Flexible Macroblock Ordering or FMO is one of several error resilience tools defined in the Baseline profile of the H.264/MPEG-4 AVC video compression...

DVD for each macroblock being compressed. Sometimes no suitable match is found. Then, the macroblock is treated like an I-frame macroblock. MPEG-2 video...

A Block Matching Algorithm is a way of locating matching macroblocks in a sequence of digital video frames for the purposes of motion estimation. The...

blocks are grouped into macroblocks of 16 × 16 samples, and the 16 DC coefficients from the 4 × 4 blocks of each macroblock are passed through another...

restructuring the ordering of the representation of the fundamental regions (macroblocks) in pictures. This type of algorithm avoids the need to wait for a full...

Each motion vector is used to represent a macroblock in a picture based on the position of this macroblock (or a similar one) in another picture, called...
