternative complementary video / audio search processing will be described later.

  Next, based on the search result of the alternative complementary video / audio, it is determined whether there is a corresponding alternative complementary video / audio (step Sb6). If there is a corresponding alternative complementary video / audio, the alternative complementary video / audio is reproduced. (Step Sb7). On the other hand, if there is no corresponding alternative complement video / audio, the streaming playback unit 210 continues to play the advertising content video / audio in the above-described step Sb8.

  Next, FIG. 10 is a flowchart for explaining an example of the above-described quality-complementary video / audio search processing (Sb2) according to the present embodiment. First, the quality-complementary video / audio metadata is acquired (step Sc1), and the number of download files is counted and set to n (step Sc2). Next, the loop counter i is set to “1” (step Sc3), and the following steps Sc4 to Sc11 are repeatedly executed for the number of download files n.

  First, the i-th download file is acquired (step Sc5), and advertisement presentation determination metadata is acquired (step Sc6). Next, it is determined whether or not the “advertiser” of the quality-complementary video / audio metadata and the “advertiser” of the advertisement presentation determination metadata match (step Sc7). It is determined whether the “advertising title” of the quality-complementary video / audio metadata matches the “advertising title” of the advertisement presentation determination metadata (step Sc8). It is determined whether or not the “advertisement time” of the audio metadata matches the “advertisement time” of the advertisement presentation determination metadata (step Sc9).

  If any one of the above determinations does not match (NO in step Sc7 or NO in step Sc8 or NO in step Sc9), the loop counter i is incremented by “1” (step Sc10), and step Sc11. In step Sc4, the same processing is repeated for the next download file.

  On the other hand, if all the items match in the above determination (YES in step Sc7 and YES in step Sc8 and YES in step Sc9), the download file at that time, that is, the file name of the i-th download file is recorded. (Step Sc13), the process proceeds to Step Sb3 in FIG.

  As described above, each item of the quality-complementary video / audio metadata and the advertisement presentation determination metadata is sequentially added to the download file while incrementing the loop counter i by “1” until the download file number n is repeated. The downloaded files that match all are selected as the quality-complementary video / audio of the advertising video / audio in the stream video / audio, and are reproduced instead of the streaming video / audio (advertisement video / audio).

  11 to 13 are flowcharts for explaining an example of the above-described alternative complementary video / audio search processing (Sb5) according to the present embodiment. First, alternative complementary video / audio metadata is acquired (step Sd1), "current date" and "current time" are acquired from the personal characteristic information (step Sd2), the number of downloaded files is counted, and set to n (step). Sd3). Next, the loop counter i is set to “1” (step Sd4), and the following steps Sd5 to Sd14 are repeatedly executed for the number of download files n.

  First, the i-th download file is acquired (step Sd6), and advertisement presentation determination metadata is acquired (step Sd7). Next, it is determined whether or not the “advertiser” of the alternative complementary video / audio metadata matches the “advertiser” of the advertisement presentation determination metadata (step Sd8). It is determined whether or not the “advertising time” of the alternative complementary video / audio metadata matches the “advertising time” of the advertisement presentation determination metadata (step Sd9). Is compared with the “advertisement period” of the advertisement determination metadata to determine whether the current date is within the advertisement period (step Sd10). If the current date is within the advertisement period, Further, the “current time” of the personal characteristic information and the “advertisement time” of the advertisement determination metadata are compared to determine whether the current time is the advertisement time (step Sd11).

  If any one of the above determinations does not match (NO in step Sd8, NO in step Sd9 or NO in step Sd10, or NO in step Sd11), the loop counter i is incremented by “1” (step Sd8). Sd13), returning to step Sd5 in step Sd14, the same processing is repeated for the next download file.

  On the other hand, if all items match in the above determination (YES in step Sd8 and YES in step Sd9 and YES in step Sd10 and YES in step Sd11), the file name of the i-th download file is recorded (step In step Sd12), the loop counter i is incremented by “1” in step Sd13 described above, the process returns to step Sd5 in step Sd14, and the same processing is repeated for the next download file.

