Abstract: A terminal device determines whether a clock is a secure clock or a self-running clock. If the clock is the self-running clock, the device stores a clocking time of the clock as a timestamp file in a memory card in recording content. In playing back the content, the device determines validity of a clocking time using the timestamp file to play back the content and also updates the stored time of the stored time as the timestamp file to a content playback start time. In contrast, if the clock is the secure clock, the device stores the timestamp file indicating a recording time of the content in the memory card only in recording the content and omits updating the stored time as the timestamp file in playing back the content.

Abstract: Movies are produced in 24 Hz frame frequency and progressive scanning format (denoted 24p) for projection in film theatres, adhering to a worldwide standard for 35 mm film. However, the major TV systems in the world use interlaced scanning and either 50 Hz field frequency (denoted 50i) or 60 Hz field frequency (denoted 60i). Content providers would prefer providing single-picture-frequency single-audio-speed AV discs that can be replayed in most parts of the world. A 24p audio/video data stream is supplemented with additional 50i format data items thereby allowing 24p and 50i format replay of that data stream.
