Product description:
This transmodulator-regenerator of DTT signals is able to extract the transport package (MPEG-2, MPEG-4, ... etc) of the multiplex received, allowing decrypt, edit or even delete the services embedded in it, as well as regeneration of degraded DTT signals. After managing the desired services, the transport package is modulated in a new DTT COFDM regenerated multiplex for distribution in the coaxial network. Total or selective deleting of services from the received Multiplexes to avoid being detected (and stored) by the receiver (STB). Edition of TS_ID to facilitate detection of programs / services in the receiver (STB). Edition of Network_ID, Original Network_ID and Cell_ID to control network IDs. PID filtering, allows you to delete services not interested in a multiplex (exploiting the occupation). Very interesting feature when used with a CAM. Allows you to assign an LCN (Logical Channel Number) to the services present in the output, which facilitates the management of channels in the receiver (STB). It allows the regeneration of the COFDM signal when its impulses are deteriorating and have achieved a degree of degradation that prevents proper decoding by the STB. Given the nature of the digital signal through its regeneration is achieved it is again identical to the original signal.
