Project: H.264 to MPEG-2 Video Transcoder for Digital TV

Acronym: H2M
Main Objective: The main goal of this project is to develop a real-time H.264 to MPEG-2 software transcoder for video adaptation in Digital Television (DTV) services. On the one hand, the latest international video coding standard, ITU.T H.264, achieves high coding efficiency by employing advanced techniques such as variable block size motion estimation, optimised R-D mode decision, intra prediction, and multiple reference frames. On the other hand, MPEG-2 is the most common video standard adopted by the multimedia industry, where it finds a broad range of applications in digital TV, DVD, etc. Due to the higher coding efficiency of H.264, it is expected that this new standard will replace MPEG-2 compression in digital video systems. However, the complete migration is expected to take several years, given the wide use of MPEG-2 based equipments in the market place today. Therefore the type of format conversion developed in this project has significant potential impact.
