Abstract:
A moving picture data compression device for compressing moving picture data read from a recording medium recorded with moving picture data, comprising:non-realtime data receiving means for reading moving picture data from a non-realtime data recording medium, which is recorded with moving picture data that is capable of being read unrelated to the passage of time; synchronization signal generating means for generating a synchronization signal based on moving picture data received by the non-realtime data receiving means; realtime data receiving means for reading moving picture data from a realtime data recording medium, which is recorded with moving picture data capable of being read sequentially according to the actual passage of time; additional synchronization signal generating means for generating a synchronization signal according to a receiving operation by the realtime data receiving means; and compressing means for selectively executing either non-realtime data compression operations for compressing moving picture data received by the non-realtime data receiving means according to the synchronization signal generated by the synchronization signal generating means or realtime data compression operations for compressing moving picture data received by the realtime data receiving means according to the synchronization signal generated by the additional synchronization signal generating means.
