We designed a new live online lectures system called PPClass-M which is optimized for mobile scenario. It adopts an enhanced HTTP-streaming based streaming protocol which can elegantly handle the interim coverage outage and network switch commonly found in of mobile network as well as better support of the dynamic switch of consumed element streams needed to meet the resource constraints of smartphones. It also features a semi-3D based client GUI design which can deliver better user experience on smartphones with constrained screen size
