[0127] 番組選択装置 100は、所定の手段により記録媒体 123を検知すると（S2001で Ye s)、第 2地理情報取得部 109は、記録媒体 123に記録されている地理座標を示す情 報を第 2地理情報として読み出す（S 2002)。 [0127] When the program selection device 100 detects the recording medium 123 by a predetermined means (Yes in S2001), the second geographic information acquisition unit 109 receives information indicating the geographic coordinates recorded in the recording medium 123. Read out as second geographic information (S 2002).
[0128] また、記録媒体 123を検知しない場合（S2001で No)、検知を待って地理座標を 示す情報を読み出す。 [0128] If the recording medium 123 is not detected (No in S2001), the information indicating the geographical coordinates is read after the detection.
[0129] このように、番組選択装置 100は、ユーザの位置を示す第 2地理情報を取得する。  As described above, the program selection device 100 acquires the second geographic information indicating the position of the user.
[0130] 図 11は、第 1地理情報と第 2地理情報との比較および番組選択に係る処理につい てのフローチャートである。当該フローチャートは、図 8における地理情報の比較およ び番組選択処理（S 3000)の詳細を表している。 [0130] FIG. 11 is a flowchart of processing relating to comparison between first geographic information and second geographic information and program selection. The flowchart shows details of the comparison of geographic information and the program selection process (S3000) in FIG.
[0131] まず、比較部 111は、第 1地理情報取得部 107が取得した第 1地理情報と、第 2地 理情報取得部 109が取得した第 2地理情報とを比較する（S 3001 )。 [0131] First, the comparison unit 111 compares the first geographic information acquired by the first geographic information acquisition unit 107 with the second location. The second geographic information acquired by the physical information acquisition unit 109 is compared (S 3001).
[0132] 地理条件番組選択部 112は、この比較の結果から、第 2地理情報と所定の関係に ある第 1地理情報を特定する。さらに、特定した第 1地理情報に対応する AVデータ を選択する（S3002)。 [0132] From the result of this comparison, the geographic condition program selection unit 112 identifies the first geographic information having a predetermined relationship with the second geographic information. Further, AV data corresponding to the identified first geographic information is selected (S3002).
[0133] 本実施の形態においては、比較部 111は、具体的には、第 2地理情報に示される 地理座標と、複数の第 1地理情報に示されるそれぞれの地理座標とを比較し、それら の距離を求める。  [0133] In the present embodiment, the comparison unit 111 specifically compares the geographic coordinates indicated in the second geographic information with the geographic coordinates indicated in the plurality of first geographic information, and compares them. Find the distance.
[0134] また、地理条件番組選択部 112は、第 2地理情報に示される地理座標と、最も近い 地理座標を示す第 1地理情報を特定する。さらに、特定した第 1地理情報に対応す る AVデータの番組 IDを選択する。  [0134] Further, the geographic condition program selection unit 112 identifies the geographic coordinates indicated by the second geographic information and the first geographic information indicating the nearest geographic coordinates. Furthermore, the program ID of AV data corresponding to the specified first geographic information is selected.
[0135] 本例の場合、記録媒体 123から読み出した第 2地理情報は、経度： 132度 10分 58 秒 5000、緯度： 36度 00分 35秒 5000を示して!/、る。 In this example, the second geographic information read from the recording medium 123 indicates longitude: 132 degrees 10 minutes 58 seconds 5000 and latitude: 36 degrees 00 minutes 35 seconds 5000! /
[0136] この場合、図 7より、この地理座標に最も近い地理座標は番組 ID1— 1の経度： 132 度 10分 58秒 0000、緯度： 36度 00分 35秒 0000である。これにより、地理条件番組 選択部 112は、番組 ID1— 1を選択する。 In this case, from FIG. 7, the geographical coordinates closest to this geographical coordinate are the longitude of program ID 1-1: 132 degrees 10 minutes 58 seconds 0000 and latitude: 36 degrees 00 minutes 35 seconds 0000. Thereby, the geographic condition program selection unit 112 selects the program ID 1-1.
[0137] 地理条件番組選択部 112は、番組 IDを選択すると、番組 IDに対応する番組情報 を番組情報記憶部 106から読み出す（S3003)。 [0137] When the geographic condition program selection unit 112 selects a program ID, the program information corresponding to the program ID is read from the program information storage unit 106 (S3003).
[0138] AVデコ一ド部 104は、地理条件番組選択部 112に読み出された番組情報に対応 する AVデータを映像データと音声データとの同期を取りながら復号する。 [0138] The AV decode unit 104 decodes the AV data corresponding to the program information read by the geographic condition program selection unit 112 while synchronizing the video data and the audio data.
[0139] AVデコード部 104により得られた映像データおよび音声データは、 AV出力部 10[0139] The video data and audio data obtained by the AV decoding unit 104 are stored in the AV output unit 10

[0140] ここで、 2つの地理座標間の距離を求める方法について説明する。まず、赤道面の 半径を 6378137. 00mとし、極方向の半径力 6356752. 31mとして計算する場合 を想定する。 [0140] Here, a method for obtaining the distance between two geographic coordinates will be described. First, assume that the radius of the equatorial plane is 6378137.00m and the radial force is 6356752.31m.
[0141] この場合、 GPSから得られる経度の 1秒あたりの距離は約 30. 9mとなり、緯度の 1 秒あたりの距離は 24. 7mとなる。  [0141] In this case, the distance per second of longitude obtained from GPS is about 30.9 m, and the distance per second of latitude is 24.7 m.
[0142] これらの値から、図 6を参照しながら距離を計算する。はじめに、ユーザの座席位置 [0142] From these values, the distance is calculated with reference to FIG. First, the seat position of the user

3m、点、泉 407の長さは約 108. 85m、点、泉 408の長さは約 47. 97mとなる。 The length of 3m, point and spring 407 is about 108.85m, and the length of point and spring 408 is about 47.97m.
[0146] 以上の計算結果から、ユーザの座席位置 309からの距離が最も短い点線は 19. 7[0146] From the above calculation results, the dotted line with the shortest distance from the seat position 309 of the user is 19.7.
8mの点線 401となる。これにより、地理条件番組選択部 112は、カメラ 301について の第 1地理情報力 複数の第 1地理情報の中で、ユーザの座席位置 309に最も近い 位置を示すものであると特定できる。 The dotted line 401 is 8m. As a result, the geographic condition program selection unit 112 can specify that the first geographic information power of the camera 301 indicates the position closest to the seat position 309 of the user among the plurality of first geographic information.
[0147] なお、この特定までを比較部 111が行ってもよい。この場合、比較部 111は、上記 の特定の結果を比較の結果として、地理条件番組選択部 112に通知すればよい。 Note that the comparison unit 111 may perform the process up to this specification. In this case, the comparison unit 111 may notify the geographic condition program selection unit 112 of the specific result as a comparison result.

[0165] 具体的には、携帯端末 150は、複数の中からユーザに適した番組を選択する番組 選択装置 100aを備え、番組選択装置 100aにより選択された番組をユーザに提示す るための表示装置 120およびスピーカ 121を備えている。 [0165] Specifically, the mobile terminal 150 includes a program selection device 100a that selects a program suitable for the user from among a plurality, and a display for presenting the program selected by the program selection device 100a to the user A device 120 and a speaker 121 are provided.
