Abstract

The invention discloses a set-top box communication circuit, a set-top box and a set-top box system. The set-top box communication circuit consists of a high pass processing circuit, a band pass processing circuit, a low pass processing circuit, a coaxial cable, an inductor and a controller; a first end of the high pass processing circuit is connected with the first end of the coaxial cable, and the second end of the coaxial cable is connected with a converter; the first end of the band pass processing circuit and the first end of the low pass processing circuit are connected with first end ofthe coaxial cable through the inductor; the second end of the band pass processing circuit and the second end of the low pass processing circuit are connected with controller; and the high pass processing circuit, the band pass processing circuit and the low pass processing circuit screen signal frequency input by the converter, and the controller processes the screened signal. The technical scheme disclosed by the invention transmits signals with three different frequencies through the coaxial cable.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a set-top box communication circuit, a set-top box and a set-top box system. Background technique [0002] With the advent of the analog-to-digital era, it is becoming more and more common to have several set-top boxes in a household. The set-top box includes a master set-top box and a slave set-top box, and communication needs to be performed between the master top box and the slave set-top boxes. [0003] Currently, the communication between the master set-top box and the slave set-top box is mainly realized through wireless means, for example, infrared, bluetooth, or wifi. Data signals and control signals received from satellites are transmitted wirelessly. [0004] However, wireless communication has problems of unstable communication and error-prone data reception. Contents of the invention [0005] The main purpose of the present invention is to provide a communi...
