چکیده
This paper illustrates a real-time implementation of MPEG-2 (BC) layer 1 and layer 2 stereo encoder on a Pentium-III platform. It describes the architecture and features of Pentium-III, suited for real-time implementation of stereo encoder. Further, the MPEG audio encoder algorithm and techniques used in optimizing the individual modules for Pentium-III environment are explained. Finally, the paper discusses the performance results of this implementation with regards to quality of the output signal as well as CPU utilization.

High-quality and processor-efficient implementation of an MPEG-2 AAC encoder
Presented here is MPEG-2 AAC LC Profile encoder software for an Intel Pentium III processor. MDCT and quantization processing are accelerated by the use of SIMD instructions. Psycho-acoustic analysis in the MDCT domain makes the use of FFTs unnecessary. Better sound quality is provided by greater efficiency in quantization processing and Huffman coding. All of this results in high-quality and p...

متن کاملRedundant codes in hybrid networks
Hybrid networks consisting of satellite links and mobile ad hoc networks present a series of challenges due to different packet-loss patterns, delay, and, usually, scarce available bandwidth. In this scenario, redundant encoding, in the form of Forward Erasure Correction (FZC) codes [1],[2], can provide an effective protection against losses in multicast videoconferencing and video streaming ap...
