As shown in Drawing.1, the content evaluator SYS 1  is comprised of a server unit  10  (an example of the “server unit”), and a terminal unit  20  (an example of the “terminal unit”) which a viewer or an auditor who evaluates a content operates. Although the example of Drawing 1 shows only one terminal unit  20 , multiple terminal units may be connected to the server unit  10 . 
         [0022]    The server unit  10  and the terminal unit  20  are able to mutually send and receive data through a network NW (a transmission path) using communications protocols, such as TCP/IP. Examples of the network NW are the Internet, LAN (Local Area Network), leased line network such as CATV (Community Antenna Television) circuit, a mobile communications network (a base station etc. are included), a gateway, etc. 
         [0023]      FIG. 2  shows a composition of the server unit  10 . In this example, the server unit  10  is composed of a data storage  13 , a system controller  15 , and a data sender and receiver  17 , and those components are connected and coordinated through a system bus  11 .

It sends and receives various data to and from other apparatus, such as the terminal unit  20 . 
         [0031]    [An Evaluation Routine of the Embodiment 1] 
         [0032]    With reference to Drawing 4, an evaluation routine to realize the evaluator embodiment 1 is described below. 
         [0033]    To start, the terminal unit  20  sends identification information to the server unit  10  through a data transmission path. A content information to evaluate may be sent spontaneously (Step S 1 A). Correspondingly, the server unit  10  records the received identification information on the identification information DB  131 , and processes authorization (Step S 1 B). The terminal unit  20  stands by until receiving a content from the server unit  10  (step S 2 A: NO), after sending the identification information. 
         [0034]    Next, the server unit  10  specifies a content which a viewer or an auditor evaluates based on the identification information and the content information received in the former step (step S 2 B), reads the specified content from the contents DB  132 , and sends it to the terminal unit  20  (Step S 3 B). When the terminal unit  20  receives the content (step S 2 A: YES), the terminal unit  20  presents (plays) the content (Step S 3 A). 
         [0035]    While presenting the contents, the terminal unit  20  accepts and records a primary evaluation (a simple and intuitive evaluation such as “positive” or “negative”). In other words, the primary evaluation is made by sequentially evaluating a content Specifically, for example, the terminal unit  20  displays a screen drown in the Drawing 5, and monitors a primary evaluation until an end of a content presentation. (step S 4 A: NO, step S 6 A: NO). In the screen example shown in Drawing 5, a content is displayed in a content presentation area  41 , and alternatives of evaluation are displayed in an evaluation alternatives area  43 . 
         [0036]    The primary evaluation may be conducted by touching an alternative displayed such as shown in Drawing 5 (“Very Positive”, “Relatively Positive”, “Slightly Positive”, “Slightly Negative”, “Relatively Negative”, “Very Negative”) while presenting a content, or when the accepter  27  is a keyboard, the primary evaluation action may be conducted by pushing a key associated with each alternative. In addition, it is not necessary that the primary evaluation is conducted at a viewer or an auditor&#39;s arbitrary moment. It may be conducted periodically, or conducted for each scene. 
         [0037]    When the primary evaluation action is detected (Step S 4 A: YES), the terminal unit  20  records the primary evaluation information containing time-point information (Step S 5 A). When the terminal unit  20  recognizes the end of the content (step S 6 A: YES), it sends the primary evaluation information recorded in Step S 5 A to the server unit  10  (Step S 7 A). 
         [0038]    On the other hand, the server unit  10  stands by until it receives the primary evaluation information from the terminal unit  20 , after processing of S 3 B (step S 4 B: NO). When the terminal unit  20  sends the primary evaluation information (Step S 7 A), and the server unit  10  receives the primary evaluation information (step S 4 B: YES), the server unit  10  records the received primary evaluation information on the evaluation information and content piece DB  133  (Step S 5 B), generates a content piece based on the primary evaluation information recorded, and records the information of the content piece on the evaluation information and content piece DB  133  (Step S 6 B). 
