Description

  The present invention relates to an information providing system that distributes information stored in an information providing server in advance to a request source terminal in response to a request from the terminal.

  Conventionally, for example, as a part of corporate IR (Investor Relations) activities, a site dedicated to IR activities has been established on the Internet homepage, and information on IR activities has been provided using still images and moving images. (For example, see Patent Document 1).

  In particular, since the high-speed Internet environment has been dramatically improved by the spread of ADSL and optical fiber communication in recent years, provision of IR activity information using moving image data with sound has been realized on the Internet.

  As a method of providing IR activity information using such moving image data with sound, for example, a lecture form in which a director of a company appears on a browser screen of an Internet terminal and explains IR activities, and two directors and an interviewer. Appears on the browser screen, and there is an interview format in which directors respond to questions regarding IR activities from interviewers.

  In the case of a lecture format, it is easy to explain unilaterally, and it is difficult to create content so that the contents of IR activity information can be easily explained. On the other hand, in the case of an interview format, since it takes the form of an answer to a question, it is easy to create content so that the contents of IR activity information can be transmitted in an easy-to-understand manner.

  Therefore, the data size of the streaming playback video data can be made smaller than when the streaming playback video is displayed in a single display frame. Also, playback video data after downloading and playback still image data after downloading have a smaller data size and less computation required for playback than streaming playback video data, so they can be downloaded and displayed quickly. be able to.

  Therefore, any one of the reproduced moving image data after the download and the reproduced still image data after the download can be appropriately displayed on the display unit in conjunction with the streaming reproduced moving image data. As a result, the data size of the entire data received by the terminal from the information providing server can be reduced, the network load can be suppressed, and a comfortable communication environment can be maintained.

  In addition, by displaying the first display frame and the second display frame on the display unit and displaying at least one of the playback video data after the download and the playback still image data after the download on the second display frame, for example, three displays The display space can be saved rather than displaying the streaming playback video data, the playback video data after the download is completed, and the playback still image data after the download is completed. The display of the post-playback video data and the post-download still picture data after the download can be enlarged.

  According to the third aspect of the present invention, the first database of the information providing server stores the moving image data of the respondent answering the preset question and the audio data thereof, and the second database includes The video data and voice data of the questioner who asks the question are stored, and the playback means of the terminal performs the second display while playing back the video data and the voice data of the respondent in the first display frame. The moving image data obtained by photographing the questioner in the frame and the audio data thereof are reproduced.

  Usually, since the questioner's question is short and the answerer's answer is long, the video data taken by the questioner is assigned to the playback video data after the download is completed, and the video data taken by the respondent is assigned to the streaming playback video data.

  Accordingly, the questioner and the answerer are displayed side by side on the display unit of the terminal, and the questioner asks the answerer, and a virtual interview in which the answerer answers the question can be established. As a result, it is possible to provide interview-type content in which a questioner and an answerer appear with data having a smaller data size.

  According to the fourth aspect of the present invention, the first database of the information providing server stores the moving image data of the respondent answering the preset question and the audio data thereof, and the second database includes The video data of the questioner who asks the question and the audio data thereof are stored, and the third database stores still image data constituting the chart used by the respondent for the answer. While reproducing the video data of the respondent and its audio data in the first display frame, either the video data of the questioner, the audio data, or the still image data constituting the chart is displayed in the second display frame. Are appropriately displayed at a predetermined timing.

  Usually, since the questioner's question is short and the answerer's answer is long, the moving image data obtained by photographing the questioner is assigned to the reproduced moving image data after the download is completed, and the moving image data obtained by photographing the answerer is assigned to the streaming reproduced moving image data. Also, since the data size of still image data such as charts and the like used for explanation by the respondent is small, it is assigned to the reproduced moving image data after the download is completed.

  Accordingly, the questioner and the answerer are displayed side by side on the display unit of the terminal, and the questioner asks the answerer, and a virtual interview in which the answerer answers the question can be established. As a result, it is possible to provide interview-type content in which a questioner and an answerer appear with data having a smaller data size. Then, by displaying the still image data constituting the chart on the second display frame at a predetermined timing, it is possible to reinforce the explanation of the respondent and provide a more easily understandable answer.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall configuration diagram showing the present embodiment, and FIGS. 2 and 3 are diagrams for explaining screens displayed on the Internet terminal 20.

  The information providing system 1 is mainly composed of an information providing server 10 and an Internet terminal 20, and is connected to each other using the Internet (network) 2 so as to be capable of bidirectional communication.

