Embodiment 1

[0033] see figure 1 , which is a schematic structural diagram of a variety of signal source transceiver control devices in Embodiment 1 of the device of the present invention, including a tuner 1, a channel control switch 2, a demodulator 3, a processor 4, a network signal transceiver 5, and an FM signal receiver Device 6, audio amplifier 7, audio channel selection switch 8, relay 10, power amplifier 11 and speaker 12, wherein,

[0034] Tuner 1 receives the cable digital TV signal and the terrestrial digital TV signal, and converts the received signal into an intermediate frequency signal;

[0035] The processor 4 selects the received signal through the channel control switch 2. When selecting to receive the cable digital TV signal, the channel control switch 2 connects the cable digital TV intermediate frequency signal output by the tuner 1 to the processor 4, and the processor 4 is connected to the cable digital TV intermediate frequency signal. The signal is demodulated an...

Abstract

The invention discloses a transmitting / receiving control device and method of multiple signal sources. The device comprises a tuner, a channel control switch, a demodulator, a processor, a network signal transceiver, a frequency modulated signal receiver, an audio amplifier, an audio channel selector switch, a relay, a power amplifier and a loud speaker; the tuner receives a wire digital TV signal and a ground digital TV signal, and converts the received signal into an intermediate frequency signal; the processor selects the received signal through the channel control switch; when the processor selects to receive the wire digital TV signal, the channel control switch connects the wire digital TV intermediate frequency signal output by the tuner with the processor, the processor performs demodulation and de-multiplexing on the wire digital TV intermediate frequency signal to divide the same into the video stream, the audio stream and the data stream. By receiving, processing, amplifying, performing preference setting and judgement and outputting on the signal with multiple signal sources, the control is flexible and convenient.

Description

technical field [0001] The invention belongs to the field of broadcasting, and in particular relates to a device and method for controlling transmission and reception of multiple information sources. Background technique [0002] Although my country's informatization construction has made great achievements in recent years, and the popularization of the Internet, television, and mobile phones has greatly improved the informatization level of rural areas, some government information from the township and county governments, as well as local However, some agriculture-related information cannot be conveyed to farmers in time. [0003] With the large-scale construction and migration of the cable digital TV network, many radio programs, convenient information, and life services are loaded into the digital TV network, and relevant government departments also transmit many important emergency information to thousands of households through the cable digital TV network . The curre...