[0166] また、ユーザが携帯端末 150に各種の指示を与えるための複数のボタン等からなる 入力デバイス 122を備えている。 [0166] In addition, an input device 122 including a plurality of buttons and the like for the user to give various instructions to the mobile terminal 150 is provided.
[0167] 図 13は、実施の形態 2における携帯端末 150の機能ブロック図である。 FIG. 13 is a functional block diagram of mobile terminal 150 in the second embodiment.
[0168] なお、図 13において、携帯端末 150が有する通話機能等についての機能ブロック は省略し、実施の形態 2において特徴的な構成について説明する。 [0168] Note that, in FIG. 13, functional blocks for the call function and the like possessed by mobile terminal 150 are omitted, and a characteristic configuration in Embodiment 2 will be described.
[0169] 図 13に示すように、携帯端末 150が備える番組選択装置 100aは、図 1に示す実 施の形態 1における番組選択装置 100と同様の機能構成である。 As shown in FIG. 13, program selection device 100a provided in portable terminal 150 has the same functional configuration as program selection device 100 in the first embodiment shown in FIG.
[0170] しかしながら、携帯端末 150が備える番組選択装置 100aは、 GPS受信装置 130か ら第 2地理情報を取得する点で、実施の形態 1における番組選択装置 100とは異な つている。 [0170] However, program selection device 100a included in portable terminal 150 is different from program selection device 100 in the first embodiment in that the second geographic information is acquired from GPS reception device 130.
[0171] なお、 GPS受信装置 130は、携帯端末 150の位置情報である地理座標を取得す るが、携帯端末 150がユーザに携帯されている場合、当該地理座標は実質的にはュ 一ザの位置を示す情報である。  [0171] Note that the GPS receiving device 130 acquires geographical coordinates that are position information of the mobile terminal 150. However, when the mobile terminal 150 is carried by a user, the geographical coordinates are substantially the same as the user. It is the information which shows the position of.
[0172] また、 GPS受信装置 130は、本発明の携帯端末における位置情報取得手段の一 例である。位置情報取得手段の別の例としては、地上に設置されたビーコンから信 号を受信することで自身の位置等の情報を取得する受信装置等がある。 [0172] Further, the GPS receiving device 130 is an example of position information acquisition means in the portable terminal of the present invention. As another example of the position information acquisition means, there is a receiving apparatus that acquires information such as its own position by receiving a signal from a beacon installed on the ground.
[0173] 携帯端末 150がこのような構成であることにより、番組選択装置 100aが番組を選択 する際に、例えば、その時点でのユーザの存在する地理的な位置を参照し、ユーザ に適した番組を選択することができる。 [0173] With the mobile terminal 150 having such a configuration, when the program selection device 100a selects a program, for example, the geographical position where the user exists at that time is referred to, so that it is suitable for the user. A program can be selected.
[0174] 図 14は、実施の形態 2における番組選択装置 100aが第 2地理情報を取得する際 の動作の流れを示すフローチャートである。 FIG. 14 is a flowchart showing an operation flow when the program selection device 100a in the second embodiment acquires the second geographic information.
[0175] 番組選択装置 100aが番組を選択する際、 GPS受信装置 130が緯度および経度を 受信すると（S2100で Yes)、第 2地理情報取得部 109は、 GPS受信装置 130から緯 度および経度を取得する（S2101)。 [0175] When the program selection device 100a selects a program, if the GPS receiving device 130 receives the latitude and longitude (Yes in S2100), the second geographic information acquisition unit 109 reads the latitude and longitude from the GPS receiving device 130. The degree and longitude are acquired (S2101).
[0176] また、 GPS受信装置 130が緯度および経度を受信しない場合、（S2100で No)、 受信を待って緯度および経度を取得する。 [0176] If the GPS receiver 130 does not receive the latitude and longitude (No in S2100), it waits for reception and acquires the latitude and longitude.
[0177] このようにして、番組選択装置 100aは、第 2地理情報である、ユーザの存在してい る緯度および経度を示す情報を取得する。 [0177] In this way, the program selection device 100a obtains information indicating the latitude and longitude where the user exists, which is the second geographic information.
[0178] なお、 GPS受信装置 130からの緯度および経度の取得は、例えば、ユーザの明示 の指示または、携帯端末 150の状態変化を契機として行ってもよぐもしくは、所定の 期間ごとなどに自動的に行ってもよい。 [0178] Note that the latitude and longitude from the GPS receiver 130 can be obtained, for example, in response to a user's explicit instruction or a change in the state of the mobile terminal 150, or automatically every predetermined period. It may be done automatically.
[0179] なお、複数の第 1地理情報は、実施の形態 1における番組選択装置 100と同じぐ 第 1地理情報取得部 107により取得される（図 9参照）。 Note that the plurality of pieces of first geographic information are acquired by the first geographic information acquisition unit 107 that is the same as that of the program selection device 100 in Embodiment 1 (see FIG. 9).
[0180] また、これら取得した第 1地理情報と第 2地理情報とを比較し、第 2地理情報に示さ れる位置に最も近い位置を示す第 1地理情報を特定することで、出力すべき番組を 選択する（図 11参照）。 [0180] Further, by comparing the acquired first geographic information with the second geographic information and identifying the first geographic information indicating the position closest to the position indicated in the second geographic information, the program to be output Select (see Figure 11).
[0181] これにより、その時点でユーザが存在している地理的な位置に最も近い位置で撮 影されてレ、る映像、または撮影された映像を含む番組が選択される。  [0181] Thus, a video that is captured at a position closest to the geographical location where the user is present at that time, or a program that includes the captured video is selected.
[0182] 例えば、実施の形態 1で説明したサッカーの試合の観戦中に、ユーザが携帯端末[0182] For example, during the watching of the soccer game described in Embodiment 1, the user
150を用いて当該サッカ一試合の生中継放送を視聴する場合を想定する。 Suppose that 150 is used to watch the live broadcast of the soccer game.
[0183] この場合、ユーザにチャンル選択の操作をさせることなぐユーザの視点に最も近 い視点からの映像を有する番組をユーザに提示することができる。 In this case, a program having a video from a viewpoint closest to the user's viewpoint without allowing the user to perform a channel selection operation can be presented to the user.
[0184] つまり、番組選択装置 100aは、ユーザが把握し易いと考えられる、ユーザが視覚 で捉える映像に最も近い映像の番組を、直接的に選択し出力することができる。 [0184] That is, the program selection device 100a can directly select and output a program that is considered to be easily grasped by the user and that is closest to the video captured by the user visually.
[0185] また、例えば、ユーザが観光地を歩いているときに、その観光地またはその近傍で 撮影された番組をユーザに即座に提示することも可能である。これにより、例えばュ 一ザが欲する情報を含む番組を直接的に選択し出力することができる。 [0185] Also, for example, when a user is walking around a sightseeing spot, a program shot at or near the sightseeing spot can be immediately presented to the user. Thereby, for example, a program including information desired by a user can be directly selected and output.
