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.

摘要： An IP-data transmitting apparatus performs an error correction coding by classifying data into a layer indicative of the priority order of the data based on importance and vulnerability of information included in the data, and combining a plurality of data components into combination patterns. The number of the combination patterns is specified with respect to each layer with predetermined priority order.

摘要： A system and method to adaptively control a process of distributing video information over a network. Each client data terminal subscribing to video services has a performance level reporting unit which sends a performance level message Da indicating what resources and computing power the terminal has. Each terminal also has an error status monitor which sends an error status message De. A video coder produces coded data Dc by coding source video signals, based on the received performance level messages Da and error status messages De. The traffic of this coded data Dc is dynamically varied by a dynamic traffic controller, and a distribution unit transmits the resultant video stream Di over the network, using IP multicasting techniques. A video decoder in each client terminal adaptively decodes the received video stream Di.

摘要： An image, which is captured by a camera that a worker, etc., carries, is once stored in a ring buffer memory for storing image signals. The image is extracted from the ring buffer memory, and a quasi-moving image is generated. In a normal state, the quasi-moving image is displayed on a monitor of a center such as a control room, etc. via codecs on transmitting and receiving sides. When a user viewing the monitor makes a request to view a sharp image of a particular frame, or the high-quality motion of a subject while viewing the frames preceding or succeeding a particular frame, the image frame or frames are read from the buffer memory for storing image signals, and displayed on the monitor.

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.
