The receiver 3) is associated with the network B sink (video / map data receiver 7), the command is transmitted from each component of the in-vehicle network A and the network B to a desired destination, the network B Controls the operation of each component.

  FIG. 2 is a flowchart showing processing executed in the gateway network system 100.

  First, the gateway unit 4 recognizes the gateway network system 100 when the network B is connected to the in-vehicle network A (step S1).

  Next, the gateway unit 4 acquires device information of each component of the in-vehicle network A and the network B (step S2), and uses the network A sink (audio data receiving unit 3) and the corresponding network B sink. Associate (step S3). Here, for example, the sync associated with the audio data receiving unit 3 is the video / map data receiving unit 7. Since the network B is IEEE 1394, the gateway unit 4 is connected to the audio data receiving unit 3 based on device information (specifically, ModelInfo (model information) of ConfigRom) acquired from each component of the network B. Associate with the corresponding sink.

  In the above example, the audio data receiving unit 3 and the video / map data receiving unit 7 are associated with each other. However, the present invention is not limited to this.

Specifically, the gateway unit 4 includes table information indicating the relationship between the FBlockID, InstID, and functional block name in FIG. 3, and based on the FBlockID and InstID included in the transmission request (Allocate command) received in step S6, Determine the destination of the send request (Allocate command). Therefore, the operation control unit 1 can output information for specifying a transmission source of DVD data that cannot be reproduced by the in-vehicle network A from the in-vehicle network A.

  The DVD data transmission unit 5 transmits DVD data including audio data and video data to the gateway unit 4 (step S10). Based on the reception request in step S8, the gateway unit 4 transmits the audio data included in the DVD data to the audio data receiving unit 3, and the video data included in the DVD data is transmitted to the audio data receiving unit 3 in step S3. It transmits to the associated video / map data receiving unit 7 (step S11). The audio data receiving unit 3 reproduces the audio data included in the DVD data, and the video / map data receiving unit 7 reproduces (displays) the video data included in the DVD data (step S12). Exit.

  As described above in detail, the gateway unit 4 is connected to the sinks of the in-vehicle network A and the network B (that is, the audio data receiving unit 3, the video / map data receiving unit 7, and the audio data when the in-vehicle network A and the network B are connected. The device information of the receiving unit 8) is acquired, and based on the acquired device information, the audio data receiving unit 3 that receives and reproduces audio data and the video / map data receiving unit 7 that receives and reproduces video data are associated with each other.
