Document Type and Number:
Japanese Patent JP4659179
Kind Code:
B2
Abstract:
The process is characterized in that, if: DTS_next_AUold - PCRold < DTS_first_AUnew - PCRnew, then, in a first step, the data of one or more last images of the old stream and/or one or more first images of the new stream are replaced by data of one or more new preencoded images of which the number is smaller so that the new value of PCRold and/or PCRnew thus obtained satisfies the relation: DTS_next_AUold - PCRold ≥ DTS_first_AUnew - PCRnew, in a second step, TS stuffing packets are inserted between the point of exit and the point of entry so as to make the decoding instants DTS_next_AUold and DTS_first_AUnew coincide. Applications relate to the transmission and storage of programs, as well as to the insertion of advertisements or to regional or local handover.
