摘要： In a multipoint videoconferencing system including a plurality of visual telephone terminals and a multipoint control unit (MCU) connected thereto, shares of the respective visual telephone terminals are determined in the MCU, based on determination of a speaker determined from voice levels and/or amount of movement in the respective visual telephone terminals. The respective telephone terminals generate pictures at picture rates defined by the respective shares, and generate video data from the pictures at data rates defined by the respective shares. Video data generated in each visual telephone terminal are multiplexed in time division multiplexer in the MCU, and are distributed to the other terminals.

摘要： To provide a technology for easily distributing an image in a requested photograph direction. Photograph images, which are photographed by turning a photographing apparatus and continuously photographing the periphery of the photographing apparatus, are stored in a storing region. Any direction in a photograph range of the photographing apparatus is specified and a distribution request of an image photographed in the specified direction is received. A reading start position on one image is determined from the continuous photograph images in accordance with the specified direction of the distribution request. A part of the photograph image is read out from the start position as a distribution image. The distribution images are read out from the positions moved correspondingly to the turns from the start position on the image following the photograph image. The distribution images are distributed to request destinations of the distribution requests.

摘要： A transmission system is provided having a sender side apparatus, a receiver side apparatus, and a transmission line connecting the sender and receiver side apparatuses. The sender side apparatus provides a selector for receiving image data signals of a plurality of channels in parallel and, frame by frame, selects an image data signal of one of the plurality of channels for each frame. The selector discards the image data signals of the other of the plurality of channels. A coding unit codes the image data signal which is selected for each frame by the selector, by interframe difference coding. A monitoring unit monitor data amounts of interframe differences in the image data signals of the respective channels. A control unit determines which one of said plurality of channels is to be selected by the selector, based on the data amounts of interframe differences in the image data signals of the respective channels, and adaptively controls the selector in accordance with this determination. Channel information is generated indicating the above one of the channels determined by the control unit for each frame. Frame by frame, the image data signal coded by the above coding means is transmitted, together with the above channel information corresponding to the coded image data signal. The receiver side apparatus receives the transmitted image data signal, together with the channel information, and a unit for decodes the received image data signal for each frame.

摘要： A receiving unit receives a group of packets transmitted from a transmitting apparatus. A detecting unit detects a missing packet based on the received group of packets. A first output unit outputs data corresponding to the group of packets, irrespective of a result of the detection by the detecting unit. A transmitting unit transmits a retransmission request for the missing packet to the transmitting apparatus. A re-receiving unit receives the missing packet retransmitted from the transmitting apparatus in response to the retransmission request. A second output unit outputs data corresponding to the group of packets and the retransmitted packet.

摘要： An object of the present invention is to enable a real-time distribution even if the band of a network varies. A distributing apparatus receives a packet retransmission request or a packet restoration notification, which is transmitted from a receiving apparatus, with an error information receiving unit. If the number of received retransmission requests or that of restoration notifications becomes equal to or larger than a certain value, a distribution band controlling unit decreases a band used to distribute a packet by a certain band.