         [0039]    The content piece is a part of a content, extracted by identifying the part in accordance with the primary evaluation. One content piece may be a consecutive part of a content, or intermittent parts of a content. The content piece may be generated by, for example, extracting a part of which a starting point is a certain period of time (30 seconds, for example) before the primary evaluation action and an ending point is a certain period of time after the primary evaluation action. The certain period of time may be set arbitrarily. Another example of methods of the content piece generation is extracting a part which contains large amount of the primary evaluation of same direction (for example, “Positive”). To identify a part, primary evaluations may be converted to a numerical value. For example, “3” for “Very Positive”, “2” for “Relatively Positive”, “1” for “Slightly Positive”, “−1” for “Slightly Negative”, “−2” for “Relatively Negative” and “− 3 ” for “Very Negative”. 
         [0040]    To list more examples of methods of the content piece generation, when multiple terminal unit  20  evaluating a same content exist, the server unit  10  may identify a part to extract and generate the content piece in accordance with the primary evaluation information sent from those multiple terminal unit  20  by synthesizing or comparing the primary evaluation information from each terminal unit  20 . A content piece may be generated for each terminal unit  20 , or for all terminal unit  20 . 
         [0041]    The terminal unit  20  stands by until it receives a content piece information from the server unit  10  (step S 8 A: NO), after processing of S 7 A. The server unit  10  sends the generated content piece information after processing of S 6 B to the terminal unit  20  (step S 7 B). When the terminal unit  20  receives the content piece information (Step S 8 A: YES), it inquires a viewer or an auditor whether or not to conduct a secondary evaluation by presenting an inquiry. If a viewer or an auditor responds not to conduct (step S 9 A: NO), the terminal unit  20  ends processing according to this flow chart. 
         [0042]    If a viewer or an auditor responds to conduct the secondary evaluation (Step S 9 A: YES), a secondary evaluation mode is performed and the terminal unit  20  presents (plays) the content piece received (Step S 10 A). After processing of S 10 A, the terminal unit  20  waits for the secondary evaluation action, which is an evaluation to the content piece, and accept it (Step S 11 A). 
         [0043]    Examples of the secondary evaluation are shown in Drawing 6 and Drawing 7. The secondary evaluation may be an evaluation different and more precise from the primary evaluation, such as shown in Drawing 6 for a content piece with positive primary evaluation, and such as shown in Drawing 7 for a content piece with negative primary evaluation. 
         [0044]    In a screen example shown in Drawing 6 and Drawing 7, the content piece is presented on a content piece display area  51 , alternatives of evaluation are displayed on an evaluation alternatives area  53 , and a free comment box is displayed on a free comment area  55 . The secondary evaluation may be accepted after finishing a presentation (play) of a content (meanwhile all the primary evaluation finishes), or during a presentation (play) of a content (meanwhile the primary evaluation is continued to be accepted). Timing and length of accepting the secondary evaluation may be arbitrary. 
         [0045]    The secondary evaluation action may be conducted by touching an alternative displayed such as shown in Drawing 6 and Drawing 7, or when the accepter  27  is a keyboard, the secondary evaluation action may be conducted by pushing a key associated with each alternative. The secondary evaluation may be a free comment input into the free comment box. The secondary evaluation may overwrite the primary evaluation, such as changing from “Positive” to “Negative”. 
         [0046]    The server unit  10  stands by until it receives the secondary evaluation information from the terminal unit  20  (Step S 8 B: NO), after processing of S 7 B. The terminal unit  20  sends the secondary evaluation information to the server unit  10  (Step S 12 A), after processing of S 11 A, and ends processing according to this flow chart. The secondary evaluation information may contain time-point information. When the server unit  10  receives the secondary evaluation information (Step S 8 B: YES), it associates the secondary evaluation information to the content piece, and records on the evaluation information and content pieces DB  133  (step S 212 B), and ends processing according to this flow chart. 
         [0047]    The embodiment 1 is the evaluator, the evaluation system, and embodiment 1 is composed of the server unit and the terminal unit.

         [0049]    Components to process S 6 B (generate a content piece) correspond to the content piece extractor. 
         [0050]    Components to process S 10 A (present a content piece) correspond to the content piece presenter. 
         [0051]    Components to process S 11 A (accept a secondary evaluation for the content piece) correspond to the secondary evaluation acceptor. 
         [0052]    Embodiment 1 as an evaluation system, components to process S 4 A (detected a primary evaluation action?), S 5 A (record the primary evaluation information) correspond to the primary evaluation accepter. 
         [0053]    Components to process S 7 A (send the primary evaluation information) correspond to the primary evaluation information sender. 
         [0054]    Components to process S 4 B (received the primary evaluation information?) correspond to the primary evaluation information receiver. 
