HD why so difficult & expensive?

[tvspecv]

HI EVERYBODY!!!

i just wanted to discuss how i was watching a bollywood movie (asia) on the zee network and the picture was almost (v.v. close) to high def and was wondering this aint a hd channel so if they can achieve such a high standard not being british why is it so difficult for standard channels to achieve such quality?

If it wasnt an HD channel then you were not seeing 720 lines of image just standard def. But that doesnt mean the different SD transmissions might not be of different sharpness since the original camera that took the picture might have been of different quality. So you were watching a good quality SD image....not HD even though the camera might have recorded the movie in HD which accounts for its relative clarity.

It is expensive because sending 720 lines across space is more expensive than sending fewer, because it takes up more bandwidth and more energy to send...basically

why doesnt everyone else use good cameras instead?
tv is mostly pre-recorded not live (unless its sport) so i dont see the problem.

invest in a good camera an claim its hd

shouldnt be a problem

There may be some issues of illegality with what you suggest.

Well I was always asking myself (a good few years ago) why does DVD look so much better the broadcast material when it's all supposed to be SD standard.
Shouldn't everything have been as good as DVD for SD?

So now with HD we appear to be getting something similar, how low can the quality go and still be called HD?

Surely standards are there to be adherred to?

 

[tvspecv]

i agree with digigriffin any dvd upscaled looks fantastic so why the problem?

It really depends on the size of your TV. Upto a certain size, you won't notice much difference between a standard & HD source. I have a 50-inch TV & there is a significant difference between them.

 

[tvspecv]

no not really size doesnt matter its the source (where the picture is coming from)

 

[bigboss]

Yes, source quality definitely makes a difference, & yes, it's strange for Zee TV to have a better quality than many mainstream channels. Probably it's the competition between Asian channels themselves. You get Star as part of the Sky package, Zee has to come up with something special to entice viewers into spending £10 a month on its channels.

Of course it matters what size. I think you seem to be missing a fundamental aspect of this, which is perhaps why you started this thread in the first place tvspecv. Or I have not been understanding your original question

SD signals have less information (hence the cheapness referred to in your original query) in them than HD signals, but a screen is limited by the number and size of dots, so smaller screen can not display more resolution than the number of dots it has which is why SD and HD will look the same on a very small screen. Why? because the extra resolution can not be shown because of the number of dots. This is when you dont need HD, take a 22 inch screen and try and see the difference between HD and SD signals. HD looks better on a bigger screen for the opposite reason.

 

[tvspecv]

okay i see your point but nothing under 37-inches

HD is our free right for investing in new television sets this shouldnt be a premium we didnt pay extra for a clear picture when we had crts why the premium now!?

the license fee we pay every year but no thats not good enough we want more to get you a clearer picture is anybody listening!?