[0186] なお、実施の形態 2における番組選択装置 100aが、 GPS受信装置 130から第 2地 理情報を取得する機能に換えて、または、加えて、外部の記録媒体等から第 2地理 情報を取得する機能を有して!/、てもよレ、。 [0186] It should be noted that program selection device 100a in the second embodiment obtains the second geographic information from an external recording medium or the like instead of or in addition to the function of acquiring the second geographic information from GPS receiving device 130. Have the ability to get! /
[0187] つまり、実施の形態 1における番組選択装置 100のように、ユーザの存在していた 位置を示す情報またはユーザに指定された位置を示す情報を、第 2地理情報として 取得し、その位置と同一または近い位置に関連する番組を選択する機能を有してい てもよい。 [0187] That is, the user exists as in the program selection device 100 in the first embodiment. Information indicating the position or information indicating the position designated by the user may be acquired as the second geographic information, and a program related to a position that is the same as or close to the position may be selected.
[0188] また、第 2地理情報取得部 109が、 GPS受信装置 130に相当する機能を有してい てもよい。つまり、第 2地理情報取得部 109が、携帯端末 150の位置を示す位置情報 を取得する機能と、その位置情報を第 2地理情報として取得する機能とを有して!/、て あよい。  [0188] In addition, the second geographic information acquisition unit 109 may have a function corresponding to the GPS receiver 130. That is, the second geographical information acquisition unit 109 may have a function of acquiring position information indicating the position of the mobile terminal 150 and a function of acquiring the position information as second geographical information! /.
[0189] (実施の形態 3) [0189] (Embodiment 3)
本発明の実施の形態 3として、ユーザの指示により第 2地理情報を修正する機能を 有する番組選択装置 100bについて説明する。  As a third embodiment of the present invention, a program selection device 100b having a function of correcting the second geographic information according to a user instruction will be described.
[0190] なお、実施の形態 3における番組選択装置 100bの基本的な処理内容は実施の形 態 1における番組選択装置 100と同じである。 Note that the basic processing contents of program selection device 100b in the third embodiment are the same as those of program selection device 100 in the first embodiment.
[0191] すなわち、番組選択装置 100bは、 1以上の TSを受信しその 1以上の TSに含まれ る複数の AVデータの中から出力すべき AVデータを選択する。 That is, the program selection device 100b receives one or more TSs and selects AV data to be output from among a plurality of AV data included in the one or more TSs.
[0192] また、実施の形態 1における番組選択装置 100と同様に、番組選択装置 100bが S[0192] Also, similar to the program selection device 100 in the first embodiment, the program selection device 100b has S
TBとして実現されて!/、る場合を想定して説明する。 It is assumed that it is realized as TB!
[0193] また、図 4〜図 7の各図に示される各種の状況の設定および保持する情報の種類 等も実施の形態 3においても採用される力 S、これら図についての説明は省略する。 [0193] In addition, the setting of various situations shown in each of FIGS. 4 to 7, the type of information to be held, and the force S employed in the third embodiment are also omitted.
[0194] 実施の形態 3における番組選択装置 100bは、上述の修正機能を有することにより[0194] The program selection device 100b in the third embodiment has the above-described correction function.
、例えばユーザがサッカー場で観戦したサッカーの試合の録画放送を家で視聴する 場合に、ユーザが体感した視点の映像とは異なる視点からの映像を含む番組を直接 的に選択することができる。 For example, when watching a recorded broadcast of a soccer game that the user watched on a soccer field at home, it is possible to directly select a program including a video from a viewpoint different from the video of the viewpoint experienced by the user.
[0195] 図 15は、実施の形態 3における番組選択装置 100bの機能ブロック図である。 FIG. 15 is a functional block diagram of program selection device 100b in the third embodiment.
[0196] 図 15に示す番組選択装置 100bの機能的な構成は、基本的には図 1に示す番組 選択装置 100と同様である。 [0196] The functional configuration of the program selection device 100b shown in FIG. 15 is basically the same as that of the program selection device 100 shown in FIG.
[0197] しかし、記録媒体 123から読み取った地理座標を、ユーザの指定した方位、距離に 従って修正する修正部 115を備える点で実施の形態 1における番組選択装置 100と は異なっている。 [0198] そこで、修正部 115の動作を図 16のフローチャートに基づいて説明する。 However, it differs from program selection device 100 in Embodiment 1 in that it includes a correction unit 115 that corrects the geographical coordinates read from recording medium 123 according to the direction and distance designated by the user. [0198] The operation of the correcting unit 115 will be described based on the flowchart of FIG.
[0199] 図 16は、修正部 115による処理の流れを示すフローチャートである。 FIG. 16 is a flowchart showing the flow of processing by the correction unit 115.
[0200] なお、記録媒体 123に記録されて!/、る地理座標が、第 2地理情報として第 2地理情 報取得部 109に読み取られており、その第 2地理情報に対して図 16に示す処理がな される。 [0200] The geographic coordinates recorded in the recording medium 123 are read as second geographic information by the second geographic information acquisition unit 109, and the second geographic information is shown in FIG. The processing shown is done.
[0201] まず、修正部 115は、ユーザからの、第 2地理情報の修正指示を受けた場合（S40 [0201] First, the correction unit 115 receives a correction instruction for the second geographic information from the user (S40).
01で Yes)、その指示内容を取得する（S4002)。さらに、その指示内容に従い当該 地理座標を修正する（S4003)。 If YES at 01), the contents of the instruction are acquired (S4002). Further, the geographical coordinates are corrected according to the contents of the instruction (S4003).
[0202] 例えば、ユーザの入力デバイス 122の操作により、 "東に 50m"を示す情報が入力 された場合、修正部 115は、第 2地理情報を、当初の地理座標から東に 50mだけ離 れた地点を示す情報に修正する。 [0202] For example, when information indicating "50 m to the east" is input by the operation of the user's input device 122, the correction unit 115 separates the second geographic information from the original geographical coordinates by 50 m to the east. It corrects to the information which shows the point.
[0203] 比較部 111は、修正部 115により修正された第 2地理情報と、第 1地理情報取得部[0203] The comparison unit 111 includes the second geographic information modified by the modification unit 115 and the first geographic information acquisition unit.
107より取得された複数の第 1地理情報とを比較する。 Compare multiple pieces of first geographic information obtained from 107.
[0204] 具体的には、修正後の第 2地理情報に示される位置と、それぞれの第 1地理情報 に示される位置との距離を算出する。 [0204] Specifically, the distance between the position indicated in the corrected second geographic information and the position indicated in each first geographic information is calculated.
[0205] 地理条件番組選択部 112は、この算出結果から、修正後の第 2地理情報に示され る位置に最も近い位置を示す第 1地理情報を特定する。さらに、その第 1地理情報に 対応する番組を選択する。 From the calculation result, the geographical condition program selection unit 112 specifies the first geographical information indicating the position closest to the position indicated in the corrected second geographical information. In addition, the program corresponding to the first geographic information is selected.
[0206] なお、修正指示を受けない場合（S4001で No)は、修正処理は行わない。 [0206] If no correction instruction is received (No in S4001), the correction process is not performed.
