Embodiment Construction

[0051] Such as figure 1 As shown, a method for generating a digital television test signal in an embodiment of the present invention includes the following steps:

[0052] S1. The receiving user selects at least one target graphic element from the preset graphic element library according to requirements, and receives the attributes configured by the user for each target graphic element;

[0053] Among them, the preset graphic element library includes a plurality of preset graphic elements such as line segments, rectangles, triangles, circles, fans, sine waves, etc., which can be displayed on the interface to facilitate users to select, for example, the user selects rectangles and triangles , then both the rectangle and the triangle are target graphic elements;

[0054] Among them, the attributes include position, size, whether there is a border, whether or not to fill, etc. For example, for a line segment, the position includes the height value, the start position, the end po...

Abstract

The invention relates to the technical field of testing, in particular to a digital television test signal generation method and system and electronic equipment, and the method comprises the steps: receiving at least one target graphic element selected by a user from a preset graphic element library according to the demand, and receiving the attribute configured by the user for each target graphic element; and generating a digital television test signal according to all the target graphic elements with the configured attributes. On one hand, a user can conveniently and intuitively select the target graphic elements from the preset graphic element library, and the digital television test signal is generated according to all the target graphic elements with configured attributes, so that the difficulty of signal editing is greatly reduced, the efficiency of generating the digital television test signal is greatly improved, and the learning cost of the user is reduced; various preset graphic elements can be filled in the preset graphic element library according to actual conditions, and the method is suitable for editing complex digital television test signals.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method, system and electronic equipment for generating digital TV test signals. Background technique [0002] The digital TV test signal is the signal content used to test the digital TV display equipment, mainly to inspect the compatibility of the digital TV display equipment to various signal content and formats, the display performance, and the integrity of the functions. Since there are many different test standards for digital TV display equipment in various countries around the world, and with the evolution of display equipment, the corresponding test standards are constantly changing and increasing. Several years of use are required, requiring test equipment that is compatible with changing test signal requirements and multiple different test standards. [0003] At present, the test signal equipment in the industry often uses an offline method to edit the digital TV tes...
