    This project, Portable Dual Mode Wireless & Broadcast Multimedia Platform, aims to research and develop a multi-standard compliant mobile digital TV platform that enables the receiving and viewing of broadcast mobile TV programs on the wireless network enabled portable devices, e.g. Portable Media Player (PMP) or mobile handset, by leveraging the convergence of wireless networks (cellular and Wi-Fi) and broadcast networks (DVB-H and T-DMB). Mobile TV is the most appropriate and profitable means of delivery high bandwidth usage multimedia contents due to its broadcasting in nature. Combined with mobile or Wi-Fi support, the platform provides a return path enabling interactive services. The project will address the challenges in the cost effective emerging mobile TV service delivery mechanism with the following major components: • Low power multimedia engine to achieve high quality content playback • Enhanced image signal processing algorithm for camera and LCD • Dual mode technology to support mobile TV and handset or Wi-Fi • Technology for improving usability and interoperability The technologies and product platform developed in this project include: • Multiple mobile TV and CODEC standards plus streaming over wireless network • Advanced image processing technology • Interactive service enabler • Usability and interoperability • Dynamic power management Phase 1 of this project will focus on dual mode technology and related multimedia engine for a mobile TV (T-DMB) and Wi-Fi platform.