[0207] このように、実施の形態 3における番組選択装置 100bは修正部 115を備える。この 修正部 115は、ユーザの指示に従い、記録媒体 123から読み取られた第 2地理情報 を修正する。 As described above, the program selection device 100b according to Embodiment 3 includes the correcting unit 115. The correction unit 115 corrects the second geographic information read from the recording medium 123 according to the user's instruction.
[0208] これにより、例えば、ユーザがサッカー観戦で体感した臨場感とは異なる視点から の当該サッカー試合の録画放送を楽しむことが出来る。  [0208] Thereby, for example, it is possible to enjoy the recorded broadcast of the soccer game from a viewpoint different from the realistic sensation experienced by the user in the soccer game.
[0209] なお、図 16に示される第 2地理情報の修正処理のタイミングは、番組の選択処理（ 図 9参照）の後に行ってもよい。 Note that the timing of the second geographic information correction process shown in FIG. 16 may be performed after the program selection process (see FIG. 9).
[0210] また、ユーザの修正指示の内容は、方向および距離に限られない。例えば、単に"[0210] The contents of the user's correction instruction are not limited to the direction and the distance. For example, simply "
50m"という指示内容でもよい。この場合、修正部 115は、第 2地理情報を、記録媒 体 123から取得された地理座標を中心とする半径 50mの円を示す情報に修正する。 In this case, the correction unit 115 stores the second geographic information in the recording medium. The information is corrected to indicate a circle with a radius of 50 m centered on the geographical coordinates obtained from the body 123.
[0211] また、比較部 111は、当該円と、それぞれの第 1地理情報に示される位置との最短 距離を計算する。また、地理条件番組選択部 112は、当該円に最も近い位置を示す 第 1地理情報を特定し、その第 1地理情報に対応する番組を選択する。 [0211] Further, the comparison unit 111 calculates the shortest distance between the circle and the position indicated by the first geographic information. In addition, the geographic condition program selection unit 112 identifies first geographic information indicating a position closest to the circle, and selects a program corresponding to the first geographic information.
[0212] これにより、例えば、ユーザは、おおよその距離のみを指示するだけで、その指示さ れた距離に応じて変更された視点からの映像の番組を、番組選択装置 100bに選択 させること力 Sでさる。 [0212] Thus, for example, the user can designate only the approximate distance, and the program selection device 100b can select the video program from the viewpoint changed according to the designated distance. Touch with S.
[0213] また、実施の形態 3における番組選択装置 100bは、 STBとして実現されているとし たが、実施の形態 2における番組選択装置 100aと同じぐ携帯端末等の機器に備え られていてもよい。  [0213] Further, program selection apparatus 100b in the third embodiment is realized as an STB, but may be provided in a device such as a portable terminal similar to program selection apparatus 100a in the second embodiment. .
[0214] (実施の形態 4) [0214] (Embodiment 4)
本発明の実施の形態 4として、ユーザの指示により比較部 111における比較の精度 を変更する機能を有する番組選択装置 100cについて説明する。  As a fourth embodiment of the present invention, a program selection device 100c having a function of changing the accuracy of comparison in the comparison unit 111 according to a user instruction will be described.
[0215] なお、実施の形態 4における番組選択装置 100cの基本的な処理内容は実施の形 態 1における番組選択装置 100と同じである。 [0215] The basic processing contents of program selection device 100c in the fourth embodiment are the same as those of program selection device 100 in the first embodiment.
[0216] すなわち、番組選択装置 100cは、 1以上の TSを受信しその 1以上の TSに含まれ る複数の AVデータの中から出力すべき AVデータを選択する。 That is, the program selection device 100c receives one or more TSs and selects AV data to be output from among a plurality of AV data included in the one or more TSs.
[0217] また、実施の形態 2における番組選択装置 100aと同様に、番組選択装置 100cが 携帯端末 151に備えられて!/、る場合につ!/、て説明する。 [0217] Similarly to the program selection device 100a in the second embodiment, the case where the program selection device 100c is provided in the portable terminal 151 will be described.
[0218] 図 17は、実施の形態 4における携帯端末 151の機能ブロック図である。 FIG. 17 is a functional block diagram of mobile terminal 151 in the fourth embodiment.
[0219] 図 17に示すように、携帯端末 151は、番組選択装置 100cを備えている。 [0219] As shown in FIG. 17, the portable terminal 151 includes a program selection device 100c.
[0220] 携帯端末 151は、実施の形態 2における携帯端末 150と同じぐ携帯電話であり、 通常の電話としての機能に加え、テレビ放送を受信し映像および音声を出力する機 能を有している。 [0220] The mobile terminal 151 is the same mobile phone as the mobile terminal 150 in Embodiment 2, and has a function of receiving a TV broadcast and outputting video and audio in addition to the function of a normal telephone. Yes.
[0221] なお、図 17において、携帯端末 151が有する通話機能等についての機能ブロック は省略し、実施の形態 4において特徴的な構成について説明する。  [0221] Note that in Fig. 17, functional blocks for the call function and the like possessed by mobile terminal 151 are omitted, and a characteristic configuration in Embodiment 4 will be described.
[0222] 携帯端末 151が備える番組選択装置 100cの機能的な構成は、基本的には図 1に 示す番組選択装置 100と同様である。 [0223] しかし、ユーザの指示により、第 1地理情報と第 2地理情報との比較における比較 精度を変更する比較精度変更部 116を備える点で実施の形態 1における番組選択 装置 100とは異なっている。 [0222] The functional configuration of the program selection device 100c included in the mobile terminal 151 is basically the same as that of the program selection device 100 shown in FIG. [0223] However, it differs from program selection device 100 in Embodiment 1 in that it includes a comparison accuracy changing unit 116 that changes the comparison accuracy in the comparison between the first geographic information and the second geographic information in accordance with a user instruction. Yes.
[0224] なお、本実施の形態における"比較精度"とは、位置を示す 2つの情報の一致性の 判断における幅、つまり許容範囲である。  [0224] Note that "comparison accuracy" in the present embodiment is a width, that is, an allowable range in determining the coincidence of two pieces of information indicating positions.
[0225] 例えば、ユーザから" lKm"と指示された場合を想定する。この場合、ある第 1地理 情報に示される位置と、第 2地理情報に示される位置（一点または所定の範囲）との 差が lKm以内であれば、当該第 1地理情報に示される位置は、当該第 2地理情報 に示される位置に一致する、または該当すると判断することを意味する。  [0225] For example, it is assumed that the user instructs "lKm". In this case, if the difference between the position indicated by certain first geographic information and the position indicated by the second geographic information (one point or a predetermined range) is within lKm, the position indicated by the first geographic information is This means that it matches or corresponds to the position indicated in the second geographic information.
[0226] また、本実施の形態においては、図 18に示す複数の放送が行われている場合を 想定する。  [0226] Further, in the present embodiment, it is assumed that a plurality of broadcasts shown in Fig. 18 are being performed.
[0227] 図 18は、実施の形態 4における、複数の番組と各番組の撮影位置を示す地理座標 との対応を示す図である。  [0227] FIG. 18 is a diagram illustrating a correspondence between a plurality of programs and geographic coordinates indicating shooting positions of the programs in the fourth embodiment.
