The Televes COFDM-PAL transmodulator enables analogue installations to continue being utilised

Wed, 29/07/2009

The equipment's capacity to transform the DTT signal to analogue offers interesting advantages for hotels, residences and hospitals, or for those who want to continue using their television in exactly the same way as before the arrival of digital television

Santiago de Compostela, 29th July 2009. To continue utilising the large number of analogue televisions installed in hotels, residences or hospitals, or enable elderly people to continue using their television in exactly the same way as they did before the digital switchover are some of the advantages offered by the Televes COFDM-PAL transmodulator. The device is capable of transforming the digital television signal into analogue channels, and can therefore emulate the situation of the radio spectrum prior to the transition to DTT. In this way, a COFDM-PAL headend would be composed by as many modules as analogue output channels to be distributed. An amplifier gives the channels the necessary power for the distribution of the signal in the coaxial network. The headend of transmodulators can be an accessory to the transparent distribution of multiple DTT. The resulting headend would constitute a mixed system in which the signals are distributed in analogue and digital format. Televes has developed this device with those users in mind who need to keep all of their analogue televisions, such as hotels, residences or hospitals, and for elderly people who may prefer to continue enjoying their television in the same way as before the arrival of DTT, with the channels in the same order and without changing the television or the remote control. Advantages for the Installer The COFDM-PAL transmodulator also offers interesting advantages for the installer: * Its vestigial sideband output allows great output voltage, less intermodulation and greater utilisation of the spectrum. * It offers a flexible, configurable and controllable system, in local or remote mode. * It allows mixed headends to be configured in which all the digital packets are distributed and the channels that were traditionally broadcast in analogue format are transmodulated. * It offers output in any channel of the band 47 ... 860 MHz.
