<p>An apparatus is disclosed for reproducing a disc, such as an optical disc, having main digital data, such as video data, stored thereon in successive blocks associated with sub-digital data for searching. Each of said blocks comprises a header signal and a block address signal followed by the main digital data. Means are provided for searching the main digital data using the sub-digital data, for detecting the header signal, for detecting whether the block address is the required one, and for deriving the the required main digital data.</p> |