[0228] 図 18に示すように、時計台で撮影した番組は経度： 140度 15分 24秒 1234、緯度: [0228] As shown in Figure 18, the program shot on the clock tower is longitude: 140 degrees 15 minutes 24 seconds 1234, latitude:

[0229] つまり、それぞれの番組は、それぞれの撮影位置または撮影対象物の位置を示す 地理座標と対応づけられてレヽる。 [0229] That is, each program is recorded in association with the geographical coordinates indicating the respective photographing positions or the positions of the photographing objects.
[0230] また、これら番組を構成する AVデータには、これら地理座標を示す情報が多重化 されている。  [0230] In addition, information indicating these geographical coordinates is multiplexed in AV data constituting these programs.
[0231] これら複数の番組は、 1つまたは複数の TSに含まれて送信され、本実施の形態に おける番組選択装置 100cによって受信される。  [0231] The plurality of programs are included and transmitted in one or more TSs, and are received by the program selection device 100c in the present embodiment.
[0232] また、番組選択装置 100cでは、第 1地理情報取得部 107によって、これら地理座 標が第 1地理情報として取得され、番組地理情報テーブル 108が生成される。 [0232] Also, in the program selection device 100c, the first geographic information acquisition unit 107 acquires these geographic coordinates as the first geographic information, and the program geographic information table 108 is generated.
[0233] 図 19は、実施の形態 4における第 1地理情報取得部 107により生成された番組地 理情報テーブル 108の一例を示す図である。 FIG. 19 is a diagram showing an example of the program geographic information table 108 generated by the first geographic information acquisition unit 107 in the fourth embodiment.
[0234] 図 19に示す番組地理情報テーブル 108に含まれる、番組 ID、地理情報種別、お よび第 1地理情報は、上述の実施の形態 1と同じぐそれぞれの AVデータに付随す る番組情報から取得されたものである。 [0234] The program ID, geographic information type, and program included in the program geographic information table 108 shown in FIG. The first geographic information is obtained from the program information associated with each AV data as in the first embodiment.
[0235] また、各番組には、；!〜 Nの番組 IDが付され、番組 IDにより識別できるようになって おり、それぞれの第 1地理情報は、図 18に示した地理座標である。 [0235] Each program is given a program ID;! -N, and can be identified by the program ID. The first geographic information of each program is the geographic coordinates shown in FIG.
[0236] なお、番組のロケ地を表す地理座標は、 1つの番組 IDに複数対応付けられていて もよい。例えば、 1つの番組が複数のロケ地で撮影された映像を含む場合、それら口 ケ地を特定する複数の地理座標が、当該番組の番組 IDと対応付けられて!/、てもよ!/、 [0236] It should be noted that a plurality of geographic coordinates representing the location of a program may be associated with one program ID. For example, if a single program contains videos shot at multiple locations, multiple geographic coordinates that identify these locations are associated with the program ID of that program! / ,
[0237] なお、図 19に示す番組地理情報テーブル 108を生成する際の処理の流れは実施 の形態 1における処理の流れと同じである（図 9参照）。 [0237] The process flow when generating the program geographic information table 108 shown in Fig. 19 is the same as the process flow in the first embodiment (see Fig. 9).
[0238] また、第 2地理情報である地理座標も、実施の形態 1と同じぐ第 2地理情報取得部 [0238] Also, the second geographic information acquisition unit having the same geographic coordinates as the second geographic information as in the first embodiment.
109により記録媒体 123から読み出される（図 10参照）。  109 is read from the recording medium 123 (see FIG. 10).
[0239] このようにして取得された複数の番組それぞれについての地理座標（第 1地理情報[0239] Geographic coordinates (first geographic information) for each of the multiple programs acquired in this way
)と、第 2地理情報とは比較部 111により比較される。 ) And the second geographic information are compared by the comparison unit 111.
[0240] 本実施の形態の番組選択装置 100cでは、この比較の際、ユーザからの指示による 変更後の精度で比較を行うことができる。この比較精度の変更に係る処理の流れを 図 20を用いて説明する。 [0240] In the program selection device 100c of the present embodiment, at the time of this comparison, the comparison can be performed with the accuracy after the change according to the instruction from the user. The flow of processing related to this change in comparison accuracy will be described with reference to FIG.
[0241] 図 20は、比較精度変更部 116による処理の流れを示すフローチャートである。 FIG. 20 is a flowchart showing the flow of processing by the comparison accuracy changing unit 116.
[0242] まず、ユーザから比較精度を変更する指示を受けた場合（S 5001で Yes)、その指 示内容を取得する（S5002)。さらに、その指示内容に従い、比較部 111における比 較精度を変更する（S5003)。 [0242] First, when an instruction to change the comparison accuracy is received from the user (Yes in S5001), the instruction content is acquired (S5002). Further, the comparison accuracy in the comparison unit 111 is changed according to the instruction content (S5003).
[0243] 具体的には、比較精度変更部 116は、第 2地理情報に示される位置から指示され た距離以内の地理座標は、第 2地理情報と一致すると判断するように比較精度を変 更する。 [0243] Specifically, the comparison accuracy changing unit 116 changes the comparison accuracy so as to determine that the geographic coordinates within the distance indicated from the position indicated in the second geographic information match the second geographic information. To do.
[0244] 例えば、ユーザによる入力デバイス 122の操作により、 "lKm"を示す情報が入力さ れた場合を想定する。この場合、比較精度変更部 116は比較部 111における比較精 度を lKm以内を許容範囲とする精度に変更する。  [0244] For example, it is assumed that information indicating "lKm" is input by the user operating the input device 122. In this case, the comparison accuracy changing unit 116 changes the comparison accuracy in the comparison unit 111 to an accuracy within an allowable range within lKm.
[0245] これにより、比較部 111は、第 2地理情報に示される位置を中心とする半径 lKm以 内の地理座標は第 2地理情報に一致すると判断する。 [0245] As a result, the comparison unit 111 has a radius less than lKm centered on the position indicated by the second geographic information. It is determined that the geographic coordinates in the match the second geographic information.
[0246] なお、比較精度を変更する指示を受けなかった場合（S5001で No)は、この比較 精度の変更処理は行わなレ、。 [0246] If the instruction to change the comparison accuracy is not received (No in S5001), this comparison accuracy change processing is not performed.
[0247] このように、実施の形態 4における番組選択装置 100c比較精度変更部 116を備え る。この比較精度変更部 116は、ユーザの指示に従い、比較部 111における比較精 度を変更する。 [0247] Thus, the program selection device 100c comparison accuracy changing unit 116 in the fourth embodiment is provided. The comparison accuracy changing unit 116 changes the comparison accuracy in the comparison unit 111 in accordance with a user instruction.
[0248] これにより、例えば、ユーザが、自身が存在していた位置を中心とする所定の範囲 内に関する情報を所望する場合に、容易に当該情報を含む番組を視聴することが可 能となる。  [0248] Thus, for example, when the user desires information related to a predetermined range centered on the position where the user existed, it is possible to easily view a program including the information. .
[0249] なお、この比較精度変更処理のタイミングは、記録媒体 123からの第 2地理情報の 取得前に行ってもよぐ一旦、番組を選択した後に行ってもよい。  [0249] The timing of the comparison accuracy changing process may be performed before the acquisition of the second geographic information from the recording medium 123, or may be performed once a program is selected.
