Vorrichtung zum Aufnehmen und Wiedergeben von digitalen Videosignalen

摘要

An apparatus for recording/playback digital data with variable length codes which are encoded from intra-frame compression data and inter-frame compression data. The apparatus include a data rearranging circuit for rearranging the intra-frame compression data in the variable length encoded data and an address and a data length adding circuit for adding addresses and data length information of the intra-frame compression data output from the data rearrangement means. Furthermore, a device for setting an error flag in case of non-correctable errors is included, which generates zero data to replace erroneous encoded data. A second set of special video heads is provided for a variable speed replay. According to the error rate, either the signal derived from the ordinary heads or the signal from the special heads is processed by the decoder.
