摘要： Examples associated with room capture and projection are disclosed. One example includes an information management module that may maintain information regarding a virtual space and a first digital object within the virtual space. The first digital object may be associated with an artifact in a physical space. A room calibration module may map the virtual space to the physical space using sensors to detect attributes of the physical space. A capture module may record a modification to the artifact to be maintained by the information management module. A projection module may project a representation of a second digital object into the physical space. The representation may be projected based on a signal from the information management module.

摘要： A video display system which enhances the smoothness of meeting and includes a video information terminal device typified by a liquid crystal projector, a video display unit typified by a whiteboard, a server which stores information, a user terminal device typified by a mobile terminal held by a member of meeting is provided. A host of a meeting transmits information regarding time, members, and contents of the meeting to the server. A created reservation list and a created participant list of a meeting room are displayed on the video display unit by the video information terminal device. The display is updated depending on an attendance/nonattendance answer from a member. A diagram or letters written on the video display unit during the meeting are captured by the video information terminal device, inverted in brightness, stored in a memory, and displayed as a video image. At the end of the meeting, video data stored in the memory is stored as a file. When the meeting is resumed, the stored file is reproduced, developed in the memory, and displayed as a video image.

摘要： A communication terminal (2c) includes a drawing controller (201, 22) that displays an image being shared with a first communication terminal (2a, 2b) and a second communication terminal (50), the image having a plurality of image layers superimposed one above the other. In response to a user input for changing appearance of a first image layer of the image, the drawing controller (201, 22) stores information reflecting the change caused by the user input to the first image layer in a memory (2000), and generates an updated image having the first image layer that reflects the change caused by the user input, based on the information reflecting the change caused by the user input to the first image layer. The communication terminal (2c) further includes a first communication controller (21) to transmit the information reflecting the change to the first image layer to the first communication terminal to cause the first communication terminal (2a, 2b) to generate and display the updated image, and a second communication controller (81) to transmit the updated image having the first image layer that reflects the change to the second communication terminal (50) to cause the second communication terminal to store the updated image.

摘要： Embodiments of the present invention disclose a session information recording method, where the method is executed by a recording server, the recording server is connected to a unified communications system and is configured to record a media packet and a signaling packet generated in the unified communications system. The recording server associatively records a received media packet, a received signaling packet, or a combination thereof based on a session. The method provided in the present invention expands application scenarios of associative recording and can resolve a problem in the prior art that a media packet and a signaling packet cannot be associatively recorded in many scenarios.

摘要： A distribution control apparatus (2) is connected to a communication terminal (5) via a network (9). The distribution control apparatus (2) includes a receiving unit (31), a whiteboard control unit (22), a whiteboard unit (20), and a transmitting unit (31). The receiving unit (31) receives, from the communication terminal (5), operation data representing an operation performed by a user. When the operation is a stroke command, the whiteboard control unit (22) stores a series of coordinates entered onto the communication terminal (5) and contained in the operation data in a first storage unit (122) and generates stroke data representing a stroke from the stored coordinates. The whiteboard unit (20) stores the generated stroke data in a second storage unit (120) and generates video data by rendering the stroke data. The transmitting unit (31) transmits, to the communication terminal (5), converted video data obtained by converting the generated video data into a data format that allows distribution.
