2.1.1.1.2.2 Transmitters

When the RegisterDevice action of the transmitter's X_MS_MediaReceiverRegistrar:1 service is invoked, it MUST decode the Base64-encoded data block sent by the receiver from Base64 to binary. The resulting BLOB is the registration request message, and it MUST be used as specified in section 2.1.1.1.2. For information on Base64 see [RFC3548]

The transmitter MUST encode the binary registration response message to Base64 format [RFC3548]. The Base64-encoded data block MUST then be sent to the receiver as the response to the RegisterDevice action.

The registration request and registration response messages are defined in sections 2.2.1.1 and 2.2.1.2, respectively.
