Decoder access method, service server and spliced wall system

The invention discloses a decoder access method, a service server and a spliced wall system, and the method comprises: the service server receiving a service instruction transmitted by a client processor, converting the service instruction into a corresponding access instruction through service logic processing, and transmitting the access instruction to an access server through employing a load balancing algorithm; the access server receiving and responding to the access instruction, generating an equipment operation instruction from the access instruction by calling a decoder SDK, and sending the equipment operation instruction to a decoder; and the decoder receiving and responding to the equipment operation instruction, and establishing a secure link with the access server for data transmission. The embodiment of the invention provides a decoder access method, a service server and a spliced wall system, which realize access of a decoder to an access server through a decoder SDK, realize butt joint of the d
