Patent ID: 7177959

Claim:
An information signal processing apparatus connected to a connection control network, comprising: event reception means for receiving a predetermined event instruction irrespective of a type of high level protocol by using predetermined addresses as registers, which are allocated in a serial bus register space in an address space of said information signal processing apparatus connected to a communication control bus complying with IEEE 1394; event generating means for generating an event corresponding to the received instruction when said event reception means receives an event instruction; detecting means for detecting generation of a bus reset on a remote bus connected to said communication control bus via a bridge by referring to a part of said predetermined addresses which is used for indicating bus reset status on the remote bus; and informing means for informing a high level protocol layer of generation of a bus reset on the remote bus when said detecting means detects the generation of the bus reset, wherein said apparatus does not execute a bus reset process on said communication control bus when said detecting means detects generation of a bus reset on the remote bus, and said high level protocol layer re-establishes a connection with a node connected to the remote bus when said informing means informs said high level protocol layer of the generation of the bus reset on the remote bus while said high level protocol layer establishes a connection with the node.
