Doordarshan has launched its first High Definition channel - DD National HD.


DD National HD is available Free-To-Air to downlink in C Band from the GSAT-10 satellite.

Since it is a C band downlink, Cable TV networks are permitted to receive it and retransmit it on their Cable TV networks, as a HD channel also.

DD National HD is available at the same Frequency, Polarisation, SR & FEC as the Standard Definition channels: DD National, DD News, DD Bharati, DD Kisan, DD Urdu, DD India, DD Rajya Sabha. However, the SD channels are all on MPEG-2 while DD National HD requires an MPEG-4, FTA HD STB to receive it.

DD National HD - Downlink
Satellite GSAT-10 @ 83 deg E
Frequency 3885 MHz
Polarisation Vertical
Symbol Rate 27,500
FEC 3/4
Encryption MPEG-4 UnEncrypted


It is surprising that, until the time of writing, DD National HD is not available on FreeDish. For the past several months, FreeDish has been testing downlink of 24 MPEG-4 Doordarshan channels. 6 of these MPEG- 4 channels are FTA while the others are encrypted apparently using Videoguard.

The choice of Videoguard for testing seems odd on government owned FreeDish, given the fact that the Government has developed, deployed and is promoting iCAS as a Conditional Access System.

Cable Networks must note that they are not permitted to retransmit any content from FreeDish on their Cable TV Networks. Only Doordarshan's C-Band downlinked channel can be retransmitted on Cable TV & DTH platforms. n
