Abstract: This memorandum compares subjective video quality test results from a professional cathode ray tube (CRT) television monitor with that of a consumer liquid crystal display (LCD) video phone monitor. The CRT monitor supported the full ITU–R Recommendation BT.601 resolution (720 x 486) while the LCD monitor only supported Common Intermediate Format (CIF) resolution (352 x 288). The subjective results from the two tests are very similar, with the only significant difference being that the CIF monitor masks impairments that appear in only one of the two interlaced fields.

Keywords: video quality; image quality; subjective testing; CIF; ITU-R Recommendation BT.601; monitor resolution
