Please Note That This Submission Is Intended Specifically for the Special Issue on Low Power Electronics and Design Trading Dct/idct Quality for Energy Reduction in Mpeg-2 Video Codecs
It would be desirable, in terms of energy conservation, to use one low complexity, approximate algorithm to do all discrete cosine transform (DCT) and inverse discrete cosine transform (IDCT) computation in an MPEG-2 video codec. However, there is a significant quality penalty associated with this approach that may not always be acceptable. A technique that applies both exact and approximate DC...
متن کاملContext-Aware Fast 3D DCT/IDCT Algorithm for Low- power Video Codec in Mobile Embedded Systems
A context-aware fast algorithm for 3D DCT/ IDCT video coding is presented in the paper. Compared to state-of-art MPEGx/H.26x hybrid schemes the new algorithm is suited for low-power video codec in mobile embedded systems. 1. 3D DCT for Low-power Video Codecs The 2D-DCT is a powerful tool for reducing the spatial information redundancy in 2D images: intraframe coding of still images and videos i...
متن کاملAn approach for enabling DCT/IDCT energy reduction scalability in MPEG-2 video codecs
It would be desirable, in terms of energy conservation, to use a low complexity approximate algorithm to do all DCT and IDCT computation in an MPEG-2 video codec. However, there is a significant quality penalty associated with this approach that may not always be acceptable. A practical algorithmic method is studied here for achieving scalable energy reduction during DCT and IDCT computation in...
متن کاملA simple processor core design for DCT/IDCT
This paper presents a cost-effective processor core design that features the simplest hardware and is suitable for discrete cosine transform/indiscrete cosine transform (DCT/IDCT) operations in H.263 and digital camera. This design combines the techniques of fast direct two-dimensional DCT algorithm, the bit-level adder-based distributed arithmetic, and common subexpression sharing to reduce th...
متن کاملA Full-Fuzzy Rate Controller for Variable Bit Rate Video
In this paper, we propose a new full-fuzzy video ratecontrol algorithm (RCA) for variable bit rate (VBR) videoapplications. The proposed RCA provides high qualitycompressed video with a low degree computational complexity.By controlling the quantization parameter (QP) on a picturebasis, it produces VBR video bit streams. The proposed RCAhas been implemented on the JM H.264/AVC video codec andth...
