hdtv built in video encoders directly support ntsc and progressive 480 p video outputs these two video formats have different image bandwidth and output gain requirements but are normally filtered by fixed bandwidth filters this invention provides adjustable filter bandwidth for improved video filtering and solves the dilemma on filter bandwidth design for multi format video applications the invention is applicable to video reconstruction filter applications requiring bandwidth adjustable filters application_number US 23493408 A description a filter design of fixed frequency response and gain meets only one video format requirement some designs have previously used simple filters with wider bandwidth to provide filtering for progressive video and passed sdtv with little or no filtering the present invention is a filter providing adjustable filter bandwidth and gain control at nominal cost and power consumption fig1 illustrates the bandwidth requirements for digital media processors supporting multi format video the video processor input channel 100 supplies luminance component 102 and chrominance components 103 and 104 to the three respective filter networks 105 106 and 107 when video processor input channel 100 outputs sdtv 108 the filters 105 106 and 107 use a cutoff frequency fc 6 25 mhz when video processor input channel 100 outputs progressive scan 480 p in rgb format filters 105 106 and 107 use a cutoff frequency fc 12 5 mhz for the y u2014 pr u2014 pb format filter 105 for the y component uses a cutoff frequency fc 12 5 mhz while filter 106.