[0250] また、例えば、第 2地理情報に示される位置に一致する第 1地理情報がある場合は 、当該第 1地理情報に対応する番組を選択する。また、そのような第 1地理情報がな V、場合は、ユーザに比較精度の変更を行わせるようにしてもょレ、。  [0250] For example, if there is first geographic information that matches the position indicated by the second geographic information, the program corresponding to the first geographic information is selected. Also, if such first geographic information is not V, let the user change the comparison accuracy.
[0251] 図 21は、番組選択装置 100cが、第 2地理情報に一致する番組がない場合に、ュ 一ザの指示により比較精度の変更を行う場合の処理の流れを示すフローチャートで ある。  FIG. 21 is a flowchart showing the flow of processing when the program selection device 100c changes the comparison accuracy in accordance with a user instruction when there is no program that matches the second geographic information.
[0252] 図 22および図 23は、図 21に示す処理の流れにおいて表示される画面例を示す図 である。  FIG. 22 and FIG. 23 are diagrams showing examples of screens displayed in the processing flow shown in FIG.
[0253] 図 21〜図 23を用いて、携帯端末 151の番組選択装置 100cの比較精度の変更を 伴う処理の流れを説明する。  [0253] With reference to FIG. 21 to FIG. 23, a description will be given of the flow of processing that involves changing the comparison accuracy of the program selection device 100c of the mobile terminal 151.
[0254] 第 1地理情報取得部 107は、 1以上の TSから複数の AVデータのそれぞれに関連 する第 1地理情報を取得する（S6001)。本例においては、図 18に示すような地理座 標を取得する。また、これら地理情報を取得後に、上述のように地理情報テーブルを 生成する。 [0254] The first geographic information acquisition unit 107 acquires the first geographic information related to each of the plurality of AV data from one or more TSs (S6001). In this example, geographical coordinates as shown in Fig. 18 are acquired. In addition, after acquiring these geographic information, a geographic information table is generated as described above.
[0255] 第 2地理情報取得部 109は、記録媒体 123からユーザの位置を示す第 2地理情報 を取得する（S6002)。  [0255] The second geographic information acquisition unit 109 acquires the second geographic information indicating the position of the user from the recording medium 123 (S6002).
[0256] 本例におレ、ては、ユーザにより指定された地点 Aの地理座標（緯度および経度）が 、記録媒体 123に記録されており、地点 Aの地理座標が第 2地理情報として取得され る場合を想定する。 [0256] In this example, the geographical coordinates (latitude and longitude) of point A specified by the user are It is assumed that the geographical coordinates of point A are recorded as the second geographical information, which is recorded in the recording medium 123.
[0257] 比較部 111は、地点 Aの地理座標と、複数の第 1地理情報、つまり、各番組のロケ 地の地理座標とを比較する。  [0257] The comparison unit 111 compares the geographical coordinates of the point A with a plurality of pieces of first geographical information, that is, the geographical coordinates of the location of each program.
[0258] 地理条件番組選択部 112は、 AV出力部 105に地点 Aを表示させる（S6003)。な お、このとき、地点 Aがマップ上に表示される力 このマップは、例えば通信または記 録媒体等を介して、番組選択装置 100c内の所定の記憶領域に記憶されて!/、る。 [0258] The geographical condition program selection unit 112 displays the point A on the AV output unit 105 (S6003). At this time, the force at which the point A is displayed on the map. This map is stored in a predetermined storage area in the program selection device 100c via, for example, communication or a recording medium.
[0259] 地理条件番組選択部 112はさらに、地点 Aの地理座標と一致 (完全一致)する地理 座標を示す第 1地理情報がある場合（S6004)、その第 1地理情報に対応する番組 を選択し出力する（S6005)。 [0259] If there is first geographic information indicating the geographic coordinates that match (exactly match) the geographic coordinates of point A (S6004), the geographic condition program selection unit 112 further selects the program corresponding to the first geographic information. And output (S6005).
[0260] 具体的には、 AVデコード部 104が、当該番組の AVデータを復号し、 AV出力部 1[0260] Specifically, the AV decoding unit 104 decodes the AV data of the program, and the AV output unit 1
05が、映像と音声とを表示装置 120およびスピーカ 121に出力する。なお、このとき05 outputs the video and audio to the display device 120 and the speaker 121. At this time
、この番組を視聴するか否かをユーザに決定させてもよ!/、。 You can let the user decide whether to watch this program!
[0261] なお、 2つの位置が"完全一致"する、という場合、原則として緯度および経度等の 数値が完全に一致することを意味する。しかし、例えば数 mの違いなど、実質的に 2 つの位置の差が無視できる場合も"完全一致"に含むものとする。 [0261] When two positions are "perfectly matched", it means that the numerical values such as latitude and longitude are completely matched in principle. However, the case where the difference between two positions is negligible, such as a difference of several meters, is included in the “perfect match”.
[0262] 例えば、図 22 (A)に示すように、地点 A力 時計台"の位置であり、かつ、 "時計台" で撮影された番組が放送中である場合、表示装置 120には、この画面の表示された 後に当該番組の映像が表示される。 [0262] For example, as shown in FIG. 22 (A), when the position A force clock tower is located and the program shot at "clock tower" is being broadcast, After this screen is displayed, the video of the program is displayed.
[0263] また、地点 Aと一致する番組がない場合（S6004で No)、例えば、その旨を画像表 示または音声等でユーザに通知し、ユーザに比較精度の変更指示を促す。 [0263] If there is no program matching point A (No in S6004), for example, the fact is notified to the user by image display or sound, and the user is instructed to change the comparison accuracy.
[0264] その後、ユーザから比較精度の変更指示があった場合、具体的には、ユーザから 所定の距離等を示す情報を受け付けた場合、その情報を取得する（S6006)。 [0264] Thereafter, when there is an instruction to change the comparison accuracy from the user, specifically, when information indicating a predetermined distance or the like is received from the user, the information is acquired (S6006).
[0265] 例えば、ユーザから" 3Km"を示す情報が入力された場合、比較精度変更部 116 は、比較部 111における比較精度を、 3Km以内を許容範囲とする精度に変更する。 [0265] For example, when information indicating "3Km" is input from the user, the comparison accuracy changing unit 116 changes the comparison accuracy in the comparison unit 111 to an accuracy within an allowable range of 3Km or less.
[0266] これにより、比較部 111は、地点 Aを中心とする半径 3Km以内の地理座標は第 2地 理情報に一致 (近傍一致)すると判断する。 [0266] As a result, the comparison unit 111 determines that the geographical coordinates within the radius of 3km with the point A as the center match the second geographical information (neighbors match).
[0267] また、このとき、例えば図 22 (B)に示すように、地点 Aを中心とした半径 3Kmの円（ 点線で表されている）が表示装置 120に表示される。 [0267] At this time, for example, as shown in FIG. 22 (B), a circle with a radius of 3 km centered on the point A ( Is displayed on the display device 120).
[0268] また、当該円で示される範囲内の位置に対応する番組がある場合（S6007で Yes) 、対応する 1以上の番組の名称等を、選択可能に表示装置 120に表示する（S6008[0268] If there is a program corresponding to a position within the range indicated by the circle (Yes in S6007), the names of the corresponding one or more programs are displayed on the display device 120 in a selectable manner (S6008
)。 ).
