  • step ST50 If it is determined in step ST45 that the data is not from a DVD, other processing is performed (step ST50). That is, the processing for the in-vehicle device other than the in-vehicle device described above, that is, the DTV as the AV device 4 and the in-vehicle camera 5 is performed in the same procedure as described above. Thereafter, the sequence returns to the main process.
