Reliance digital TV formerly known as Reliance big TV. I m using a sd connection for couple of months.pic quality and sound quality is awesome.No one can beat it. It is best as a sd connection. Airtel, dish tv, tatasky is not as good as rdtv in SD box. But it's service is not good as tatasky. If you use component cable u can watch better picture quality. In SD box u can have component only in rdtv or in tatasky. So if u want pic and sound quality in SD connection then go for it.
