Abstract:
1. A system for picture resampling from a first resolution picture to a second resolution frame said system comprising: a) a position calculator for deriving a first resolution sample position corresponding to a sample position in a second resolution field; b) a data manager for managing filter data wherein said filter data is related to said first resolution sample position; c) a filter for filtering said first resolution picture based on said filter data thereby producing a filtered field; d) an opposite-parity position calculator for deriving an opposite-parity first resolution sample position corresponding to an opposite-parity sample position in an opposite-parity second resolution field; e) wherein said data manager is also capable of managing opposite-parity filter data wherein said opposite-parity filter data is related to said opposite-parity first resolution sample position; and f) an opposite-parity filter for filtering a first resolution opposite-parity field based on said filter data thereby producing an opposite-parity filtered field.
