Hi ,
Does any one knows what is the minimum i-frame rate during broadcast?

4-i frames per second is it correct?

please share on this.

Nominal framerate of 60 Feilds per second interlaced meaning 30fps odd/even interlacing. Is that what you were asking?

Hi,
Thanks for response. But that is not my question. You were mentioning about 30 Frames per second or 60 Fields

I am looking for , in MPEG-2 Transport Stream's video data , what is the general minimum i-Frames(Intra frame or independent frames) rate per second.

Like P- frame (Predictive) and B-Frame (Bi-directional Predictable Frame), what is the i-Frame rate per second.

Am i clear about my question?
