Abstract: PURPOSE: A multicast routing method is provided to efficiently use quality service and network resources in real time, by calculating the average delay time from sources to target places and by forming a multicast tree within a short time in the multicast network that requests the quality service for the delay time. CONSTITUTION: The delay time in the multicast paths between a source and a target node is calculated, and an average delay time(A0(T)) is obtained, the average delay time(A0(T)) being updated whenever a new target node is added to the multicast tree(S10). The shortest path in the multicast tree, which has the delay time( D(e)) to the newly added target place that is close to the average delay time(A0(T)), is formed under the condition of the value of a difference limit(delta) which is a maximum delay time(S20). It is checked if the formed multicast tree satisfies the quality service condition in which the delay time is smallest. If the quality service condition has not been satisfied, the multicast tree is formed again(S30).

Abstract: PURPOSE: A data reading/writing method between devices using a communication media manager is provided to reduce a trial and error of other software factors and improve a performance of the whole HAVI device by allowing a CMM(communication media manager) to process a block reading/writing between devices adopting an HAVI structure and other devices. CONSTITUTION: When a power-on or a standby(BusReset) occurs in an HAVI device such as a DTV(S10), HAVI software factors request reading/writing for its own construction ROM or a construction ROM of other device as necessary(S20). When a block reading request is received from each device, an 1394 CMM performs a data reading/writing request for a data block from a corresponding device(S30). The 1394 CMM determines whether the data reading/writing device supports a block reading/writing(S40). If the corresponding device supports the block reading/writing, the 1394 CMM transmits the read data to the corresponding HAVI software factor(S90) for a normal operation(S100). If the corresponding device does not support the block reading/writing, an error response of resp_type_error is transmitted to the 1394 CMM(S50). Upon receipt of the error response of resp_type_error, the 1394 CMM recognizes a data quadlet, a data processing rage of the corresponding device(S60). The 1394 CMM repeatedly stores as much as the length of the recognized data quadret and reads all of the corresponding block sizes(S70). The 1394 CMM reassembles the data as repeatedly read for 8 times and transmits them in a block unit to an upper software factor(S80).
