What is the use of a 576I and 576P Menu ->TVoutput ->componant -> 576I (or)Menu ->TVoutput -> componant -> 576p what happens when we use 576I , What happens when we use 576P
 
576i - Interlaced scanning (Interlace - Wikipedia, the free encyclopedia)
576p - Progressive scanning (Progressive scan - Wikipedia, the free encyclopedia)
These are different method how picture is drawn/displayed on our TV screen. Most TV's support only Interlaced scanning. But LCD/Plasma screens support both.
Progressive gives better picture quality

Hello SVK, thanks for that information.
But I also faced differences in the usage.
For e.g., I have have a favorite with UTV and NDTV.

In 576i -> I chose UTV thro' favorites. After 5 min, I press the down button, I get NDTV ( within the favorites )

In 576p -> I chose UTV tho' favorites. After info menu disappears, I press the down button. I get some other channel as the mode is already switched from "favorite" to "TV"

I tested this several times with same results. Did anybody else experience such differences???

Strange!
Actually FAV channel list & 'Display Option' are independent, don't know why it is happening

Fren this happened to me in 576i as well. I Called and asked CC people... He replied that 'favourite option is not yet available and you hav to wait for somemore time':dance::cool2:
 
576P > 576I because its progressive picture which means better PQ than interlaced. I was frankly surprised to see 576P working using composite video input :O . I thought progressive works only with component video input?!

Hello Shyam,
Thanks for that input. I upgraded to new software ( load : 05 ) last week and this problem is not consistent now. It happens once or twice but not always as before. I tested with 576P.

Thanks,
 
All the channels downstreamed to TV are in 576I anyway. The scaling chip in the STB re-converts to 576P :o . You can see what I'm talking about by seeing the 576I icon in the channel info box
