What are intra-coded pictures in MPEG?

問題:

What are intra-coded pictures in MPEG?

答案:

Intra-coded pictures (I-pictures or I-frames) are pictures that are coded by using information present only in the picture itself and without depending on information from other pictures. I-pictures provide a mechanism for random access into the compressed video data. I-pictures employ transform coding of the pixel blocks and provide only moderate compression.
