From a popular UK PC magazine:
"Each frame of TV may only have a fairly minimal 720x576 resolution, but with 25 frames every second the throughput required would be 20MB/s without compression".
"...the DV format has a standard data rate of 25MB/s, which equates to around 5:1 compression".
Can someone explain this to me? I assume they've confused Megabytes with Megabits?
