Information processing device for network system, a method thereof and recording medium recorded a program for such method

摘要

Analog connections between plural electronic devices in an integrated digital network system connected via the IEEE-1394 bus can be easily recognized according to the invention. A DVHS requests an IRD, which are connected to the IEEE-1394 bus, to read the object entry which describes the object ID of an oEXT of the IRD (step 21). The IRD opens the plug descriptor stored therein (step 32). Then, the IRD reads out the contents of the object entry which describes the object ID of the oEXT from the plug descriptor opened in step 32, and transfer the contents thereof to the DVHS (step 33). The DVHS is allowed to recognize the status of analog connections from the contents of the object entry thus transferred (step 23).
