VIDEO SYSTEM FOR DISPLAYING LOWER RESOLUTION VIDEO SIGNALS ON HIGHER RESOLUTION VIDEO MONITORS

摘要

Lower resolution video signals (10) having alternating odd fields (12) and even fields (14) are stored in an odd line memory (20A) and an even line (20B), respectively. An interpolator (22) interpolates adjacent odd and even lines. A selector (24) cyclically selects odd, even, and interpolated lines in a pre-selected pattern. By selecting even, odd, and interpolated lines, the number of lines per picture is increased to produce a higher resolution video signal (30).
