Description

  The present invention relates to an information delivery output system, an information delivery device, an information output device, an information delivery output method, an information delivery method, an information output method, a program, and a recording medium that support a presentation corresponding to a plurality of output devices.

  Conventionally, when performing a presentation, a presenter reference video output device and a viewer reference video output device are prepared for each presenter and viewer, and the presentation is sometimes performed.

Japanese Patent Application Laid-Open No. 2004-133620 proposes that the presentation can be smoothly performed by displaying information (elapsed presentation time, presentation scenario, etc.) that can be referred to only by the presenter on the presenter reference video.
JP 2002-196740 A

  However, in the conventional technology such as Patent Document 1, the information that can be referred to by the viewer is a subset of the information that can be referred to by the presenter. Therefore, a video that can be referred to only by the viewer is displayed on the viewer reference video. It was not possible.

  Therefore, for example, in an international conference, etc., a plurality of video output devices for viewer reference are prepared, presentation videos in different languages are output for each video output device, and the presenter also uses a language different from those videos. When we wanted to make a presentation while referring to the written screen, we could not handle it.

  Conventionally, in such a case, it has been necessary to prepare a video distribution device for each language individually, store presentation materials in different languages, and make presentations while simultaneously operating the plurality of video distribution devices. I was forced to work hard.

  For this reason, there has been a risk that an operation is mistaken and outputs from a plurality of video output distribution terminals are not synchronized.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide an information distribution device that uses the same presentation data composed of a plurality of pieces of output information stored in a memory. The information is distributed to an output device, and each information output device has an extraction setting for selecting and extracting output information to be output from presentation data composed of a plurality of output information distributed from the information distribution device. Each information output device selectively extracts a plurality of output information to be output from the presentation data received from the information distribution device based on the set extraction setting, and each information output device Generating one combined output information for synthesizing the plurality of extracted output information and outputting the combined output information to the output means; Information output apparatus, information distribution apparatus, information output apparatus, and information distribution output method capable of outputting different output information for each information output apparatus from the presentation data and realizing a smoother and more flexible presentation And an information delivery method, an information output method program, and a recording medium.

In the distribution output system, the information distribution device stores storage data for storing presentation data composed of a plurality of output information, and the same presentation data composed of a plurality of output information stored in the storage means. A first distribution unit that distributes to each of the information output devices, and each of the information output devices outputs itself from presentation data composed of a plurality of output information distributed from the information distribution device. Setting means for performing extraction setting for selecting and extracting output information to be Based on the extraction setting set by the setting means, an extraction means for selectively extracting a plurality of output information to be output from the presentation data received from the information distribution device; and a plurality of the extraction information extracted by the extraction means And combining means for generating one combined output information for combining the output information and outputting it to the output means.

  According to the present invention, the information distribution device distributes the same presentation data composed of a plurality of pieces of output information stored in the memory to each of the information output devices, and each of the information output devices from the information distribution device Performs extraction setting for selecting and extracting output information to be output from presentation data composed of a plurality of output information to be distributed, and each information output device is configured based on the set extraction setting. , Selecting and extracting a plurality of output information to be output from the presentation data received from the information distribution device, and the information output devices synthesize the plurality of output information extracted and output to the output unit Therefore, different output information is generated for each information output device from presentation data from one information distribution device. It can be output information.

  Therefore, the same presentation data distributed from the information distribution apparatus has a function of extracting output information displayed by itself for each information output apparatus for viewer reference (including information output apparatus for presenter reference). Thus, the plurality of information output devices can output different outputs, and the smoother and more flexible presentation can be realized.

  As a result, for example, at an international conference, etc., a plurality of information output devices for viewer reference are prepared, presentation videos in different languages are output for each information output device, and the presenter also has a language different from those videos. Even when it is desired to make a presentation while referring to the screen of the information distribution device described in the above, presentation data composed of a plurality of pieces of output information respectively described in a plurality of languages is distributed from one information distribution device, Presentation output in different languages can be performed on a plurality of information output devices.

