Method for the splicing of digital signals before transmission, splicer and resulting signal

摘要

A method is disclosed for splicing digital signals comprising packets of complete data and differential data at the transmission stage, especially MPEG-2 signals. The major reactions are those of erroneous reactions of the standardized decoder (T-STD) owing to the splicing. A splicing method is disclosed, comprising the following steps: receiving a first digital signal s1; receiving a second digital signal s2; receiving a splicing command Cc(T0); transmitting the first signal s1 before the splicing indicated by the splicing command Cc(T0), and transmitting the second signal s2 after the splicing indicated by the splicing command Cc(T0); wherein the transmission of the second signal s2 starts with the I or P packets of complete data closest to the instant To indicated by the splicing command Cc(T0) in such a way that the reproduction of the second signal s2 starts with the reproduction of the I or P packet of complete data.
