Zenith's ATSC PSIP Enhanced VSB Translator for Digital Television

ATSC broadcasts are evolving at an exciting pace. Consumer demand for DTV television receivers is driving the broadcast industry to invest heavily in new production equipment and transmitter technology. Terrestrial Translators will be required to extend the range of these signals to maximize coverage. The ATSC PSIP Enhanced VSB Translator (model # DTVTRANS) offers the ability to coexist with adjacent channels present in the current FCC channel allotment. By using a high quality VSB front-end processor, the translator can be tuned to any terrestrial broadcast channel. Adjacent channels are rejected and in-band noise is removed by the translator, producing a clean baseband MPEG stream. Baseband processing enables the manipulation of the PSIP information to reflect the new channel assignment transmitted by the terrestrial translator system. The PSIP Enhanced signal is then modulated for re-transmission through digital low-power terrestrial transmitters. Zenith's PSIP Enhanced process alters the Virtual Channel Table (VCT) to reflect the new physical channels for both the DTV signal and the Analog signal when available in the PSIP stream. This results in consumers televisions being able to navigate properly using PSIP and also provides broadcasters with the ability to retain their branding and original channel identity.
