Method and apparatus for re-timing a digital signal

摘要

The present invention relates generally to receiving digital signals and more specifically to a method and apparatus for re-timing digital signals. The invention is of particular use in the field of digital video broadcasting. This invention provides a method of receiving a digital signal made up of one or more packets which has been transmitted over a channel. An indicator is applied to each packet of the digital signal. The indicator is characteristic of the relative position of each packet with respect to time. The digital signal is output by releasing each packet when the indicator reaches a predetermined value. The packets can be released in such a manner that any timing errors in the received signal relative to an original transmitted signal are removed.
