METHOD AND DEVICE FOR REDUCING A PERCEIVED DISCONTINUITY IN A CONTINUOUS DIGITAL INFORMATION STREAM

摘要

A method and a device are disclosed for reducing a perceived discontinuity in a continuous digital information stream read back from a first (LO) and a second (L1) layer of a multi-layer record carrier (104), said discontinuity occurring during the transition from the first (LO) to the second (L1) layer. The method comprises the steps of monitoring (S1) said digital information stream to be recorded on said multi-layer record carrier (104), determining (S2) a time (ti) corresponding to a point in said digital information stream where an effect of a perceived discontinuity is reduced, and recording (S3) said digital information stream such that a transition from recording on the first layer (LO) to recording on the second layer (L1) of the multi-layer record carrier (104) occurs at said determined time (ti), thereby reducing perceived discontinuity that occurs in, for example, a read back device with a relatively small data buffer. Furthermore, it provides for the possibilities to reduce the data buffer size and relax the time constraints on the active components used during read back in a device arranged for read back of a multi-layer record carrier.
