Abstract:
A method for splicing a first elementary data stream containing first compressed picture data and a second elementary data stream containing a second compressed picture data to generate a spliced elementary data stream containing a spliced continuous compressed picture data, said spliced elementary data stream being generated by inserting an inserted elementary data stream between an arbitrary splice point of the first elementary data stream and an arbitrary splice point of the second elementary data stream, said method comprising the steps of:providing a virtual buffer for controlling an amount of code data which is generated; detecting a bit occupancy in said virtual buffer at an arbitrary splice point of said first elementary data stream; detecting a bit occupancy in said virtual buffer at an arbitrary splice point of said second elementary data stream; and controlling said inserted elementary data stream so that a first bit occupancy of the inserted elementary data stream in said virtual buffer equals the bit occupancy in said virtual buffer at the arbitrary splice point of the first elementary data stream and a last bit occupancy of the inserted elementary data stream in said virtual buffer equals the bit occupancy in said virtual buffer at the arbitrary splice point of the second elementary data stream.
