Aufzeichnung und Wiedergabe eines digitalen Videosignals |
摘要 |
<p>Reproducing heads (PB) reproduce signals from a tape (25) in advance of recording heads (REC) for a time period equivalent to a system delay. An ECC decoder (41) corrects an error of a signal received from each reproducing head. A BRR decoder (43) decompresses and decodes the signal received from the ECC decoder. A concealing circuit (45) interpolates the signal received from the BRR decoder. An output signal of the concealing circuit (45) is sent back to a selector (15) of the recording system (11-15, 18-24). The selector (15) switches between a signal received from an input terminal and the reproduced signal at the end of each field. An intra-field encoding process or an intraframe encoding process can be selected as a compressing and encoding process. Information that represents the selected encoding process is recorded on the tape (25). <IMAGE></p> |
