Video Coding Strategy using Multiple Codec towards ERD Optimization

Duration: May - July 2013

Status: Completed

Members: Pranav Sodhani, Dr. Chong-Min Kyung

Note: The project was carried out during the summer break after my sophomore year. This 9-weeks long internship at the Smart Sensor Architecture Lab, KAIST was funded by the Global Frontier Project.

Overview

The goal of the project is to determine and suggest the best encoder configuration and the codec (H.264/AVC or H.265/HEVC) to be used for the given input video sequence in order to optimize Energy Consumption, Bit-rate and Distortion. Various encoder parameters like Search range, Intra-Period and Quantization parameter are varied to determine the most suitable configuration as per the constraints and the objectives to be fulfilled. Benchmark video sequences with different degrees of motion complexity and diverse resolution are employed to compare coding efficiency of H.264 and its natural successor H.265. Mathematical relations and graphical plots between the monitoring parameters (Y-PSNR, Bit-rate and Power (time)) and the control parameters (Search Range, Intra-Period and Quantization parameter) are evaluated to attain the required solution.
