Abstract (en)
[origin: WO2005081519A1] A television (TV) receiver includes a multi-standard channel filter (58) with a programmable intermediate frequency adapted to receive television signals in a variety of television standards and formats. In one embodiment, a receiver includes a tuner (54) and a channel filter. The tuner receives input RF signals encoding information in one of a number of formats and converts the input RF signals to intermediate signals having an intermediate frequency (IF). The intermediate signals are coupled to the channel filter. The channel filter includes an anti-aliasing filter (60) for filtering the intermediate signals, an analog-to-digital converter for (62) sampling the filtered intermediate signals and generating a digital representation thereof, and a signal processor (64) for processing the digital representation of the intermediate signals in accordance with the format of the input RF signal. The signal processor generates digital output signals indicative of information encoded in the input RF signal.
