PURPOSE: In a method of switching from a first to a second video sequence, an additional sequence of k pictures is inserted at the switching point, between the two sequences, in order to avoid the creation of special access points such as splicing points defining in MPEG standard. CONSTITUTION: A method of switching from a first video sequence to a second one, bothold and new sequences being composed of pictures of type T = I, P or B according to the fact that the pictures are independently coded, or predicted from earlier I or P pictures, or bidirectionally predicted from earlier and later P pictures and/or I pictures, wherein an additional sequence of k pictures is inserted at the switching point between the two sequences, k having a value sufficient in order to have compatible sequences and the additional pictures being coded with a few number of bits. |
