This system consists of 3-D laser video disc player, 120 Hz vertical frequency monitor and liquid crystal glasses. The 3-D video signal, left and right eye's video fields being time multiplexed alternatively, is time compressed to double fields of NTSC to 120/sec, 60 for right eye and 60 for left eye, above threshold of flicker. On the other hand, the video signal uses 4:1 interface to gain higher resolution, so that each frame has 524.5 scanning lines for each eye. Both sides of CLV disc play 60 minutes.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M00526.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "AV Laboratory SANYO Electric Co., Ltd.
