Abstract
A video decoder is provided. An analog-to-digital converter (ADC) converts an analog video signal into a plurality of samples at a sampling rate. A main processing path collects a plurality of odd samples to provide a first decoded video output and synchronization information. A plurality of even samples is converted into a plurality of first converted samples at a first predetermined frequency by a sample rate converter, and then filtered by a filter to obtain a second Y signal. A buffer stores the second Y signal, and reads the second Y signal in response to the timing information. An output sample rate converter converts the buffered output into a plurality of second converted samples at a second predetermined frequency. A parallel-to-serial converter receives the first decoded video output and the plurality of second converted samples to drive a second decoded video output.
