Abstract:
A method for transferring data from a DVD medium to a host, comprising the steps of:receiving, at a DVD interface, a request for a data block set issued from a host, wherein the requested data block set has an associated target data block ID and data block number; obtaining the requested data block set from a DVD medium; and transferring the data the host; wherein the obtaining is performed by a controller, which is within the DVD interface, by: retrieving a stream of data blocks, from the DVD medium, each retrieved data block having an associated data block ID; comparing the data block IDs of the retrieved data blocks until a match is found with the target block ID, using a comparator circuit associated with the controller; starting with the data block whose data block ID matches the target block ID, storing the retrieved data blocks into a buffer; and stopping the storing of data blocks into the buffer when a count of the stored data blocks matches the data block number.
