let me clear some of the doubts regarding HDTV tranmission. Contrary to belief that bandwidth requirement for high def transmission is high, it takes almost equal bandwidth and this is decreasing day by day as the compression technology becomes better. to put it simple, SD transmission of today is done using relatively inefficient mpeg-2 where as de facto standard for high def is H264 codec ( a flavour of mpeg-4 ) which is highly efficient. So bandwidth is not the problem, it's the cost of new hardware which can handle huge processing needed for this. Also lack of vision by Indian companies is also responsible for this. It's the money which matters and there is nothing wrong with it. Believe me my dear friend, common Indians can't afford the cost of such an investment right now. It's true that you won't be able to see HD transmission for atleast couple of years till it becomes so cheap that even countries like sudan and ethopia makes it available to their people.
