H.264/AVC is the new video coding standard by ISO/IEC and ITU–T
doubling the coding efficiency of its ancestors in H.26x/MPEGx families.
This paper proposes a novel technique which remarkably reduces the
complexity of its innovative motion estimation (ME) system by configuring
at coding time the number of reference frames, valid block modes,
and search area used to perform the ME task for a given macroblock.
The optimal coding efficiency of H.264/AVC is kept unaltered in
a wide bit-rate range, from tens of kbits/s to tens of Mbits/s.
The proposed technique is applied to Full Search and Fast ME engines,
and both software and hardware implementations are discussed. |
