The embodiment of the invention discloses an apparatus and method enabling a client device to play radio and television programs and belongs to the radio and television field. With the apparatus and method adopted, client devices with different radio and television coaxial wiring ports can play radio and television programs, and the probability of lag in playing can be decreased, and therefore, user experience can be improved. The method includes the following steps that: a radio and television end device receives a first request message transmitted by a client device through a second network, wherein the first request message contains a target frequency point and is used for making the radio and television end device obtain the detailed information of a target radio and television program corresponding to the target frequency point; the detailed information of the target radio and television program is extracted out from source radio and television network signals outputted from a radio and television coaxial line according to the target frequency point; the detailed information of the target radio and television program is converted into a first data packet which satisfies a network protocol of the second network; and the first data packet is transmitted to the client device through the second network, so that the client device can play the radio and television program according to the first data packet.
