1080p is slightly superior to 1080i, which is being offered by all other operators. 1080i (interlaced) is the format recorded by HD cams and converted to 1080p (progressive). IIRC, Reliance beams in mp4 format so they can use more channels in given bandwidth. Whether it is 1080i or 1080p, if the frame rate is not 23.79fps and aspect ratio is not 16:9, you are not getting HD. Visually, 1080i and 1080p won't be any different on HD TV. If Reliance is saying all channels in 1080p, be sure it is upscaled.
