The lifting-based wavelet transform apparatus includes: a prediction unit which performs bi-directional motion compensation on odd-indexed frames based on even-indexed frames and generates high-frequency frames using differential frames from which most of energy is removed; an update determination unit which, in the even-indexed frame, determines whether to update each target block at which a reference block indicated by a motion vector is placed; and an update unit which updates a target block of the even-indexed frame which is determined to be updated by adding the differential frame to each target sub-block included in the target block and generates low-frequency frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wavelet transform apparatus and method, scalable video coding apparatus and method employing the same, and scalable video decoding apparatus and method thereof","description":"Provided are a lift-based wavelet transform apparatus and method, a scalable video coding apparatus and method using the same, and a scalable video decoding apparatus and method.
