Accelerating Software-based Mpeg Encoding Using the Vis Tm Instruction Set
MPEG is a set of standards for the compression and coding of digital audio and video signals. In order to provide high compression ratios without loss of quality, MPEG encoders perform complex analyses on source material. These analyses require billions of operations to encode even a short sequence of video lasting only seconds. Even the fastest general-purpose microprocessors available today l...
متن کاملA novel architecture for parallel multi-view HEVC decoder on mobile device
The multi-view HEVC (MV-HEVC) extension was finalized in July of 2014 by the Moving Picture Experts Group and the Video Coding Experts Group. Recently, multi-view videos based on stereo representations are becoming widely popular. Also, a variety of multimedia contents are now available for mobile devices. A real-time multi-view video decoder is therefore needed. In mobile devices, a real-time ...
متن کاملAdaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملSampling Based Model Predictive Control with Application to Autonomous Vehicle Guidance
Model Predictive Control (MPC) was originally developed for relatively slow processes in the petroleum and chemical industries and is well known to have difficulties in computing control inputs in real time for processes with fast dynamics. In this paper a novel method called Sampling Based Model Predictive Control (SBMPC) is proposed as a resolution complete MPC algorithm to generate control i...
متن کاملAn Adaptive Video Coding Control Scheme for Real-Time MPEG Applications
This paper proposes a new rate control scheme to increase the coding efficiency for MPEG systems. Instead of using a static group of picture (GOP) structure, we present an adaptive GOP structure that uses more Pand B-frame coding, while the temporal correlation among the video frames maintains high. When there is a scene change, we immediately insert intramode coding to reduce the prediction er...
