Intra Prediction for the Hardware H.264/AVC High Profile Encoder
The hardware implementation of the intra prediction described in this paper allows the H.264/AVC encoder to achieve optimal compression efficiency in real-time conditions. The architecture has some features that distinguish it from other solutions described in literature. Firstly, the architecture supports all intra prediction modes defined in High Profile of the H.264/AVC standard for all chro...

متن کاملAn Efficient Intra Prediction Algorithm for H.264/AVC High Profile
A simple, highly efficient intra prediction algorithm to reduce the computational complexity of H.264/AVC High Profile is proposed. The algorithm combines two methods. The first method is a quant-based block-size selection decision that is based on the sum of the quantization AC coefficients among intra 8 × 8 mode predictions, combined with an error adjustment to select either intra 4 × 4 or in...
متن کاملA Novel Fast Block Type Decision Algorithm for Intra Prediction in H.264/AVC High Profile
The latest video coding standard H.264/AVC significantly increases video compression efficiency but also increases computation complexity. Intra prediction is an important part in H.264/AVC encoder and it’s also time consuming. This paper proposes a fast block type decision algorithm which can reduce intra prediction’s computation complexity with slight PSNR reduction. The relation between intr...
متن کاملFast Intra Mode Decision Algorithm for H264/AVC HD Baseline Profile Encoder
The high performance of H.264/AVC video encoder is accompanied with a wide computation complexity especially for high definition (HD) video sequences. One of the major H.264/AVC features to be optimized is the mode decision for both inter and intra prediction. Thus, based on high correlation observed between selected inter prediction mode and intra mode decision, a fast intra mode decision algo...
