Airtel Digital TV
Airtel Digital TV HD provides channels in their native resolution of 1080i or 720p with 16:9 aspect ratio. The STB is compatible with 7.1 Channel Dolby Digital Plus surround sound as well and is in fact the first HD STB in India to be compliant with Dolby digital Plus.. Airtel Digital TV HD+ is a recorder that records content on an external USB drive/ hard disk drive. It is different from the Digital TV recorder that records content on an in-built hard disk drive. HD+ offers potentially unlimited recording, as the capacity depends on that of the external hard disk drive/ USB drive. However, it only has a single tuner and hence only a single channel can be watched and recorded at the same time. This is in contrast to the recorder that enables one to watch and record two different channels at a time and to also supports simultaneous multiple channels recording.
