System and method for splicing

A method for splicing a first data stream that conveys a first single program transport stream (SPTS) and a second data stream that conveys a second SPTS, the method includes: receiving first data stream metadata units representative of first data stream packets, second data stream metadata units representative of second data stream packets and a request to perform a splicing operation at a n′th splicing point; performing, in response to the splicing request, transport stream layer processing of the first data stream metadata units and of the second data stream metadata units such as to provide a control output stream; and transmitting an output stream in response to the control output stream.
