Abstract
A hardware video encoder includes an intra search block operating on a source picture to produce pairs of intra prediction mode indices and rate-distortion values for different block sizes. The pairs of intra prediction mode indices and rate-distortion values for the different block sizes are computed in parallel based upon the source picture. An inter search block produces pairs of motion vectors and rate-distortion values for different block sizes. The pairs of motion vectors and rate-distortion values for the different block sizes are computed in parallel.
