Abstract:
1. A method, comprising: applying a reference filter to source video content to derive filtered source content; interlacing the source video content to derive interlaced content; de-interlacing the interlaced content with a test de-interlacer to derive test de-interlaced content; de-interlacing the interlaced content with a reference de-interlacer to derive reference de-interlaced content; deriving a test signal-to-noise ratio between the test de-interlaced content and the filtered source content; deriving a reference signal-to-noise ratio between the reference de-interlaced content and the filtered source content; and comparing the test signal-to-noise ratio and the reference signal-to-noise ratio with a predefined threshold to determine a level of quality of the test de-interlaced content.
