H 264 Encoder Block Diagram

The next video frame to be compressed is denoted by fn.

H 264 encoder block diagram. Our baseline architecture will only support intraprediction since interprediction is considerably more complex. What is new in the h 264 encoder is the reconstruction path. Luma 4x4 hadamard chroma 2x2 hadamard. The frame is partitioned into macroblocks of 16 16 pixels each and each macroblock is encoded in intra or inter mode.

The main part of the encoder is its forward path. Dct like transform exact match inverse transform integer arithmetic only can be implemented using only 16 bit additions and bit shifting operations no multiplications dc coefficient. The block diagram for h 264 codec is shown in figure 1. Ec h264 8k kit soc web page.

The block diagram for the h 264 encoder using only intraprediction is shown in figure 1. The encoder figure 1 a includes two dataflow paths a forward path left to right shown in blue and a reconstruction path right to left shown in magenta. The three main building blocks are the dct quant and intra prediction blocks which will each be discussed below. Soc supplies plug and play evaluation kits for the h 264 8k encoder ip core.

The dataflow path in the decoder figure 1 b is shown from right to left to illustrate the similarities between encoder and decoder. The product code for 8k resolution encoder evaluation kit is.
