Patent ID: 8265151

Claim:
A method for encoding a video signal, comprising the steps of: (A) generating first sub-pel data used in at least one of (i) a motion estimation and (ii) a mode decision by first filtering reference data; (B) generating second sub-pel data used in a motion compensation by second filtering said reference data, wherein (i) a first performance of said first filtering is different than a second performance of said second filtering, (ii) said first filtering is not used in said motion compensation, (iii) said second filtering is not used in said at least one of said motion estimation and said mode decision, (iv) said second filtering utilizes at least six of a plurality of non-zero taps and (v) said first filtering utilizes less than six of said non-zero taps; and (C) compressing said video signal in response to said motion estimation, said mode decision and said motion compensation.
