description The utility model discloses a digital STB based on big dipper communication is used, including main chip, the TS of this main chip end, USB2 end are connected with chip UDRM, chip UDRM connection DEMOD demodulator, signal transceiver's TUNER end is connected to the DEMOD demodulator, signal transceiver includes wired signal transport module CM, WIFI module, be provided with RGMII quadbit data transmission interface on the main chip, with the RGMII quadbit data transmission interface interconnect on the signal transceiver. The utility model discloses strengthened signal transmission's ability, security chip through HI3716CV200 double -core chip and UTI1203 is connected, makes signal transmission have more the security, and what adopt at HI3716CV200's TS end is that double - circuit TS flows the descrambling connected mode, can reduce outside interfering signal, make televise more smooth.
