Digital signal processing apparatus for recording and reproducing time-base compressed digital image data in an image transmission system |
摘要 |
Time-based compressed data representing a program is supplied from a local conditional access circuit to two recording signal processing circuits which supply the data to be recorded simultaneously in time-compressed form by a digital VTR and an HDD (hard disc drive). The HDD need only store enough data to allow the digital VTR to record the entire program and to synchronize the output of the VTR with the output of the HDD. Once the program has been recorded on the VTR, it is reproduced therefrom concurrently with the portion of the program reproduced by the HDD and, once synchronization therebetween is reached, the VTR-reproduced data replaces the HDD-reproduced data. The reproduced data is supplied to an MPEG decoder circuit to be output as a reconstructed program for immediate display.
