Abstract

A voltage acquisition method and device, and a storage medium. The method comprises: setting a voltage value of a modulator to be a pre-set initial voltage value and sending a video stream at a pre-set frequency point value to a set top box; when it is monitored that the set top box outputs the video stream, intercepting and saving a first pre-set number of frames of pictures from the video stream; determining the current playing state of the video stream according to the pictures; adjusting the voltage value of the modulator and monitoring the next playing state in real time, and determining whether the playing state has changed; and if the playing state has not changed, cyclically executing the step of adjusting the voltage value of the modulator and monitoring the next playing state in real time, and comparing the current playing state with the next playing state to determine whether the playing state has changed, until the playing state has changed twice, and respectively recording two voltage values corresponding to the two changes as a first voltage threshold and a second voltage threshold corresponding to the pre-set frequency point value.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a voltage collection method, device and storage medium. Background technique [0002] The tuner module of the set-top box is a very important part of the set-top box hardware, also known as the low-noise amplifying frequency converter. The sensitivity index is the most important index in the set-top box. The existing method for collecting the voltage of the video stream signal received by the tuner module of the set-top box mainly includes two collection methods, manual test collection and passing the bit error rate test index. [0003] 1. Manual testing takes a long time to collect the machine, and it is easy to make mistakes in the case of human fatigue. The threshold voltage collection results need to be manually entered into the spreadsheet, which affects work efficiency, increases human resource consumption, and increases product development costs. [0004] 2. It is...
