Tandberg Television will launch a multi-channel 8VSB demodulator for cable headends at this year’s Cable-Tec Expo in Philadelphia, starting May 11. The TT6330 MediaLink is a cost-effective, compact solution designed to take off-air 8VSB digital television (DTV) signals and demodulate them into individual ASI streams for remultiplexing and remodulation prior to transport through a cable network. The multi-channel capacity of the TT6330 allows cable operators to feed existing off-air transmissions while adding newly established DTV channels to their systems.
Designed as a scalable solution, cable networks can start small and expand the quantity of demodulators as the network’s number of channels is increased. Up to 13 channels of demodulation can be realized in one 3RU chassis, thereby saving valuable rack space over other currently available solutions. When positioned at a central headend or local network hub, the demodulator accepts transmissions directly from the antenna and demodulates them to an ASI format. Those ASI output signals are then forwarded either to a cable headend multiplexer or directly to a digital cable modulator.
