Question: The space-consuming analog video signal of a LaserDisc limited playback duration to 30 minutes (CAV) or 60 minutes (CLV) per side because of the hardware manufacturer's refusal to reduce line count for increased playtime. After one side was finished playing, a disc has to be flipped over in order to continue watching a movie, and some titles fill two or more discs. Many players, especially units built after the mid-1980s, can "flip" discs automatically by rotating the optical pickup to the other side of the disc, but this is accompanied by a pause in the movie during the side change. If the movie is longer than what could be stored on two sides of a single disc, manually swapping to a second disc is necessary at some point during the film. One exception to this rule is the Pioneer LD-W1, which features two disc platters. In addition, perfect still frames and random access to individual still frames is limited only to the more expensive CAV discs, which only had a playing time of approximately 30 minutes per side. In later years, Pioneer and other manufacturers overcame this limitation by incorporating a digital memory buffer, which "grabbed" a single frame from a CLV disc.
Is there an answer to this question: What must be reduced in order to allow LaserDisc playback time to increase?

Answer: line count


Question: Before mechanical printing, literature was copied by hand, and many variations were introduced by copyists. The age of printing made the scribal profession effectively redundant. Printed editions, while less susceptible to the proliferation of variations likely to arise during manual transmission, are nonetheless not immune to introducing variations from an author's autograph. Instead of a scribe miscopying his source, a compositor or a printing shop may read or typeset a work in a way that differs from the autograph. Since each scribe or printer commits different errors, reconstruction of the lost original is often aided by a selection of readings taken from many sources. An edited text that draws from multiple sources is said to be eclectic. In contrast to this approach, some textual critics prefer to identify the single best surviving text, and not to combine readings from multiple sources.
