Abstract

The invention provides a method for realizing a high-definition hand-hold multi-functional digital video broadcasting-cable (DVB-C) detector. The detector comprises a mainboard with a high-definition decoding master chip, a keyboard plate, a signal demodulation board and a liquid crystal display (LCD). The method comprises the following steps: inputting a group of digital TV parameters by the keyboard plate, saving the parameters in the mainboard, and dispatching the function of each hardware module by the mainboard to finish detection of line signals. The method provided by the invention is used for checking and detecting signal lines, thereby reducing difficulties of the engineering.

Description

【Technical field】 [0001] The invention relates to the technical field of digital television, in particular to a method for realizing a high-definition hand-held multifunctional DVB-C detector. 【Background technique】 [0002] At present, with the development of digital TV and the extensive coverage of digital networks, digital signals have various differences according to geographical differences, which brings great difficulties to the installation and search of broadcasting and TV centers. Common monitoring equipment on the market can only Querying the strength and quality of the signal, it is impossible to receive digital signals normally and watch normal programs to ensure whether the signal has reached the correct index, which fails to reduce the difficulty of the project. And with the popularization of high-definition signals and the needs of the market, the requirements for product functions are higher and the requirements for practicability are stronger. With the cont...
