Patent ID: 8498338

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) said first filtering utilizes a first number of a plurality of non-zero taps, (ii) said second filtering utilizes a second number of said non-zero taps and (iii) said first number is less than said second number; (C) generating third sub-pel data used in said mode decision by third filtering of said reference data, wherein a performance of said third filtering is different than both said first filtering and said second filtering, wherein said first filtering, said second filtering and said third filtering are performed in parallel; and (D) compressing said video signal by inter-coding based on said motion estimation.
