TataSky, SunDirect, Dish TV, BIG TV and Airtel Digital has already launched their HD Services. Following procedure gives details on how to connect High Definition Set Top Box (STB) to your HD TV and Home Theater.
Connecting DTH HD STB to LCD TV( HD TV):
Both the HD TV and DTH DH Set Top Box has a HDMI port. All the DTH operators include HDMI cable for carrying HD signals from STB to the HD TV. You just need to connect one end to the STB’s HDMI port and one of the HDMI port in the TV.

Switch on the STB and TV and select HDMI input from your TV remote. You should see the picture and get the sound in the TV. Normally, channels will have the sound in TV without any change in settings. But, HD channels like Discovery, National Geographic(NGC) may not have sound coming in TV. These channels have 5.1 Dolby Digital audio and this will not be decoded by the LCD TV. To get audio of these channels in TV, the STB autio option needs to be changed to stereo( from the digital). But, you will not get teh 5.1 surround in the TV. To get 5.1 effect, the STB needs to be connected to the Home Theater.

Connecting HD STB to Home Theater:

If you are planning to buy one of the DTH, make sure your Home theater receiver has Coaxial S/PDIF input for 5.1 sound. Dish TV Tru HD, BIG TV HD and Sun HD has Optical S/DIF for 5.1 audio. In case you buy one othese, make sure your audio receiver has a Optical port.
