METHOD FOR GENERATING TEST PATTERNS FOR DETECTING AND QUANTIFYING LOSSES IN VIDEO EQUIPMENT

摘要

A method for detecting and quantifying losses in at least one of video and audio equipment, comprising the steps of generating the test pattern; processing the test pattern through video equipment; and displaying the processed test pattern to a display to a viewer. In one embodiment, the test pattern is indicative of video compression losses due to quantization. In another embodiment, the test pattern is indicative of a color transformation mismatch after encoding/decoding with incompatible video transmission standards. In a third embodiment, the test pattern is iso-luminant after a color transformation between a first and second video transmission standard. In a fourth embodiment, the test pattern is indicative of lipsync error.

1. A method for detecting and quantifying losses in video equipment, comprising the steps of:
generating a test pattern, the test pattern comprising at least two colors, wherein when a color transformation mismatch occurs due to processing with incompatible video transmission standards, a resulting pattern displays a reduction in contrast between the at least two colors; processing the test pattern through video equipment; and displaying the processed test pattern on a display to a viewer.
