چکیده

A novel priority-based heading one detector for Exp-Golomb/CAVLC decoding of H.264/AVC is presented. It exploits the statistical distribution of input encoded codewords and adopts a nonuniform partition decoding scheme for the detector. Compared with a conventional design without power optimization, the power consumption can be reduced by more than 3 times while the performance is maintained and the design hardware cost does not increase. The proposed detector has successfully been verified and implemented in a complete H.264/AVC decoding system.

Complexity modeling for context-based adaptive binary arithmetic coding (CABAC) in H.264/AVC decoder

One way to save the power consumption in the H.264 decoder is for the H.264 encoder to generate decoderfriendly bit streams. By following this idea, a decoding complexity model of context-based adaptive binary arithmetic coding (CABAC) for H.264/AVC is investigated in this research. Since different coding modes will have an impact on the number of quantized transformed coefficients (QTCs) and m...

High Speed Decoding of Entropy Codes in H.264/AVC Based on a Symbol Prediction

H.264/AVC is adopted as a next generation moving picture compression standard. Context-based Adaptive Binary Arithmetic Coding (CABAC) is the major entropy coding algorithm employed in H.264/AVC. Although the performance gain of H.264/AVC is mostly resulted from CABAC, it is difficult to implement a high-throughput decoder due to its decoding complexity. Although CABAC excludes a multiplication...

Memory Analysis for H.264/AVC Scalable Extension Decoder

In this paper, a systematic analysis for memory usage in H.264/AVC scalable extension (SVC) decoder is presented. This paper analyzes the memory requirements with three different decoding flows, macroblock, row and frame based, to find out a best method which can achieve optimal trade-off between internal memory usage and external memory access. The analysis shows that the SVC decoding needs 88...

Video Abstraction in H.264/AVC Compressed Domain

Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...

Pipelining Architecture Design of the H.264/AVC [email protected] Codec For HD Applications

This paper presents the macroblock/slice level pipeline structure for an H.264/AVC [email protected] codec. In H.264/AVC, level 4.2 (L4.2) in high profile (HP) describes the encoding/decoding capability of 1920x1088@64p sequence/ bitstream of up to 62.5 Mbps. To meet this tremendous specification, the novel hardwired architecture of the H.264/AVC codec is also presented. It supports both encoding and dec...
