Thanks for your reply. I am sure it is a IR remote. And I think the problem is that the IR codes is too long. I tried to force the remote mode for my this remote, but I don't know the right format for config file.

That looks like the NEC protocol. Start with the generic/NEC.conf file try irrecord again.
