Abstract
A data recorder for a digital video disc includes a first-in, first-out buffer memory. The memory is responsive to an input data signal for sequentially storing in a first-in, first-out manner a running, data of Video Object Units (VOBU's), defined in the Digital Versatile Disc (DVD) Specification for Read Only Disc (the specification), prior to recording the data. In a first embodiment of the invention, the values of each address pointer of a first sub-set of address pointers contained in a field VOBU Search Information (VOBU_SRI), are established in accordance with the VOBU's contained in the buffer memory. The value of each address pointer of a second sub-set of the address pointers, associated with VOBU's positioned further behind, in a sequence of presentation, than each of the VOBU's contained in the memory is not made to conform to the Specification. Thereby, a storage capacity requirement from the buffer memory is reduced. In a second embodiment of the invention, the size of each Cell in the data format is constrained to only 59 VOBU's. The entries for each address pointer of the second sub-set, is made to contain a 'does not exist' code.
