Abstract

The invention discloses a satellite antenna control and reception decoding integrated device comprising a common radio frequency front unit, an audio frequency video decoding unit, and an antenna control unit; the common radio frequency front unit receives a satellite carrier wave signal from the satellite antenna, and outputs an automatic gain control signal, a carrier wave locking signal and an audio frequency video program transport stream signal; the audio frequency video decoding unit is connected with the common radio frequency front unit, and receives an audio frequency video program transport stream from the common radio frequency front unit; the antenna control unit receives the automatic gain control signal and the carrier wave locking signal from the common radio frequency front unit, and can adjust or lock a satellite antenna gesture according to the automatic gain control signal and the carrier wave locking signal. The satellite antenna control and reception decoding integrated device is high in integrated level, can improve a signal to noise ratio of the satellite signal, and is more convenient to maintain.

Description

technical field [0001] The invention relates to satellite communication technology, in particular to an integrated device for controlling satellite antenna and receiving and decoding. Background technique [0002] In the application of traditional satellite TV reception, the satellite receiver decoder (also known as satellite TV receiver, satellite TV set-top box) and the satellite antenna are completely independent system components. The two are manufactured by different companies and have a clear division of labor and standardized interfaces. Such as figure 1 shown. The satellite antenna is used to realize satellite acquisition and automatic tracking on the ship carrier to ensure that the antenna is always accurately aligned with the satellite under various motion states and environmental conditions, establish a steady-state satellite transmission link and continuously receive program carrier signals. On the premise of receiving a stable satellite TV program carrier sign...
