A universal television receiver

摘要

Various embodiments are described herein for a universal television receiver that is capable of processing television channel signals broadcast according to a variety of analog and digital broadcast standards including variations of NTSC, SECAM, PAL for analog signals and ATSC, DVB-T, ISDB-T for digital signals. The received multi-channel signal is filtered and amplified to produce a coarse channel signal. The coarse channels signal is digitized using a first sampling rate. Information for the desired channel signal is obtained from the digitized coarse channel signal. The digitized coarse channel signal is re-sampled at a second sampling rate to adjust a bandwidth of the desired channel signal.
