How to process OrientBinaryObject

I was querying data from OrientDB, by pyorientdb.
my code is:
query_data_list = client.query("select from Brand where brand_name = ‘huawei’ ")
the response is:
{’@Brand’:{‘brand_name’: ‘huawei’, ‘brand_id’: ‘105320’, ‘out_Category2Brand’: <pyorient.otypes.OrientBinaryObject object at 0x7f03920cc940>}

My question is, how can I process the OrientBinaryObject .
After calling method in OrientBinaryObject, I got bytes like below.
b’\x01\x00\x00\x00\x02\x00;\x00\x00\x00\x00\x00\x00\x83\xec\x00@\x00\x00\x00\x00\x00\x00\x84\x00’

What is that, how can I process these bytes next?

Thanks