[0269] 本例においては当該円の中に"レンガ倉庫"と表示されており、 "レンガ倉庫"で撮 影された番組が選択可能であることが示されている。  [0269] In this example, "brick warehouse" is displayed in the circle, indicating that a program shot at "brick warehouse" can be selected.
[0270] この場合、例えば、ユーザの入力デバイス 122の操作により、画面上で"レンガ倉庫[0270] In this case, for example, when the user operates the input device 122, the "brick warehouse"
"が選択される。これにより、番組選択装置 100cは当該番組を出力する。 "Is selected. Thereby, the program selection device 100c outputs the program.
[0271] または、図 22 (B)に示すように、条件（地点 Aから 3Km以内）に該当する番組が 1 つである場合、番組選択装置 100cは、図 22 (B)に示す画面の表示後、所定のタイミ ングで当該番組を出力する。 [0271] Alternatively, as shown in Fig. 22 (B), when there is one program that satisfies the condition (within 3km from point A), the program selection device 100c displays the screen shown in Fig. 22 (B). Then, the program is output at a predetermined timing.
[0272] ここで、ユーザが、例えば当該番組の視聴を希望せず、さらに範囲を拡大したい場 合、または、上記範囲（地点 Aから 3Km以内）に該当する番組がない場合（S6007 で No)、携帯端末 151の番組選択装置 100cは、ユーザの所定の範囲の指定をさら に受け付ける。 [0272] Here, for example, when the user does not want to watch the program and wants to further expand the range, or when there is no program corresponding to the above range (within 3 km from point A) (No in S6007) The program selection device 100c of the portable terminal 151 further accepts a user's designation of a predetermined range.
[0273] 例えば、ユーザから" + lKm"または" 4Km"を示す情報が入力された場合（S600 9で Yes)、比較精度変更部 116は、比較部 111における比較精度を、 4Km以内を 許容範囲とする精度に変更する。  [0273] For example, when information indicating "+ lKm" or "4Km" is input from the user (Yes in S600 9), the comparison accuracy changing unit 116 allows the comparison accuracy in the comparison unit 111 to be within 4Km. The accuracy is changed to
[0274] 図 23 (A)は、地点 Aから 4Km以内を許容範囲とする精度に変更された場合の画 面の表示例である。  [0274] Fig. 23 (A) shows a display example of the screen when the accuracy is changed to an allowable range within 4 km from point A.
[0275] このように、範囲を拡大することにより、例えば図 23 (A)に示すように、新たに" B駅 "と表示され、 "B駅"で撮影された番組が条件に該当することが判る。  [0275] In this way, by expanding the range, for example, as shown in FIG. 23 (A), a new “B station” is displayed, and the program shot at “B station” satisfies the condition. I understand.
[0276] このように、変更後の範囲に含まれる番組が複数存在する場合（S6007で Yes)、 その複数の番組の名称等を選択可能に表示する（S6008)。  Thus, when there are a plurality of programs included in the changed range (Yes in S6007), the names of the plurality of programs are displayed so as to be selectable (S6008).
[0277] この場合、番組選択装置 100cは、ユーザの入力デバイス 122の操作により選択さ れた"レンガ倉庫"および" B駅"のいずれかの番組を出力する。または、図 23 (A)に 示す画面の表示後、所定のタイミングで" B駅"の番組を出力する。  [0277] In this case, the program selection device 100c outputs the program of either "brick warehouse" or "B station" selected by the user's operation of the input device 122. Or, after the screen shown in Fig. 23 (A) is displayed, the "B station" program is output at a predetermined timing.
[0278] また、例えば、ユーザ力 レンガ倉庫"および" B駅"の番組の視聴を希望せず、さら に範囲の拡大を指定した場合、番組選択装置 100cは、当該指定をさらに受け付け [0278] Also, for example, the user does not want to watch the program "Brick Warehouse" and "B Station", and The program selection device 100c further accepts the designation when the range expansion is designated in
[0279] 例えば、ユーザから" + 2Km"または" 6Km"を示す情報が入力された場合（S600[0279] For example, when information indicating "+ 2Km" or "6Km" is input from the user (S600
9で Yes)、比較精度変更部 116は、比較部 111における比較精度を、 6Km以内を 許容範囲とする精度に変更する。 9), the comparison accuracy changing unit 116 changes the comparison accuracy in the comparison unit 111 to an accuracy within an allowable range of 6 km or less.
[0280] これにより、例えば、表示装置 120に図 23 (B)に示す画面表示がなされ、新たに" 展望台"の番組が選択可能となることが判る。ユーザは、これら 3つの中から視聴を所 望する番組を選択することで視聴することができる。 Accordingly, for example, the screen display shown in FIG. 23B is made on the display device 120, and it can be seen that a new “observation platform” program can be selected. The user can view the program by selecting the desired program from these three.
[0281] または、図 23 (B)に示す画面表示の後、所定のタイミングで"展望台"の番組を出 力する。 [0281] Alternatively, after the screen display shown in Fig. 23 (B), the "observation platform" program is output at a predetermined timing.
[0282] このように、比較精度変更部 116は、ユーザの指示に従い、比較部 111における比 較の精度を、許容範囲が拡大するように変更する。これにより、ユーザに適した番組 を効率よくユーザに提示することが可能となる。  [0282] In this way, the comparison accuracy changing unit 116 changes the comparison accuracy in the comparison unit 111 so that the allowable range is expanded in accordance with a user instruction. As a result, a program suitable for the user can be efficiently presented to the user.
[0283] なお、このような比較精度の変更ではなぐ第 2地理情報をユーザの指示に応じて 修正することでも、図 22および図 23を用いて説明した処理が実現可能である。  Note that the processing described with reference to FIG. 22 and FIG. 23 can also be realized by correcting the second geographic information, which is not a change in comparison accuracy, in accordance with a user instruction.
[0284] 例えば、地点 Aを示す地理座標が第 2地理情報として番組選択装置 100cに取得さ れ、ユーザから" 3Km"を示す情報が入力された場合を想定する。  [0284] For example, it is assumed that the geographic coordinates indicating the point A are acquired as the second geographic information by the program selection device 100c, and the information indicating "3Km" is input from the user.
[0285] この場合、第 2地理情報を、地点 Aを中心とする半径 3Km以内の範囲を示す情報 に修正する。  [0285] In this case, the second geographic information is corrected to information indicating a range within a radius of 3 km around the point A.
[0286] こうすることでも、比較精度を、 3Km以内を許容範囲とする精度に変更した場合と 同じぐ当該範囲内の番組をユーザに視聴させることが可能となる。  [0286] This also makes it possible for the user to view a program within the same range as when the comparison accuracy is changed to an accuracy within an allowable range of 3 km or less.
[0287] なお、このような処理は、実施の形態 3における番組選択装置 100bのように、第 2 地理情報を修正する機能を有していれば可能である。  [0287] Note that such processing is possible as long as it has a function of correcting the second geographic information, like the program selection device 100b in the third embodiment.
[0288] また、携帯端末 151が、実施の形態 2における携帯端末 150と同じく GPS受信装置 130を備えてもよい。  [0288] Also, the mobile terminal 151 may include the GPS receiving device 130 as in the mobile terminal 150 in the second embodiment.
