Bangalore, July. 10 (PTI): The failure of INSAT-4C meant that plans on Direct-To-Home television services and digital satellite news gathering of some channels which had booked transponder space, particularly SUN TV, have been hit.

Sun TV had booked seven high-powered Ku-band transponders -- six for DTH, and one for DSNG -- of the total 12 carried by INSAT-4C, the second satellite in the INSAT-4 series.

CNBC, Times TV and Kairali were among those who had booked space for DSNG operations on two transponders while the National Informatics Centre (NIC) had leased three for its VSAT connectivity. Sri Lankan broadcaster Rupavahini is also said have booked space.

The transponders were designed to provide DTH television services, facilitate video picture transmission and DSNG.
