Group of Pictures

One parameter that can be adjusted in MPEG-4 is the Group of Pictures (GOP) length and structure, also

referred to as Group of Video (GOV) in some MPEG standards. It is normally repeated in a fixed pattern,

for example:

> GOV = 4, e.g. IPPP IPPP ...

> GOV = 15, e.g. IPPPPPPPPPPPPPP IPPPPPPPPPPPPPP ...

> GOV = 8, e.g. IBPBPBPB IBPBPBPB ...

The appropriate GOP depends on the application. By decreasing the frequency of I-frames, the bit rate

can be reduced. By removing the B-frames, latency can be reduced.
