Traditional learning activity has inherently restricted by time and space. New learning paradigms, such as M-learning becomes an irreplaceable learning tool because learner is not confined in the restricted environment. Such a new learning system benefits students in cases of lifelong learners and new influenza. Moreover, several new wireless communication technologies are developed and deployed for marketing needs. For examples, mobile cellular network such as WCDMA, WiMAX and LTE; and WLAN such as IEEE 802.11b/g/n. These technologies are formed different access networks and used to connect to internet easily anytime and anywhere with any available portable devices such as PDA, laptop, netbook and smart phone. Meanwhile, several emerging applications are applied in M-Learning such as Short Message Service, Multimedia Messaging Service, Location Based Service and broadcasting service such as IPTV. IPTV is a broadcasting TV service based on Internet Protocol. Traditional TV services are very popular in house, school or company. But it is a one-direction TV service without interaction. The IPTV services possess a main feature of bi-direction connection that can provide interactive TV services such as voting service, TV shopping and interactive instruction. Personal Video Recorder (PVR) is one of important IPTV services. PVR stores video content from broadcast TV and replays it at any convenient time. The IPTV PVR service can be used to product interactive multimedia teaching materials. Therefore, this study proposes a framework of novel learning environment: A scaffolding M-learning framework with IMS based IPTV PVR service. In this framework based on IMS, access networks which supported by IMS can be integrated into core IMS network and then services can be inter-operated between different access networks. With an adaptive scaffold, learners study independently, handle any situation they encounter, increase learning efficiency and achieve seamless learning space. Furthermore, teacher's precious knowledge and experiences are gathered, preserved and passed down completely.
