AI Technical Summary

Benefits of technology

This technology allows for accurate decoding of signals from analog or digitally recorded media without any errors caused by lack of sync between different devices involved during transmission. It also ensures consistently high quality measurements over time due to its ability to measure changes in gray levels continuously across multiple channels at once.

Problems solved by technology

Technological Problem addressed in this patented technical solution describes how accurately determining the geometric characteristics of a displayed picture called a curved look pattern (CGM), such as chromaticity and contrast ratio, allows for precise control over these parameters during playback without any discomfort experienced from manually controling multiple settings.

Embodiment Construction

[0020] Embodiments of the present invention provide a signal measurement method and system for measuring a color-scale audio-visual stream (signal to be tested) in digital broadcasting to obtain its corresponding color-level curve. According to an embodiment of the present invention, before transmitting a signal under test having a plurality of color-level signals, a color-level signal with a specific brightness is inserted to generate a composite signal stream, wherein a first color-level signal among the color-level signals The brightness is different from the brightness of the color scale signal with a specific brightness by a predetermined value. Therefore, when receiving the synthesized signal stream, according to the difference of the detected signal value, the first color in the said color scale signal in the signal to be tested in the synthesized signal stream can be found in the mode of high-speed measurement. Level signal (for example, the 0th level signal or the 255th

Abstract

The present invention provides a signal measurement method, comprising the following steps of firstly, receiving a resultant signal stream; secondly, detecting the resultant signal stream at a first time point to obtain a first signal value; thirdly, determining the implementation of a color gradation curve measurement for the resultant signal stream according to the first signal value. According the signal measurement method and the system, the instance that the measurement result is not correct because the measurement command and the color gradation video streaming can not be synchronous can be avoided, and the influence due to the delay problem is overcome.