         [0055]    Components to process S 6 B (generate a content piece) correspond to the content piece extractor. 
         [0056]    Components to process S 7 B (send a content piece information) correspond to the content piece sender. 
         [0057]    Components to process S 8 A (received a content piece information?) correspond to the content piece receiver. 
         [0058]    Components to process S 11 A (accept the secondary evaluation for the content piece) correspond to the secondary evaluation acceptor. 
         [0059]    Components to process S 12 A (send the secondary evaluation information) correspond to the secondary evaluation information sender. 
         [0060]    Components to process S 9 B (received the secondary evaluation information?) correspond to the secondary evaluation information receiver. 
         [0061]    Embodiment 1 as a server unit, components to process S 4 B (received the primary evaluation information?) and S 5 B (Record the primary evaluation information) correspond to the primary evaluation information receiver. 
         [0062]    Components to process S 6 B (generate a content piece) correspond to the content piece extractor. 
         [0063]    Components to process S 7 B (send a content piece information) correspond to the content piece sender. 
         [0064]    Components to process S 9 B (received the secondary evaluation information?) correspond to the secondary evaluation information receiver. 
         [0065]    Embodiment 1 as a terminal unit, components to process S 4 A (detected a primary evaluation action?), S 5 A (record the primary evaluation information) correspond to the primary evaluation accepter. 
         [0066]    Components to process S 7 A (send the primary evaluation information) correspond to the primary evaluation information sender. 
         [0067]    Components to process S 8 A (received a content piece information?) correspond to the content piece receiver. 
         [0068]    Components to process S 11 A (accept the secondary evaluation for the content pieces) correspond to the secondary evaluation acceptor. 
         [0069]    In step S 4 A-S 7 A, while the embodiment 1 sends the primary evaluation information collectively after an end of presentation of a content, the primary evaluation information may be sent to the server unit  10  one by one, when the primary evaluation action is detected. 
         [0070]    In step S 7 B and S 8 A, while in the case of the embodiment 1, the content piece information includes the content piece itself, the content piece information may include only time-point information and information to identify a content, and may not include the content piece itself. In this case, the content piece may be generated in the terminal unit  20 . 
         [0071]    The evaluator, the evaluation system, the server unit and the terminal unit of the embodiment 1 enables to conduct simple and intuitive primary evaluations while viewing a live performance or a recorded content, and enables to conduct the secondary evaluation which is different and more precise from the primary evaluation. In other expression, by extracting the content pieces according to the primary evaluation, and by accepting re-evaluation to the content pieces, a viewer or an auditor can precisely evaluate a content. 
         [0072]    The information saved in the identification information DB  131 , in the contents DB 132 , in the evaluation information and content pieces DB 133 , can be accessed from arbitrary terminal devices. This enables a creator of a content to view the primary evaluation and the secondary evaluation, and revise the content accordingly, for example. 
         [0073]    Furthermore, the terminal unit  20  may process all the above-mentioned routines. That is, a content is preliminarily saved in the terminal unit  20  and the terminal unit  20  presents (plays) the content (step S 3 A), accepts the primary evaluation (step S 4 A-S 6 A), generates the content piece in accordance with the primary evaluation (step S 6 B), presents the content piece (Step S 10 A), and accepts the secondary evaluation (Step S 11 A). 
         [0074]    In this case, the terminal unit  20  accepts and records the primary evaluation through processing step S 4 A, S 6 A, S 7 A, S 4 B, S 5 B, and this corresponds to a primary evaluation accepter. 
         [0075]    The terminal unit  20  specifies a part of a content to extract in accordance with the primary evaluation, and generates the content piece through processing S 6 B. This corresponds to a content piece extractor. 
         [0076]    The terminal unit  20  presents the content piece through processing S 7 B, S 8 A, S 10 A. This corresponds to a content piece presenter. 
         [0077]    The terminal unit  20  accepts the secondary evaluation through processing S 10 A, S 11 A, S 8 B, S 9 B. This corresponds to a secondary evaluation acceptor. 
         [0078]    In addition, position information obtained by GPS etc. may be included in the primary evaluation information and the secondary evaluation information. The position information may be included as metadata of the primary evaluation information and the secondary evaluation information, and the position information concerned itself may serve as the primary evaluation or the secondary evaluation. For example, the primary evaluation and the secondary evaluation may be conducted by detecting a place an evaluation is conducted, or a place an evaluation is sent. 
