Efficient HEVC to H.264/AVC Transcoding with Fast Intra Mode Decision
High Efficiency Video Coding (HEVC) standard will soon reach its final draft. To provide the widely deployed H.264/AVC devices with HEVC video contents, transcoding pre-encoded HEVC video into H.264/AVC format is highly necessary. Computational complexity of H.264 hinders real-time transcoding. In this paper, we propose an efficient HEVC to H.264 intra frame transcoder to accelerate the time-co...
متن کاملA Fast Block Size Decision For Intra Coding in HEVC Standard
Intra coding in High efficiency video coding (HEVC) can significantly improve the compression efficiency using 35 intra-prediction modes for 2N×2N (N is an integer number ranging from six to two) luma blocks. To find the luma block with the minimum rate-distortion, it must perform 11932 different rate-distortion cost calculations. Although this approach improves coding efficiency compared to th...

متن کاملSubjective Evaluation of Hevc Intra Coding for Still Image Compression
High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video frames. Hence, it is natural to question how such intra coding compares to state of the art compression codecs for still images. This paper ...
متن کاملComparison of High Efficiency Video Coding (hevc) Performance with H.264 Advanced Video Coding (avc)
High Efficient video coding (HEVC) will be replacing the current standard, H.264/MPEG-4 Advanced Video Coding (AVC). The main goal for HEVC standardization is to deliver equal video quality for half the bit-rate of H.264/MPEG-4 AVC. Other objective of HEVC is to support higher resolution than the current high definition (HD) of 1920 × 1080. Nevertheless, HEVC standard has similar structure desi...