  The information providing server 10 is a so-called Internet server that distributes predetermined data to the requesting Internet terminal 20 in response to a request from the Internet terminal 20. The information providing server 10 stores homepage data for displaying, for example, a site dedicated to IR activities of company A on the Internet terminal 20. This homepage data is described using a markup language such as HTML or XML.

  The Internet terminal 20 includes hardware such as calculation means, control means, storage means, input means such as a keyboard and a mouse, output means such as a display unit 21 and a speaker, and communication means that can connect to the Internet 2 and access the Internet server 10. Has resources. Computer software such as browser software for displaying home page data distributed from the information providing server 10 on the display unit 21 and media data reproduction software for reproducing media data composed of moving image data, audio data thereof, and still image data. Installed in an executable form.

  Typical examples of the Internet terminal 20 include a PC (personal computer) and a mobile phone (browser phone) connected to the Internet 2 via a public telephone line or the like. The URL of the information providing server 10 is input to the browser screen displayed on the display unit 21 of the Internet terminal 20 so that the information providing server 10 can be accessed and a site dedicated to the IR activity of the company A can be displayed. Has been.

  The information providing server 10 has an IR activity information storage means configured therein, and has a first database 11 storing therein relatively large moving image data and audio data, and a data size such as a flash moving image, for example. It has a second database 12 that stores relatively small moving image data and its audio data, and a third database 13 that stores still image data.

  In the first database 11, streaming playback video data 24 taken from the front of a director (respondent) of Company A who answers a prepared question and its audio data can be read out separately for each answer. Stored in the form.

  In addition, the second database 12 can read the reproduced moving image data 25 and the audio data thereof after the completion of downloading, which is taken from the front of an interviewer (questioner) who asks a question prepared in advance. Stored in a form associated with the answer.

  Then, in the third database 13, the still image data 26 reproduced after downloading, such as a chart used by the director of company A for each answer, can be read out separately for each answer and associated with each answer. Stored.

  The moving image data 24 and 25 and their audio data and still image data 26 are stored in each database in a form compressed by a known digital compression technique.

  Further, the information providing server 10 receives a request from the Internet terminal 20, and transmits / receives media data of IR activity information corresponding to the request to the requesting Internet terminal 20, and responds to an instruction from the transmitting / receiving unit 14. By executing a pre-registered program, the corresponding moving image data 24, 25, audio data, and still image data 26 are extracted from the first to third databases 11, 12, 13, and these data are combined. It has data processing means 15 that creates media data of IR activity information and supplies it to the transmitting / receiving means 14.

  The transmission / reception means 14 is configured to perform streaming distribution in which the streaming reproduction moving image data 24 and the audio data stored in the first database 11 among the media data are reproduced while being received by the Internet terminal for each packet. ing. Of the media data, one or a plurality of pre-downloaded playback video data 25 and its audio data and post-download playback still image data 26 stored in the second database 12 and the third database 13 are stored in advance. The file is downloaded to the Internet terminal 20 as a file, and download distribution is performed to reproduce the file at a predetermined timing after the download is completed.

  In the present embodiment, the first to third databases 11, 12, 13, the transmission / reception means 14, and the data processing means 15 are configured in one information providing server 10, and data communication is possible with the data bus 16. However, it is not necessary to physically provide all the components in one server. For example, the components may be shared by a plurality of servers connected to the network.

  When the Internet terminal 20 receives distribution of the media data from the transmission / reception means 14, the Internet terminal 20 executes a process of displaying the media data on the display unit 21 by the media data reproduction software. The media data reproduction software performs processing for displaying the first display frame 22 and the second display frame 23 side by side on the display unit 21 of the Internet terminal 20.

  Then, the streaming reproduction moving image data 24 extracted from the first database 11 and distributed by streaming is displayed on the first display frame 22 and the audio data is reproduced. Further, the post-downloading playback video data 25 and the post-downloading playback still image data 26 extracted from the second database 12 and the third database 13 and distributed by download are displayed on the second display frame 23 at a predetermined timing and downloaded. After completion, a process for reproducing audio data corresponding to the reproduced moving image data 25 is performed.

  In the present embodiment, as shown in FIGS. 2 and 3, the media data playback software displays the first display frame 22 on the left side of the display unit 21 of the Internet terminal 20 and the second display on the right side of the display unit 21. A frame 23 is displayed, and the first display frame 22 and the second display frame 23 are displayed in substantially the same size.

  Next, an information providing method using the information providing system 1 having the above configuration will be described below.

