Problems solved by technology

Therefore, in order to ensure that the tuner 10 can normally output 13V and 18V voltages, the existing method is to manually measure whether a coaxial connector 11 of the tuner 10 that is connected to the coaxial cable can be used before the DVB-S TV 1 leaves the factory. Normally output 13V and 18V voltage, but this method is not only time-consuming and labor-intensive, but also increases the cost of testing

Embodiment Construction

[0035] see figure 2 As shown, the method for automatically measuring the output voltage of the tuner of the DVB-S receiving device of the present invention is applied to a DVB-S receiving device 2 of European regulations, and the DVB-S receiving device 2 can be built in a TV 3 , making the TV 3 a DVB-S TV capable of receiving DVB-S signals, or connecting it externally to the TV 3 so that the TV 3 can receive DVB-S signals. The DVB-S receiver 2 mainly includes a tuner 10, a SCART connector 21 electrically coupled with the tuner 10 and a display 31 of the TV 3, and a system chip (system on chip) electrically coupled with the SCART connector 21. chip, referred to as SOC)22.

[0036] see you again figure 1 As shown, the tuner 10 is electrically coupled to a satellite dish antenna 4 via a coaxial cable 100 for transmitting radio frequency signals (i.e. DVB-S signals), so as to receive a DVB-S signal received by the satellite dish antenna 4, And according to a channel selection ...

Abstract

A Digital Video Broadcasting-Satellite (DVB-S) receiver device includes a tuner, a SCART (Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) connector and a system on chip (SOC). The tuner is for generating an output voltage. The SCART connector is for receiving the output voltage. The SOC is configured to receive a voltage signal associated with the output voltage outputted by the SCART connector, to digitize the voltage signal into a digital value, and to determine whether the digital value conforms with a default value so as to output a determination result.

Description

technical field [0001] The invention relates to a DVB-S receiving device, in particular to a DVB-S receiving device which can automatically measure the output voltage of its tuner. Background technique [0002] see figure 1 As shown, the existing DVB-S TV 1 of European regulations receives digital TV signals through a satellite dish antenna 4, and then selects and uses from the digital TV signals through the built-in tuner (tunner) 10 of DVB-S TV 1. the TV programs the viewer wants to watch. In addition, the tuner 10 also needs to transmit voltages of 13V and 18V to a low-noise cable on the satellite dish 4 via a coaxial cable 100 (mainly used to transmit DVB-S signals) electrically coupled with the satellite dish 4. A down-frequency amplifier (Low Noise Block downconverter, LNA for short) 40 . Therefore, in order to ensure that the tuner 10 can normally output 13V and 18V voltages, the existing method is to manually measure whether a coaxial connector 11 of the tuner 10 ...
