Motion estimation based on rate distortion criteria

Introduced: January 2014

Full Title

Full titles differ between systems:

IPC:

Methods or arrangements for coding, decoding, compressing or decompressing digital video signals > using predictive coding > involving temporal prediction > Motion estimation or motion compensation > Motion estimation based on rate distortion criteria

CPC:

Methods or arrangements for coding, decoding, compressing or decompressing digital video signals > using predictive coding (H04N19/61 takes precedence) > involving temporal prediction (adaptive coding with adaptive selection between spatial and temporal predictive coding H04N19/107; adaptive coding with adaptive selection among a plurality of temporal predictive coding modes H04N19/109) > Motion estimation or motion compensation > Motion estimation based on rate distortion criteria

No child classifications to compare. This is a leaf node in both IPC and CPC.
