摘要： In a CATV-LAN in which a plurality of modems transmit messages asynchronously from respective terminal apparatuses to an upstream transmission path and receives messages from a downstream transmission path, when a modem is transmitting a message, the resultant data which are received by that modem are compared with data of that message which have already been transmitted, and transmission is interrupted if the received data do not correctly match the transmitted data, due to conflict with data transmitted by some other modem. Each message contains information specifying its length, and when a non-transmitting modem receives a set of data whose actual length does not match a length value which is specified within the data, the data are discarded. It thereby becomes unnecessary to provide beat detection circuits in the modems, for detecting data conflict, so that system cost can be reduced.

摘要： A picture transmission system capable of establishing arbitrary picture connections with picture inputting units exceeding in number channel resources of a transmission medium for multiplexing and transmitting video information taken through the picture inputting units. A picture sending state storage unit provided corresponding to each of the picture inputting units virtually retains channel resources whose number equals the number of picture outputting units to which the picture inputting units are in connection. For picture connection switching from one picture outputting unit to a different picture inputting unit, the picture sending state storage unit gives its channel resource to the different picture inputting unit. The system is provided with a picture connection managing unit for controlling the picture connections between the picture inputting units and the picture outputting units. The picture connection managing unit accepts a picture connection request to perform the centralized management of channel resources of the transmission medium to allow dynamic channel resource allocation. Under control of the picture connection managing unit, the picture connection between the picture inputting unit and the picture outputting unit takes place through an allocated channel resource.

摘要： An object of the present invention is to enable to obtain moving picture data of a desired bit rate at a high speed without re-coding when the multi-screen image is generated by synthesizing a plurality of moving picture data. When a layout designating means (502) designates the arrangement of moving pictures, a bit-rate deciding means (503) instructs a frame-type deciding means (505) to decide a bit rate of the synthesized multi-screen, and a degree-of-importance deciding means (504) decides an assignment rate of the frame rate, the frame-type deciding means (505) decides a frame type of the moving picture data acquired by a data acquiring means (501) and asks a synthesizing means (506) to synthesize the screen. The multi-screen generated by the synthesizing means (506) is streamed onto the network via a data transmitting means (507).

摘要： Multimedia applications including a video and an audio are transmitted at respective adapted transfer rates in a server connected with a networks. The server operates on an operating system which permits a multithreading by allocating time slices to thread. For each application, data on a required transfer rate indicative of a permitted lowest transfer rate for the application is prepared. Threads are generated for respective applications. An initial number of slices are allocated to each thread to let said threads transmit said respective applications. A transfer rate of each thread is measured at a time interval. A number of slices to be allocated to each thread is calculated such that the measured transfer rate of each thread (i.e., each application) becomes equal to the required transfer rate of the application transmitted by the thread.
