In this paper, we propose an implementation method of personal digital recorder for HDTV. The proposed personal recorder includes CPU and system control modules, graphics and display module, audio DSP module, digital I/O module, NIM module, graphic software library, and embedded software modules for providing a lot of personal digital recorder functions such as live or reserved recordings, browsing of recorder content list, trick lay and time shifting. Especially, combining trick play with time shifting makes much more convenient functions such as pausing live TV, instant replay of interesting scenes, and skipping advertising.
