Motion adaptive deinterlacer with integrated dynamic format change filter
View Patent ↗A system and method that scales interlaced video fields with different sizes in a deinterlacer. The deinterlacer may expect video fields of a certain size. The input to the system may be a video stream of interlaced content, with fields having different sizes depending on the video content. The method scales the input video fields to the appropriate size expected by the deinterlacer. The expected size of the fields may be programmable. The method may provide an output with the expected size of black pixels in the absence of an input to the system.
1. A system for deinterlacing video fields, said system comprising:
an input for receiving a first plurality of interlaced fields with at least two different sizes and a second plurality of interlaced fields with at least two different sizes; and
a circuit for deinterlacing the first plurality of interlaced fields with the at least two different sizes, thereby resulting in progressive frames, wherein said progressive frames have a first size and deinterlacing the second plurality of interlaced fields with at least two different sizes, thereby resulting in other progressive frames having a second size.
2. The system of claim 1 , wherein the circuit comprises a filter.
3. The system of claim 2 , wherein the filter comprises a polyphase scaler.
4. The system of claim 1 , wherein the plurality of sizes comprises a plurality of horizontal sizes.
5. The system of claim 1 , wherein the plurality of sizes comprises a plurality of vertical sizes.
