Digital component video signal processor for two data rates. |
摘要 |
<p>A digital component video signal processor or a digital VTR is disclosed which can record/reproduce both an extended 4:2:2 signal based on sampling at 18 MHz and a 4:2:2 signal based on sampling at 13.5 MHz while minimizing dummy data to be generated upon recoding/reproduction. The extended 4:2:2 signal and the 4:2:2 signal are changed over by switches (5, 28, 29), and the output side of memories (8, 10, 34, 36) uses timing signals based on a clock signal of 36 MHz whereas timing signals based on the clock signal of 36 MHz and timing signals based on a clock signal of 27 MHz are changed over by a switch (46) on the input side of the memories, whereby each of an extended 4:2:2 signal and a 4:2:2 signal at a rate of 288 Mbits/sec can be outputted to a terminal (39). <IMAGE></p> |
