                     Figure 7-6 – High-level procedural flows for video metadata or image metadata storage


            Figure 7-6 shows the procedural flows of the video metadata or image metadata storage in cloud storage
            system:

            (1)     The CU initiates a storage plan request and sends this request to the SCU.
            (2)     The SCU forwards this storage plan request to the CMU.

            (3)     The CMU authenticates the storage access permission and then sends this storage plan request to
                    the CSMU.

            (4)     The CSMU authenticates the storage access permission and then sends this storage plan request to
                    the CSAU.

            (5)     The CSAU returns a response to the CSMU when it is ready for this storage plan.
            (6)     The CSMU returns the CSAU information to the CMU.

            (7)     The CMU sends a response to the SCU.
            (8)     The SCU forwards this response to the CU.

            (9)     When  the  CU  receives  the  CSAU  information,  it  sends  the  video  metadata  or  image  metadata
                    storage request to the CSAU.

            (10)    When  the  CSAU  receives  the  storage  request,  it  sends  a  request  to  the  SCU  for  the  metadata
                    address.
