1. An apparatus for causing the release of a vestigial-sideband (VSB) frame initialization packet into a distribution network, comprising:
- an offset calculator configured to calculate an offset between a next edge of a pulse signal of a global timebase and a start of a superframe;
a timing calculator configured to calculate a release time based on the offset and a maximum delay value of the distribution network; and
an interface controller configured to control an emission multiplexer to release the VSB frame initialization packet at the release time.

Abstract
Systems, apparatus, methods and computer program products are provided for causing a dataframe to be emitted at an air interface of an antenna. A memory stores a transmission to antenna delay value (TAD). An offset calculator calculates an offset value based on an epoch of a global timebase generator and the transmission to antenna delay value (TAD). An interface controller in communication with the offset calculator communicates a segment synchronization signal and a field synchronization signal based on the offset value.