  First, the information providing server 10 distributes homepage data of a site dedicated to IR activities to the requesting Internet terminal 20 in response to access from the Internet terminal 20 by operations of shareholders, investors, and the like.

  The Internet terminal 20 receives the distribution from the information providing server 10 and displays a site dedicated to IR activities on the display unit 21 by browser software (not shown). On the site dedicated to IR activities displayed on the display unit 21, a plurality of questions are listed in advance, and arbitrary questions can be selected.

  When an arbitrary question item is selected on the Internet terminal 20, the request is transmitted from the Internet terminal 20 to the information providing server 10 and received by the transmission / reception means 14 of the information providing server 10.

  When the transmission / reception unit 14 of the information providing server 10 receives a request from the Internet terminal 20, the transmission / reception unit 14 instructs the data processing unit 15 to create media data corresponding to the request.

  When the data processing means 15 receives an instruction from the transmission / reception means 14, the data processing means 15 executes a pre-registered program to store the moving image data 24 and 25 stored in advance corresponding to the question items selected by the Internet terminal 20, and Audio data and still image data 26 are extracted from the first database 11, the second database 12, and the third database 13, respectively. As a result, the streaming reproduction moving image data 24 taken by the director who answers the question selected by the Internet terminal 20 and the audio data thereof are extracted from the first database 11, and the second database 12 extracts the Internet terminal. After the download is completed, an interviewer inquiring about the question item selected at 20 is captured, and the reproduced moving image data 25 and its audio data are extracted. Further, from the third database 13, reproduced still image data 26 is extracted after downloading, such as a chart used when a director answers the question.

  When the data processing means 15 extracts the corresponding moving image data 24 and 25 and their audio data and still image data 26 from the respective databases 12, 13 and 14, each data is displayed on the display unit 21 of the Internet terminal 20 in an interview format. Assembled and delivered to the transmitting / receiving means 14.

  Upon receiving each data from the data processing unit 15, the transmission / reception unit 14 converts the data into a packet and distributes it to the requesting Internet terminal 20 via the Internet 2.

  Here, the streaming reproduction moving image data 24 extracted from the first database 11 and the audio data thereof are stream-distributed, and the downloaded reproduction moving image data 25 extracted from the second database 12 and the audio data thereof are extracted from the third database 13. The extracted still image data 26 after download is downloaded and distributed as one or a plurality of data files.

  On the other hand, the Internet terminal 20 is in a state where the media data playback software is activated by clicking on an arbitrary question displayed on the site as described above, and waits for delivery from the information providing server 10.

  When the Internet terminal 20 starts receiving the streaming playback moving image data 25 extracted from the first database 11 and the packet of the audio data into the buffer by streaming delivery by the information providing server 10, the synchronous playback attached to each packet is performed. The header is checked, and the data is extracted from the buffer according to the decoding timing and decoded. Then, the compressed data is decompressed and the reproduction process is started.

  The streaming playback moving image data 24 is displayed in the first display frame 22, but the first display frame 22 is set to the right half size of the display unit 21, so that it is more than the case where it is displayed on the entire display unit 21. The data size can be reduced. Therefore, the time required for data reception can be shortened, and the burden on the Internet 2 can be reduced.

  In addition, the Internet terminal 20 receives the download distribution of the playback video data 25 after the download extracted from the second database 12 and its audio data and the still image data 26 after the download extracted from the third database, and the download is completed. A process of decompressing and reproducing at a predetermined timing is performed later. Since the data 25 and 26 stored in the second database 12 and the third database 13 have a relatively small data size, they can be downloaded in a shorter time than the streaming playback video data 24 of the first database 11. In addition, since the calculation amount associated with the reproduction is small, it can be reproduced quickly on the Internet terminal 20.

  Accordingly, linked to the streaming playback video data 24 displayed in the first display frame 22, and the playback video data 25 is displayed in the second display frame 23 after downloading at a predetermined timing, and the audio data is played back. Instead of the reproduced moving image data 25 after the download, the reproduced still image data 26 after the download can be displayed.

  Various methods can be used to link the first display frame 22 and the second display frame 23. In the present embodiment, streaming playback displayed on the first display frame 22 by data processing by the data processing means 15 is used. A method of embedding a trigger code in the moving image data 24, displaying the reproduced moving image data 25 or the still image data 26 after the download ends in the second display frame 23 based on the trigger code, and reproducing the audio data is adopted. .

