Abstract
A circuit for recovering the data encoded in several VBI channels without requiring a large number of gates. An analog to digital converter (ADC) and a clock and data recovery circuit may be associated with one of several possible channels. ADC over samples each VBI channel, and clock and data recovery circuit determines which subset of the over samples represent the encoded data by examining the over sampled samples. The selected subset may be stored in a shared memory and a equalizer may process the subset of samples of all channels to perform tasks such as deghosting. Due to the shared equalizer, the number of required gates may be minimized.
