摘要： A media information distribution service system, such as a video-on-demand service system, is disclosed which, even if the capacity of a line is small and the number of lines connected to a media server, such as a video server, has to be increased accordingly, permits an uneconomical increase in the number of line circuits in the media server to be checked. In the system, a subscriber group that a distributor accommodates can be associated with a plurality of distributor-side paths on a distributor-side line. Each of the distributor-side paths is connected to a respective one of server-side paths on separate server-side lines connecting the media server and an exchange. In sending media information to a subscriber group, an in-server path control unit installed in the media server is permitted to select a free one out of server-side paths on server-side lines allocated for that subscriber group and activates a line interface corresponding to the free server-side path.
摘要翻译：公开了诸如视频点播服务系统的媒体信息分发服务系统，即使线路的容量小，并且连接到诸如视频服务器的媒体服务器的线路的数量必须相应地增加，允许要检查的媒体服务器中的线路电路的数量不经济地增加。在系统中，分配器容纳的用户组可以与分配器侧线路上的多个分配器侧路径相关联。每个分配器侧路径在连接媒体服务器和交换机的分开的服务器侧线上连接到服务器侧路径中的相应一个路径。在向用户组发送媒体信息时，允许安装在媒体服务器中的服务器内路径控制单元在分配给该用户组的服务器侧线路上从服务器侧路径中选择一个空闲的路径，并激活对应的线路接口到免费的服务器端路径。

摘要： By transmitting an analog CATV signal output from a CATV-HE (CAble TeleVision-Head End) to an HDT (Host Digital Terminal), an analog transmission channel for transmitting the analog CATV signal to an ONU (Optical Network Unit) is included in a path housing a digital transmission channel for transmitting a digital service signal for individual distribution service to the ONU. Furthermore, a digital service signal for multicast service is modulated and converted into an analog service signal by a modulator in the HDT. Then, the converted signal is mixed with the analog CATV signal, and transmitted to the ONU. Accordingly, each of the ONUs is equipped with only a built-in modulator for modulating the digital service signal for individual distribution service.

摘要： The present invention aims at providing an ascending transmission speed controlling method and a communication system in an ATM-PON (asynchronous transfer mode-passive optical network), in which ascending transmission speeds on the PON are dynamically allocated corresponding to actual transmission states of communication channels of a best effort type, to thereby effectively utilize respective bands. To this end, according to the present invention, in an OLT (optical line termination) constituting the ATM-PON system, active/inactive states of communication channels are identified based on receiving states of ascending data cells transmitted from ONU's of subscriber side, respectively, and a congestion state of the ATM network is recognized by extracting B-RM (backward resource management) cells from descending data cells, respectively, transmitted from the ATM network, so that ascending transmission speeds on the PON are allocated to communication channels corresponding to service categories, based on such as the thus recognized information.