  By the information processing by the media data reproduction software, the director of company A is displayed in the first display frame 22 and the interviewer is displayed in the second display frame 23 on the display unit 21 of the Internet terminal 20. Then, the moving picture asked by the interviewer is displayed in the second display frame 23, and the audio data is reproduced. Thereby, on the display part 21 of the internet terminal 20, it can be shown that the interviewer is asking a question to the director of company A, and what is called a virtual interview can be established.

  Next, a moving image answered by the director is displayed in the first display frame 22, and the audio data is reproduced. Therefore, it can appear that the director of Company A is answering the interviewer's questions. And according to the progress of the reply by the director of company A, the corresponding chart is displayed in the second display frame 23 in place of the questioner. Therefore, the Internet terminal 20 that is the request source can refer to the chart, reinforce the explanation of the director of the company A, and explain it more clearly.

  Then, the playback video data 25 and the audio data thereof are played back after the end of download, which is asked by the interviewer to the second display frame 23 at a predetermined timing. On the other hand, the streaming reproduction moving image data 24 answered by the director of the company A is displayed in the first display frame 22 and the audio data is reproduced. Therefore, the director and interviewer of Company A can appear at the same time, and it seems that they are explaining IR activities in an interview format.

  In this case, in fact, the shooting of the director of Company A and the shooting of the interviewer are performed separately, and it is possible to shoot at any time without being affected by both schedules as in the past. . Moreover, it is sufficient to prepare a camera for shooting and a microphone for voice, and it can be implemented with a small-scale facility. Also, the contents of the IR activity information can be made into an interview format so that the contents can be transmitted in an easy-to-understand manner, and the contents can be easily created.

  According to the information providing system 1 having the above configuration, the first display frame 22 and the second display frame 23 are displayed side by side on the display unit 21 of the Internet terminal 20, and among the first display frame 22 and the second display frame 23. The streaming playback video data 24 can be displayed in the first display frame 22, and the playback video data 25 after the download can be displayed in the second display frame 23 in conjunction with the display of the streaming playback video data 24.

  Therefore, the data size of the streaming playback video data 24 can be made smaller than when the streaming playback video 24 is displayed in a single display frame as in the prior art.

  In addition, the playback video data 25 after download and the still image data 26 after download have a smaller data size than the streaming playback video data 24, and the amount of calculation required for playback is small. Can be displayed quickly. Therefore, the playback video data 25 after the download and the still image data 26 after the download can be displayed on the display unit 21 in conjunction with the streaming playback video data 24, and the display size can be increased.

  Thereby, the data size of the whole data that the Internet terminal 20 receives from the information providing server 10 can be reduced, the load on the network can be suppressed, and a comfortable communication environment can be maintained. Therefore, clear IR activity information in an interview format can be supplied at a low cost with a relatively small data size.

  Also, since the questioner's question is usually short, the respondent's answer is long, and the respondent uses a chart for the answer, the playback video data 25 is assigned to the question video data by the questioner after the download is completed, and the streaming playback video A virtual interview can be established by assigning the data 24 to the moving image data of the answer by the respondent and assigning the playback still image data 26 after the download is completed to the still image data of the chart used by the respondent for the answer. The display space can be effectively utilized by switching the moving image data of the question by the questioner to the still image data of the chart used by the respondent.

  Further, compared to the conventional method of displaying a streaming playback moving image in a single display frame, the production of content can be facilitated and the cost can be reduced. For example, in the conventional case, two directors and an interviewer need to be at the video shooting site at the same time, but according to the present system, it is possible to shoot at different locations. Accordingly, the number of equipment such as a camera and a voice microphone is small, and the time required for preparation can be shortened. In addition, when explaining using charts, since the directors and interviewers have held explanations in the past, the charts displayed on the display screen of the terminal were small and could not be seen well. On the other hand, in this system, since the chart can be displayed in the second display frame 23 in conjunction with the director's moving image displayed in the first display frame 22, it can be shown more clearly.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, the case where the first display frame 22 and the second display frame 23 have substantially the same size has been described as an example, but the size ratio may be changed according to the data communication speed. Good.

  For example, in an Internet environment where the line speed is poor and high-speed communication cannot be secured, the data size of the streaming playback video data 24 to be streamed is reduced by making the first display frame 22 smaller and the second display frame 23 larger. May be reduced, and the data sizes of the playback video data 25 after download and the still image data 26 after download may be increased. According to this, the data size of the entire data can be further reduced, and a moving image can be displayed without stress even in a poor Internet environment.

It is a whole block diagram which shows this Embodiment. It is a figure explaining the screen displayed on an internet terminal. It is a figure explaining the screen displayed on an internet terminal.
