Apparatus and method for inter and intra mode selection and block partitioning

摘要

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.

1. A hardware video encoder, comprising:
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, wherein 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 to produce pairs of motion vectors and rate-distortion values for different block sizes, wherein the pairs of motion vectors and rate-distortion values for the different block sizes are computed in parallel; and a selection block to initially process the pairs of intra prediction mode indices and rate-distortion values and then process the pairs of motion vectors and rate-distortion values and then process split values, where the selection block selects the lowest value among the pairs of intra prediction mode indices and rate-distortion values, the pairs of motion vectors and rate-distortion values and the split values.