  Therefore, unlike the conventional case, it is not necessary to prepare an information distribution apparatus for each language individually, store presentation materials in different languages for each language, and operate the plurality of information distribution apparatuses at the same time. All the fears that the outputs from a plurality of information output distribution devices will not be synchronized by mistake will be eliminated.

Layer information to be extracted by the information extraction unit 309 is set in the information extraction unit 309 from the information described in the “layer” attribute of the “device” element.

  Next, in step S503, a video output information distribution process (details are shown in FIG. 10) is executed, and the process ends.

  FIG. 10 is a flowchart showing an example of the second control process in the video distribution system of the present invention, and corresponds to the video output information distribution process in step S503 of FIG.

In the figure, S601 to S605 indicate steps.

  In step S601, the information compression unit 307 waits for processing until the occurrence of a video distribution trigger (such as a return key input from the input device 212 or a mouse left button click), and determines that a video distribution trigger has occurred. Shifts the processing to step S602.

  In step S602, the information compression unit 307 displays presentation data corresponding to the number of times of video distribution trigger generation from the video output information registration file (for example, when the number of times of video distribution trigger generation is “2”, the presentation of Operation 2 shown in FIG. 11). Data) (compression of video output information).

  In step S603, the communication unit 308 distributes the presentation data (for example, FIG. 11) extracted by the information compression unit 307 in step S602 to the video output terminals 1 to 3 and the information extraction unit 309 (distribution of video output information). ).

In the figure, S401 to S407 indicate steps.

  In step S401, when the communication unit 301 receives the output layer setting information (information of “Operation 0”) shown in FIG. 8 from the video distribution terminal 5, in step S402, the display information setting unit 305 receives in step S401. Among the ID attributes in the “device” element in the output layer setting information, the “device” element that matches the own IP address is searched. The display information setting unit 305 refers to the “layer” attribute of the “device” element when the “device” element of the IP address that matches the IP address of the display information setting unit 305 exists. Then, the display information setting unit 305 sets the layer information to be extracted by the information extraction unit 302 in the information extraction unit 302 from the information described in the “layer” attribute.

  Next, in step S403, when the communication unit 301 receives presentation data as video output data including the multiple layer information shown in FIG. 11 from the video distribution terminal 5, in step S404, the information extraction unit 302 Check whether the video output end command is described in the presentation data. If it is determined that the video output end command exists, the video output processing is terminated, while the video output end command does not exist. If it is determined, the process proceeds to step S405.

  Next, in step S405, the information extraction unit 302 selects and extracts layer information to be output by the video output terminal itself set in step S402 from the presentation data. For example, if the set layer information to be extracted is “layer A”, “layer C”, as shown in FIG. 13, “layer A”, “layer B”, “layer C” in the presentation data. Then, “Layer A” and “Layer C” are extracted.

  Next, in step S406, the information expansion unit 303 analyzes each piece of layer information extracted in step S405, and combines (expands) it into one layer composite output video information as shown in FIG. To do.

  Next, in step S407, the video display unit 304 outputs video to the output device 205 based on the layer composite output video information generated in step S406, and shifts the processing to step S403.

  FIG. 14 is a diagram schematically illustrating a process of combining a plurality of layer information extracted by the information development unit 303 illustrated in FIG. 3 into a single layer composite output video information.

  Note that the video output process shown in FIG. 12 described above is also executed in the video distribution terminal 5. In this case, it is realized by the CPU 209 shown in FIG. 2 reading the program stored in the data storage unit 211 on the RAM 210 and executing it. In this case, the extraction layer setting process for the information extraction unit 309 in steps S401 and S402 is not executed because it has already been set in step S502 in FIG.

  Hereinafter, a case where the processing of the flowchart of FIG. 12 is executed in the video distribution terminal 5 will be described.

  First, in step S403, when the information extraction unit 309 receives the presentation data including the multi-layer information shown in FIG. 11 from the communication unit 308, in step S404, the information extraction unit 309 outputs the video in the presentation data. Check whether the end command is described, and if it is determined that the video output end command exists, the video output process is terminated, while if it is determined that the video output end command does not exist, The process proceeds to step S405.

  In step S405, the information extraction unit 309 selects and extracts layer information to be output by the video output terminal itself from the presentation data.
