Abstract

The invention discloses a method for indicating a digital television signal and a digital television using the same. The indicating method comprises the following steps of: acquiring an intensity level L of the digital television signal; acquiring a quality index C of the digital television signal; giving a comprehensive quality level Q according to the intensity level L and the quality index C of the digital television signal; and displaying the comprehensive quality level Q of the digital television signal. The digital television is characterized by adopting the signal indicating method. The method for indicating the digital television signal gives the comprehensive quality level, and is simple and easy to identify according to the signal intensity and quality of the digital television signal.

Description

technical field [0001] The invention relates to the field of digital television, more specifically, to a digital television signal comprehensive quality indication method and a digital television using the signal indication method. Background technique [0002] One of the differences between digital TV signals and analog TV signals is that when the analog TV signal is interfered, the interference signal can be displayed in the image effect, while when the digital TV signal is interfered, the image may It will not be affected in any way. When the strength of the interference signal exceeds the error correction capability of this system, there will be mosaics, or even cannot be displayed. In this way, when the digital TV signal is very strong, the strong interference signal will also cause poor reception, that is, strong signal strength does not necessarily lead to good reception. [0003] At present, there are usually two ways to indicate the signal status of digital TV. The...
