text: The space-consuming analog video signal of a LaserDisc limited playback duration to 30/36 minutes (CAV NTSC/PAL) or 60/64 minutes (CLV NTSC/PAL) per side, because of the hardware manufacturer's refusal to reduce line count and bandwidth for increased playtime, (like what is done in VHS; VHS tapes have a 3 Mhz video bandwidth and a 333×480 pixels luma and 40×480 chroma resolution while LaserDisc preserves the full 6 Mhz bandwidth and resolution used in NTSC broadcasts).
