METHOD AND DEVICE FOR MOTION VECTOR ESTIMATION IN VIDEO TRANSCODING USING FULL-RESOLUTION RESIDUALS |
摘要 |
A transcoder and method of transcoding in which inter-prediction frames of a downsampled video are encoded using downsampled full-resolution residuals DS(U i) in the rate-distortion analysis used to locate a motion vector .nu.i for a given partition in the downsampled video.
