Digital signal recording apparatus and recording medium |
摘要 |
<p>The present invention provides a digital signal recording apparatus and a recording medium for recording digital compressed picture information on magnetic tape, and specifically the structure of the recording apparatus that suitably records picture trick-play data separately from recording data for a normal replay and the recording medium on which data is suitably recorded. <??>The digital signal recording apparatus includes picture data extraction circuit (103) for extracting picture data from the input digital compressed picture signal, trick-play-data generation means (105) for generating trick-play data while reducing the extracted picture data, and data disposition circuit (106) for disposing the trick-play data on tracks in position falling in line with the trace of the rotary magnetic head scanning in trick-play mode. The trick-play-data generation means (105) operates through program processing of a microprocessor (105). In addition, the recording apparatus generates trick-play data respectively applied to fast forward operation and rewind operation and record the data in predetermined locations on a medium, whereby faster display update on screen during the trick-play is achieved and rewind and replay operation can be performed suitably. <IMAGE></p> |
