Design of H.264/AVC-based software decoder for mobile phone

Abstract

Investigations of the video service technology used for mobile phone have been actively performed recently. The efforts on the application of all the technologies available for commercialization of the framework of wire-internet into mobile environment have been also researched, thanks to the speedy development of a mobile phone and wireless network platform. The video service related technology based on the mobile phone has been implemented and operated on the basis of hardware. However, Current service mode, which is based on hardware, has its own disadvantage of not coping flexibly with various changes in the control structure of the new video codec algorithm and video data communication. Accordingly it is necessary to develop a decoder, which can deal with video service technology embodied in the form of hardware into that of software. This requires us to develop a new video player. In addition, such a decoder can achieve an immediate response due to further technology development including video data transmission and traffic control without consuming additional resources, in comparison with a hardware decoder chip technology. It can greatly contribute to an improvement in the manufacturing cost arising from incorporating an additional chip into mobile phones, as well as the reduction of resources through recycling. This paper designed a H.264/AVC video software-based decoder that uses component base design at the WIPI platform. © Springer-Verlag Berlin Heidelberg 2006.
