Complexity and memory reduction for high-quality interlace video coding in H.264/AVC

We propose two techniques for an H.264/AVC hardware encoder, maximum three reference fields selection and restriction of the number of MC size based on picture coding type. The proposed method can reduce complexity by more than 40% and the amount of memory by 25% without visual degradation.

Study on adaptive reference picture selection in H.264/AVC interlaced coding

We propose a reference picture selection scheme in H.264/AVC interlaced coding. Only two reference fields for one B-field are adaptively selected depending on the scene characteristics. The proposed method provides 10% coding efficiency gain over non-adaptive selection methods with the same number of reference pictures.
