I want to know the answer to the following question:
What must be reduced in order to allow LaserDisc playback time to increase?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