[0289] この場合、番組選択装置 100cは、第 2地理情報として、番組選択時のユーザの現 在位置を GPS受信装置 130から取得することができる。  [0289] In this case, the program selection device 100c can acquire the current position of the user at the time of program selection from the GPS reception device 130 as the second geographic information.
[0290] 例えば、 GPS受信装置 130を備えた携帯端末 151を所持するユーザ力 図 22 (A )に示す"時計台"に行った場合を想定する。 [0290] For example, the ability of a user to have a mobile terminal 151 equipped with a GPS receiver 130 is shown in FIG. Suppose you go to the “clock tower” shown in ().
[0291] この場合、番組選択装置 100cは、 GPS受信装置 130を介し、当該時計台の緯度 および経度を第 2地理情報として取得する。 [0291] In this case, the program selection device 100c acquires the latitude and longitude of the clock tower as the second geographic information via the GPS reception device 130.
[0292] 従って、その時点で、当該時計台で撮影された番組を携帯端末 151が受信してい る場合、番組選択装置 100cは、当該番組を選択し出力する。 [0292] Therefore, at that time, when the portable terminal 151 receives a program shot by the clock tower, the program selection device 100c selects and outputs the program.
[0293] これにより、ユーザは、自身が存在している位置で撮影された番組を、即座に視聴 すること力 Sでさる。 [0293] Thus, the user can use the power S to immediately watch the program shot at the position where the user exists.
[0294] また、その時点で、当該時計台で撮影された番組が放送されて!/、な!/、場合、ユー ザは比較精度を変更することができる。これにより、図 22 (B)等に示すように、 自身が 現在存在して!/、る位置 Aを基準とする所定の範囲内に含まれる番組を容易に視聴す ること力 Sでさる。  [0294] At that time, if the program shot on the clock tower is broadcasted! /, N! /, The user can change the comparison accuracy. As a result, as shown in FIG. 22 (B) and the like, it is possible to easily watch a program included in a predetermined range based on the position A where it is present!
[0295] (実施の形態 5) [0295] (Embodiment 5)
本発明の実施の形態 5として、地理情報テーブルが更新される毎に、地理座標の 比較を行う場合の番組選択装置 100の動作について説明する。  As the fifth embodiment of the present invention, the operation of the program selection device 100 when comparing geographic coordinates each time the geographic information table is updated will be described.
[0296] なお、本実施の形態における番組選択装置 100の機能的な構成は、実施の形態 1 におけるものと同じである（図 1参照）。 [0296] The functional configuration of program selection apparatus 100 in the present embodiment is the same as that in Embodiment 1 (see Fig. 1).
[0297] また、第 2地理情報である地理座標も、実施の形態 1と同じぐ第 2地理情報取得部 [0297] Also, the second geographic information acquisition unit having the same geographic coordinates as the second geographic information as in the first embodiment.
109により記録媒体 123から読み出される（図 10参照）。  109 is read from the recording medium 123 (see FIG. 10).
[0298] また、図 2を用いて説明した TSを受信後にその TSに含まれる地理座標を用いて番 組地理情報テーブル 108を生成（図 9参照）し、さらに地理情報テーブルを更新する 場合について説明する。 [0298] In addition, after receiving the TS described with reference to Fig. 2, the program geographic information table 108 is generated using the geographic coordinates included in the TS (see Fig. 9), and the geographic information table is updated. explain.
[0299] 図 24は、実施の形態 5における番組選択装置 100の番組地理情報テーブル 108 の更新に伴う比較処理の流れを示すフローチャートである。 FIG. 24 is a flowchart showing the flow of comparison processing accompanying the update of the program geographic information table 108 of the program selection device 100 in the fifth embodiment.
[0300] まず、セクション解析部 103は、上述のように、 TSデコード部 102により取り出され た各番組の番組情報を番組情報記憶部 106に登録する。これにより、各番組につ!/、 ての地理座標が番組情報記憶部 106に記憶される（S 7001 )。 First, section analysis unit 103 registers the program information of each program extracted by TS decoding unit 102 in program information storage unit 106 as described above. As a result, the geographical coordinates of each program are stored in the program information storage unit 106 (S 7001).
[0301] また、第 1地理情報取得部 107は、番組情報記憶部 106に記憶されている各地理 座標を用いて、番組地理情報テーブル 108を生成する。 [0302] その後、第 1地理情報取得部 107は、番組情報記憶部 106の記憶内容を監視する 。監視中に番組地理情報テーブル 108の更新が必要となった場合（S7002で Yes) 、第 1地理情報取得部 107は、番組地理情報テーブル 108を更新する（S7003)。 [0301] In addition, the first geographic information acquisition unit 107 generates a program geographic information table 108 using each geographic coordinate stored in the program information storage unit 106. [0302] Thereafter, the first geographic information acquisition unit 107 monitors the stored contents of the program information storage unit 106. When the program geographic information table 108 needs to be updated during monitoring (Yes in S7002), the first geographic information acquisition unit 107 updates the program geographic information table 108 (S7003).
[0303] 例えば、セクション解析部 103により、同一の番組 IDについて異なる地理座標が番 組情報記憶部 106に新たに記憶された場合、第 1地理情報取得部 107は番組地理 情報テーブル 108における当該番組 IDの地理座標を、新たな地理座標に変更する [0303] For example, when the section analysis unit 103 newly stores different geographic coordinates for the same program ID in the program information storage unit 106, the first geographic information acquisition unit 107 sets the program in the program geographic information table 108. Change the geographic coordinates of the ID to the new geographic coordinates
〇 Yes
[0304] また、新たな番組情報が番組情報記憶部 106に追加登録された場合も、当該番組 の地理座標を番組地理情報テーブル 108に追加する更新を行う。  [0304] Also, when new program information is additionally registered in the program information storage unit 106, the update is performed by adding the geographic coordinates of the program to the program geographic information table 108.
[0305] 第 1地理情報取得部 107は、このように番組地理情報テーブル 108を更新すると、 更新後の番組地理情報テーブル 108の内容を比較部 111に通知する。比較部 111 は、更新後の各地理座標と、第 2地理情報に示される地理座標とを比較する（S700 4)。  [0305] When the first geographic information acquisition unit 107 updates the program geographic information table 108 in this way, the first geographic information acquisition unit 107 notifies the comparison unit 111 of the contents of the updated program geographic information table 108. The comparison unit 111 compares the updated geographic coordinates with the geographic coordinates indicated in the second geographic information (S700 4).
[0306] その後、実施の形態 1と同じぐ第 2地理情報に示される地理座標に最も近い地理 座標に対応する番組を選択し出力する（図 11参照）。  [0306] After that, the program corresponding to the geographic coordinate closest to the geographic coordinate shown in the second geographic information as in Embodiment 1 is selected and output (see FIG. 11).
[0307] また、番組地理情報テーブル 108が更新されな!/、場合（S7002で No)、番組地理 情報テーブル 108が更新されるまで、上記の監視を続ける。 [0307] If the program geographic information table 108 is not updated! / (No in S7002), the above monitoring is continued until the program geographic information table 108 is updated.
