The invention provides a control device and control method. The control device includes a processing unit, an audio selection circuit, a power amplification circuit, a plurality of communication circuits, and a power supply circuit. The first input end of the audio selection circuit is electrically connected with the first port of the processing unit; the first input end of the power amplification circuit is electrically connected with the output end of the audio selection circuit; the first ports of the communication circuits are electrically connected with the second ports of the processing unit, the first signal ports of the communication circuits are electrically and correspondingly connected with the second signal ports of a plurality of audio signal reception decoding plates of a broadcasting terminal one by one; and the output end of the power supply circuit is electrically connected with the third port of the processing unit, the second input end of the audio selection circuit, and the second input end of the power amplification circuit. The control device and control method enable the broadcasting terminal to support multiple audio transmission modes while reducing the production cost of the broadcasting terminal.
Description
technical field [0001] The present invention relates to the technical field of broadcasting, in particular to a control device and a control method. Background technique [0002] As a streaming media signal, the audio signal has multiple transmission modes. Usually, when two or more audio transmission modes appear in a broadcast terminal product, it is necessary to target each transmission mode in the product design and development process Design circuits, write programs; and when the application scenarios and customer needs change, the above transmission modes may need to be recombined to produce new forms of broadcast terminal products. At present, in order to meet new market demands, the common practice is to change the circuit layout repeatedly for the same technical solution, resulting in a lot of duplication of labor. [0003] To sum up, currently, it takes a lot of labor and time to enable the broadcasting terminal to support multiple audio transmission modes, result...
