Product description:
The DVB-S2 transmodulator to COFDM receives a satellite transponder in some DVBS (QPSK) or DVBS2 (QPSK or 8PSK) modulation formats and demodulates it by obtaining an MPEG-2 transport package. The TS is then modulated in COFDM format and converted to the output channel (UHF or VHF).
Technical features:
TS settings in order to comply with DVB-T requirements:
1. Stuffing, to perform faster scanning in the STB or when using STB with a fixed symbol rate.
2. MUX services removing to avoid STB detection/loading
Configurable TS identifier in the NIT. It is possible to substitute the satellite descriptor for the DTT descriptor allowing a better STB service detection.
Occupation per service and of the complete MUX COFDM, allowing output space optimization.
LCN (Logical Channel Number) setting to facilitate the sorting of the services in the STB.
