Patent ID: 7643384

Claim:
A method for controlling a pick-up for reading three or more out-of-multiplex data streams from a storage medium, the data streams being used for simultaneous reproduction and belonging to different data types with different constant or variable data rates, and the data streams being distributed to more than one file on said storage medium and being separately buffered after reading, wherein the pick-up data rate is higher than any of the buffer output data rates, with the amount of buffered data relating to any of said data streams being at least such that subsequent processing can be provided with the buffered data during the time required for accessing and reading the other data streams of the other data types, the method comprising: buffering a first data stream of a first data type, the data stream having the highest buffer output data rate of all said three or more buffered data streams, wherein said first data stream is read and buffered periodically in periods of a first period time; and accessing the data streams by the pick-up according to a predefined temporal scheme, the scheme being such that, after an Initialization, for any three successive data stream accesses, wherein the second access reads another than said first data stream, the first and last accesses read said first data stream, and wherein the data streams other than said first data stream are accessed and buffered in a constant predetermined order in periods of integer multiples of said first period time, the integer being two or more.
