To provide a television receiver, server, operation system for the television receiver, and operation program of the television receiver for enabling an operator to control the television receiver as intended without causing a conflict between user operation and operator operation without using a gateway, a television receiver 110 capable of being operated via a network has an operation instruction receiving section 112 that receives an operation instruction given via the network, an operation accepting section 111 that accepts operation that is directly given without via the network, a restriction determining section 113 that distinguishes between the operation based on the operation instruction received in the operation instruction receiving section 112 and the operation accepted in the operation accepting section 111 and that determines whether or not to restrict each operation, and a receiver-side control section 115 that executes control associated with the operation when the restriction determining section 113 determines not to restrict the operation.
