Assume that the average compression ratios of frame I, frame P, and frame B are 1:5, 1:20, and 1:60, respectively. We put the compressed frames in 512 B packets and send them. The header size of each packet is 5% of the size of packet. Each packet contains information on one frame and its header, Each frame can be sent in multiple packets. Picture resolution is 196 × 144 for a video at 32 fps. (a)What is the compression ratio in this pattern? (b)What is the order of coding and transmitting frames in this pattern?
