LOL You really don't have a clue, do you? There are so many aspects to video. Maybe you should rather try to understand that resolution is one of the least important aspects of video.
Maybe it is that I understand more than you do. My statement really had nothing to do with resolution. Ultra HD is ridiculous, the bandwidth and storage requirements for such a resolution would be crazy.
My point is rather this...
1. DSTv charges a premium for the privilege of getting HD vs. SD, yes?
2. But it's only baby HD (720p).
3. We are on a roller-coaster ride of technological advancement of which at any given moment we are already behind the latest and greatest. BTW 4k (4096 x 2160) is coming believe it or not, care about it or not. A friend of mine has been working on a compression codec for this resolution for the last 3 years at SHARP, in England.
4. Three years ago I was in Canada, and one of their Cable companies had many channels with 1080i content. In SA how many channels are running 1080i, or even 720p? Handful at most.
5. Given that the Japanese government is planning to have Ultra HD standardised by 2020. Implication is SA already doesn't know what it doesn't know, ignorance is bliss in Africa. We can't even get 1080i up and running and technology is marching past us.
On the point of resolution... while I'll agree with you that resolution isn't the only factor regarding video. To say it is the least important shows that either you're stupid (and I doubt that) or you're just expressing an opinion. Which means your comment is actually a flame.
FYI. Here is how resolution impacts video. 1920x1080 = 2,073,600 pixels which at 3 bytes per pixel is 6,220,800 bytes per frame. At 30 fps means 186,624,000 bytes per second (186MB/s) has to be processed and rendered on a PC or in the embedded processor (FPGA or micro-controller) of the TV. Wikipedia says 356Mbps, I'm not sure how they get to that value, they could be taking compression into account. But, regardless of the compression scheme used that is still the final output data rate that must be processed and achieved to render the image to the screen. That is a lot of data and it makes a huge difference to the cost of the hardware used to record, transmit, receive and display the HDTV.
Even if a good codec is used like H.264 the data rates are large (and set to get even larger).
So while we could subjectively argue the merits of 1080p over 720p in terms of perceivable quality, the resolution does make a huge difference to the underlying technology. Larger resolutions means more data, faster data rates and larger more powerful processors to process all that data.