       The Embodiment 2 
       [0079]    A content evaluator including a server unit and a terminal unit of the embodiment 2 of the present invention is described in the following sentences while referring to the attached drawings.  FIG. 8  shows a content evaluator SYS 2  which is the embodiment 2 of the present invention. As shown in Drawing.8, the content evaluator SYS 2  is comprised of a server unit  10  (an example of the “server unit”), and a terminal unit  20  (an example of the “terminal unit”) which a viewer or an auditor who evaluates a content operates, and a content recorder  60 . Although the example of Drawing 8 shows only one terminal unit  20 , multiple terminal units may be connected to the server unit  10 . 
         [0080]    The server unit  10 , the terminal unit  20  and the content recorder  60  are able to mutually send and receive data through a network NW (a transmission path) using communications protocols, such as TCP/IP. Examples of the network NW are the Internet, LAN (Local Area Network), leased line network such as CATV (Community Antenna Television) circuit, a mobile communications network (a base station etc. are included), a gateway, etc. 
         [0081]    The server unit  10  and the terminal unit  20  have the same composition as the server unit  10  and the terminal unit  20  of the embodiment 1. The content recorder  60  is a terminal unit which has a function to record at least one of an image of the content and a sound of the content, and the content recorder  60  has a function to send a recorded information through the network NW. The content recorder  60  may be a smart phone, a personal computer (PC), a tablet PC, a feature phone, and a PDA (Personal Digital Assistant) etc. with a recording function. 
       [An Evaluation Routine of the Embodiment 2] 
       [0082]    With reference to Drawing 9, an evaluation routine to realize the evaluator embodiment 2 is described below. 
         [0083]    To start, the terminal unit  20  sends identification information to the server unit  10  through a data transmission path. A content information of a live performance to evaluate may be sent spontaneously (Step S 21 A). Meanwhile, the content recorder  60  sends identification information to the server unit  10  through the data transmission path. A content information of a live performance to record may be sent spontaneously (Step S 21 C). Correspondingly, the server unit  10  records the received identification information on the identification information DB  131 , and processes authorization (Step S 21 B). 
         [0084]    The terminal unit  20  stands by until detecting a signal of start of the primary evaluation from the server unit  10  (step S 22 A: NO), after S 21 A. Meanwhile, the content recorder  60  stands by until detecting a start recording action to the content recorder  60  (step S 22 C: NO), after S 21 A. 
         [0085]    When the content recorder  60  detected the start recording action (step S 22 C: YES), the content recorder  60  sends a signal of the start of recording to the server unit  10 , and starts recording a live performance (Step S 23 C). The signal of the start of recording includes time-point information, and may include other information. 
         [0086]    When the server unit  10  received a signal of start of recording (step S 22 B: YES), the server unit  10  sends a signal of start of the primary evaluation to the terminal unit  20  (Step S 23 B). When the terminal unit  20  received the signal of start of the primary evaluation (step S 22 A: YES), the terminal unit  20  stars accepting the primary evaluation (Step S 23 A). 
         [0087]    On the other hand, the content recorder  60  stands by until it detects an end recording action (step S 24 C: NO), after processing of S 23 C. The server unit  10  stands by until it detect a signal of an end of recording and the recorded content sent from the content recorder  60 , after processing of Step S 23 B (step S 24  B:NO). When the content recorder  60  detected an end recording action (step S 24 C: YES), the content recorder  60  ends the recording, and send a signal of an end of the recording, and the recorded content, to the server unit  10  (Step S 25 C), and ends processing according to this flow chart. When the server unit  10  received a signal of an end of the recording, and the content recorded, from the content recorder  60  (step S 24 B: YES), it sends a signal of an end of the primary evaluation (Step S 25 B), and records the recorded content on the contents DB  132  (Step S 26 B). 
         [0088]    The terminal unit  20  accepts and records the primary evaluation, as same as the routine  1  the embodiment 1. Specifically, the terminal unit  20  displays a screen drown in the Drawing 5, and monitors the primary evaluation until an end of a content presentation. (step S 24 A: NO, step S 26 A: NO). In the case of the embodiment 2, the primary evaluation may be sequential evaluation to the live performance ongoing. In the case of the embodiment 2, content presentation area  41  may exist, or may not exist. When exist, content presentation area may present s live streaming movie etc. In addition, it is not necessary that the primary evaluation is conducted at a viewer or an auditor&#39;s arbitrary moment. It may be conducted periodically, or conducted for each scene. 
