Which is better 1080i or 1080p?

Question

also what is the difference?

Answer 1

To add to the information already given...

1080p is NOT "far better" than 1080i, it is "better"; but you would probably only notice the difference on a screen larger than 47".

You the viewer has no control over the tv scanning system in use at any one time by the tv set. That is, it is not a user-defined item.

The broadcaster (or BD maker) will decide what format the HD transmission will be made in. A component of the transmitted signal gives this information to the reciever. This could be either 720p or 1080i. The tv set will obey the commands sent to it and adjust itself accordingly.

There are no plans to broadcast 1080p pictures at all.  All HD on Sky, cable and Freeview will be either 720p or 1080i. There are sound technical reasons concerning rf bandwidth for this restriction.

1080p pictures are available from many games consoles and some (but by no means all) Blu-ray (BD) discs.

Any of these HD standards will be an improvement over the current standard definition (625i) system.

Please be aware that a large number of programmes currently transmitted on HD channels (especially on Sky 1 HD) were made in Standard Definition so there is no improvement at all.

This is a bit of a "con" on the part of Sky, but we should expect nothing else from that bunch.

Answer 2

1080p

Answer 3

The difference 1080i and 1080p is in the letter at the end.   The i means Interlaced and P Progressive. This is all related to the way the pictures are delivered to the viewer.

A standard TV picture is made up of a series of lines which are displayed and refreshed at a very fast speed, so to the human eye it appears as a consistent image. The difference between progressive scan and interlaced is that progressive scan is delivered line by line and interlaced scan delivers alternate lines of image at a time.

The 1080 number refers to the resolution (pixels) that can be seen. 1920 x 1080 is the standard resolution which signifies a 1080p TV.

Interlaced viewing is traditionally associated with older CRT (Cathode Ray) TV's and the point of the Progressive is to provide a smoother picture as it scans through in sequence.

1080p is good for watching Blu ray and Full HD films for example. Also many gaming systems use games which are upto 1080p quality, so 1080p TV's are ideal.

All flat panels are now designed with the progressive scan functionality, so a 1080i Flat technically does not exist, although a 720p/1080p or (HD/Full HD) ready Panel can usually convert the image.

So to conclude, 1080p is great for gaming and Full HD movies for superb clarity and image quality.

720p (or HD Ready) is good for watching High definition TV (provided you have the correct equipment) and for everyday viewing.

Answer 4

1080p is progressive scan (all the lines show up at once) 1080i is interlaced (flash between half the lines alternately to simulate a denser picture).

1080p by far.

but you should also take into account your source, if you are only transmiting in 720p they will look very close to the same.