  When the processing for the number of download files (n times) is completed, the presence / absence of recorded download file names, the number recorded, and the file names are output (step Sd15). Thereby, the primary selection result mentioned above is obtained.

  Next, the number of primary selection results is counted and set to n (step Sd16). Next, it is determined whether or not the number of primary selection results n is zero, that is, no selection has been made (step Sd17). If the number of primary selection results n is zero, “NO” is determined in step Sb6 of FIG. 9 described above. Thus, the process proceeds to step Sb8, and the advertising content video / audio is reproduced.

  On the other hand, if the number n of primary selection results is not zero, that is, if at least one download file is selected, personal characteristic information “genre”, “sub-genre”, and “keyword” are acquired (step Sd18). . Next, the loop counter i is set to “1” (step Sd19), and the following steps Sd20 to Sd28 are repeatedly executed for the number of primary selection results n.

  First, the i-th download file in the primary selection result is acquired (step Sd21), and advertisement presentation determination metadata is acquired (step Sd22). Next, it is determined whether or not the “genre” of the personal characteristic information matches the “genre” of the advertisement presentation determination metadata (step Sd23). It is determined whether or not “genre” matches the “sub-genre” of the advertisement presentation determination metadata (step Sd24).

  If even one of the above determinations does not match (NO in step Sd23 or NO in step Sd24), the loop counter i is incremented by “1” (step Sd27), and the process returns to step Sd20 in step Sd28. The same process is repeated for the downloaded file of the primary candidate result.

  On the other hand, if all items match in the above determination (YES in step Sd23 and YES in step Sd24), the number of keyword matches is counted (step Sd25), and the i-th download file name and the number of keyword matches are calculated. Record (step Sd26), increment the loop counter i by “1” in step Sd27 described above, return to step Sd20 in step Sd28, and repeat the same processing for the next download file.

  When the processing for the number of primary selection results (n times) is completed, the presence / absence, number of keyword downloads, number of keyword matches, and file names are output (step Sd29). As a result, a plurality of points selected according to the number of matching keywords are selected as the secondary selection results described above.

  Next, the number of secondary selection results is counted and set to n (step Sd30). Next, it is determined whether or not the number n of secondary selection results is zero, that is, no one has been selected (step Sd31). If the number n of secondary selection results is zero, the above-described step Sb6 in FIG. NO ", the process proceeds to step Sb8, and the advertising content video / audio is reproduced.

  On the other hand, if the number of secondary selection results n is not zero, that is, if at least one download file is selected in the primary selection, the loop counter i is set to “1” (step Sd32), and the secondary selection result The i-th file name and the number of keyword matches are acquired and stored in File_cmp (step Sd33). Next, the loop counter i is incremented by “1” (step Sd34), and the next steps Sd35 to Sd40 are repeatedly executed for the number n of secondary selection results.

  First, the i-th file name and keyword matching number in the secondary selection result are acquired and stored in File_tmp (step Sd36). At this time, since the loop counter i has already been incremented by “1”, File_cmp in Step Sd33 and File_tmp in Step S36 match the file name and keyword of different download files in the secondary selection result. Note that it is a number.

  Next, it is determined whether the keyword match number of File_tmp is larger than the keyword match number of File_cmp (step Sd37). If the number of keyword matches in File_tmp is smaller (NO in step Sd37), the loop counter i is incremented by “1” (step Sd38), the process returns to step Sd35 in step Sd40, and the next secondary candidate result is obtained. Repeat the process for the downloaded file.

  On the other hand, if the number of keyword matches of File_tmp is larger (YES in step Sd37), the contents of File_tmp are copied to File_cmp (step Sd39), the process returns to step Sd35 in step Sd40, and the download file of the next secondary candidate result Repeat the same process for.

  By repeating the above steps Sd35 to Sd40, the file name and the keyword matching number of the download file having the largest keyword matching number among the secondary candidates remain in File_cmp.

  When the processing for the number of secondary selection results (n times) is completed, the presence or absence of the search result or the contents of File_cmp (the file name of the download file finally remaining as the tertiary selection candidate) is output (step Sd41). ). As a result of the secondary selection, the secondary selection result having the highest score (keyword matching number) is selected.
