ABSTRACT:
A time-base conversion system including a first clock generator for generating a read clock based on a reference signal, a second clock generator for generating a write clock by dividing the read clock, a memory, a circuit for writing video data in the memory based on the write clock, a circuit for reading the video data recorded in the memory based on the read clock, and a time-base compressor for determining a compression ratio of the video data time-base by determining a division ratio of the write clock.
