123 What are the typical coded sizes for the MPEG frames? (MPEG-2)
Typical bit sizes for the three different picture types:
Level
I
P
B
Average
30 Hz SIF
@ 1.15 Mbit/sec
150,000
50,000
20,000
38,000
30 Hz CCIR 601
@ 4 Mbit/sec
400,000
200,000
80,000
130,000
Note: the above example is taken from a standard test sequence coded by
the Test Model method, with an I frame distance of 15 (N = 15), and a P
frame distance of 3 (M = 3).
Of course, among differing source material, scene changes, and use of
advanced encoder models these numbers can be significantly different.