         [0089]    The primary evaluation may be conducted by touching an alternative displayed such as shown in Drawing 5 (“Very Positive”, “Relatively Positive”, “Slightly Positive”, “Slightly Negative”, “Relatively Negative”, “Very Negative”), or when the accepter  27  is a keyboard, the primary evaluation action may be conducted by pushing a key associated with each alternative. 
         [0090]    When the primary evaluation action is detected (Step S 24 A: YES), the terminal unit  20  records the primary evaluation information containing time-point information (Step S 25 A). When the terminal unit  20  received a signal of an end of the content (step S 26 A: YES), it sends the primary evaluation information recorded in Step S 25 A to the server unit  10  (Step S 27 A). 
         [0091]    The server unit  10  stands by until it receives the primary evaluation information from the terminal unit  20 , after processing of S 26 B (step S 27 B: NO). When the server unit  10  received the primary evaluation information (step S 27 B: YES), the server unit  10  records the received primary evaluation information on the evaluation information and content piece DB  133  (step S 28 B). 
         [0092]    The server unit  10  generates a content piece based on the primary evaluation information recorded, and records the information of the content piece on the evaluation information and content piece DB  133  (Step S 29 B), after processing of S 28 B. 
         [0093]    The content piece is a part of the content of the live performance recording, extracted by identifying the part in accordance with the primary evaluation. One content piece may be a consecutive part of a content, or intermittent parts of a content. The content piece may be generated by, for example, extracting a part of which a starting point is a certain period of time (30 seconds, for example) before the primary evaluation action and an ending point is a certain period of time after the primary evaluation action. The certain period of time may be set arbitrarily. Another example of methods of the content piece generation is preliminarily dividing the live performance or the recorded content into several sections, and extracting a section which contains large amount of the primary evaluation of same direction (for example, “Positive”). 
         [0094]    To list more examples of methods of the content piece generation, when multiple terminal unit  20  evaluating a same content lively performed exist, the server unit  10  may identify a part to extract and generate the content piece in accordance with the primary evaluation information sent from those multiple terminal unit  20  by synthesizing or comparing the primary evaluation information from each terminal unit  20 . A content piece may be generated for each terminal unit  20 , or for all terminal unit  20 . 
         [0095]    The terminal unit  20  stands by until it detects a content piece information from the server unit  10  (step S 28 A: NO), after processing of S 27 A. The server unit  10  sends the generated content piece information after processing of S 29 B to the terminal unit  20  (step S 210 B). When the terminal unit  20  detects the content piece information (Step S 28 A: YES), it inquires a viewer or an auditor whether or not to conduct a secondary evaluation by presenting an inquiry. If a viewer or an auditor responds not to conduct (step S 29 A: NO), the terminal unit  20  ends processing according to this flow chart. 
         [0096]    If a viewer or an auditor responds to conduct the secondary evaluation (Step S 29 A: YES), a secondary evaluation mode is performed and the terminal unit  20  presents (plays) the content piece received (Step S 210 A). After processing of S 210 A, the terminal unit  20  waits for the secondary evaluation action, which is an evaluation to the content piece, and accept it (Step S 211 A). 
         [0097]    In the same manner as the embodiment 1, the secondary evaluation may be an evaluation different and more precise from the primary evaluation, such as shown in Drawing 6 for a content piece with positive primary evaluation, and such as shown in Drawing 7 for a content piece with negative primary evaluation. 
         [0098]    In the same manner as the embodiment 1, the secondary evaluation action may be conducted by touching an alternative displayed such as shown in Drawing 6 and Drawing 7, or when the accepter  27  is a keyboard, the secondary evaluation action may be conducted by pushing a key associated with each alternative. The secondary evaluation may be a free comment input into the free comment box. 
         [0099]    The server unit  10  stands by until it receives the secondary evaluation information from the terminal unit  20  (Step S 211 B: NO), after processing of Step S 210 B. The terminal unit  20  sends the secondary evaluation information to the server unit  10  (Step S 212 A), after processing of Step S 211 A, and ends processing according to this flow chart. The secondary evaluation information may contain time-point information. When the server unit  10  receives the secondary evaluation information (Step S 211 B: YES), it associates the secondary evaluation information to the content piece, and records on the evaluation information and content pieces DB  133  (step S 212 B), and ends processing according to this flow chart. 
