چکیده

Algorithmically optimized AVC (MPEG-4 part 10 / H.264) video encoder with parallel processing of data is presented in the paper. The paper reveals the architecture of the proposed encoder together with the description of the applied software optimization techniques. Conducted experiments show exactly the degree of parallelization of computations in the encoder and the compression performance of video encoding.

Fpga Design for H.264/avc Encoder

In this paper, we describe an FPGA H.264/AVC encoder architecture performing at real-time. To reduce the critical path length and to increase throughput, the encoder uses a parallel and pipeline architecture and all modules have been optimized with respect the area cost. Our design is described in VHDL and synthesized to Altera Stratix III FPGA. The throughput of the FPGA architecture reaches a...

High Level Optimized Parallel Specification of a H.264/AVC Video Encoder

H.264/AVC (Advanced Video Codec) is a new video coding standard developed by a joint effort of the ITU-TVCEG and ISO/IEC MPEG. This standard provides higher coding efficiency relative to former standards at the expense of higher computational requirements. Implementing the H.264 video encoder for an embedded Systemon-Chip (SoC) is thus a big challenge. For an efficient implementation, we motiva...

GPU Acceleration of H.264 / MPEG-4 AVC Software Video Encoder

H.264 / MPEG-4 AVC encoding of high-resolution video is still a heavy task for today's high-end PCs. To accelerate the H.264 software encoder, we utilize many-core GPU (Graphics Processing Unit). Because spatial and temporal data dependencies between macroblocks (MBs) limit the MB-level parallel processing, we propose a relaxation method of inter-MB dependencies and a frame-pipelining to obtain...

Dynamic Data Partition Algorithm for a Parallel H.264 Encoder

The H.264/AVC standard is a highly efficient video codec providing high-quality videos at low bit-rates. As employing advanced techniques, the computational complexity has been increased. The complexity brings about the major problem in the implementation of a real-time encoder and decoder. Parallelism is the one of approaches which can be implemented by multi-core system. We analyze macroblock...
