Remote cueing provides complete control
Cable operator PCCW has acquired a Microvideo HDB 300 to decode WSS cues on delayed news transmissions that are broadcast over the border into Southern China.
The News room and MCR are located in different parts of Hong Kong, so needed a way of remotely controlling play out so that the appropriate sections of programme are censored as required by the authorities. A cue to trigger the censored output was inserted into the VBI space before being sent to the MCR. At the MCR, the cue is decoded by the HDB 300 which then provides a tally signal to enable equipment which blocks transmission of the specific news item.
