Being the manner which decides the topology of decisive of communication

摘要

Unidirectional data connection (610, 628 and 634) using, the master node which is connected mutually (602) with the slave node of one or more (614, 618 and 622) with the network which it possesses (600) the method of deciding topology is disclosed. The master node (602), in the node after the data is made available, the slave node (622), the node before (618) from the data is grasped, that the data which is grasped has the information of pass to the slave node from the master node. Bidirectional data connection between the nodes (628, 612 and 632) through, the further method of forming pass the slave node (622) from by transmitting the data to all nodes in regard to pass, is disclosed. With desirable execution example, the foam/home entertainment system which uses HDMI (600) is appropriate network, way functioning it does as a master node, for example the operational possible presentation component (TV (602))It possesses, the node of network is connected HDMI code set (608, 624 and 616) it will do doing, mutually. HDMI standard has, the DDC bus which corresponds to the aforementioned unidirectional data connection (610, 628 and 634) with, the CEC bus which corresponds to the aforementioned bidirectional data connection (628, 612 and 632) with.
