Abstract
A method and apparatus for splicing transport streams from multiple sources without violating the clock slew rates specified for a receiver. The method employs a digital phase lock loop (PLL) to lock both the transport output clock of the digital studio and the transmission symbol clock to a stable reference clock of 27 MHz.
