Data stream communication device and data stream communication method

摘要

Through network, method and the device in order to communicate the streaming data of audio and the video stream etc with iso clo eggplant system are offered. Power line communication (50) network or the network which is made on the basis of other IP connection can be used. The hardware (82), to packet it converts streaming data such as MPEG streaming data, as for the packet, for example, each communication cycle (32a and 32b) in non competitive period inside, it is communicated in IP physical layer. As for reservation mechanism, making use of backoff technology, the single transmitter reserves the slot for iso clo eggplant communication of the specified data stream. Because as for the processing element, the plural transmitters can rival communication, packet conversion is processed only in order asynchronous communication the data competitive period (34) also in the remaining part of each communication cycle which is called. Addressing for iso clo eggplant communication is not IP addressing, it is done by MAC addressing. Concerning superior layer control mechanism, existing IP stack and protocol can be reused.