         [0100]    The evaluator, the evaluation system, the server unit and the terminal unit of the embodiment 1 enables to conduct simple and intuitive primary evaluations while viewing a live performance or a recorded content, and enables to conduct the secondary evaluation which is different and more precise from the primary evaluation. In other expression, by extracting the content pieces according to the primary evaluation, and by accepting re-evaluation to the content pieces, a viewer or an auditor can precisely evaluate a live performance or a recorded content. 
         [0101]    The information saved in the identification information DB  131 , in the contents DB 132 , in the evaluation information and content pieces DB 133 , can be accessed from arbitrary terminal devices. This enables a live performer to view the primary evaluation and the secondary evaluation, and improve the live performance accordingly, for example. 
         [0102]    Furthermore, when the content recorder  60  is equipped with an output function such as image output or an audio output, for example a PC or a smart phone, or a tablet PC etc., the server unit  10  may send the primary evaluation information and the secondary evaluation information to the content recorder, after detecting the secondary evaluation information (step S 211 B). This case enables a live performer staying in the same place as the content recorder  60  to see the primary evaluation and the secondary evaluation, without accessing the server unit  10  from another terminal unit. 
         [0103]    Furthermore, when the content recorder  60  is equipped with an input function, for example a PC or a smart phone, or a tablet PC etc., the content recorder  60  may process S 28 A-S 212 A. In the other expression, the content recorder  60  may accept the secondary evaluation. This case enables a live performer to hear an evaluation while a viewer or an auditor conducted the primary evaluation is inputting the secondary evaluation. 
         [0104]    In step S 210 B and S 28 A, while in the case of the embodiment 1, the content piece information includes the content piece itself, the content piece information may include only time-point information and information to identify a content, and may not include the content piece itself. In this case, the terminal unit  20  obtain and record the content on itself before S 28 A, and the content piece may be generated in the terminal unit  20 . And in the case the content recorder process S 28 A-S 212  as mentioned above, the content recorder  60  may receive the content piece information including time-point information to identify the content piece, and the content recorder  60  may generate the content piece. 
         [0105]    In addition, position information obtained by GPS, by detecting the place the primary evaluation or the secondary evaluation conducted etc., may be included in the primary evaluation information and the secondary evaluation information. The position information may be included as metadata of the primary evaluation information and the secondary evaluation information, and the position information concerned itself may serve as the primary evaluation or the secondary evaluation. For example, the primary evaluation and the secondary evaluation may be conducted by detecting a place an evaluation is conducted, or a place an evaluation is sent. Utilization of GPS information may serve to improve the quality of an evaluation. For example, utilization of GPS enables to exclude the primary evaluation conducted in the place apart from the place a live performance conducted. 
         [0106]    The content recorder  60  may process all the above-mentioned routines. That is, records at least one of an image of the content and a sound of the content (step S 22 C-S 25 C), accepts the primary evaluation (step S 23 A-S 26 A), generates the content piece in accordance with the primary evaluation (step S 29 B), presents the content piece (Step S 210 A), and accepts the secondary evaluation (step S 211 A). 
         [0107]    The embodiment 2 is the evaluator, the evaluation system, and embodiment 1 is composed of the server unit and the terminal unit.

         [0130]    [Input Methods of the Primary Evaluation and the Secondary Evaluation] 
         [0131]    While some examples of input methods are described in the above-mentioned embodiments, an input method of the primary evaluation and the secondary evaluation is not restricted to those described in the above-mentioned embodiments. For example, an input method of the primary evaluation may be scrolling a wheel equipped in a mouse when using a mouse as the input component, or tapping, flipping and swiping when using a touch panel as the input component. A controller equipped with a three-axis gyroscope or an acceleration sensor is another example of an input method. In this case, inclining, shaking and waiving are examples of an input action, and the evaluation content is determined by referring to a sensor information such as a gradient, direction, speed and size of waiving, a number of shaking etc. A camera is another example of an input method. In this case, motion gesture captured by an image recognition may be an input action. A audio input device is another example of an input method. In this case, volume, pitch, and tone of sound or voice may be used to determine an evaluation content. Furthermore, in case of audio input, voice recognition may be used to determine an evaluation content. 
