For the original broadcast, commercial breaks were heralded with the familiar 7 beat staccato drum (used for scene transitions) inter-cutting with the final scene and the Spectrum Logo zooming out. The resuming of the program was then heralded with a repeat, this time with the opening scene inter-cut with the Spectrum Logo zooming in. Though this is present on DVD and Blu ray releases, for airings on the BBC and original video releases, this was re-edited so that instead of the Spectrum Logo zooming in/out, the closing and opening scenes either side of the commercial break were simply inter-cut with each other making it a standard scene transition.
