Advanced PVR Architecture with Segment-based Time-Shift

Though the benefits of personal video recorders (PVRs) with high performance cpu and large storages, consumers are navigating live contents time-independently as time-shift. In this paper, we proposed an advanced PVR architecture which has general PVR functions as well as metadata functions. A new video indexing method, known as segment-based time shift algorithm is introduced. To take full advantage of such algorithm, we also develop a PVR set-top-box (STB) with efficient GUI interface.