         [0132]    [Form of the Primary Evaluation] 
         [0133]    While some examples of forms are described in the above-mentioned embodiments, a form of the primary evaluation is not restricted to those described in the above-mentioned embodiments. For example, a form of the primary evaluation may be simply inputting a point score, or selecting from alternatives such as shown in the secondary evaluation. Furthermore, a viewer or an auditor may indicate a willingness to conduct the secondary evaluation to a certain point of a content, so that the content extractor generates the content piece which include the certain point (for example, the content piece of which a starting point is a certain period of time before the point the indication is made and an ending point is a certain period of time after the point the indication is made). 
         [0134]    [A Generation Method of the Content Piece] 
         [0135]    While some examples of methods of generating the content piece are described in the above-mentioned embodiments, a method of generating the content piece is not restricted to those described in the above-mentioned embodiments. For example, the content extractor may generate the content piece in accordance with the degree of difference in the primary evaluations between multiple terminal units  20 . Another example is that the content extractor may generate the content piece in accordance with the degree of difference between a predicted evaluation which is preliminarily input, and an actual evaluation (one example is a part of a content predicted to be evaluated “positive”, and actually evaluated “negative”. Another example is a part large amount of the primary evaluation predicted, and actually no primary evaluation conducted). 
         [0136]    The content piece may be generated by preliminarily dividing a content into a plurality of sections, and selecting one a plurality of sections. The content piece may comprise at least one of a still picture of a moment of a content or a sound. The terminal unit  20  applying the described case enables a viewer or an auditor to smoothly conduct the secondary evaluation, when the network NW connection between the server unit  10  and the terminal unit  20  is inferior, or capability of the terminal unit  20  to process movie is low. 
         [0137]    [Form of the Secondary Evaluation] 
         [0138]    While some examples of forms are described in the above-mentioned embodiments, a form of the secondary evaluation is not restricted to those described in the above-mentioned embodiments. For example, a form of the secondary evaluation may be a graduated assessment for each criteria such as “eloquent”, “persuasive” etc. Another example of a form of the secondary evaluation may be providing a model case to compare to the content piece actually extracted. In addition, although a form of the primary evaluation and a form of the secondary evaluation are different in the above-mentioned embodiments, a form of the primary evaluation and a form of the secondary evaluation may be the same. 
         [0139]    While the server unit  10  generated the content piece in the above-mentioned embodiments, the terminal unit  20  may generate the content piece. In this case, the terminal unit  20  may send the primary evaluation together with the secondary evaluation to the server unit  20  when the secondary evaluation completed. 
         [0140]    While the primary evaluation includes a time-point information in the above-mentioned embodiments, the primary evaluation may not include specifically a time-point information. For example, when a content is preliminarily divided into a plurality of sections, the primary information may only include an information of a section presented at a moment the primary evaluation is made. 
         [0141]    When a content to evaluate is an audio content, the content presentation area  41  in Drawing 5 may not exist. When the content piece to evaluate is an audio content piece, the content piece presentation area  51  in Drawing 6 and Drawing 7 may not exist. 
         [0142]    All the above-mentioned terminal unit, the server composition, the routine, the form of output and input are just examples, and arbitrarily selected or changed in accordance with a use application. For example, each step in a routine may be processed at an any unit. 
         [0143]    Note that, this invention is not limited to the above-mentioned embodiments. Although it is to those skilled in the art, the following are disclosed as the one embodiment of this invention.
       Mutually substitutable members, configurations, etc. disclosed in the embodiment can be used with their combination altered appropriately.   Although not disclosed in the embodiment, members, configurations, etc. that belong to the known technology and can be substituted with the members, the configurations, etc. disclosed in the embodiment can be appropriately substituted or are used by altering their combination.   Although not disclosed in the embodiment, members, configurations, etc. that those skilled in the art can consider as substitutions of the members, the configurations, etc. disclosed in the embodiment are substituted with the above mentioned appropriately or are used by altering its combination.       
 
         [0147]    While the invention has been particularly shown and described with respect to preferred embodiments thereof, it should be understood by those skilled in the art that the foregoing and other changes in form and detail may be made therein without departing from the sprit and scope of the invention as defined in the appended claims.
